Poor Results After Arthroscopic Treatment of Irreparable Rotator Cuff Tears Using a Subacromial Balloon Spacer.

Arthroscopic balloon spacer arthroplasty (BSA) is a relatively recent procedure for patients with irreparable rotator cuff tears, conceived to prevent degenerative joint changes and relieve subacromial pain. This is a retrospective case series of 16 consecutive patients treated with BSA and followed up for a minimum 12 months. Besides BSA, partial tendon repair was done whenever possible. Radiographical parameters such as acromiohumeral distance and Hamada stage were measured preoperatively and postoperatively. Range of motion, functional results (Constant score; Simple Shoulder Test; American Shoulder and Elbow Surgeons score; and Disabilities of the Arm, Shoulder, and Hand score), health-related quality of life results with the EuroQol Five Dimensions tool, complications, and patient satisfaction were also analyzed. The mean age was 64 ± 10.3 years, and the male/female ratio was 6/10. Partial repair was achieved in five patients (31.2%) and did not influence functional or health-related quality of life results ( P = 0.11). The mean acromiohumeral distance and Hamada stage worsened from preoperative measures (3.7 ± 2.0 mm and 2.3 ± 1.1) to final follow-up measures (3.1 ± 2.4 mm and 3.1 ± 1.3). Shoulder abduction increased by 7.8° ± 26.8° and forward flexion decreased by 25.5° ± 32.4° after surgery. The functional results at the final follow-up were Constant 49.5 ± 18.0; American Shoulder and Elbow Surgeons 60.2 ± 27.2; Simple Shoulder Test 8.5 ± 4.6; and Disabilities of the Arm, Shoulder, and Hand 32.7 ± 12.1. The mean index value for the EuroQol Five Dimensions was 0.79, and perceived quality of life was 85.6 ± 15.4 of 100 points. 62.5% of the patients (10) were satisfied with surgery. The complication rate was 13% (2), accounting for one deep infection and one balloon migration. Theoretical benefits of BSA for delaying superior humeral head translation and arthropathic changes could not be demonstrated in our series. Its functional results and satisfaction rates are low, but self-reported quality of life after surgery does not seem impaired. Complications do not occur frequently but require reintervention and endanger joint viability. Level IV (case series).

Ultrasound-Tailored Treatment of Subacromial Shoulder Pain

Background and Objectives: Subacromial shoulder pain is the most common cause of shoulder pain consultation in musculoskeletal practice. Partial supraspinatus tendon tears have frequently been treated using a subacromial corticosteroid injection or surgery. The clinical use of a platelet-rich plasma (PRP) injection is an alternative treatment method for the condition, despite the paucity of evidence of its efficacy. The objective of the study was to assess the clinical effectiveness of autologous PRP in comparison to steroid injection in terms of pain relief and functional restoration in subacromial shoulder pathology. Methodology: All the patients above 18 years of either sex presenting with complaints of shoulder pain and painful abduction and elevation of arm for more than 6 weeks and not received any steroid injection in the previous 6 months were included in the study. In intra-articular PRP (IA-PRP), i.e., test group, 20 patients received 3 ml of single IA PRP injection, and in the steroid group (control group), 20 patients received 1 ml of intra-articular corticosteroid (IA CS) into glenohumeral joint under ultrasound (US) guidance. All patients were prospectively followed for 6 months. Results: There were no differences in visual analog scale (VAS) and disability scores between the PRP and corticosteroid groups at 1-month follow-up. However, the PRP group had better scores than the corticosteroid group on both the VAS and disability scores at 3- and 6-month follow-up. The VAS and disability scores did not change significantly at 6-month follow-up in the corticosteroid group; however, the PRP group showed continued improvement in both VAS and disability scores between 1- and 6-month follow-up. The PRP group had better scores than the corticosteroid group on shoulder range of motion after postintervention follow-up after 1 month. There were no complications in either group. Conclusion: Both subacromial PRP and corticosteroid injections had a positive clinical response in the treatment of shoulder pain. In view of the reached results, it may be assumed that steroid injections may provide symptomatic relief but not promote healing which makes PRP injection a good alternative as it is simple, easy to use, easily available, prepared from patient's own blood, and cost-effective. US-guided injections may increase the efficacy of accurately targeted injections.

Effects of A Progressive Rehabilitation Program on Shoulder Internal Rotation Range of Motion, Acromiohumeral Distance, And Pain in An Adolescent Female Swimmer with Subacromial Pain (Impingement) Syndrome

Shoulder injuries are common in competitive youth swimmers because of sport-specific changes in upper extremity physical characteristics and acromio-humeral distance (AHD). These physical alterations could cause abnormal scapular kinematics and positioning. Subacromial pain syndrome (SPS), scapular dyskinesis, and SLAP lesions require a multiphase approach. A 14-years-old female athlete who has been swimming for 7 years had SPS symptoms for 14 months. She also had scapular dyskinesis and suspected SLAP lesion. She received 15 treatment sessions. We conducted a progressive and comprehensive rehabilitation program consisting of electrotherapy, thermal agent, mobilization techniques, posterior shoulder stretching exercises, upper and lower extremity strengthening, proprioception, scapular stabilization, and core stabilization exercises, rhythmic stabilization exercises, plyometric exercises, and the advanced thrower’s 10 program. Internal rotation range of motion (IRROM) with bubble inclinometer, pain with Visual Analog Scale, and AHD with ultrasonographic imaging were assessed before treatment and at the end of the 9th and 15th treatment sessions. Before treatment, IRROM was 52°, AHD was 10.67 mm, and pain intensity at rest and during swimming was 0 and 3.1 cm, respectively. After 9 treatment sessions, IRROM was 55.6°, AHD was 11.62 mm, pain intensity at rest and during swimming was 3.7 cm and 5.1 cm, respectively. At the end of the treatment, IRROM was 58.33°, AHD was 12.02 mm, pain intensity at rest and during swimming was 0 cm. A progressive and challenging rehabilitation program may positively change the scapular and glenohumeral kinematic patterns leading to an increase in AHD and IRROM, therefore a decrease in pain.

Capacitive resistive monopolar radiofrequency at 448 kHz plus exercising versus exercising alone for subacromial pain: A sham-controlled randomized clinical trial

Objective To investigate the effectiveness of thermal and sub-thermal capacitive-resistive monopolar radiofrequency at 448 kHz plus exercising compared to sham radiofrequency plus exercising on pain, functionality, and quality of life in patients with subacromial pain. Design Randomized, controlled, parallel, double-blind, three-arm clinical trial. Setting Hospital and Primary Care. Subjects Eighty-one participants with subacromial pain in three intervention groups. Interventions Three interventions with capacitive-resistive radiofrequency (thermal, sub-thermal, and sham) over 9 sessions (3 per week) plus an exercising protocol identical for all groups over 15 sessions (5 per week). Outcome measures Visual analogue scale and pressure pain threshold for pain, Shoulder Pain and Disability Index and Quick-Disabilities of the Arm, Shoulder and Hand for functionality, and quality of life via the European Quality of Life-Five Dimensions were assessed at baseline, immediately posttreatment, and 1 month and 3 months post-intervention. Results No between-group differences were found in the pain visual analogue scale (F = 1.0; P = 0.37), Shoulder Pain and Disability Index (F = 1.0; P = 0.36), European Quality of Life-Five Dimensions (F = 0.76; P = 0.47), and pressure pain (F = 0.14; P = 0.86) outcomes, with a statistical power < 0.30 for all comparisons. Between-group differences were found in the Quick-Disabilities of the Arm, Shoulder and Hand (F = 3.4; P < 0.038), with an improvement of −14.1 points (confidence interval at 95% (95% CI) −28.1 to −0.1) in the thermal versus the sham group at 1 month follow-up. The mobility dimension of European Quality of Life-Five Dimensions improved in a greater proportion of participants in the thermal group (22.2% thermal, 7.4% sub-thermal, and 0.0% sham; P = 0.02) Conclusion Adding thermal radiofrequency to exercising can further improve slightly functionality and mobility in people with subacromial pain in the short term, but not pain perception. Future studies with larger sample sizes are warranted to increase statistical power.

Causal mechanisms of a scapular stabilization intervention for patients with subacromial pain syndrome: a secondary analysis of a randomized controlled trial

BackgroundCausal mediation analysis is one way to bridge this gap by exploring the causal pathways of a given intervention. The aim of this study was to assess whether scapular motion, position, and periscapular muscle strength are mediators for pain and shoulder disability outcomes following a scapular stabilization intervention for patients with subacromial pain syndrome.MethodsSixty patients were randomized into two groups: scapular stabilization or periscapular strengthening exercises. The intervention consisted of three sessions per week for 8 weeks. The primary outcome measures were pain and disability and the following outcome measures were considered as potential mediators: scapular motion, scapular position, periscapular muscle strength, age, duration of symptoms, and side of the complaint. A model-based inference approach with bootstrap simulations was used to estimate the average causal mediation effect, average direct effect, and the average total effect from the data of a randomized clinical trial that evaluated the effect of adding scapular stabilization exercises to a scapulothoracic strengthening program in people with subacromial pain syndrome.ResultsThe results demonstrated that none of the putative mediators were influenced by the intervention. However, muscle strength of serratus anterior, upper, middle, and lower trapezius muscles was associated with shoulder disability.ConclusionScapular kinematic and periscapular muscle strength did not mediate the effect of scapular stabilization exercises on shoulder pain or disability scores in subjects with subacromial pain syndrome. Muscle strength of serratus anterior, upper, middle and lower trapezius were associated with shoulder disability scores at 8-weeks follow-up.

Tailored exercise and manual therapy versus standardised exercise for patients with shoulder subacromial pain: a feasibility randomised controlled trial (the Otago MASTER trial)

Comparison of Shoulder Total Rotational Range of Motion and External to Internal Rotation Strength Ratio between Assembly Line Workers with and without Subacromial Pain Syndrome

Background Subacromial pain syndrome (SAPS) is one of the causes of shoulder pain in workers performing repetitive upper extremity movements. However, there have been no studies on physical characteristics such as shoulder total rotational range of motion (ROM) and external to internal rotation muscle strength ratio of workers. Purpose The purpose of this study was to compare the total rotational ROM and external to internal rotation muscle strength ratio in workers with and without SAPS. Study design A cross-sectional study Methods This study included 35 workers with SAPS and 32 workers without SAPS. The total rotational ROM were measured using Smart KEMA motion sensor, and external to internal rotation muscle strength were measured using Smart KEMA pulling sensor. Results The results showed that there were significant differences in the total rotation ROM between the groups (<italic>p</italic>&lt;0.05). However, no significant difference was found in the external to internal rotation muscle strength ratio (<italic>p</italic>&gt;0.05). Conclusions Assembly line workers with SAPS had limited total rotational ROM. However, the ratio of external to internal rotation muscle strength ratio was not different for workers without SAPS. These characteristics can be considered factors that should be considered in evaluating workers with SAPS and establishing a treatment plan.

Effectiveness of Scapular Stabilization Versus Non-Stabilization Stretching on Shoulder Range of Motion, a Randomized Clinical Trial

Background Previous research has demonstrated the benefits of both stabilization and non-stabilization of the scapula during stretching in individuals with posterior shoulder tightness, but limited evidence exists in patients with shoulder pain. Hypothesis/Purpose The aim of this study was to determine the effect of stabilized scapular stretching on patients with shoulder pain. The primary hypothesis of this study is that stabilized scapular stretching will improve glenohumeral motion and pain compared to non-stabilized stretch program. A secondary hypothesis of this study is that stabilized scapular stretching will produce greater improvement in function compared to the non-stabilized stretching program. Study Design Randomized Clinical Trial Methods Sixteen patients with sub-acromial pain associated with tendinopathy and associated pathologies presenting to physical therapy were randomized into two groups (stabilized or non-stabilized scapular stretching). Baseline pain and range of motion were measured prior to and following each treatment session for three visits that occurred over the course five to seventeen days depending on the patients availability. The dependent measurements were stabilized horizontal adduction, stabilized internal rotation, stabilized shoulder flexion, non-stabilized shoulder flexion, and current pain level. Results Patients in the scapular stabilization stretching group increased horizontal adduction 40° (CI95 31, 48°) compared to the non-stabilization stretching group increase of 8° (CI95 0, 17°) over the course of the three treatments (p&lt;0.001). Similarly, the stabilized stretching group increased internal rotation 48° (CI95 26, 69°) compared to the non-stabilized stretching group increase of 26° (CI95 4, 48°) (p=0.001). Pain decreased in the stabilized stretching group by 1.4 points (CI95 -0.4, 3.2) but increased slightly in non-stabilized group by -0.5 points (CI95 -2.3, 1.3) which was not a clinically meaningful change. (p=0.03) Conclusion Stabilized scapular stretching was more effective than non-stabilized stretching at gaining shoulder mobility in patients with shoulder pain. Benefits were immediate and sustained between treatment sessions. Stretching interventions improved range of motion but had limited effect on shoulder pain. Level of Evidence 2

Peripheral sensitization is demonstrated in subacromial pain syndrome, with central sensitization found only in females.

The objective of this study was to explore whether hypersensitivity in patients with subacromial pain syndrome (SPS) manifests purely as localized peripheral sensitization or central sensitization, is influenced by the presence of subacromial pain, and presents similarly in male and female patients. Pressure pain threshold was assessed in both a patient cohort with unilateral SPS and an uninjured matched control group. Control subjects were assessed twice, with a 15 minute rest period between testing, while patients were assessed at baseline and after an almost instantaneous reduction in pain arising from an anesthetic injection in patients. Patients received a subacromial injection consisting of both anesthetics (3 cc of 2% lidocaine and 6 cc 0.5% Marcaine with Epinephrine) and a corticosteroid agent (1 cc DepoMedrol). Patients demonstrated hypersensitivity across the involved shoulder only, providing evidence for peripheral sensitization. There were trends for hypersensitivity across remote joints, however when separated by sex, only female patients demonstrated both peripheral and central sensitization. Immediate pain reduction had no influence on hypersensitivity in the short-term.Clinical Significance: Neuropathic components are likely present in some patients with subacromial pain syndrome, and female patients may be particularly at risk for presenting with neuropathic pain. These findings are applicable towards understanding the heterogeneous etiology underlying subacromial pain syndrome and informing clinical management.

The impact of a patient decision aid on intention to undergo surgery for subacromial pain syndrome: An online randomised controlled trial

ObjectiveTo evaluate the effects of a patient decision aid for people considering shoulder surgery. MethodsParticipants with shoulder pain considering shoulder surgery (n = 425) were recruited online and randomised to (i) a decision aid outlining the benefits and harms of shoulder surgery and non-surgical options (then randomised to a side-by-side vs. top-and-bottom display of options); and (ii) general information about shoulder pain from the NHS. Outcomes included treatment intention (primary), knowledge, attitudes, informed choice, and decisional conflict. Linear and logistic regression models were used to evaluate between-groups differences in outcomes. Results409 participants (96%) had post-intervention data. Mean age was 41.3 years, 44.2% were female. There was no between-group difference in post-intervention treatment intention (MD −0.2, 95% CI: −3.3 to 2.8) and likelihood of intending to have shoulder surgery (OR 0.7, 95% CI: 0.3–1.5). The decision aid slightly improved knowledge (MD 4.4, 95% CI: 0.2–8.6), but not any other secondary outcomes. The display of options did not influence any outcome. ConclusionsIn this online trial, a co-designed patient decision aid had no effect on treatment intention, attitudes, informed choice, and decisional conflict, but a small effect on improving knowledge. Practice implicationsResearch is needed to understand reasons for the lack of anticipated effects. Trial registrationAustralia New Zealand Clinical Trials Registry (ACTRN12621000992808).

ARE CRANIOCERVICAL FLEXION TEST AND THE PECTORALIS MINOR INDEX USEFUL TESTS FOR PATIENTS WITH SUBACROMIAL PAIN SYNDROME?

Cervical disorders and the shortening of the pectoralis minor are advocated to play an important role in patients with subacromial pain syndrome, despite the absence of evidence. This study aimed to compare the deep cervical flexor muscle function and the shortening of the pectoralis minor between patients with subacromial pain syndrome and controls. Secondarily, this study aimed to analyze the relationship of clinical tests with pain and disability among patients. This is a case-control study with 32 patients with subacromial pain syndrome [mean age: 33 ± 6.9 years; sex: 22 (65.6%) men; right dominance: 31 (96.9%)] and 32 controls matched for age, sex, handedness, and affected side. Participants filled the Numerical Pain Rating Scale, the Shoulder Pain and Disability Index; and performed the clinical tests which were compared between patients and controls. Pectoralis minor length of the patient’s group (median = 9.0) was similar to the controls (median = 9.7) (U = 421.5; p = 0.22). The deep neck muscle function presented no statistical difference between patients and controls (?2 = 4.319; p = 0.504). There was no statistically significant correlation between clinical tests and patient self-reported measures. Therefore, deep cervical flexor muscle and the pectoralis minor muscle were not impaired in patients with subacromial pain syndrome and did not show a relationship with self-reported measures.

Weakness in patients with subacromial pain syndrome is local and more pronounced in females

BackgroundSubacromial pain syndrome is the predominant cause of shoulder pain, accounting for approximately half of all shoulder complaints. This population presents with weakness of the involved shoulder. However, there is a gap in our understanding of how pain contributes to this weakness, and whether there are sex related differences. MethodsRegional and global isometric strength was tested at the involved shoulder joint and remote joints (uninvolved shoulder and both knees) in patients with subacromial pain syndrome. Data were collected before and after acute pain reduction with a subacromial injection. FindingsPatients demonstrated weakness at the involved shoulder while remote joints demonstrated normal strength. When compared to healthy controls, male patients were shown to exhibit greater levels of weakness than female patients at the involved shoulder, based on comparisons with sex-matched controls using z-scores. Pain reduction (through an anesthetic injection) had no influence on strength in the short-term. InterpretationWeakness in patients appears to be sex dependent and is not resolved with reduction of pain. This calls into question the assumptions of the physiological causes of this weakness.

Subacromial bursitis and shoulder pain: Exploring the predictors for a negative anaesthetic response

Subacromial bursitis and shoulder pain: Exploring the predictors for a negative anaesthetic response

Accuracy of placement of ultrasound-guided corticosteroid injection for subacromial pain (impingement) syndrome does not influence pain and function: Secondary analysis of a randomised controlled trial.

To investigate whether the accuracy of placement of ultrasound-guided (US-guided) corticosteroid injections for subacromial pain (impingement) syndrome (SAPS) influences pain and function outcomes. This was a secondary analysis of data collected in a previous randomised controlled trial (RCT). Video images of US-guided subacromial corticosteroid injections delivered in the RCT were reviewed to categorise injection accuracy into three groups: definitely/probably not in the subacromial bursa (Group 1); probably in the subacromial bursa (Group 2); and definitely in the subacromial bursa (Group3). The primary outcome was the Shoulder Pain and Disability Index (SPADI) totalscore. Secondary outcomes included SPADI pain and function subscales andparticipants' self-reported global impression of change. Outcomes were compared between the accuracy groups after adjusting for pre-selected baseline characteristics. US-guided injection accuracy data were available for 114 participants: 22 categorised into Group 1, 21 into Group 2 and 71 into Group 3. There were no significant differences in mean total SPADI scores between the three injection accuracy groups at 6weeks (Group 2 vs. 1: 8.22 (95% CI -4.01, 20.50); Group 3 versus 1: -0.57 (95% CI -10.27, 9.13) or 6months (Group 2 vs. 1: 12.38 (95% CI -5.34, 30.10); Group 3 versus 1: 3.10 (95% CI -11.04, 17.23). The accuracy of injection placement in SAPS did not influence pain and function, suggesting that improvements in patients' outcomes using subacromial corticosteroid injections can be achieved without US guidance.

Yi Jin Bang exercise versus usual exercise therapy to treat subacromial pain syndrome: a pilot randomised controlled trial

ABSTRACT To evaluate the effect of Yi Jin Bang (YJB) exercise on pain, disability, flexibility, and muscular endurance in individuals with subacromial pain syndrome (SAPS). Fifty-four adults with SAPS were randomly allocated into either a YJB (n = 18), a usual exercise therapy (UET; n = 18), or a control group (n = 18). YJB and UET interventions involved 10 weeks of home-based exercise training, with four sessions per week. The control group received no treatment. Outcome measures included Shoulder Pain and Disability Index (SPADI), pain at rest and during activity, flexion and abduction range of motion (ROM), back scratch test, and shoulder abduction endurance test. These measures were assessed at baseline, immediately after a single face-to-face session (acute effects), and after 10 weeks of intervention (chronic effects). For acute effects, significant group-by-time interactions were observed for flexion ROM, abduction ROM, and the back scratch test (all p < 0.05). For chronic effects, significant group-by-time interactions were found for pain during activity, the SPADI score, and the back scratch test (all p < 0.05). Home-based YJB exercise is comparable to home-based UET in reducing pain and disability and improving flexibility.

CME-Sonografie 103: Subakromiales (SAI) und subkorakoidales Impingement (SCI)

CME Sonography 103: Subacromial Pain Syndrome (SAPS) and Subcoracoid Impingement (SCI) Abstract. Pain in the shoulder can have its origin in different structures of the shoulder joint or in affected periarticular structures. Therefore, it is important to be able to make a specific diagnosis and identify the exact pathology behind it in order to initiate the most appropriate individually precise treatment. In this review, we discuss possible causes of impingement of the shoulder.

Comparing exercises with and without electromyographic biofeedback in subacromial pain syndrome: A randomized controlled trial

BackgroundDeficits in movement and muscle activation of scapulohumeral joint are related to Subacromial Pain Syndrome. Electromyography biofeedback during exercise may enhance muscle activation and coordination, and consequently improve pain and shoulder function. MethodsThis study compared the effects of an exercise protocol with and without using electromyographic biofeedback on pain, function and movement of the shoulder complex in subjects with Subacromial Pain Syndrome. A total of 24 patients with subacromial pain (mean age = 46.2 + 8.1;18 women) were randomized to either therapeutic exercise or exercise plus biofeedback to the trapezius and serratus muscles. Pain and shoulder function were evaluated as the primary outcome and range of motion, muscle strength, electromyographic activity and scapulohumeral kinematics as secondary outcomes. The subjects underwent eight weeks of intervention and comparisons were made between groups in baseline, at 4 weeks, 8 weeks, and at 4 weeks post intervention. FindingsThere were differences between groups for pain [mean difference = 1.5 (CI 0.3, 3.2) p = 0.01] at 8 weeks in the Exercise group and scapular upward rotation at 60° of arm elevation [mean difference = 13.9 (CI 0.9, 9.3), p = 0.006] in the Biofeedback group. There was no difference for the other variables of scapular kinematics as well as for shoulder function (DASH), muscle strength, range of motion and electromyographic variables. InterpretationThe addition of Biofeedback to the exercise protocol increased upward rotation of the scapula. However, the volunteers who performed only the Exercises had a better response in reducing pain.

Costs of shoulder disorders in Denmark: a nationwide cost-of-illness study investigating 617,334 patients and matched controls.

Shoulder disorders are very common musculoskeletal conditions. Few studies have focused on the costs associated with shoulder disorders, and the economic burden has never been established in a nationwide cost-of-illness study. We aimed to evaluate the healthcare costs and costs of productivity loss (sick leave) and to evaluate if costs were higher for specific subgroups. Using national Danish registers, we identified individuals with shoulder disorders (subacromial pain, stiffness, fracture, or dislocation) diagnosed between 2005 and 2017 and controls matched on age and gender without shoulder disorders. Health care usage, sick leave, and related costs were estimated. During the 13-year inclusion period, 617,334 unique individuals were identified and the incidence rate was 1215 per 100,000 person-years in 2017. The expected additional societal costs were €1.21 billion annually. The mean additional total costs for the 6-year period were €11,334 (11,014-11,654) for individuals aged ≥65 years and €25,771 (25,531-26,012) for individuals aged <65 years. For individuals in the working age, the costs of sick leave accounted for approximately 70% of the total costs. Individuals aged ≥65 years had healthcare costs that were twice as high as individuals aged <65 years. Additionally, the 20% of cases accruing the highest costs accounted for 66% of the total costs. In conclusion, incidence rates of shoulder disorders were high and costs of sick leave accounted for a large proportion of total costs associated with illness in working age people. Furthermore, a minority of patients accounted for a substantial share of the total costs.

Does Scapular Dyskinesis Really Matter? A Narrative Review

Subacromial pain disorder being the common presentation of shoulder pain is one among the prevalent musculoskeletal disorders. Variations in scapular kinematics are often associated with different conditions of shoulder pain. Increased scapular internal rotation decreased scapular upward rotation and decreased posterior tilt are common changes. Its still unclear whether shoulder pain is caused by or caused by altered scapular motion. This study aims to determine the certainties and uncertainties pertaining to Scapular Dyskinesis. A database search was conducted in PubMed MEDLINE SCOPUS and Google Scholar for studies including Scapular Dyskinesis as a condition as well as functional adaptation. Scapular Dyskinesis has been linked to an increased risk of shoulder pain in athletes and its possible that this is also true in the general population. Its been discovered in overhead athletes as a variation. A lack of definitive reliability exists in the measures used to determine Scapular location. There was also no evidence of a cause-and-effect relationship between Scapular Dyskinesis and shoulder pathology in studies. In terms of Scapular Dyskinesis there are certainties and uncertainties. There have been gaps in the cause-effect relationship of Scapular Dyskinesis and shoulder pathology and also the evaluation of scapula role in dynamic activity. As a result more research is necessary to understand the significance of Scapular Dyskinesis and its function in both healthy people and people with shoulder dysfunctions.nbsp

Home training with or without joint mobilization compared to no treatment: a randomized controlled trial.

[Purpose] To investigate if joint mobilization in patients with subacromial pain syndrome has additional benefits to a home training program on shoulder function and pain, and to compare home training to no physical therapy. [Participants and Methods] Eighty-nine primary care patients (mean age 45 years) with subacromial pain syndrome during an average of 23 weeks. Home training was performed twice a day during a 12 week period. One of the intervention groups received add-on shoulder joint mobilization to the home training. A third group did not receive any physical therapy. Constant-Murley score, pain and active range of motion was evaluated at baseline, 6 weeks, 12 weeks and 6 months. [Results] The total Constant-Murley score revealed no significant differences between groups at any time point. All groups improved over time. The add-on joint mobilization group reached clinical important change at 12 weeks. The subscale pain showed that both intervention groups reported less pain after 12 weeks compared to the reference group. [Conclusion] Home training is not superior to no treatment evaluated with the total Constant-Murley score. However, home training with or without add-on joint mobilization may decrease pain compared to no treatment.
