Abstract

OBJECTIVE
To compare the short-term efficacy of a glenohumeral posterior mobilization technique versus conventional physiotherapy for the improvement of the range of external rotation in patients with primary adhesive capsulitis of the shoulder.

METHODS
This is a randomized clinical trial conducted at Hospital Clinico San Borja Arriaran in Chile. Fifty-seven patients with an age range of 50 to 58 years old were enrolled in two groups. Both groups were randomized to receive a treatment of 10 sessions: the experimental group (n=29) received a glenohumeral posterior mobilization technique after training with a cycle ergometer, and the control group (n=28) received conventional physiotherapy. The primary outcome measure was range of passive movement in external rotation; secondary outcomes were forward flexion and shoulder abduction, pain perception using the visual analogue scale and functionality test using the Constant-Murley Score.

RESULTS
The study had the statistical power to detect a difference of four degrees between the groups in the improvement of the range of external rotation at the end of the treatment period. The experimental group showed a significant improvement with a mean difference of 46.3 degrees (SD=8.7) compared to 18.1 (SD=7.2) in the control group (p<0.0001). There was also a decrease in the perception of pain (p= 0.0002) and improved function (p< 0.0001) in the group treated with glenohumeral posterior mobilization technique.

CONCLUSIONS
The glenohumeral posterior mobilization technique applied after training with cycle ergometer is an effective short-term technique to treat primary adhesive capsulitis decreasing the severity of pain and improving joint function compared with conventional physiotherapy treatment. The degree of increase in shoulder external rotation is more than 20 degrees beyond the increase achieved with conventional treatment.


 
Introduction

Adhesive capsulitis is a common musculoskeletal condition characterized by shoulder pain of spontaneous onset, associated with progressive loss of scapulohumeral motion and its etiology is unknown. Many terms have been used to define this clinical condition.  It was first described by Duplay in 1896 who called it “scapulohumeral periarthritis[1].  Later in 1934, Codman coined the concept of “frozen shoulder” [2].  Nevertheless, current literature views this concept as very broad and it could cause confusion since it involves different pathologies which present as pain and shoulder stiffness; such as calcific tendonitis, bicipital tenosynovitis, glenohumeral and acromioclavicular arthritis and break of the rotator cuff [3],[4],[5],[6],[7].  Neviaser, during the pre- arthroscopic era,  was the first one to use the concept of “adhesive capsulitis[8],  to describe findings of chronic inflammation and fibrosis of the joint capsule, although arthroscopic examination would support the term fibrotic capsulitis with absence of intra-articular adhesions [9],[10].

In 1944 American Shoulder and Elbow Surgeons (ASES) defined it as “a condition characterized by functional restriction of both active and passive shoulder motion for which radiographs of the glenohumeral joint are essentially unremarkable except for the possible presence of osteopenia or calcific tendonitis” [11].  Zuckerman suggested a type of classification where primary or idiopathic adhesive capsulitis was not associated with some systemic condition or trauma; there was no previous event to attribute to this condition, so its etiology is unknown [11],[12].

It is considered as a self – limiting disease. Reeves et al. [13] based on adhesive capsulitis natural history distinguished three sequential stages (painful, stiffness and recovery stage). Later Hannafin and Chiaia [14] described four stages, including the arthroscopic stages described by Neviaser [4], clinical examination and histological findings. Stage 1, Pre-Adhesive Stage: duration of symptoms 0-3 months; pain with active and passive range of movement with gradual limitation in the middle range and all final shoulder movements.  From an histological point of view, there is only diffuse glenohumeral synovitis. Stage 2 or Freezing Stage: duration three to nine months; patients frequently have a high level of pain near end-range of movement with significant limitations related to shoulder mobility. Histologically, there are hypertrophic and hypervascular synovitis, fibroplasia and scar formation in the underlying capsule. Stage 3 or Frozen Stage: duration 9 to 15 months; there is minimum pain, but only in extreme ranges; limitation in all shoulder movements is important. Histologically there is not synovitis nor hypervascularity, but there is more fibrosis and joint capsule density is increased. Finally Stage 4 or Thawing Stage: duration 15 to 24 months; patients present gradual and spontaneous recovery and shoulder mobility and function.

Despite the acceptance of this classification in literature, its usefulness from the clinical point of view is controversial, because pain and range of motion limitation are present in all adhesive capsulitis stages. Besides, in many cases the previously described chronological sequence has not been observed, since there are patients who have suffered from pain and range of motion limitation for more than two years; even 10% of them never reach total range of motion of the affected shoulder [15],[16],[17].

Kelley et al. [18] have proposed a classification system based on patient´s irritability level.  It could be a very useful guideline in order to make decisions about therapeutic procedures for adhesive capsulitis treatment. Under low irritability, according to the visual analogue scale, patients show pain < 3/10, neither nocturnal pain nor at rest, and the final pain sensation is tolerable; active movement limitation is similar to passive movement and both present low levels of disability. These patients generally inform having stiffness rather than pain as the main complaint. High irritability patients show pain >7/10 in a visual analogue scale, mainly with passive movement, nocturnal pain and at rest; they report high levels of disability.  These patients generally inform pain rather than stiffness as the main complaint.

In spite of the fact that there is no specific diagnostic criterion, patients with primary adhesive capsulitis show coherent history in the clinical exam [4],[8],[13]. Regarding clinical presentation, there are specific factors that are useful to determine patient´s level of irritability [18]. First, the capacity to sleep through the night means less irritability and it is indicating that synovitis / angiogenesis   begin to resolve and they are at stage 3. The second factor has to do with pain or stiffness as a predominant symptom; in this case, the patient experiences more stiffness than pain and he probably has less symptomatic synovitis /angiogenesis and more fibrosis. The third  factor  has to do with  symptoms having  improved or got worse over the last three weeks; improving symptoms might indicate that the patient  has  advanced  from  stage 2  to  stage 3 and irritability level  has decreased. This is very important because the effects of therapeutic agents, especially physiotherapy techniques and physical agents employed to treat this medical condition, are closely related to the ability of the affected tissue to withstand stress or mechanical load, concept often described as "tissue irritability " [19].

According to current knowledge of natural history of the disease, the traditional concept of benign nature and self-limited course is controversial [5],[13],[20],[21],[22], because there is a percentage of patients whose symptoms, mainly range of motion, will not solve spontaneously, being external rotation the most restricted physiological movement [20],[23],[24]. To treat this impairment some physiotherapy techniques are prescribed.  The use of some physical agents in combination with an exercise program has shown benefits in the improvement of movement range at all levels [20],[21],[25],[26], except for shoulder rotations [27]. Some studies have shown that manual therapy decreases the deficit of glenohumeral rotational movement, characteristic of this condition, especially the external rotation [24],[28],[29],[30]. In the literature, one of the most widely studied technique for this purpose is the glenohumeral posterior mobilization (GPM) [31],[32],[33],[34]. It is a high-degree joint mobilization technique, where a humeral axial distraction type III (according to Kaltenborn) is carried out and a kept glide or slide  in posterior direction of the humeral head towards the end of glenohumeral range of motion available. Its foundations are based on the elongation of the posterior capsule through the application of stress, reaching the plastic phase of such structure by changing its shortening through permanent deformation [35], allowing the movement of the humeral head on the glenoid cavity [31],[32],[33],[34].

In this study, we compared therapeutic effectiveness of two treatment modalities in patients with shoulder primary adhesive capsulitis diagnosis: one of them is a glenohumeral posterior mobilization technique after training with a cycle ergometer, and the other one is a conventional physiotherapy program based on ultrasound application, active and self-assisted ROM exercises and isometric exercises.

Methods

This is a randomized clinical trial conducted in the Physical Therapy Department of Hospital Clinico San Borja Arriaran in Chile, under the approval of the Central Metropolitan Health Service Ethics Committee. From 2009 to 2013 fifty-seven patients with primary adhesive capsulitis were enrolled. An orthopedic surgeon based on medical records, clinical symptoms and imaging studies, made the diagnosis. All patients received non-steroids anti- inflammatory drugs, oral analgesics and physiotherapy. At the beginning of the therapy, the average time of the emergence of their illness was five months.  All subjects signed a consent form approved by the institutional ethical committee and before their first assessment; patients were randomly assigned to each protocol treatment.

Passive range of motion was measured for external rotation, forward flexion and glenohumeral abduction. Pain perception was assessed through a visual analogue scale and the functionality degree was determined by Constant-Murley Score (CMS). Evaluations were done during the first and the tenth sessions.

Inclusion and exclusion criteria

  • Patients derived from the Traumatology Department who suffered from unilateral primary adhesive capsulitis of shoulder were included, based on clinical and imaging criteria (history, X Ray, ecotomography and /or nuclear magnetic resonance).
  • Patients who accepted and signed the informed consent were included.
  • We excluded patients with adhesive capsulitis secondary to: shoulder surgery; humeral, acromion or clavicle fractures; external and internal impingement syndrome; partial and / or full break of the rotator cuff; clinical history of glenohumeral instability (labrum injuries, Bankart, SLAP, Hill Sach); backgrounds of atrophy or shoulder muscle paralysis; Braquial plexus injuries or stroke.
  • Patients with a high level of irritability were excluded (according to Kelley et al.[18])
  • Patients who have undergone non-steroids anti- inflammatory drugs infiltration and /or corticosteroids in the last 6 months were excluded.
  • Patients previously treated with release technique and /or manipulation under anesthesia were excluded.

Sample size- hypothesis
The sample size calculation was performed using the Epidat 4.1 program. The necessary initial data was based on a randomized clinical study conducted by Carette et al. [26]. They used a conventional physiotherapy treatment similar to our study, in which, at the end of the tenth session, they reported a mean improvement of 9.6 degrees with a standard deviation of 3.2 degrees for the range of passive external rotation movement. Therefore, this 3.2 was considered as the initial value of the common standard deviation and that variable was selected to calculate our sample size. It was found that for α= 0.05 (probability of committing Type I error) and a statistical power of 80% to detect a minimum difference of 4 degrees of improvement between treatments, a minimum of 25 patients per group was needed.  According to this result, authors have stated as a working hypothesis, that there is at least a difference of 4 degrees between increases in passive range of motion of external rotation for the group treated with the glenohumeral posterior mobilization technique after training with a cycle ergometer compared with the conventional physiotherapy treatment program.

Randomization and blinding
Participants were assigned to groups  by a sequence of random numbers generated by a computer program before the beginning of patients selection. The number assigned to each group remained in a sealed envelope with the number visible on the outside. Each selected patient was assigned a number by order of arrival. Thus, the envelope corresponding to each patient (by number) would be opened as near the beginning of treatment as possible. The purpose of this was to conceal the allocation to the researcher who was deciding the entry of the study subjects.

Given the nature of the therapeutic interventions studied, the physiotherapist could not be in blind condition. However, the evaluator was external to the research group, and when measuring the study variables in the first and tenth sessions, he did not know to which group each patient belonged.

Interventions
Experimental group was treated for 15 minutes with upper extremity cycle ergometer and then the glenohumeral posterior mobilization technique was performed, with the patient in the supine position, in 30º to 40º of abduction and a light external rotation of the shoulder depending on tolerance. First, an axial distraction type III was made according to Kaltenborn, followed by posterior glide during one minute without oscillations. This maneuver was repeated 15 times with one minute rest for each. Control group received a conventional physiotherapy treatment program consisting of ultrasound (1MHz, 1.5 W/cm2 continuously for 10 minutes within 4 cm2), self-assisted exercises, Codman exercises, Swiss ball exercises and isometric exercises depending on tolerance [26]. Both groups performed 10 sessions, twice or three times a week.

Operational definitions of variables
In both groups, a physiotherapist external to the research group conducted the evaluations.  The professional has a post degree in orthopedic manual therapy (Master) and more than five years of experience in the clinical area.

Primary outcomes
Both groups were evaluated with goniometer, passive range of motion was measured for external rotation, forward flexion and glenohumeral abduction. A Bioperson ® goniometer of 360º, 18-cm arms and an extension of 54 cm was used. Participants were evaluated in the supine position with as little clothing as possible in order to not alter or obstruct the upper extremity valuation. This measurement has shown to be a reproducible method for evaluating the passive range of motion in patients with adhesive capsulitis [36].

Secondary outcome measures
To assess pain a visual analogue scale (VAS) was used. This consists of an horizontal line of 10 cms length, where the left end represents cero or without pain and the right end represents 10 or the worst imaginable pain. The pain visual analogue scale measurement is self-completed by the subject. The respondent is asked to place a line perpendicular to the visual analogue scale line at the point that represents his/her pain intensity. It is a simple and reproducible valuation method [37], which has proved to be valid in chronic pain conditions [38].

Functional valuation was measured through the Constant-Murley score.  The first two values are subjective valuations based on the patient’s interview.  A maximum of 15 points were assigned to pain and 20 points were assigned to function (daily routine activity).  The other two assessed values are more objective; active range of motion has got a maximum score of 40 points and muscle strength 25 points, adding a maximum punctuation of 100 [39]. This functional rating scale has a high correlation with other scales and shoulder specific questionnaires [Western Ontario Rotator Cuff Index (WORC), Penn Shoulder Score, Simple Shoulder Test, Questionnaire Shoulder Oxford, Oxford Shoulder Instability Questionnaire (OSIQ) or Subjective Shoulder Rating System].  It also shows high reliability and sensitivity [40].

Statistical analysis
Data on quantitative variables are presented as average and standard deviation. To compare the initial baseline data regarding the variables gender and dominant side affection, a Chi-square test was used. For each quantitative variable, normality was first assessed with a Shapiro test. The comparison between groups for these variables is then performed using Student's t test or Wilcoxon test (Mann-Whitney) for two independent samples according to the results of normality assessment. In both cases, the level of significance was set at 0.05. Considering the size of the sample, the confidence intervals of 95% for the mean differences between groups were calculated by the conventional method for all quantitative variables. Statistical analysis was performed using Stata IC program11, Epidat 3.1 and 4.1.

Prior to the study, the authors considered an analysis of intention to treat so that if there is loss of information, these patients would not be excluded from the final statistical calculation and the analysis of results (Figure 1).

Figure 1. Flow diagram of patients through the phases of the trial.

Results

In this study, the statistical analysis was performed only per protocol. It was not necessary to make an intention to treat analysis, since there were no losses. Based on it, outcomes were obtained from all the patients included in the trial. The initial baseline results of each group are presented in Table 1.The normality hypothesis was not rejected for the variables: external rotation passive range of motion (p= 0.52), forward flexion (p=0.30) and abduction (p=0.68); accordingly, t-test was used for comparison between groups regarding these variables. Neither of the variables evaluated at baseline showed statistically significant inter groups differences (all p-values were above 0.2).

At the end of the treatment protocols, both groups showed improvements in all of the evaluated parameters. Table 2 shows the average values of the variables evaluated at the end and the differences between the final and the initial value. For all the variables, the hypothesis of equality of means in the population was rejected and the experimental group was favored, this is reflected in the confidence intervals for the differences between groups.

Table 2. Summary results for variables measuring response to treatment.

For the analysis of visual analogue scale and Constant-Murley score, the test results were Shapiro p=0.03 and p=0.045 respectively. According to this, the Wilcoxon test was used to compare both groups. For both variables a difference statistically significant was found in favor of the experimental group:  visual analogue scale shows a decrease of 2.7 cm compared with 1.4 centimeters (p= 0.0002). For the Constant-Murley score, the score increased by 38.9 points compared to 18.1 points (p <0.0001). In all comparisons between the groups, the p-value was less than 0.0002. The confidence intervals reaffirm the hypothesis of superiority of the treatment with glenohumeral posterior mobilization technique versus conventional physiotherapy treatment.

Discussion

In this study, two groups of patients with primary adhesive capsulitis were treated with two different modalities. One group was treated with a high-degree of joint mobilization technique, applied in posterior way in the end range of available motion in conjunction with cycle ergometer training.  The other group was treated with a conventional physiotherapy treatment program.

Data for both groups at baseline were statistically similar.  The 82.1 to 79.3% of the sample were women, and the average startup time of treatment was five months from the onset of symptoms. Regarding dominance, from 75 to 79.3% of patients had the dominant side affected. In relation to measurements of passive movement range of external rotation, forward flexion, abduction and Constant-Murley score were similar in both groups. At the visual analogue scale, the experimental group had an average slightly higher than the control group, although this difference was not statistically significant (p = 0.41). Regarding the development of treatment, all patients completed their respective therapeutic programs, no dropouts occurred, and there were no reports on any problems about the tolerance of the technique and / or the doses applied. At this point, it is essential to exclude patients with high irritability. The frequency of the sessions was two to three times per week, with total treatment duration of five to six weeks.

Although this study is not aimed at performing a cost analysis, the experimental group sessions had an average duration of 35 minutes, compared to two hours 45 minutes of the control group. We believe that the cost-effectiveness aspect should be considered in subsequent studies.

When reviewing the literature on the effects of different manual therapy techniques in improving the range of movement in patients with primary adhesive capsulitis; the systematic review of Ho et al. [41] and Favejee et al. [42] reported moderate evidence for short and long-term in favor of  the techniques of high-degree of mobilization applied at the final range of motion available. Meanwhile, from the systematic review of Jain et al. [43] these techniques are strongly recommended for the improvement of the passive range of motion in stages 2 and 3 of the adhesive capsulitis.

The results of this study show that the glenohumeral posterior mobilization technique applied after a limb cycle ergometer training,  was effective in treating motion deficits commonly found in patients with AC, especially passive range of  motion of external rotation. Our results are consistent with those in the literature [29],[30],[31],[32],[33],[34],[44], where it can be seen that the range of external glenohumeral rotation increases significantly in the short and long term by applying a high-degree technique of joint mobilization in posterolateral direction, maintained and applied in the final range of motion.

However, there are at least two methodological aspects that differentiate this study from other randomized trials published. The first is that this study compares the glenohumeral posterior mobilization with conventional treatment; other studies have compared manual therapy techniques [32],[34], the same technique in different directions of application [31], or the addition of the technique to a treatment program [33],[34]. The second is that this study includes the irritability aspect in the selection of patients, as some studies have reported that there is a percentage of patients who do not tolerated well high-degree of mobilization techniques. It is important to consider that the glenohumeral posterior movement is a III-degree technique according to Kaltenborn, performed in the final range of available movement. Therefore, the technique is likely to be annoying and / or painful, especially in patients who present adhesive capsulitis, in which pain predominates over the limited range of motion. Because of this, it was relevant, within the exclusion criteria, to exclude patients with high irritability, who most likely would not have tolerated the technique optimally.

In this regard, in the randomized clinical study Vermeulen et al. [34] it was established an inclusion criteria of patients in phase 2 of the adhesive capsulitis, with an eight-month average of progression of symptoms.  However, this study does not describe the tolerance of patients treated with high degree technique of mobilization and the reason why it had two turnovers in each study group.

The randomized trial of Johnson et al. [31], founded on their selection criteria, assumed that the patients in their study were between phases 2 to 4 according to Neviaser [4]. However, they reported that for the group treated with anterior mobilization, only three of the 10 patients had sufficient decrease of pain and passive range of motion to tolerate increased stretching force, as a result of the dose of the technique in the prone position. For the group treated with posterior mobilization, three of the eight patients tolerated the treatment. In the randomized clinical trial of Yang et al. [32], patients had an average of 20 weeks from the start of the symptoms. The authors note that one of the factors that influence the success of the technique is that the patients were in phase 2 according to Reeves [13].

Although they do not refer to tolerance, to the ninth week of treatment five of the 28 patients were lost. The poor performance is attributed to the mobilization technique in the middle range. In the randomized clinical trial of Yang et al. [33], patients had an average of 17 weeks from the onset of symptoms. For this reason, they were in the stage of stiffness according to Reeves [13]. There is no reference to the tolerance of the technique studied. Finally, in randomized clinical trial of Sharad [44], patients had an average of four and a half months from the onset of symptoms and they do not mention the tolerance of the patient to the manual therapy technique studied.

The effectiveness of high mobilization techniques is based on distension and elongation of periarticular structures that happens when a joint has been subjected into its maximum range of arthrokinematic motion [45]. This concept refers to the physical components of stress- strain curve, which studies the behavior of the tissue when it has been subjected to a load, demonstrating that its properties will vary progressing from an elastic phase to a plastic phase [35]. Complementary to this, it has been suggested that apart from the movement degree, it is also very important the type of load that the structure is subject to, considering the length and direction of movement, where the position of the joint  is also of fundamental importance. In the case of glenohumeral posterior mobilization, it is applied to the glenohumeral joint at rest, maintaining a range of 40º of abduction.  Then, an axial distraction begins to the inferior sense of the humerus (grade III according to Kaltenborn), which causes passive elongation of periarticular components.  Through this, joint contact zones are minimized and from this, glide is added posteriorly in a sustained manner, generating maximum elongation of the posterior portion of the joint capsule [31], whose function is to limit the posterior movement of the humeral head in 40º- 45º of abduction [46].

The asymmetric capsular-ligamentous tension has great impact on the movement of the humeral head. Harryman et al. [47] was the first to report that tension of the rotator interval produced a reduction in inferior and posterior translational movements of the humeral head.  After performing a cadaver study [48], they showed that tension of the rotators interval not only limits the range of glenohumeral movement, but also causes a forced translation of the humeral head in antero-superior direction. In this way, it limits the posterior translation associated with external rotation. Due to the role of the capsule in this disease, the concave-convex rule does not have great implication regarding the direction and/or the application of arthrokinematic movement of the different joint mobilization techniques [49]. For this reason, passive glide at the end range of motion performed in the sense of restriction (toward posterior) produces an immediate and significant improvement of the excursion range of the humeral head, getting an increase in rotational movement [31],[32],[33],[34].

Study limitations
The main limitation of the present study is the absence of follow-up after treatment ends, which does not allow establishing the effectiveness of both protocols in the medium and long term. The blinding of patients and physiotherapist, is impossible to perform considering the nature of the interventions studied. The results of this study cannot be extrapolated to patients with secondary adhesive capsulitis; clinical studies are needed to evaluate the effectiveness of this technique in this population.

Conclusions
The glenohumeral posterior mobilization applied after training with cycle ergometer is an effective short-term technique; it showed a significant increase of external rotation of the shoulder. This treatment also reduces pain and improves function compared to a conventional physiotherapy treatment, once completed 10 sessions of treatment in patients with primary adhesive capsulitis.

INTRODUCCIÓN
Demostrar la efectividad a corto plazo de la técnica de movilización posterior glenohumeral, en la mejoría del rango de rotación externa en pacientes con capsulitis adhesiva primaria de hombro.

MÉTODOS
El presente estudio clínico aleatorizado, fue realizado en el Hospital Clínico San Borja Arriarán, donde 57 participantes en un rango de edad entre 50 y 58 años, fueron asignados de forma aleatoria a uno de dos grupos de tatamiento. A ambos grupos se les dio un tratamiento de 10 sesiones. El grupo experimental (n=29) recibió la técnica de movilización posterior glenohumeral luego de un entrenamiento con cicloergómetro. El grupo control (n=28) participó de un programa de tratamiento kinésico convencional. La medida de resultado primaria fue el rango de movimiento pasivo de rotación externa, las mediciones secundarias fueron el rango de flexión anterior y abducción, la percepción del dolor se midió con la escala visual analógica y la funcionalidad usando el puntaje de Constant-Murley.

RESULTADOS
El estudio fue diseñado con potencia estadística para detectar una diferencia de cuatro grados en el rango de rotación externa entre los grupos al finalizar el tratamiento. El grupo experimental mostró una mejoría significativa con un promedio de la diferencia de 46,3 grados y desviación estándar 8,7 grados en comparación con el grupo control con 18,1 grados y desviación estándar 7,2 grados (p<0,0001). También hubo una disminución en la percepción del dolor (p=0,0002) y mejoró la funcionalidad (p<0,0001) en el grupo tratado con movilización posterior glenohumeral.

CONCLUSIONES
La movilización posterior glenohumeral aplicada luego de un entrenamiento con cicloergómetro es una técnica efectiva a corto plazo en el manejo terapéutico de la capsulitis adhesiva primaria. Este tratamiento disminuye el dolor y mejora la función comparado con un tratamiento kinésico convencional. El grado de incremento en la rotación externa de hombro supera en más de 20 grados al tratamiento convencional.
