Abstract
Platelet-rich blood derivatives are being nowadays increasingly used in the treatment of tendon-related pathologies as a rich source of growth factors. We sought to ascertain if local application of platelet lysate (PL) to augment rotator cuff repair ameliorates patient outcomes compared to ketorolac tromethamine treated group. A total of forty patients, with clinical diagnosis of Rotator Cuff Tendinopathy were randomized to receive sub acromial injections of PL every week for a total of 3 injections and two injection of ketorolac tromethamine once every two weeks. Subjective assessments included VAS, SPADI and shoulder range of motion were assessed at baseline and at 1 and 6 months after injection. Taking both control and PL groups, it was vividly seen that the outcomes were identical at the initial state, as well as the short-term one; whereas, when considering the 6-month period, there is a seemingly remarkable superiority in PL group in all parameters.

Grandizio LC, Choe LJ, Follett L, Laychur A, Young A. The impact of self-efficacy on nonoperative treatment of atraumatic shoulder pain. J Osteopath Med 2022; 122:297-302. [PMID: 35218332 DOI: 10.1515/jom-2021-0132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 02/02/2022] [Indexed: 11/15/2022]
Abstract
CONTEXT Atraumatic shoulder pain is frequently encountered in primary care and surgical clinics. With increased recognition of the biopsychosocial model, there has been an increased emphasis on identifying patient factors associated with less effective coping strategies such as pain catastrophizing. It remains uncertain what impact self-efficacy has on the response to nonoperative treatment of shoulder pain. OBJECTIVES Our purpose is to determine the influence of patient coping strategies (self-efficacy) on the outcome of nonoperative treatment of atraumatic shoulder pain. We hypothesize that higher levels of self-efficacy are associated with increased self-reported function after nonoperative treatment. METHODS We conducted a retrospective case-control study for a consecutive series of patients seen in our clinic with nonoperatively managed atraumatic shoulder pain. Baseline demographics and range of motion were recorded. Patients completed the Simple Shoulder Test (SST), PROMIS Pain Interference (PI), and PROMIS Self-Efficacy for Managing Symptoms (SE). After 3 months of nonoperative treatment, patients were placed into two groups: patients who clinically improved (Group 1) and those that did not (Group 2), with clinical improvement defined as an increase of 2 or greater on the SST. RESULTS Seventy-eight patients returned for follow-up and completed all questionnaires. There were no statistically significant differences for age, sex, or tobacco use between the two groups. Half of the patients in our series had symptoms for >12 months, with rotator cuff syndrome being the most frequent diagnosis (40.0%). Patients in Group 1 had significantly higher PROMIS SE scores (42 vs. 39, p=0.0094) at initial evaluation. At 3-month follow-up, patients in Group 1 also had significantly lower Numeric Pain Rating Scale (NPRS) scores (4.5 vs. 6.5, p=0.0067), compared to Group 2. CONCLUSIONS Patients who experience clinical improvement with nonoperative treatment of atraumatic shoulder conditions demonstrate higher self-efficacy than patients who fail to improve. Guiding patients with atraumatic shoulder pain and low self-efficacy toward interventions aimed at improving coping strategies, rather than addressing musculoskeletal factors alone, may contribute to the goal of improving outcomes.

Abstract
Introduction: Rotator cuff tendinitis has been treated using various methods including physiotherapy, steroid injections and recently platelet rich plasma (PRP). Most of these methods aim at giving symptomatic relief rather than addressing the pathology. There is no clear consensus over the benefit of using PRP for tendinitis. We decided to do a prospective clinical study to demonstrate the efficacy of PRP and study the functional outcome in the treatment of rotator cuff tendinopathy. Material and Methods: Patients with shoulder pain for more than three months not responding to NSAIDs or physiotherapy with a diagnosis of rotator cuff tendinitis, confirmed by MRI, were included in the study. Patients with rotator cuff tear or any other shoulder pathology were excluded. We included a total of 30 patients who received 5ml of landmark guided PRP injection in the subacromial space followed by a six-week exercise program. Patients were followed-up at 3, 6 and 12 weeks. and were assessed clinically using the VAS, SPADI and Constant and Murley Score. Results: VAS score of patients improved from a pre injection score of 7.4 to a score of 1.9 in the 12th week. The mean SPADI score and Constant score improved from a pre injection score of 73.33 and 39.57 to a post injection score of 18.1 and 86.47, respectively. Conclusion: Platelet Rich Plasma injections showed good to excellent early results, in patients with rotator cuff tendinopathy with improvement in VAS, SPADI and Constant scores.

Abstract
BACKGROUND: Rotator cuff tear (RCT) is a common injury of the shoulder, especially middle-aged people. Nonoperative treatment, cortisone injections are only effective at an early stage. Open surgery causes postoperative atrophy of the deltoid muscle, so results are limited. Arthroscopic rotator cuff repair surgery has been performed in Vietnam for about ten years, with many advantages such as the ability to accurately assess the lesions and less invasive procedure. In order to have a clearer view, we performed a mid-term assessment of the effectiveness of this surgery. AIM: Evaluate results over 2 years of patients with rotator cuff tears treated with arthroscopic surgery and their quality of life. METHOD: A group of 30 patients were diagnosed with RCT and surgery by arthroscopy to treat at Hanoi Medical University Hospital and Saint Paul Hospital between Jun 2015 and April 2017. The results of the surgeries were assessed by the degree of pain, muscle power, motion of the shoulder joint according to UCLA shoulder score. Evaluate the quality of life through the Rotator Cuff-Quality of Life (RC-QoL) index. RESULTS: The average age was 60.7 years. Female / male ratio was 1.3. Thirty-six months ± 6.41 was the average follow-up time (min 27 – max 50 months). The shoulder function is recorded according to UCLA has an average score of 30.9, therein good and excellent result were 90 %. The mean RC-QoL index was 91.5%. CONCLUSION: Treatment of RCT by arthroscopic surgery that has been evaluated for a minimum of 2 years follow-up showed good results and high quality of patient’s life.

Abstract
BACKGROUND Rotator cuff disease is a major medical and economic burden due to a growing aging population, but management of rotator cuff tears remains controversial. We hypothesized that there is no difference in outcomes between patients who undergo rotator cuff repair and matched patients treated nonoperatively. METHODS After institutional review board approval, a prospective cohort of patients over 18 years of age who had a full-thickness rotator cuff tear seen on magnetic resonance imaging (MRI) were retrospectively evaluated. After clinical evaluation, each patient elected to undergo either rotator cuff repair or nonsurgical treatment. Demographic information was collected at enrollment, and self-reported outcome measures (the Normalized Western Ontario Rotator Cuff Index [WORCnorm], American Shoulder and Elbow Surgeons score [ASES], Single Assessment Numerical Evaluation [SANE], and pain score on a visual analog scale [VAS]) were collected at baseline and at 6, 12, and >24 months. The Functional Comorbidity Index (FCI) was used to assess health status at enrollment. The size and degree of atrophy of the rotator cuff tear were classified on MRI. Propensity score analysis was used to create rotator cuff repair and nonsurgical groups matched by age, sex, symptom duration, FCI, tear size, injury mechanism, and atrophy. The Student t test, chi-square test, and regression analysis were used to compare the treatment groups. RESULTS One hundred and seven patients in each group were available for analysis after propensity score matching. There were no differences between the groups with regard to demographics or rotator cuff tear characteristics. For all outcome measures at the time of final follow-up, the rotator cuff repair group had significantly better outcomes than the nonsurgical treatment group (p < 0.001). At the time of final follow-up, the mean outcome scores (and 95% confidence interval) for the surgical repair and nonsurgical treatment groups were, respectively, 81.4 (76.9, 85.9) and 68.8 (63.7, 74.0) for the WORCnorm, 86.1 (82.4, 90.3) and 76.2 (72.4, 80.9) for the ASES, 77.5 (70.6, 82.5) and 66.9 (61.0, 72.2) for the SANE, and 14.4 (10.2, 20.2) and 27.8 (22.5, 33.5) for the pain VAS. In the longitudinal regression analysis, better outcomes were independently associated with younger age, shorter symptom duration, and rotator cuff repair. CONCLUSIONS Patients with a full-thickness rotator cuff tear reported improvement in pain and functional outcome scores with nonoperative treatment or surgical repair. However, patients who were offered and chose rotator cuff repair reported greater improvement in outcome scores and reduced pain compared with those who chose nonoperative treatment.

Abstract
Objectives This study aims to investigate and compare the efficacy of platelet-rich plasma (PRP) injection, corticosteroid injection, and physical therapy in addition to exercise treatment on pain, shoulder functions, and quality of life in patients with subacromial impingement syndrome (SAIS). Patients and methods Ninety patients (37 males, 53 females; mean age 48.99 years; range, 33 to 60 years) who were diagnosed as Stage 2 SAIS were included in the study. Patients were randomized into three groups. PRP injection was administered into the subacromial space of the affected shoulder in group 1, corticosteroid injection was administered in the subacromial joint space in group 2, and 10 sessions of physical therapy were given in group 3 five times weekly including transcutaneous electrical nerve stimulation, ultrasound, and hot packs. Moreover, an exercise program was administered in all groups. Visual Analog Scale (VAS) was used to determine the resting and moving shoulder pain; while the Shoulder Disability Questionnaire, Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire, and the University of California, Los Angeles Shoulder Rating Scale (UCLA SRS) were used to evaluate the functionality of patients. Quality of life was analyzed using a generic Short Form 36 (SF-36). Results All scores improved in all three groups compared with the period before treatment. Comparison of the groups showed higher scores in group 1 compared to groups 2 and 3 at week eight on QuickDASH, UCLA SRS, VAS at rest and during activity, and SF-36 pain subgroup scores. Conclusion All three treatment modalities were effective in the treatment of SAIS. However, we suggest that the inexpensive and noninvasive methods of physical therapy and exercise should be the first preferred treatment in SAIS owing to causing no adverse events.

Abstract
BACKGROUND To date, there are no published data on the use of devices in the management of rotator cuff tear (RCT). AIM The aim of this study was to evaluate the effect of supervised arm cycloergometer training on pain during activities and shoulder functionality in patients with symptomatic full-thickness RCT. DESIGN This is a prospective randomized controlled pilot study. SETTING Outpatients of our Rehabilitation Unit. POPULATION In this pilot study, 40 elderly outpatients (>70 years) with RCT were randomized to two groups: cycloergometer (CYC) vs. control patients. METHODS All patients underwent a common outpatient rehabilitation exercise program consisting of ten 30-min sessions (5 sessions/week). At discharge, CYC patients received 15-min training with an arm cycloergometer and were invited to use the cycloergometer at home 20 min/twice a day. Control patients were invited to continue the standard exercises. During the 6-month study period CYC patients, but not control patients, received educational reinforcement monthly from the nurse of the telemedicine service. Outcomes assessed, between admission (T0) and 6-month follow-up (T6), were: pre to postpain during activities, active and passive ROMsum, ROM-painsum, revised Constant Total Score, and Health Assessment Questionnaire (HAQ). RESULTS At T6, CYC patients showed a significant improvement in all outcome measures with respect to T0 (all: P<0.001). CYC patients showed also significant improvement in passive forward elevation, abduction, and external rotation of shoulder, as well as in active ROMsum and ROM-painsum in all single shoulder movements, and significant improvement in the HAQ items: dressing/grooming, eating, hygiene, reach, and common daily activities. At T6 the CYC group had lower pain during activities (P<0.01) and higher revised constant total score (P<0.01), ROM-painsum (P<0.05) and active ROMsum (P<0.05) than control patients. Home cycloergometer use was inversely associated to pain during activities (P<0.01) and revised Constant Total Score (P<0.01) at T6. CONCLUSIONS A short program of shoulder passive exercises and cuff strengthening exercises followed by regular use of the cycloergometer for 6 months at home can reduce pain and improve shoulder functionality in RCT patients. CLINICAL REHABILITATION IMPACT Our findings indicate that the cycloergometer may be useful in patients with RCT when regularly used at home and suggest use of this mechanical device in rehabilitation programs for these patients.

Abstract
INTRODUCTION We examined practice patterns and surgical indications in the management of common shoulder procedures by surgeons practicing at physician-owned facilities. METHODS This study was a retrospective analysis of 501 patients who underwent arthroscopic shoulder procedures performed by five surgeons in our practice at one of five facilities during an 18-month period. Two of the facilities were physician-owned, and three of the five surgeons were shareholders. Demographics, insurance status, symptom duration, time from injury/symptom onset to the decision to perform surgery (at which time surgical consent is obtained), and time to schedule surgery were studied to determine the influence of facility type and physician shareholder status. RESULTS Median duration of symptoms before surgery was significantly shorter in workers' compensation patients than in non-workers' compensation patients (47% less; P < 0.0001) and in men than in women (31% less; P < 0.001), but was not influenced by shareholder status or facility ownership (P > 0.05). Time between presentation and surgical consent was not influenced by facility ownership (P = 0.39) or shareholder status (P = 0.50). Time from consent to procedure was 13% faster in physician-owned facilities than in non-physician-owned facilities (P = 0.03) and 35% slower with shareholder physicians than with nonshareholder physicians (P < 0.0001). DISCUSSION The role of physician investment in private healthcare facilities has caused considerable debate in the orthopaedic surgery field. To our knowledge, this study is the first to examine the effects of shareholder status and facility ownership on surgeons' practice patterns, surgical timing, and measures of nonsurgical treatment before shoulder surgery. CONCLUSIONS Neither shareholder status nor facility ownership characteristics influenced the speed with which surgeons determined that shoulder surgery was indicated or surgeons' use of preoperative nonsurgical treatment. After the need for surgery was determined, patients underwent surgery sooner at physician-owned facilities than at non-physician-owned facilities and with nonshareholder physicians than with shareholder physicians.

Abstract
[Purpose] In rotator cuff tendon disease (RCTD), anamnesis is as important as clinical
findings and anatomic/radio diagnostic examination. This study aimed to investigate the
clinical features of patients diagnosed with RCTD using clinical and radiological methods
between March 2015 and August 2015 at Malatya Research and Training Hospital Physical
Medicine and Rehabilitation department. [Subjects and Methods] The study included 178
patients who were diagnosed with RCTD (128 females and 50 males). A questionnaire
comprising 33 questions was given to each patient. [Results] Eighty-eight of the patients
(49.9%) had an involvement on their right side, eighty-four (47.1%) had an involvement on
their left side, and 6 had bilateral involvement. Mean visual analog scale (VAS) score was
found to be statistically significant in favor of female patients. A statistically
significant correlation was found between educational status and VAS. The body mass index
(BMI) of the female patients was found to be higher than that of the male patients.
Statistically significant correlation between doing risky work and gender showed that
males were at a higher risk. [Conclusion] RCDT is more seen in people who have high BMI
and are at their 50s. Pain complaint and BMI were found higher in female patients. DM,
thyroid and cardiac diseases were seen more in the patients who are diagnosed with RCTD
relative to the healthy population.

Abstract
Epidemiologic data show that the number of middle aged (>40 yr) and elderly (>65 yr) individuals continues to increase steadily, creating an expanding need for sports medicine care. Management of injuries in this subset of patients is expanding well beyond sustaining a patient's ability to perform activities of daily living. In fact, many older individuals increasingly expect to maintain reasonably high activity levels throughout their lifespan as well as after musculoskeletal injury. While a number of the emerging physiologic benefits of physical activity in older patients have been outlined, no recent review has outlined the current best surgical techniques, rehabilitation protocols, and return-to-sport recommendations for older athletes after soft-tissue repair or reconstruction as well as joint replacement. The goal of orthopaedic care in the elderly patient is shifting from simple pain relief toward return to athletic activity.

Abstract
BACKGROUND Failure of rotator cuff healing is a common complication despite the rapid development of surgical repair techniques for the torn rotator cuff. PURPOSE To verify the effect of atelocollagen on tendon-to-bone healing in the rabbit supraspinatus tendon compared with conventional cuff repair. STUDY DESIGN Controlled laboratory study. METHODS A tear of the supraspinatus tendon was created and repaired in 46 New Zealand White rabbits. They were then randomly allocated into 2 groups (23 rabbits per group; 15 for histological and 8 for biomechanical test). In the experimental group, patch-type atelocollagen was implanted between bone and tendon during repair; in the control group, the torn tendon was repaired without atelocollagen. Each opposite shoulder served as a sham (tendon was exposed only). Histological evaluation was performed at 4, 8, and 12 weeks. Biomechanical tensile strength was tested 12 weeks after surgery. RESULTS Histological evaluation scores of the experimental group (4.0 ± 1.0) were significantly superior to those of the control group (7.7 ± 2.7) at 12 weeks ( P = .005). The load to failure was significantly higher in the experimental group (51.4 ± 3.9 N) than in the control group (36.4 ± 5.9 N) ( P = .001). CONCLUSION Histological and biomechanical studies demonstrated better results in the experimental group using atelocollagen in a rabbit model of the supraspinatus tendon tear. CLINICAL RELEVANCE Atelocollagen patch could be used in the cuff repair site to enhance healing.

Effects of the pulsed electromagnetic field PST® on human tendon stem cells: a controlled laboratory study. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 16:293. [PMID: 27538432 PMCID: PMC4989537 DOI: 10.1186/s12906-016-1261-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/08/2015] [Accepted: 08/05/2016] [Indexed: 12/27/2022]
Abstract
Background Current clinical procedures for rotator cuff tears need to be improved, as a high rate of failure is still observed. Therefore, new approaches have been attempted to stimulate self-regeneration, including biophysical stimulation modalities, such as low-frequency pulsed electromagnetic fields, which are alternative and non-invasive methods that seem to produce satisfying therapeutic effects. While little is known about their mechanism of action, it has been speculated that they may act on resident stem cells. Thus, the purpose of this study was to evaluate the effects of a pulsed electromagnetic field (PST®) on human tendon stem cells (hTSCs) in order to elucidate the possible mechanism of the observed therapeutic effects. Methods hTSCs from the rotator cuff were isolated from tendon biopsies and cultured in vitro. Then, cells were exposed to a 1-h PST® treatment and compared to control untreated cells in terms of cell morphology, proliferation, viability, migration, and stem cell marker expression. Results Exposure of hTSCs to PST® did not cause any significant changes in proliferation, viability, migration, and morphology. Instead, while stem cell marker expression significantly decreased in control cells during cell culturing, PST®-treated cells did not have a significant reduction of the same markers. Conclusions While PST® did not have significant effects on hTSCs proliferation, the treatment had beneficial effects on stem cell marker expression, as treated cells maintained a higher expression of these markers during culturing. These results support the notion that PST® treatment may increase the patient stem cell regenerative potential.

J Shoulder Elbow Surg 2016; 25:12-21. [PMID: 26264504 DOI: 10.1016/j.jse.2015.06.023] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2015] [Revised: 06/16/2015] [Accepted: 06/22/2015] [Indexed: 02/06/2023]
Abstract
BACKGROUND Patients with rotator cuff tears often recall a specific initiating event (traumatic), whereas many cannot (nontraumatic). It is unclear how important a history of trauma is to the outcomes of rotator cuff repair. METHODS This question was addressed in a study cohort of 1300 consecutive patients who completed a preoperative questionnaire regarding their shoulder injury and had a systematic evaluation of shoulder range of motion and strength, a primary arthroscopic rotator cuff repair performed by a single surgeon, an ultrasound scan, and the same subjective and objective measurements made of their shoulder 6 months after surgery. Post hoc, this cohort was separated into 2 groups: those who reported no history of trauma on presentation (n = 489) and those with a history of traumatic injury (n = 811). RESULTS The retear rate in the group with no history of trauma was 12%, whereas that of the group with a history of trauma was 14% (P = .36). Those patients with a history of shoulder trauma who waited longer than 24 months had higher retear rates (20%) than those who had their surgery earlier (13%) (P = .040). CONCLUSION Recollection of a traumatic initiating event had little effect on the outcome of arthroscopic rotator cuff repair. Duration of symptoms was important in predicting retears if patients recalled a specific initiating event but not in patients who did not recall any specific initiating event. Patients with a history of trauma should be encouraged to have their rotator cuff tear repaired within 2 years.

Abstract
This paper proposes a model for recognizing motions performed during rehabilitation exercises for frozen shoulder conditions. The model consists of wearable wireless sensor network (WSN) inertial sensor nodes, which were developed for this study, and enables the ubiquitous measurement of bodily motions. The model employs the back propagation neural network (BPNN) algorithm to compute motion data that are formed in the WSN packets; herein, six types of rehabilitation exercises were recognized. The packets sent by each node are converted into six components of acceleration and angular velocity according to three axes. Motor features such as basic acceleration, angular velocity, and derivative tilt angle were input into the training procedure of the BPNN algorithm. In measurements of thirteen volunteers, the accelerations and included angles of nodes were adopted from possible features to demonstrate the procedure. Five exercises involving simple swinging and stretching movements were recognized with an accuracy of 85%–95%; however, the accuracy with which exercises entailing spiral rotations were recognized approximately 60%. Thus, a characteristic space and enveloped spectrum improving derivative features were suggested to enable identifying customized parameters. Finally, a real-time monitoring interface was developed for practical implementation. The proposed model can be applied in ubiquitous healthcare self-management to recognize rehabilitation exercises.

Abstract
INTRODUCTION Rotator cuff tears (RCT) are a common source of shoulder pain, with an incidence ranging between 5% and 40%. The influence of corticosteroid injections on the incidence of RCT remains unknown. The aim of this study was to estimate the incidence of full-thickness RCT 12 weeks after a subacromial corticosteroid injection in patients with shoulder pain. PATIENTS AND METHOD We made a prospective, open-label study in patients with unilateral painful shoulder without previous local corticosteroid injection. Ultrasound assessments were made at the first (baseline) and last (Week 12) visits by an experienced radiologist. A rheumatologist did the clinical examination. Patients with full-thickness RCT at the first visit were excluded. All patients received a subacromial injection of triamcinolone acetate 40 mg. RESULTS One hundred and two patients with shoulder pain were initially evaluated: 49 (48%) were excluded due to full-thickness RCT on ultrasound assessment. Therefore, 53 patients completed the study (34 female, mean age 60.8 years, mean time of evolution 9.6 months). In the first ultrasound evaluation, 24 patients (45.3%) had a partial-thickness tear. At 12 weeks after the corticosteroid injection, 9 (17%) patients developed full-thickness RCT, 66.6% of which occurred in patients with previous partial-thickness RCT. Corticosteroid injection significantly improved symptoms (p = 0.0001 for pain VAS score) and range of motion (p = 0.002 for forward elevation and external rotation). CONCLUSIONS Seventeen percent of patients with shoulder pain suffered a full-thickness RCT 12 weeks after subacromial corticosteroid injection. Corticosteroid injection is highly effective in improving clinical symptoms of rotator cuff tendinopathy at 12 weeks.

Abstract
BACKGROUND Rotator cuff tendinopathy (RCT) is a significant source of disability and loss of work. Platelet-rich plasma (PRP) has been suggested to be beneficial in the treatment of RCT. PURPOSE To investigate the effect of PRP injections on pain and shoulder functions in patients with chronic RCT. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A total of 40 patients, 18 to 70 years of age, with (1) a history of shoulder pain for >3 months during overhead-throwing activities, (2) MRI findings of RCT or partial tendon ruptures, and (3) a minimum 50% reduction in shoulder pain with subacromial injections of an anesthetic were included in this placebo-controlled, double-blind randomized clinical trial. Patients were randomized into a PRP group (n = 20) or placebo group (n = 20). Patients received an ultrasound-guided injection into the subacromial space that contained either 5 mL of PRP prepared from autologous venous blood or 5 mL of saline solution. All patients underwent a 6-week standard exercise program. Outcome measures (Western Ontario Rotator Cuff Index [WORC], Shoulder Pain and Disability Index [SPADI], 100-mm visual analog scale [VAS] of shoulder pain with the Neer test, and shoulder range of motion) were assessed at baseline and at 3, 6, 12, and 24 weeks and 1 year after injection. RESULTS Comparison of the patients revealed no significant difference between the groups in WORC, SPADI, and VAS scores at 1-year follow-up (P = .174, P = .314, and P = .904, respectively). Similar results were found at other assessment points. Within each group, the WORC, SPADI, and VAS scores showed significant improvements compared with baseline at all time points (P < .001). In the range of motion measures, there were no significant group × time interactions. CONCLUSION At 1-year follow-up, a PRP injection was found to be no more effective in improving quality of life, pain, disability, and shoulder range of motion than placebo in patients with chronic RCT who were treated with an exercise program.

Abstract
AIM The aim of this prospective study was to evaluate the effect of corticosteroids intra-articular injections on pain in patients with rotator cuff tear (RCT), and to identify predictors for pain outcomes. METHODS A total of 60 patients with RCT were enrolled. All patients underwent rehabilitation; 20 patients received a single intra-articular injection of 40 mg triamcinolone acetonide and 20 patients had a repeat injection at a 21-day interval. Backward stepwise regression analysis was used to predict effectiveness and improvement of pain. The independent variables were age, sex, symptom duration, tear size, passive range of motion (ROM), active ROM, non-steroidal anti-inflammatory drugs request, pain at rest, number of triamcinolone injections and severity of osteoarthritis at admission. RESULTS At 3 and 6 months, patients who received triamcinolone had higher effectiveness and improvement in pain during activities and pain at night than those of control group. At the 3-month interval post-therapy, active ROM was the only predictor for effectiveness in pain during activity, effectiveness in pain at night and improvement in pain at night. Six months after therapy, active ROM was a predictor for improvement in pain at night. Age was a predictor for effectiveness in pain at night, whereas tear size of RCT was a predictor for effectiveness and improvement in pain during activity. CONCLUSIONS Corticosteroids can relieve pain in RCT. Active ROM is the most important predictor of pain outcomes. This finding can be useful to physicians when deciding on the type of patients who might best benefit from intra-articular injections of corticosteroids.

Abstract
Rotator cuff injury comprises a continual spectrum of lesions ranging from tendinopathy, which may progress to partial- or full-thickness tear. This progression may be influenced by the interplay of extrinsic and intrinsic factors. We describe the case of a 29-year-man who presented with right shoulder pain for one year. His initial magnetic resonance (MR) arthrogram showed supraspinatus tendinopathy. Subsequent MR arthrogram, obtained after a road traffic accident, showed a bursal-sided partial-thickness tear of the supraspinatus tendon. In view of his worsening clinical symptoms, surgery was performed ten months later, revealing a full-thickness rotator cuff tear near the tendon insertion, with a tight subacromial space and bony protuberance of the humeral head. The pathogenesis of rotator cuff injuries, the roles of different imaging modalities in the diagnosis of rotator cuff injuries, as well as the advantages and limitations of various radiological modalities, are discussed.

Abstract
The etiology of rotator cuff disease is likely multifactorial, including age-related degeneration and microtrauma and macrotrauma. The incidence of rotator cuff tears increases with aging with more than half of individuals in their 80s having a rotator cuff tear. Smoking, hypercholesterolemia, and genetics have all been shown to influence the development of rotator cuff tearing. Substantial full-thickness rotator cuff tears, in general, progress and enlarge with time. Pain, or worsening pain, usually signals tear progression in both asymptomatic and symptomatic tears and should warrant further investigation if the tear is treated conservatively. Larger (>1-1.5 cm) symptomatic full-thickness cuff tears have a high rate of tear progression and, therefore, should be considered for earlier surgical repair in younger patients if the tear is reparable and there is limited muscle degeneration to avoid irreversible changes to the cuff, including tear enlargement and degenerative muscle changes. Smaller symptomatic full-thickness tears have been shown to have a slower rate of progression, similar to partial-thickness tears, and can be considered for initial nonoperative treatment due to the limited risk for rapid tear progression. In both small full-thickness tears and partial-thickness tears, increasing pain should alert physicians to obtain further imaging as it can signal tear progression. Natural history data, along with information on factors affecting healing after rotator cuff repair, can help guide surgeons in making appropriate decisions regarding the treatment of rotator cuff tears. The management of rotator cuff tears should be considered in the context of the risks and benefits of operative versus nonoperative treatment. Tear size and acuity, the presence of irreparable changes to the rotator cuff or glenohumeral joint, and patient age should all be considered in making this decision. Initial nonoperative care can be safely undertaken in older patients (>70 years old) with chronic tears; in patients with irreparable rotator cuff tears with irreversible changes, including significant atrophy and fatty infiltration, humeral head migration, and arthritis; in patients of any age with small (<1 cm) full-thickness tears; or in patients without a full-thickness tear. Early surgical treatment can be considered in significant (>1 cm-1.5 cm) acute tears or young patients with full-thickness tears who have a significant risk for the development of irreparable rotator cuff changes.

Abstract
Rotator cuff injuries are common problems and a frequent reason for patients to present to primary care physicians. These injuries are seen more frequently now with the aging population. These muscles allow for movement of the arm in overhead activities and controlled movements through space. A thorough physical examination can lead to the diagnosis of rotator cuff pathology. Radiographic imaging may offer some insight into the underlying pathology, and magnetic resonance imaging provides for excellent visualization of the rotator cuff. Many rotator cuff tears, especially partial tears, will symptomatically improve with conservative management. Surgical treatment may offer improved pain relief and function in those patients for whom nonoperative care is insufficient. In cases in which rotator cuff repair is not possible, the reverse total shoulder arthroplasty is a possibility. New technologies are also under investigation that allow for biological augmentation of rotator cuff tears.

Abstract
Chronic tendon pathologies (eg, rotator cuff tears, Achilles tendon ruptures) are common, painful, debilitating, and a significant source of medical expense. Treatment strategies for managing tendon pathologies vary widely in invasiveness and cost, with little scientific basis on which to base treatment selection. Conventional techniques for assessing the outcomes of physical therapy or surgical repair typically rely on patient-based assessments of pain and function, physical measures (eg, strength, range of motion, or stability), and qualitative assessments using magnetic resonance imaging or ultrasound. Unfortunately, these conventional techniques provide only an indirect assessment of tendon function. The inability to make a direct quantitative assessment of the tendon's mechanical capabilities may help to explain the relatively high rate of failed tendon repairs and has led to an interest in the development of tools for directly assessing in vivo tendon function. The purpose of this article is to review methods for assessing tendon function (ie, mechanical properties and capabilities) during in vivo activities. This review will describe the general principles behind the experimental techniques and provide examples of previous applications of these techniques. In addition, this review will characterize the advantages and limitations of each technique, along with its potential clinical utility. Future efforts should focus on developing broadly translatable technologies for quantitatively assessing in vivo tendon function. The ability to accurately characterize the in vivo mechanical properties of tendons would improve patient care by allowing for the systematic development and assessment of new techniques for treating tendon pathologies.

Abstract
Background Subacromial disorders are considered to be one of the most common pathologies affecting the shoulder. Optimal therapy for shoulder pain (SP) in primary care is yet unknown, since clinical history and physical examination do not provide decisive evidence as to the patho-anatomical origin of the symptoms. Optimal decision strategies can be furthered by applying ultrasound imaging (US), an accurate method in diagnosing SP, demonstrating a clear relationship between diagnosis and available therapies. Yet, the clinical cost-effectiveness of applying US in the management of SP in primary care has not been studied. The aim of this paper is to describe the design and methods of a trial assessing the cost-effectiveness of ultrasound imaging as a diagnostic triage tool to improve management of primary care patients with non-chronic shoulder pain. Methods/Design This randomised controlled trial (RCT) will involve 226 adult patients with suspected subacromial disorders recruited by general practitioners. During a Qualification period of two weeks, patients receive care as usual as advised by the Dutch College of General Practitioners, and patients are referred for US. Patients with insufficient improvement qualify for the RCT. These patients are then randomly assigned to the intervention or the control group. The therapies used in both groups are the same (corticosteroid injections, referral to a physiotherapist or orthopedic surgeon) except that therapies used in the intervention group will be tailored based on the US results. Ultrasound diagnosed disorders include tendinopathy, calcific tendinitis, partial and full thickness tears, and subacromial bursitis. The primary outcome is patient-perceived recovery at 52 weeks, using the Global Perceived Effect questionnaire. Secondary outcomes are disease specific and generic quality of life, cost-effectiveness, and the adherence to the initial applied treatment. Outcome measures will be assessed at baseline, 13, 26, 39 and 52 weeks after inclusion. An economic evaluation will be performed from both a health care and societal perspective with a time horizon of 52 weeks. Discussion The results of this trial will give unique evidence regarding the cost-effectiveness of US as a diagnostic triage tool in the management of SP in primary care.

Abstract
Outcomes after rotator cuff surgery are typically assessed with measures of strength, joint motion, or pain, but these measures do not provide a direct assessment of tissue function as healing progresses. To address this limitation, this manuscript describes biplane X-ray analysis as a technique for quantifying in vivo soft-tissue deformation. Tantalum beads were implanted in the humerus and infraspinatus tendon in a canine model of tendon injury and repair. Biplane X-ray images were acquired during treadmill trotting and tissue deformation was estimated from the three-dimensional bead positions. Changes over time were characterized by the mean, range, and normalized range (i.e., range/mean) of interbead distance. Intact tendon repair tissue demonstrated significant decreases over time in the mean (p = 0.003), range (p = 0.001), and normalized range (p = 0.001) of interbead distance. Failed tendon repair tissue demonstrated significant decreases over time in the range (p = 0.05) and normalized range (p = 0.04) of interbead distance. In an uninjured control, differences over time in the interbead distance parameters were not detected. This approach is a promising technique for estimating changes over time in soft-tissue deformation. These preliminary data indicate appreciable differences between normal tendons, intact repairs, and failed repairs.

Abstract
Despite improvements in the understanding of rotator cuff pathology and advances in surgical treatment options, repairs of chronic rotator cuff tears often re-tear or fail to heal after surgery. Hence, there is a critical need for new regenerative repair strategies that provide effective mechanical reinforcement of rotator cuff repair as well as stimulate and enhance the patient's intrinsic healing potential. This article will discuss and identify appropriate models for translating regenerative medicine therapies for rotator cuff repair. Animal models are an essential part of the research and development pathway; however, no one animal model reproduces all of the features of the human injury condition. The rat shoulder is considered the most appropriate model to investigate the initial safety, mechanism, and efficacy of biologic treatments aimed to enhance tendon-to-bone repair. Whereas large animal models are considered more appropriate to investigate the surgical methods, safety and efficacy of the mechanical-or combination biologic/mechanical-strategies are ultimately needed for treating human patients. The human cadaver shoulder model, performed using standard-of-care repair techniques, is considered the best for establishing the surgical techniques and mechanical efficacy of various repair strategies at time zero. While preclinical models provide a critical aspect of the translational pathway for engineered tissues, controlled clinical trials and postmarketing surveillance are also needed to define the efficacy, proper indications, and the method of application for each new regenerative medicine strategy.

Abstract
Rotator cuff tears are a common cause of shoulder pain and disability. Although many studies have reported about the surgical results of full-thickness tears of the rotator cuff, there are few studies about the efficacy of conservative treatment. The aim of this study was to investigate the efficacy of conservative treatment in patients with full-thickness rotator cuff tears by using objective and subjective measurements. Twenty patients with full-thickness rotator cuff tears were included in the study. Outcome measures were range of motion, pain and function according to the shoulder index of the American Shoulder and Elbow Surgeons (ASES), Constant score, Short-Form 36 Health Survey (SF-36), isokinetic shoulder strength, and patient response. Patients were assessed at baseline and after 6 months. In addition, patients were contacted by telephone at 1 year and at 3 years for functional assessment according to ASES, and patient response. The treatment protocol included activity modification, oral nonsteroidal antiinflammatory medications, physical modalities, and a specific exercise program. Statistically significant improvements were obtained in range of motion, pain and function scores according to ASES, Constant score, SF-36 scores, and isokinetic strength (P < 0.05). At the 6-month evaluation, 11 patients (55%) reported that they were "much better", and 9 patients (45%) "better". Conservative treatment of full-thickness rotator cuff tears yields satisfactory results both subjectively and objectively.

Abstract
A systematic review of the literature was performed to evaluate the role of exercise in treating rotator cuff impingement and to synthesize a standard evidence-based rehabilitation protocol. Eleven randomized, controlled trials (level 1 and 2) evaluating the effect of exercise in the treatment of impingement were identified. Data regarding demographics, methodology, and outcomes of pain, range of motion, strength, and function were recorded. Individual components of each rehabilitation program were catalogued. Effectiveness was determined by statistical and clinical significance. Although many articles had methodologic concerns, the data demonstrate that exercise has statistically and clinically significant effects on pain reduction and improving function, but not on range of motion or strength. Manual therapy augments the effects of exercise, yet supervised exercise was not different than home exercise programs. Information regarding specific components of the exercise programs was synthesized into a gold standard rehabilitation protocol for future studies on the nonoperative treatment of rotator cuff impingement.

Abstract
Success rates relating to relief from pain and improved function following open reconstruction of the rotator cuff have been documented in many studies. At least for small to medium-size tears the question currently arises of whether an arthroscopic repair would not also give good treatment results. At present, however, the results of arthroscopic repair are not yet comparable to those yielded by the open techniques, at least in terms of recurrent defects especially in the case of massive tears (affecting more than two tendons). Open surgical repair is currently still recommended for all patients who require maximal postoperative function and strength and for elderly patients. Open repairs have a lower rate of re-rupture than arthroscopic repairs, but arthroscopic repair offers the benefits of lower morbidity. The decision on which technique is indicated should be made by an experienced surgeon with special training in this area and with due consideration for newer aspects in diagnostic imaging techniques, so as to avoid unsatisfactory results. In certain cases of irreparable cuff tears affecting two tendons and with fatty infiltration of the muscle and substantial loss of function muscle transfer can be considered in active patients; this can offer some functional improvement in the medium to long term, but do not lead to full restoration of function.

Abstract
Large and retracted rotator cuff tendon tears fail to repair or retear after surgical intervention. This study attempted to develop novel tissue-engineering approaches using tenocyte-seeded bioscaffolds for tendon reconstruction of massive rotator cuff tendon defect in rabbits. Porcine small intestine submucosa (Restore) and type I/III collagen bioscaffold (ACI-Maix) were chosen as bioscaffold carriers for autologous tenocytes. Biological characterization of autologous tenocytes was conducted before the implantation. The tenocyte-seeded bioscaffolds were implanted as interposition grafts to reconstruct massive rotator cuff tendon defects in rabbits. In situ reimplantation of the autologous rotator cuff tendon, excised during defect creation, served as a positive control. Histological outcomes were analyzed and semi-quantitatively graded at 4 and 8 weeks after surgery. At 4 weeks, both tenocyte-seeded bioscaffolds displayed inflammatory reaction similar to bioscaffold-only cuff reconstruction, and the histological grading were inferior to control repair. However, at 8 weeks, inflammatory reaction of both tenocyte-seeded bioscaffolds were dramatically less than with bioscaffold alone. In addition, bioscaffolds seeded with tenocytes generated a histological appearance similar to that of the positive control. The implantation of autologous tenocytes on collagen-based bioscaffolds results in better rotator cuff tendon healing and remodeling than with the implantation of bioscaffold alone.

Abstract
STUDY DESIGN Prospective, multicenter research design. OBJECTIVES To assess functional and health status outcomes in patients following a physical therapy program after rotator cuff repair surgery, and to determine the impact of selected patient medical comorbidities on rehabilitation outcomes. BACKGROUND While authors have studied the influence of multiple factors on patient outcomes after rotator cuff repair surgery, little research has been done on the impact of comorbidities, particularly as it relates to establishing an accurate patient prognosis. eighteen patients who had recently undergone a rotator cuff repair surgical procedure were recruited at 1 of 30 Physiotherapy Associates, Inc outpatient clinics located in 13 states. A rehabilitation protocol was implemented and included the following interventions, as indicated: therapeutic exercise, manual therapy, electrotherapeutic modalities, and physical agents. Patient health history factors were documented during the initial examination, including age, race, body mass index, smoking, rotator cuff tear size, type of surgical procedure, and selected medications and comorbidities. The Disabilities of the Arm, Shoulder, and Hand (DASH) and the Short-Form-36 (SF-36) were completed prior to rehabilitation, at discharge, and at 6 months postdischarg RESULTS DASH andmost SF-36 domain mean scores obtained postrehabilitation were significantly improved from pretherapy scores. Most health status outcomes were maintained at 6-month follow-up, with slight further improvement noted in SF-36 physical dimensions and DASH scores. Having a greater number of comorbidities was associated with worse postrehabilitation SF-36 scores, but not with the DASH shoulder function scores. The mean change scores (difference between prerehabilitation and postrehabilitation status) for the DASH and SF-36 were not significantly different for patients with 0 to 1, 2, or at least 3 or more comorbidities (except for emotional role). In regression analyses a model with baseline physical function score (P = .0001), age (P = .03), and number of comorbidities (P = .003) fitted the data well and explained 38% of the variance in the physical function score at discharge. CONCLUSIONS A higher number of comorbidities had a negative effect on general health status outcomes but not on shoulder function outcomes at the time of patient discharge following rehabilitation. Despite a negative effect of more comorbidities on health status outcomes, the specific number of medical comorbidities did not affect the overall level of improvement prerehabilitation to postrehabilitation in function and health status. The findings describing the influence of comorbidities on rehabilitation outcomes may assist therapists in establishing accurate patient prognosis.

Abstract
Animal shoulder models are used to systematically investigate the factors influencing rotator cuff injury and repair. Each model has advantages and disadvantages that must be considered in the context of the specific research questions being asked. This study evaluated the utility of the canine model for studies of acute, full-thickness rotator cuff tendon injury and repair. We found that time-zero failure load is dependent on the suture type and configuration used for repair. Acute, full-width tendon repairs fail anatomically within the first days after surgery in the canine model, regardless of suture type, suture configuration, or postoperative protocol. Robust scar tissue forms in the gap between the failed tendon end and the humerus, which can be visually, mechanically, and histologically misconstrued as tendon if an objective test of repair connectivity is not performed. We conclude that a full-width injury and repair model in the canine will provide a rigorous test of whether a new repair strategy or postoperative protocol, such as casting or temporary muscle paralysis, can maintain repair integrity in a high-load environment. Alternatively, a partial-width tendon injury model allows loads to be shared between the tendon repair and the remaining intact portion of the infraspinatus tendon and prohibits complete tendon retraction. Thus a partial-width injury in the canine may model the mechanical environment of many single tendon tears in the human injury condition and warrants further investigation.

Abstract
The rotator cuff muscles generate torque forces to move the humerus while acting in concord to produce balanced compressive forces to stabilize the glenohumeral joint. Thus, rotator cuff tears are often associated with loss of shoulder strength and stability, which are crucial for optimal shoulder function. The dimensions and extent of rotator cuff tears, the condition of the involved tendon, tear morphologic features, involvement of the subscapularis and infraspinatus tendons or of contiguous structures (eg, rotator interval, long head of the biceps brachii tendon, specific cuff tendons), and evidence of muscle atrophy may all have implications for rotator cuff treatment and prognosis. Magnetic resonance imaging can demonstrate the extent and configuration of rotator cuff abnormalities, suggest mechanical imbalance within the cuff, and document abnormalities of the cuff muscles and adjacent structures. A thorough understanding of the anatomy and function of the rotator cuff and of the consequences of rotator cuff disorders is essential for optimal treatment planning and prognostic accuracy. Identifying the disorder, understanding the potential clinical consequences, and reporting all relevant findings at rotator cuff imaging are also essential.

Abstract
Repair of massive rotator cuff tears in the elderly can be challenging because of degenerative, retracted, and contracted tendons producing an extensive defect. The quality of the tendon and particularly the bone of the proximal humerus is an inherent weakness in the repaired construct. We report a method that secures the rotator cuff to a fixation post placed in cortical bone at the surgical neck of the humerus, bypassing the weakest point. This is an evolution of techniques designed to fix to the greater tuberosity. We reviewed 32 repairs (16 men and 14 women; mean age, 68 years) with a minimum of 2 years' follow-up (mean, 4.3 years). Constant scores improved from a mean of 27.9 preoperatively to 78.2 postoperatively. Pain scores improved from 8.2 to 1.9, with 87% of patients being satisfied with the results of surgery. This is a robust construct that is easily learned and able to solve a technical problem.

Abstract
Ultrasonography (US) has been shown to be an effective imaging modality in the evaluation of both rotator cuff and non-rotator cuff disorders, usually serving in a complementary role to magnetic resonance imaging of the shoulder. US technique for shoulder examination depends on patient positioning, scanning protocol for every tendon and anatomic part, and dynamic imaging. The primary US signs for rotator cuff supraspinatus tendon tears are tendon nonvisualization for complete tears, focal tendon defect for full-thickness tears, a hypoechoic defect of the articular side of the tendon for an articular-side partial-thickness tear, and flattening of the bursal surface of the tendon for a bursal-side partial-thickness tear. Secondary US signs such as cortical irregularity of the greater tuberosity and joint and subacromial-subdeltoid bursal fluid are helpful when correlated with the primary signs. Tendon degeneration, tendinosis, and intrasubstance tear are demonstrated as internal heterogeneity. Long-head biceps tendon abnormalities include instability, acute or chronic tear, and tendinosis. The acromioclavicular joint is assessed for dislocation, fluid collection, cysts, and bone erosions. Other non-rotator cuff disorders include synovial disorders such as adhesive capsulitis and synovial osteochondromatosis; degenerative disorders such as osteoarthritis, amyloid arthropathy, hemarthrosis, and chondrocalcinosis; infectious disorders such as septic arthritis and bursitis; and space-occupying lesions.

Abstract
BACKGROUND Long-standing tears of the rotator cuff can lead to substantial and perhaps irreversible changes in the affected rotator cuff muscles. We developed a chronic rotator cuff tear in a canine model to investigate and quantify the time-related changes in passive mechanics, volume, and fat of the infraspinatus muscle. We hypothesized that infraspinatus muscle stiffness would increase, volume would decrease, and fat content would increase at twelve weeks following tendon detachment. METHODS The right infraspinatus tendon of eight adult mongrel dogs were surgically detached from the proximal part of the humerus. The uninvolved left shoulder served as a control. Muscle volume changes were quantified with use of magnetic resonance imaging. At twelve weeks, the passive mechanical properties of the chronically detached and control muscles were determined intraoperatively with use of a custom-designed device. Intramuscular fat was evaluated histologically at the time that the animals were killed. RESULTS After twelve weeks of detachment, the stiffness was significantly increased in the detached infraspinatus muscles relative to that in the controls (p < 0.0001). Magnetic resonance image analysis demonstrated that the detached muscle volumes decreased by an average of 32% in the first six weeks and remained constant thereafter. Intramuscular fat increased significantly in the detached muscles and to a greater extent in the lateral regions (p < 0.05). CONCLUSIONS The chronically detached muscle is not merely a smaller version of the original muscle but, rather, a different muscle. The detached muscle becomes stiffer, and the passive loads required to repair it can become excessive. A significant reduction in muscle volume occurs within days to weeks following tendon detachment (p < 0.0001). The nonuniformity of changes in muscle fat suggests that fat content should be used cautiously as an indicator of muscle quality.

Abstract
BACKGROUND This paper describes the clinical management of four cases of shoulder impingement syndrome using a conservative multimodal treatment approach. CLINICAL FEATURES Four patients presented to a chiropractic clinic with chronic shoulder pain, tenderness in the shoulder region and a limited range of motion with pain and catching. After physical and orthopaedic examination a clinical diagnosis of shoulder impingement syndrome was reached. The four patients were admitted to a multi-modal treatment protocol including soft tissue therapy (ischaemic pressure and cross-friction massage), 7 minutes of phonophoresis (driving of medication into tissue with ultrasound) with 1% cortisone cream, diversified spinal and peripheral joint manipulation and rotator cuff and shoulder girdle muscle exercises. The outcome measures for the study were subjective/objective visual analogue pain scales (VAS), range of motion (goniometer) and return to normal daily, work and sporting activities. All four subjects at the end of the treatment protocol were symptom free with all outcome measures being normal. At 1 month follow up all patients continued to be symptom free with full range of motion and complete return to normal daily activities. CONCLUSION This case series demonstrates the potential benefit of a multimodal chiropractic protocol in resolving symptoms associated with a suspected clinical diagnosis of shoulder impingement syndrome.

Abstract
BACKGROUND Rotator cuff tear, a common shoulder injury, can lead to shoulder pain and functional loss. HYPOTHESIS Surgical repair of full-thickness rotator cuff tears using the mini-open surgical technique will improve shoulder function and health-related quality of life. STUDY DESIGN Cohort study. Level of evidence, 2. METHODS Patients with a full-thickness rotator cuff tear who underwent a mini-open repair were evaluated for (1) active shoulder range of motion preoperatively, and 6 months and 12 months postoperatively and (2) health-related quality of life preoperatively, 6 months postoperatively, and annually up to 5 years postoperatively. Satisfaction with the repair and return to work status were ascertained 1 year postoperatively. A subgroup analysis of tear size and patient age was also undertaken. RESULTS Of the subjects, 61 (73%) were men, and the average age was 53.2 ( +/- 9.9) years. According to repeated-measures analysis of variance, shoulder range of motion (flexion and external rotation) improved significantly from before surgery to 1 year after surgery (P <.001). The mean American Shoulder and Elbow Surgeons scores improved from 53.3 ( +/- 20.6) preoperatively to 90.6 ( +/- 11.7) 1 year postoperatively (P <.001). The mean Western Ontario Rotator Cuff scores also improved from 43.2 ( +/- 20.2) preoperatively to 87.2 ( +/- 14.3) 1 year postoperatively (P <.001). No differences were seen in either the American Shoulder and Elbow Surgeons scores or Western Ontario Rotator Cuff scores between the 1-year examination and the last follow-up assessment undertaken at a median of 5 years postoperatively (P >.05). Ninety-six percent of patients were satisfied or very satisfied with the results of their repair; 78% of patients who were working before surgery returned to work without modification by 1 year postoperatively. For the most part, patient age and size of tear did not influence postoperative range of motion or health-related quality of life. CONCLUSION Mini-open rotator cuff repair led to improved shoulder function and health-related quality of life up to 5 years postoperatively.

Lazaro R. Shoulder impingement syndromes: implications on physical therapy examination and intervention. JOURNAL OF THE JAPANESE PHYSICAL THERAPY ASSOCIATION 2005; 8:1-7. [PMID: 25792938 DOI: 10.1298/jjpta.8.1] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2003] [Accepted: 04/03/2004] [Indexed: 11/23/2022]
Abstract
A painful shoulder presents challenges in examination, diagnosis and intervention for the physical therapist because of the complexity of the structures involved. A common cause of shoulder pain is shoulder impingement syndrome. This was first described as a condition in which the soft tissues of the subacromial space were chronically entrapped and compressed between the humeral head and the subacromial arch. This definition does not account for the myriad potential causes of shoulder impingement conditions, as forms of impingement other than subacromial soft tissue compression may explain different symptomatic shoulder injuries. This paper describes shoulder impingement syndromes that have been hypothesized, identified and analyzed in the literature. Physical Therapy examination and intervention for these syndromes are also discussed.

Abstract
OBJECTIVE To present a case of shoulder impingement syndrome managed with a conservative multimodal treatment approach. CLINICAL FEATURES A patient had anterior shoulder pain and a diffuse ache in the right upper arm, with tenderness in the shoulder region on palpation. Shoulder range of motion was limited with pain and catching, coupled with limited and painful cervical motion. After physical and orthopedic examination, a clinical diagnosis of shoulder impingement syndrome was made. INTERVENTIONS AND OUTCOME The patient underwent a multimodal treatment protocol including soft tissue therapy, phonophoresis, diversified manipulation; and rotator cuff and shoulder girdle muscle exercises. Outcomes included pain measurement; range of motion of the shoulder, and return to normal daily, work, and sporting activities. At the end of the treatment protocol the patient was symptom free with all outcome measures normal. The patient was followed up at 4 and 12 weeks and continued to be symptom free with full range of motion and complete return to normal daily and pre-treatment activities. CONCLUSION This case report shows the potential benefit of a multimodal chiropractic protocol in resolving symptoms associated with shoulder impingement syndrome.

Abstract
This article reviews basic shoulder anatomy and biomechanics and discusses the impact these have on the etiology of shoulder injuries in sports. Four types of sport activities lead to shoulder injuries:muscle and tendon overuse, acute tears of the dynamic stabilizers,impingement and overuse injury. Most shoulder injuries initially are treated nonoperatively with rehabilitation. Rehabilitation protocols are successful in most patients. This article also discusses why postoperative rehabilitation is vital to the ultimate success of patients who require operative treatment.
