The American Society of Shoulder and Elbow Therapists' consensus statement on rehabilitation following arthroscopic rotator cuff repair.

This is a consensus statement on rehabilitation developed by the American Society of Shoulder and Elbow Therapists. The purpose of this statement is to aid clinical decision making during the rehabilitation of patients after arthroscopic rotator cuff repair. The overarching philosophy of rehabilitation is centered on the principle of the gradual application of controlled stresses to the healing rotator cuff repair with consideration of rotator cuff tear size, tissue quality, and patient variables. This statement describes a rehabilitation framework that includes a 2-week period of strict immobilization and a staged introduction of protected, passive range of motion during weeks 2-6 postoperatively, followed by restoration of active range of motion, and then progressive strengthening beginning at postoperative week 12. When appropriate, rehabilitation continues with a functional progression for return to athletic or demanding work activities. This document represents the first consensus rehabilitation statement developed by a multidisciplinary society of international rehabilitation professionals specifically for the postoperative care of patients after arthroscopic rotator cuff repair.

Physical Therapist Management of Glenohumeral Joint Osteoarthritis: A Clinical Practice Guideline from the American Physical Therapy Association.

A clinical practice guideline on glenohumeral joint osteoarthritis was developed by an American Physical Therapy Association volunteer guideline development group that consisted of physical therapists, an occupational therapist, and a physician. The guideline was based on systematic reviews of current scientific and clinical information and accepted approaches for physical therapist management of glenohumeral joint osteoarthritis. This clinical practice guideline is available in Spanish; see Supplementary Appendix 8.

Frozen shoulder: evidence and a proposed model guiding rehabilitation.

UNLABELLED: Frozen shoulder or adhesive capsulitis describes the common shoulder condition characterized by painful and limited active and passive range of motion. The etiology of frozen shoulder remains unclear; however, patients typically demonstrate a characteristic history, clinical presentation, and recovery. A classification schema is described, in which primary frozen shoulder and idiopathic adhesive capsulitis are considered identical and not associated with a systemic condition or history of injury. Secondary frozen shoulder is defined by 3 subcategories: systemic, extrinsic, and intrinsic. We also propose another classification system based on the patient's irritability level (low, moderate, and high), that we believe is helpful when making clinical decisions regarding rehabilitation intervention. Nonoperative interventions include patient education, modalities, stretching exercises, joint mobilization, and corticosteroid injections. Glenohumeral intra-articular corticosteroid injections, exercise, and joint mobilization all result in improved short- and long-term outcomes. However, there is strong evidence that glenohumeral intra-articular corticosteroid injections have a significantly greater 4- to 6-week beneficial effect compared to other forms of treatment. A rehabilitation model based on evidence and intervention strategies matched with irritability levels is proposed. Exercise and manual techniques are progressed as the patient's irritability reduces. Response to treatment is based on significant pain relief, improved satisfaction, and return of functional motion. Patients who do not respond or worsen should be referred for an intra-articular corticosteroid injection. Patients who have recalcitrant symptoms and disabling pain may respond to either standard or translational manipulation under anesthesia or arthroscopic release. LEVEL OF EVIDENCE: Level 5.

Spinal accessory nerve palsy: associated signs and symptoms.

STUDY DESIGN: Retrospective case series. BACKGROUND: Spinal accessory nerve palsy (SANP) is common following neck dissection surgery and can occur with blunt or penetrating trauma to the lateral neck region and cervical stretch injuries. Early detection of SANP remains a clinical challenge and the condition is often misdiagnosed. The purpose of this case series is to describe the associated history, signs, and symptoms related to SANP and increase awareness of the scapular flip sign as a clinical sign associated with SANP. CASE SERIES DESCRIPTION: Twenty subjects (13 male, 7 female) presented with pain and decreased shoulder function following head and neck surgery or posttrauma. All patients were thoroughly examined and the scapular flip sign was assessed. All patients presented with a cluster of signs and symptoms including trapezius atrophy, shoulder girdle depression, limited active shoulder abduction to less than 90 degrees , shoulder pain, and shoulder weakness. A positive scapular flip sign was present in all cases. The middle and lower trapezius were rated as 0/5, based on manual muscle testing, indicating no identifiable muscle activation against resistance. DISCUSSION: A typical history and consistent signs and symptoms were found related to SANP. A strong relationship appeared between the presence of the scapular flip sign and SANP. The suspected mechanism for the scapular flip sign is the unopposed pull of the humeral external rotators by the inactive middle and lower trapezius. Early identification of SANP can assist with the prognosis, explain persistent impairments and functional deficits, motivate appropriate diagnostic testing and interventions, and help maximize outcome. Further research to validate the scapular flip sign and establish a clinical prediction rule for the diagnosis of SANP should be performed.

The Penn shoulder score: reliability and validity.

STUDY DESIGN: Psychometric evaluation of a cross-sectional survey. OBJECTIVES: The purpose of this study was to examine the psychometric properties of reliability and validity of the Penn Shoulder Score (PSS). BACKGROUND: Shoulder outcome measures are used to assess patient self-report levels of pain, satisfaction, and function. The PSS is a 100-point shoulder-specific self-report questionnaire consisting of 3 subscales of pain, satisfaction, and function. This scale has been utilized in the literature. However, the measurement properties of reliability and validity, including responsiveness, of the PSS subscales and overall scale need to be established. METHODS AND MEASURES: Patients (n = 40) with shoulder disorders undergoing a course of outpatient physical therapy completed the PSS at initial visit and again within 72 hours to assess test-retest reliability. The Constant Shoulder Score (CSS) and the American Shoulder and Elbow Surgeons Shoulder Score (ASES) were also completed at the initial visit and compared to the PSS to assess convergent construct validity. A separate cohort of patients (n = 109) completed the PSS at initial visit and 4 weeks later. These scores were used to assess internal consistency and responsiveness. RESULTS: Reliability analysis revealed a test-retest ICC2,1 of 0.94 (95% CI, 0.89-0.97). Internal consistency analysis revealed a Cronbach alpha of 0.93. The standard error of measurement (SEM) was +/- 8.5 scale points (based on a 90% CI) and the minimal detectable change (MDC) was +/- 12.1 scale points (based on a 90% CI). The minimal clinically important difference (MCID) for improvement was 11.4 points. Pearson product moment correlation coefficients between the PSS and the CSS and ASES were 0.85 and 0.87, respectively. Responsiveness analysis revealed an effect size of 1.01 and a standardized response mean of 1.27. CONCLUSIONS: This study has demonstrated that the PSS is a reliable and valid measure for reporting outcome of patients with various shoulder disorders.

Rehabilitation after surgical management of the thrower's shoulder.

The overhead throwing motion is a complex and coordinated movement pattern involving the lower extremities, the trunk, and the upper extremity. Because of these tremendous demands on the shoulder, various shoulder injuries may occur. Two of the more common injuries to throwers are shoulder instability and superior labrum anterior-posterior lesions. Although nonoperative treatment is frequently successful in treating these conditions, surgical management may be necessary for the athlete to return to their sport. The purpose of this article is to review the first 3 phases of rehabilitation after arthroscopic capsular stabilization and superior labrum anterior-posterior debridement or repair. The fourth phase, return to throwing, will be covered in the final section.

Responsiveness of the numeric pain rating scale in patients with shoulder pain and the effect of surgical status.

CONTEXT: The Numeric Pain Rating Scale (NPRS) is commonly used to assess pain. Change in the NPRS across time can be interpreted with responsiveness indices. OBJECTIVE: To determine the minimal clinically important difference (MCID) of the NPRS. DESIGN: Single-group repeated measures. SETTING: Outpatient rehabilitation clinics. PATIENTS: Patients with shoulder pain (N = 136). MAIN OUTCOME MEASURES: At the initial evaluation patients completed the Penn Shoulder Score (PSS), which includes pain, satisfaction, and function sections. Pain was measured using an 11-point NPRS for 3 conditions of pain: at rest, with normal daily activities, and with strenuous activities. The NPRS average was calculated by averaging the NPRS scores for 3 conditions of pain. The final PSS was completed after 3-4 wk of rehabilitation. To determine the MCID for the NPRS average, the minimal detectible change of 8.6 points for the PSS function scale (0-60 points) was used as an external criterion anchor to classify patients as meaningfully improved (≥8.6 point change) or not improved (<8.6-point change). The MCID for the NPRS average was also determined for subgroups of surgical and nonsurgical patients. Cohen's effect sizes were calculated as a measure of group responsiveness for the NPRS average. RESULTS: Using a receiver-operating-characteristic analysis, the MCID for the average NPRS for all patients was 2.17, and it was 2.17 for both the surgical and nonsurgical subgroup: area-under-the-curve range .74-.76 (95%CI: .55-.95). The effect size for all patients was 1.84, and it was 1.51 and 1.94 for the surgical and nonsurgical groups, respectively. CONCLUSIONS: The NPRS average of 3 pain questions demonstrated responsiveness with an MCID of 2.17 in patients with shoulder pain receiving rehabilitation for 3-4 wk. The effect sizes indicated a large effect. However, responsiveness values are not static. Further research is indicated to assess responsiveness of the NPRS average in different types of patients with shoulder pain.

Short-term effects of high-intensity laser therapy versus ultrasound therapy in the treatment of people with subacromial impingement syndrome: a randomized clinical trial.

BACKGROUND: Subacromial impingement syndrome (SAIS) is a painful condition resulting from the entrapment of anatomical structures between the anteroinferior corner of the acromion and the greater tuberosity of the humerus. OBJECTIVE: The aim of this study was to evaluate the short-term effectiveness of high-intensity laser therapy (HILT) versus ultrasound (US) therapy in the treatment of SAIS. DESIGN: The study was designed as a randomized clinical trial. SETTING: The study was conducted in a university hospital. PATIENTS: Seventy patients with SAIS were randomly assigned to a HILT group or a US therapy group. INTERVENTION: Study participants received 10 treatment sessions of HILT or US therapy over a period of 2 consecutive weeks. MEASUREMENTS: Outcome measures were the Constant-Murley Scale (CMS), a visual analog scale (VAS), and the Simple Shoulder Test (SST). RESULTS: For the 70 study participants (42 women and 28 men; mean [SD] age=54.1 years [9.0]; mean [SD] VAS score at baseline=6.4 [1.7]), there were no between-group differences at baseline in VAS, CMS, and SST scores. At the end of the 2-week intervention, participants in the HILT group showed a significantly greater decrease in pain than participants in the US therapy group. Statistically significant differences in change in pain, articular movement, functionality, and muscle strength (force-generating capacity) (VAS, CMS, and SST scores) were observed after 10 treatment sessions from the baseline for participants in the HILT group compared with participants in the US therapy group. In particular, only the difference in change of VAS score between groups (1.65 points) surpassed the accepted minimal clinically important difference for this tool. LIMITATIONS: This study was limited by sample size, lack of a control or placebo group, and follow-up period. CONCLUSIONS: Participants diagnosed with SAIS showed greater reduction in pain and improvement in articular movement functionality and muscle strength of the affected shoulder after 10 treatment sessions of HILT than did participants receiving US therapy over a period of 2 consecutive weeks.
