Effectiveness of a joint mobilizations protocol for shoulder subacromial pain syndrome: A pilot study.

BACKGROUND: Subacromial pain syndrome (SPS) is the most frequent shoulder pathology. The aims of this prospective randomized study were to evaluate the effects of some specific shoulder joint mobilizations ("spin correction"), and the effectiveness of a rehabilitation program, named Shoulder Global Concept, in SPS patients. METHODS: 45 patients with SPS were randomly assigned to two groups, to benefit from a different first session of mobilizations: the experimental group received all specific mobilizations, while the control group received the same program but without the spin correction mobilizations. The second session was identical for both groups, with all specific mobilizations. Before and after the first two sessions, range of motion (ROM) in flexion, abduction, external and internal rotations, pain and functional status with Constant score and Quick Dash were evaluated. Evaluation was repeated with 24 patients after 11 rehabilitation sessions. Rehabilitation with Shoulder Global Concept included 13 mobilizations aiming at improving the ROM with passive and active-assisted mobilizations, static stretching, and muscle strengthening. RESULTS: All ROM were improved at the end of the first session for both groups, but significantly more in the experimental group for glenohumeral (GH) abduction and external rotation (p < 0.05). Functional scores, pain and strength were significantly improved after 11 rehabilitation sessions with the Shoulder Global Concept. CONCLUSION: This manual therapy method was able to improve shoulder mobility in one session. The additional joint mobilizations (spin correction) specifically increased GH abduction and external rotation. Rehabilitation of SPS with Shoulder Global Concept allowed to improve functional capacity and decrease pain.

Treatment of shoulder impingement syndrome: a survey of physical therapists in Saudi Arabia.

OBJECTIVE: Shoulder impingement syndrome (SIS) is one of the most frequent causes of shoulder pain. Evidence supported the use of conservative treatment for SIS. Clinical practice guidelines (CPGs) indicated that physical therapy interventions, including therapeutic exercises, manual therapy, patient education, and advice, were recommended for the treatment of SIS. This study's purpose was to investigate physical therapists' adherence to the CPGs for treating SIS. SUBJECTS AND METHODS: Physical therapists in Saudi Arabia were invited to participate in an online survey via the Saudi Physical Therapy Association between May and December 2022. The developed online survey consisted of 36 questions, divided into five sections: eligibility, demographics, clinical practice regarding the treatment of SIS, barriers, and facilitators for the use of CPGs. Descriptive and logistic regression analysis were employed to analyze study data. RESULTS: A total of 313 physical therapists completed the entire survey. In general, physical therapists were aligned with CPGs. Physical therapists advised their patients, utilized therapeutic exercises and manual therapy techniques, and used electrotherapy modalities despite being not recommended. Key challenges indicated by physical therapists for the use of CPGs include low patient adherence to therapists' instructions, lack of adequate knowledge, and limited clinical time. CONCLUSIONS: Overall, physical therapists in Saudi Arabia followed the CPGs for treating SIS. Therapeutic exercises combined with manual therapy were the most common treatment options. However, further research should consider exploring adherence to such guidelines over time.

Patient Preferences and Their Effects on Rehabilitation Outcomes: A Secondary Analysis of a Randomized Controlled Trial.

OBJECTIVE: To assess the effect of aligning patients' preferences with specific rehabilitation delivery modes on rehabilitation outcomes. DESIGN: A secondary analysis of a randomized controlled trial. METHODS: The study cohort comprised 208 patients referred for physiotherapy rehabilitation after nonsurgical or surgical interventions for rotator cuff injury, shoulder impingement, or acromioclavicular osteoarthritis. Participants were randomly assigned to 1 of 3 rehabilitation modalities: (1) group-based exercise, (2) individual exercise, or (3) home exercise. In this study, participants were categorized into 2 groups: "matched preference" and "unmatched preference." The primary outcome measure was change in function, measured with the shortened Disabilities of the Arm, Shoulder and Hand (QuickDASH). Secondary outcome measures were change in pain, assessed using the Numeric Rating Scale (NRS), mental well-being measured with the World Health Organization Five Well-Being Index (WHO-5), health-related quality of life assessed using the EuroQol-5 Domain questionnaire (EQ-5D), fear avoidance assessed using the Örebro Musculoskeletal Pain Questionnaire (ÖMPQ), and overall treatment satisfaction. Outcomes were assessed at 3 and 6 months. RESULTS: The primary outcome measure, QuickDASH, showed no significant differences between groups at either 3 months (-3.0 [-8.2 to 2.3]) or 6 months (0.5 [-5.7 to 6.7]). Additionally, no significant differences were observed in the secondary outcome measures. CONCLUSION: Matching patients' preferences for specific rehabilitation delivery modes did not seem to effect rehabilitation outcomes. J Orthop Sports Phys Ther 2024;54(6):1-9.

Effect of Exergame on Pain, Function, and Quality of Life in Shoulder Impingement Syndrome: A Prospective Randomized Controlled Study.

Objective: This study aimed to investigate the effect of a virtual reality (VR)-mediated gamified rehabilitation program added to a home exercise program on pain, functionality, and quality of life in shoulder impingement syndrome. Methods: Forty-eight participants with shoulder impingement syndrome were included in this prospective, randomized, single-blind study between January and July 2022. The participants were randomized into two groups: the VR group (n = 24) and the control group (n = 24). All participants were given a home exercise program for 3 weeks, with five sessions per week. The participants in the VR group received 15 sessions (45 minutes each session) of a gamified shoulder exercise program with an immersive VR headset, while those in the control group received 15 sessions (45 minutes each session) of supervised therapeutic exercises. The participants were evaluated and compared before and after treatment using the 36-item Short Form Survey (SF-36), range-of-motion (ROM) measurements, the Visual Analog Scale (VAS), and the Shoulder Pain and Disability Scale (SPADI). Results: At the baseline assessment, the two groups were homogenous regarding demographic and clinical parameters. The post-treatment shoulder extension and adduction ROM was significantly greater in the VR group and the post-treatment pain subscales for SPADI and SF-36 were significantly lower in the VR group. Conclusion: In individuals with shoulder impingement syndrome, a VR-mediated gamified exercise program added to a home exercise program increased shoulder ROM and reduced pain scores. Further clinical studies are needed to prove the long-term efficacy of the addition of VR-mediated gamified exercises to the treatment of this condition in clinical settings.

Effectiveness of Pulse Electromagnetic Field Therapy in Patients With Subacromial Impingement Syndrome: A Double-Blind Randomized Sham Controlled Study.

OBJECTIVES: To evaluate the 3-month effects of pulsed electromagnetic field therapy (PEMF) in the treatment of subacromial impingement syndrome (SIS). DESIGN: Planned analysis of a randomized controlled trial with 4- and 12-week follow-ups. SETTING: Physical medicine and rehabilitation clinic, treatment unit. PARTICIPANTS: Of the 250 individuals screened for eligibility, participants with a diagnosis of SIS (N=80) were randomized to intervention or control groups. INTERVENTION: The first group received PEMF + exercise and the second group received sham PEMF + exercise 5 days a week for a total of 20 sessions. MAIN OUTCOME MEASURES: Visual Analog Scale (VAS), Constant Murley Score (CMS), Shoulder Pain and Disability Index (SPADI), Short Form-36 (SF-36) Quality of Life Questionnaire, and shoulder muscle strength measurement with an isokinetic dynamometer. Evaluations were performed before treatment (T0), after treatment (T1), and 12th week (T2). RESULTS: Evaluation at T1 and T2 showed improvement in most parameters in both groups compared with baseline. In the comparison between the 2 groups at T1 and T2, more improvement was found in the PEMF group in most parameters. CONCLUSIONS: In our study, PEMF was found to be superior to sham PEMF in terms of pain, ROM, functionality, and quality of life at the first and third months.

Comparative Analysis of Muscle Synergy between Patients with Shoulder Impingement Syndrome and Healthy Controls: A Preliminary Study.

Shoulder impingement syndrome can be caused by a muscle imbalance around the shoulder joint. It would be beneficial for therapy to implement rehabilitation exercises based on intermuscular coordination in order to achieve muscle balance. This study presents the muscle synergy characteristics of patients with shoulder impingement syndrome, which can be used to develop rehabilitation exercises. During pick and place task, the muscle synergy obtained from eight shoulder muscles in patients and healthy subjects was compared. The experimental results revealed that patients have low contributed muscle synergy structures for the serratus anterior and infraspinatus.Clinical relevance- This proposes that patients with shoulder impingement syndrome may have abnormal muscle synergy structure which can be used for assessment.

Supervised Training Compared With No Training or Self-training in Patients With Subacromial Pain Syndrome: A Systematic Review and Meta-analysis.

OBJECTIVE: To study the effects of supervised training in adults with subacromial pain syndrome. DATA SOURCES: Embase, MEDLINE, Cochrane Library, Cumulative Index to Nursing and Allied Health, and Physiotherapy Evidence Database were searched from inception to March 2020. STUDY SELECTION: Independent reviewers selected randomized controlled trials comparing supervised training with (1) no training or (2) self-training in adults with subacromial pain syndrome lasting for at least 1 month. Critical outcomes were shoulder pain, function, and patient-perceived effect. Important outcomes included other potential benefits and adverse events at 3-month follow-up. DATA EXTRACTION: Two independent reviewers extracted data for the meta-analysis. Risk of bias was assessed using the Cochrane Risk of Bias tool 1, and certainty of evidence was evaluated using the Grades of Recommendation Assessment, Development, and Evaluation (GRADE). DATA SYNTHESIS: Ten studies (n=597, 43% female) were included. Supervised training resulted in larger improvements than no training on pain (at rest: n=286; mean difference [MD], 1.68; 95% confidence interval [CI], 0.31-3.06 on 0-10 scale; during movement: n=353; MD, 1.84; 95% CI,0.91-2.76), function (n=396; standardized MD, 0.30; 95% CI, 0.07-0.52), and patient-perceived effect (n=118; risk ratio, 1.43; 95% CI, 0.87-2.34). Supervised training had potential benefits regarding quality of life, return to work, dropout, and training adherence, albeit more patients reported mild, transient pain after training. Supervised training and self-training showed equal improvements on pain (n=44) and function (n=76), with no data describing patient-perceived effect. Certainty of evidence was low for critical outcomes and low-moderate for other outcomes. CONCLUSIONS: Supervised training might be superior to no training and equally effective as self-training on critical and important outcomes. Based on low-moderate certainty of evidence, these findings support a weak recommendation for supervised training in adults with subacromial pain syndrome.

Feedback improves the scapular-focused treatment effects in patients with shoulder impingement syndrome.

PURPOSE: This study aimed to evaluate the effects of scapular-focused treatment with (SFTF) and without (SFT) feedback on pain, function, and scapular kinematics in patients with Shoulder Impingement Syndrome (SIS). METHODS: Seventy-five males and females with SIS were randomly assigned into SFTF (n = 25), SFT (n = 25) and control (n = 25) groups. The primary outcome was pain, assessed by Visual Analog Scale (VAS). The secondary outcomes were function and scapular kinematics, assessed by DASH Questionnaire and a 3-D motion capture, respectively. All outcomes were measured at the baseline and after the 8-week interventions. RESULTS: A post hoc analysis performed to show significant differences between groups after the 8-week interventions. For pain, there were significant differences between SFTF vs. SFT (ES (95% CI) = - 0.3(- 0.4 to - 0.1); P = 0.04), SFTF vs. control (ES (95% CI) = 1.3(0.7-1.9); P = 0.01). For DASH, also, there were significant differences between SFTF vs. SFT (ES (95% CI) = 1.8(1.1-2.4); P = 0.03), SFTF vs. control (ES (95% CI) = 4.4(3.3-5.4); P = 0.01), and SFT vs. control (ES (95% CI) = 2.6(1.8-3.4); P = 0.01). For scapular internal rotation (the sagittal or scapular planes), scapular upward rotation, and the scapular tilt, however, there were no differences between SFTF vs. SFT. CONCLUSION: Based on the study results, a rehabilitation program integrated with verbal feedbacks is effective to relieve pain, and improve function and scapular kinematics in patients with SIS. Adding feedback to an exercise therapy could clinically enhance outcomes in patients with SIS. LEVEL OF EVIDENCE: Level II. TRIAL REGISTRATION: This study was prospectively registered at UMIN-CTR website, and the unique trail number is UMIN000036399.

Efficacy of low-level laser therapy combined with exercise for subacromial impingement syndrome: A randomised controlled trial.

OBJECTIVE: To investigate the effect of low-level laser therapy (LLLT) combined with exercise on shoulder pain and disability in patients with subacromial impingement syndrome (SIS). DESIGN: Randomised controlled trial. SETTING: Pontifical Catholic University. SUBJECTS: We enrolled 120 subacromial impingement syndrome patients. INTERVENTION: Groups I (n = 42), II (n = 42) and III (n = 36) were treated with Low-level laser therapy and exercise, exercise only and Low-level laser therapy only, respectively. Interventions were conducted three times a week for 8 weeks. MAIN OUTCOME MEASURES: The primary outcome was the change in shoulder pain and disability index (SPADI). Secondary outcomes included changes in the numeric pain rating scale and medication intake. RESULTS: Average ages of patients in groups I, II and III were 51.9 ± 8.7 years, 56.0 ± 10.4 years and 54.2 ± 7.1 years, respectively. Pain scores at baseline (P = 0.829), 2 months (P = 0.057) and 3 months follow-ups (p = 0.004) were 6.8 (4.7-7.7), 0.2 (0.0-0.5) and 0.3 (0.0-1.0) for group I; 6.6 (5.7-8.0), 0.5 (0.2-2.0) and 0.2 (0.0-3.3) for group II; and 6.5 (5.1-7.4), 2.4 (0.1-6.7) and 4.0 (2.0-5.0) for group III, respectively. SPADI scores at baseline (P = 0.029), 2 months (P < 0.001) and 3 months follow-ups (P = 0.001) were 60.8 (37.7-70.8), 3.8 (0.0-10.8) and 2.3 (0.8-10.8) for group I; 61.5 (41.5-71.5), 9.2 (3.8-29.2) and 14.2 (1.5-38.0) for the group II; and 73.3 (59.2-80.8), 34.2 (16.9-54.6) and 33.1 (22.3-49.2) for the group III, respectively. CONCLUSION: Low-level laser therapy combined with exercises reduce pain intensity, improve shoulder function and reduces pain intensity and medication intake over 3 months. CLINICAL TRIAL REGISTRATION NUMBER: NCT02725749.

Comparing the effects of no intervention with therapeutic exercise, and exercise with additional Kinesio tape in patients with shoulder impingement syndrome. A three-arm randomized controlled trial.

OBJECTIVE: To investigate if adding Kinesio tape to therapeutic exercise is an effective treatment to improve clinical outcomes compared to therapeutic exercise alone and no intervention, in patients with shoulder impingement syndrome. DESIGN: Three-arm randomized controlled trial. SETTING: Outpatient setting. SUBJECTS: One hundred and twenty patients (mean (SD): age 37.8 (5.4)) with shoulder impingement syndrome. INTERVENTION: Patients were randomly assigned to eight-weeks therapeutic exercise alone, therapeutic exercise with Kinesio tape, and control group. MAIN MEASURES: Pain was measured with a numerical rating scale and disability and scapular kinematics were measured with a relative questionnaire and motion analysis software respectively, at baseline and after eight-weeks intervention. RESULTS: There was significant differences in therapeutic exercise with Kinesio tape group vs. therapeutic exercise alone and control group respectively for pain (d = -0.34, P = 0.042; and d = -1.53, P = 0.001), disability (d = -0.46, P = 0.024; and d = -2.18, P = 0.001), scapular upward rotation at sagittal plane (d = 0.33, P = 0.033; and d = 0.68, P = 0.001), scapular plane (d = 0.18, P = 0.045; and d = 0.43, P = 0.001), scapular tilt at sagittal plane (d = 0.55, P = 0.043; and d = 1.39, P = 0.001), and scapular plane (d = 0.29, P = 0.034; and d = 0.58, P = 0.001). Therapeutic exercise alone was superior over control group in all significant outcomes (P < 0.05). CONCLUSION: Although therapeutic exercises alone showed positive effect on clinical outcomes, adding Kinesio tape to therapeutic exercises had more significant effects with larger effect sizes. Adding Kinesio tape to therapeutic exercise may be of some assistance to clinicians in improving clinical outcomes in patients with shoulder impingement syndrome.

Subacromial decompression versus diagnostic arthroscopy for shoulder impingement: a 5-year follow-up of a randomised, placebo surgery controlled clinical trial.

OBJECTIVES: To assess the long-term efficacy of arthroscopic subacromial decompression (ASD) by comparing it with diagnostic arthroscopy (primary comparison), a placebo surgical intervention, and with a non-operative alternative, exercise therapy (secondary comparison). METHODS: We conducted a multicentre, three group, randomised, controlled superiority trial. We included 210 patients aged 35-65 years, who had symptoms consistent with shoulder impingement syndrome for more than 3 months. 175 participants (83%) completed the 5 years follow-up. Patient enrolment began on 1 February 2005 and the 5-year follow-up was completed by 10 October 2018. The two primary outcomes were shoulder pain at rest and on arm activity measured with Visual Analogue Scale (VAS). Minimally important difference (MID) was set at 15. We used a mixed-model repeated measurements analysis of variance with participant as a random factor, the baseline value as a covariate and assuming a covariance structure with compound symmetry. RESULTS: In the primary intention to treat analysis (ASD vs diagnostic arthroscopy), there were no between-group differences that exceeded the MID for the primary outcomes at 5 years: the mean difference between groups (ASD minus diagnostic arthroscopy) in pain VAS were -2.0 (95% CI -8.5 to 4.6; p=0.56) at rest and -8.0 (-17.3 to 1.3; p=0.093) on arm activity. There were no between-group differences in the secondary outcomes or adverse events that exceeded the MID. In our secondary comparison (ASD vs exercise therapy), the mean differences between groups (ASD minus exercise therapy) in pain VAS were 1.0 (-5.6 to 7.6; p=0.77) at rest and -3.9 (-12.8 to 5.1; p=0.40) on arm activity. There were no significant between-group differences for the secondary outcomes or adverse events. CONCLUSIONS: ASD provided no benefit over diagnostic arthroscopy (or exercise therapy) at 5 years for patients with shoulder impingement syndrome.

Tight shoulders: A clinical, kinematic and strength comparison of symptomatic and asymptomatic male overhead athletes before and after stretching.

A tightness of the posterior structures of the throwing shoulder has been hypothesised to be associated with injuries and pain because of alterations of the scapular kinematics and muscular imbalances. The aims of this study were to identify the clinical and biomechanical profile of symptomatic and asymptomatic overhead athletes with a tight shoulder and to evaluate the efficiency of a self-applied stretching program. Twenty male overhead athletes were recruited. Half of them reported a painful shoulder at the beginning of the study. For four weeks, the volunteers performed daily stretching exercises. Before and after the stretching program, gleno-humeral mobility, scapular kinematics, rotator muscles strength and pain were evaluated. Before stretching, the main difference between the groups was more impingement syndrome and rotator cuff tendon lesion positive tests in the symptomatic group (p < 0.027, effect size = 0.51). After the program, pain reported by the symptomatic volunteers was reduced by approximately 40% and the gleno-humeral internal rotation bilateral difference was significantly reduced by 77.6% (p < 0.009, effect size = 0.84). In the symptomatic group, the scapula at rest was significantly more posteriorly tilted (p = 0.027, effect size = 0.69) after the stretching; a position that has been shown to limit the risk of impingement. The absence of significant differences of the profiles of the symptomatic and asymptomatic overhead athletes before stretching may indicate that the initiation of early prevention programs, including self-applied stretching, should not rely solely on biomechanical and clinical parameters and might be recommended to all players with a tight shoulder.

Efficacy of throwing exercise with TheraBand in male volleyball players with shoulder internal rotation deficit: a randomized controlled trial.

BACKGROUND: The Glenohumeral internal-rotation deficit (GIRD) is related to the altered eccentric external-rotator (ER), the concentric internal-rotator (IR), muscle strength, and the ER: IR ratio. GIRD has been documented as a risk factor for shoulder injuries. However, few studies have investigated the effect of an exercise training on these parameters in athletes with GIRD. Therefore, the purpose of this study was to evaluate the effects of an 8-week throwing exercise with a TheraBand for retraining the rotator cuff on Electromyography (EMG) activity of selected muscles, rotator cuff muscle strength, the glenohumeral (GH) joint IR range of motion (ROM) and GH joint position sense in asymptomatic male volleyball players with GIRD. METHODS: Sixty male volleyball players with GIRD were randomized into either a training group or a control group. The experimental group underwent an 8-week throwing exercise with a TheraBand including 5 sessions of stretching and 3 sessions of strengthening exercises per week. The control group received an active self-exercise program. EMG (onset time and muscle activation), shoulder range of motion (ROMs), strength and GH joint position sense were all assessed pre and post trainings. RESULTS: There were statistically significant within-group differences in the EMG activity of the anterior deltoid (p = 0.005), middle deltoid (p = 0.007), posterior deltoid (p = 0.004), infraspinatus (p = 0.001) and supraspinatus (p = 0.001) muscles, IR ROM (p = 0.001), rotator cuff muscle strength ratio (p = 0.001), and GH joint position sense (p = 0.033) in the experimental group. A 2 × 2 analysis of variance with a mixed model design and independent and paired t-tests were used for statistical analysis. CONCLUSIONS: Throwing exercise with a TheraBand improved shoulder muscle activation, IR ROM, rotator cuff muscle strength ratio and GH joint position sense in participants with GIRD. These findings may improve the treatment of GIRD in a clinical setting. Although the results are significant, further studies should follow up the long-term effects of the Throwing exercise with a TheraBand on GIRD.

Ultrasound-guided versus blind subacromial corticosteroid and local anesthetic injection in the treatment of subacromial impingement syndrome: A randomized study of efficacy.

OBJECTIVES: This study aims to compare the effects of ultrasound (US)-guided and blind subacromial corticosteroid and local anesthetic (LA) injection in the treatment of subacromial impingement syndrome (SIS) on shoulder pain, range of motion (ROM), and functionality. PATIENTS AND METHODS: The prospective study was conducted between 01 February 2017 and 31 May 2017. A total of 29 patients with clinical findings and magnetic resonance imaging (MRI) consistent with SIS were randomized into two groups: 14 patients received US-guided subacromial corticosteroid and LA injection and 15 patients received a blind subacromial corticosteroid and LA injection. Patients were evaluated before and one month after treatment. One patient was lost to follow up. The primary outcome measure was a visual analog scale (VAS) for shoulder pain. Secondary outcomes were active shoulder ROM in flexion and abduction, the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and the modified Constant-Murley Score (CMS). RESULTS: Twenty-eight patients (11 males, 17 females; mean age 39.5 in the US guided group and 42.5 in the blind group; range 20 to 64 years in both groups) completed the study. There was a significant improvement in VAS for shoulder pain, active ROM, DASH questionnaire score and modified CMS in both groups four weeks after treatment (p<0.05). There was no between-group difference in VAS, ROM or DASH questionnaire scores. Following treatment, the modified CMS in the US-guided injection group was higher than in the blind injection group (p=0.02). However, when the mean change in modified CMS in the US-guided injection group was compared to that of the blind injection group, the difference was insignificant (p=0.23). CONCLUSION: Both US-guided and blind subacromial steroid injection improve shoulder pain, ROM, and functionality in SIS; one treatment option was not found to be superior to the other. Therefore, blind injection can be performed in clinical settings where US is not available. Equally, blind injection can also be performed in patients who have a definite diagnosis of SIS based on clinical and MRI findings.

Effect of supervised physiotherapy versus home exercise program in patients with subacromial impingement syndrome: A systematic review and meta-analysis.

OBJECTIVE: To determine whether supervised physiotherapy is more effective for functional improvement and pain relief than a home exercise program in subjects with subacromial impingement syndrome. DESIGN: Systematic review and meta-analysis of randomized clinical trials. METHODS: An electronic search was performed in Medline, Central, Embase, PEDro, Lilacs, Cinahl, SPORTDiscus, and Web of Science databases. The eligibility criteria for selecting studies included randomized clinical trials that compared supervised physiotherapy versus home exercise program, in the shoulder function, pain, and range of motion in subjects older than 18 years of age with a medical diagnosis of subacromial impingement syndrome treated conservatively. RESULTS: Seven clinical trials met the eligibility criteria, and for the quantitative synthesis, four studies were included. The standardized mean difference for shoulder function was -0.14 points (95% CI: -1.04 to 0.76; p = 0.760), mean difference 0.21 cm (95% CI: -1.36 to 1.78; p = 0.790) for pain, and mean difference 0.62° (95% CI: -7.15 to 8.38; p = 0.880) for range of motion of flexion. CONCLUSION: Supervised physical therapy and home-based progressive shoulder strengthening and stretching exercises for the rotator cuff and scapular muscles are equally effective in patients with subacromial impingement syndrome treated conservatively. TRIAL REGISTRATION NUMBER: CRD42018086348.

[Influence of Patients' Profession on Therapeutical Outcome of Patients with Primary Extrinsic Shoulder Impingement]. / Einfluss der beruflichen Tätigkeit auf den Therapieerfolg von Patienten mit primär extrinsischem Impingement der Schulter.

PURPOSE: Shoulder complaints are an important reason for inability to work. There are few considerations that link the effect of kind of therapy with ability to work in connection with kind of employment. This prospective, comparative clinical follow-up study examines the influence of occupational activity with conservative and operative therapy on the outcome of therapy in terms of function, pain and ability to work. METHODS: In this study, 97 patients (women: n=22, men: n=75, mean age: 43.1±10.1 years) with a primary extrinsic shoulder impingement syndrome were included. Patients were divided into blue and white collar workers. Further on the subgroups of conservative and operative therapy were considered. Either a sole conservative therapy or an operative therapy with physiotherapeutic follow-up treatment took place. The conservative therapy was carried out as a structured re-coordination of muscles of the shoulder girdle under supervision of a physiotherapist. In the surgical cohorts an arthroscopic subacromial decompression was performed. Follow-up examinations were passed 3, 6 and 12 months after starting the intervention. Function (Constant Score), pain (NRS) and the duration of inability to work were assessed. The statistical analysis was performed using mixed-design ANOVA to calculate main effect and interactions (therapy*kind of employment*time) adjusted with age, sex and body mass index. RESULTS: There was no statistically significant difference in terms of function and pain between blue and white collar workers. Office workers showed a significantly longer inability to work 3 months after surgical treatment compared with conservative treatment (7.3±0.8 weeks vs. 0.5±7.3 weeks; p<0.001). Further the group of white collars with operative therapy was significantly longer inable to work than the group of blue collar workers after operative therapy 3 months after surgical treatment (3.0±1.1 weeks vs. 7.3±0.8 weeks; p=0.002). CONCLUSION: On the one hand, working in an office could be seen as a negative predictor for durance of inability to work. On the other hand, surgical treatment itself was a negative predictor for the durance of inability to work. Furthermore, no difference between conservative and surgical therapy could be observed in function and pain one year after starting the treatment.

[Health-related quality of life in patients diagnosed with subacromial syndrome in the Talavera Integrated Area]. / Calidad de vida relacionada con la salud en los pacientes diagnosticados de síndrome subacromial en el Área Integrada de Talavera.

OBJECTIVE: There is a high prevalence of subacromial syndrome among patients with shoulder pathology, where the pain and tendency to chronification are some of its most important characteristics. This is why it is necessary to objectively interact with the quality of life of the subject. The main goal was to determine if there are differences between subacromial patients and asymptomatic patients regarding quality of life. METHODS: Transversal study carried out in the Talavera Integrated Area during the months of November 2016 to March2017. Participated a total of 92 subjects, 46 were symptomatic mating by age and sex with an asymptomatic sample and without joint pathology of the same size and health area. In both cases, the EQ-5D questionnaire was administered. The prevalence was calculated from the waiting list of traumatology physiotherapy in the year 2015. The SPSS statistical program was used, applying the T-test and the chi-square. RESULTS: The EQ-5D questionnaire obtained a standardized mean of 0.70 in the subacromial syndrome and 0.85 in the asymptomatic population (P=0.0001). The prevalence of impingement subacromial within shoulder pathology was 39.19%. CONCLUSIONS: Subacromial syndrome has a high prevalence within the shoulder pathology in the Rehabilitation Service and significantly interferes in the quality of life related to the health of the subject.

OBJETIVO: Existe una alta prevalencia del síndrome subacromial dentro de los pacientes con patología de hombro, en el cual el dolor y la tendencia a la cronificación son alguna de sus características más importantes. Por ello es necesario objetivar su interacción con la calidad de vida del sujeto. El objetivo principal del estudio fue determinar si existían diferencias en la calidad de vida entre sujetos con síndrome subacromial y asintomáticos. METODOS: Se realizó un estudio transversal en el Área Integrada de Talavera de la Reina (Toledo), durante los meses de noviembre de 2016 a marzo de 2017. Participaron un total de 92 sujetos, de los que 46 eran sintomáticos, apareándose por edad y sexo con una muestra asintomática y sin patología articular del mismo tamaño y área de salud. En ambos casos se les administró el cuestionario EQ-5D. La prevalencia se calculó a partir de la lista de espera de fisioterapia traumatológica del año 2015. Se utilizó el programa estadístico SPSS, empleándose la prueba T y la chi-cuadrado. RESULTADOS: El cuestionario EQ-5D obtuvo una media estandarizada de 0,70 en el síndrome subacromial y de 0,85 en la población asintomática (p=0,0001). La prevalencia del impingement subacromial dentro de la patología de hombro fue del 39,19%. CONCLUSIONES: El síndrome subacromial tiene una alta prevalencia dentro de la patología de hombro en el Servicio de Rehabilitación e interfiere significativamente en la calidad de vida relacionada con la salud del sujeto.

Effects of eccentric exercise in patients with subacromial impingement syndrome: a systematic review and meta-analysis.

BACKGROUND: Subacromial impingement syndrome is a common problem in primary healthcare. It often include tendinopathy. While exercise therapy is effective for this condition, it is not clear which type of exercise is the most effective. Eccentric exercises has proven effective for treating similar tendinopathies in the lower extremities. The aim of this systematic review was therefore to investigate the effects of eccentric exercise on pain and function in patients with subacromial impingement syndrome compared with other exercise regimens or interventions. A secondary aim was to describe the included components of the various eccentric exercise regimens that have been studied. METHODS: Systematic searches of PubMed, Cochrane Library and PEDro by two independent authors. Included studies were assessed using the PEDro scale for quality and the Cochrane scale for clinical relevance by two independent authors. Data were combined in meta-analyses. GRADE was applied to assess the certainty of evidence. RESULTS: Sixty-eight records were identified. Seven studies (eight articles) were included, six were meta-analysed (n = 281). Included studies were of moderate quality (median PEDro score 7, range 5-8). Post-treatment pain was significantly lower after eccentric exercise compared with other exercise: MD -12.3 (95% CI - 17.8 to - 6.8, I2 = 7%, p < 0.001), but this difference was not clinically important. Eccentric exercise provided no significant post-treatment improvement in function compared with other exercise: SMD -0.10 (95% CI - 0.79 to 0.58, I2 = 85%, p = 0.76). Painful eccentric exercise showed no significant difference compared to pain-free eccentric exercise. Eccentric training regimes showed both similarities and diversity. Intervention duration of 6-8 weeks was almost as effective as 12 weeks. CONCLUSIONS: Evidence of low certainty suggests that eccentric exercise may provide a small but likely not clinically important reduction in pain compared with other types of exercise in patients with subacromial impingement syndrome. It is uncertain whether eccentric exercise improves function more than other types of exercise (very low certainty of evidence). Methodological limitations of existing studies make these findings susceptible to change in the future. TRIAL REGISTRATION: PROSPERO CRD42019126917 , date of registration: 29-03-2019.

A RGBD-Based Interactive System for Gaming-Driven Rehabilitation of Upper Limbs.

Current physiotherapy services may not be effective or suitable for certain patients due to lack of motivation, poor adherence to exercises, insufficient supervision and feedback or, in the worst case, refusal to continue with the rehabilitation plan. This paper introduces a novel approach for rehabilitation of upper limbs through KineActiv, a platform based on Microsoft Kinect v2 and developed in Unity Engine. KineActiv proposes exergames to encourage patients to perform rehabilitation exercises prescribed by a specialist, controls the patient's performance, and corrects execution errors on the fly. KineActiv comprises a web platform where the physiotherapist can review session results, monitor patient health, and adjust rehabilitation routines. We recruited 10 patients for assessing the system usability as well as the system performance. Results show that KineActiv is a usable, enjoyable and reliable system, that does not cause any negative feelings.

Trapezius muscle activation levels and ratios during scapular retraction exercises: A comparative study between patients with subacromial impingement syndrome and healthy controls.

BACKGROUND: Little is known about trapezius muscle activities during scapular retraction exercises in patients with subacromial impingement syndrome. The aim of this study was to compare upper trapezius, middle trapezius and lower trapezius muscle activity and upper/middle and upper/lower trapezius ratios between patients with subacromial impingement syndrome and healthy individuals during six scapular retraction exercises. METHODS: Twenty-two patients with subacromial impingement syndrome and 22 healthy individuals participated. Upper, middle, and lower trapezius activities were measured by surface electromyography, while the participants performed six scapular retraction exercises at different shoulder abduction angles in a standing position. Upper/middle and upper/lower trapezius ratios were also calculated. Repeated-measures analyses of variance were performed to determine whether muscle activation levels and ratios differed between groups during exercises. FINDINGS: There was no significant exercise × group interactions for upper, middle, and lower trapezius activation levels and upper/middle and upper/lower trapezius ratios (P > .05). A main effect for the exercise was observed for the upper/middle and upper/lower trapezius ratios (P < .05). INTERPRETATION: Compared to healthy individuals, patients with subacromial impingement syndrome did not exhibit different upper, middle, and lower trapezius activity and had similar upper/middle and upper/lower trapezius ratios during the various scapular retraction exercises. Therefore, scapular retraction exercises with various shoulder abduction could be safely offered for the patients with subacromial impingement syndrome since it does not lead to abnormal compensatory trapezius muscle activity. If the goal is to minimize upper/middle and upper/lower trapezius ratios, the scapular retraction exercises at 0° shoulder abduction may be used in early stage of shoulder rehabilitation.
