RESUMO
PURPOSE: To perform a review of the literature focusing on rehabilitation protocols in patients with acromioclavicular (AC) joint injuries treated operatively and nonoperatively and to provide an updated rehabilitation treatment algorithm. METHODS: Studies were identified by searching the MEDLINE database from 01/1995 to 09/2020. Included studies contained detailed rehabilitation protocols with physiologic rationale for AC joint injuries. Biomechanical studies, technique articles, radiographic studies, systematic reviews, case studies, editorials, and studies that compared nonoperative versus operative treatment without focus on rehabilitation were excluded. Following identification of the literature, an updated treatment algorithm was created. RESULTS: The search strategy yielded 1742 studies, of which 1654 studies were excluded based on title, 60 on the abstract, and 25 on the full manuscript. One study was manually identified using article reference lists, yielding four publications presenting detailed rehabilitation protocols based on physiologic rationale. No randomized controlled trials or comparative studies were identified or cited as a basis for these rehabilitation protocols. CONCLUSION: Few detailed rehabilitation protocols in patients with AC joint injuries have been published. These protocols are limited by their standardization, arbitrary timelines, and provide minimal assessment of individual patient characteristics. The quality of patient care can be improved with more practical guidelines that are goal-oriented and allow for critical thinking among clinicians to address individual patient needs. Three common barriers preventing successful rehabilitation were identified and addressed: Pain, Apprehension, and (anterior chest wall) Stiffness to regain Scapular control, effectively termed "PASS" for AC joint rehabilitation. CLINICAL RELEVANCE: Rehabilitation protocols for AC joint injuries should be less formulaic and instead allow for critical thinking and effective communication among clinicians and therapists to address individual patient needs.
RESUMO
INTRODUCTION: Patients undergoing a Reverse Total Shoulder Arthroplasty (RTSA) often have functional limitations that affect the range of motion of the shoulder. These limitations are not mechanical in nature, but instead linked to a reduced ability to generate muscle force. The specific aims of this study was to offer a comparison between the muscle activity generated by a post-operative RTSA shoulder in a patient to that of their contralateral shoulder during a series of functional activities. MATERIAL & METHODS: A convenience sample of 10 subjects between the ages of 50-75 years of age were recruited. EMG and kinematic data were concomitantly collected while subjects completed tasks that included common activities of daily living. RESULTS: The main findings of this study were that all sub regions of the deltoid functioned as abductors, versus the native shoulder where the middle deltoid primarily works in abduction. For the scapular elevation activity there was a significant difference in flexion between the surgical and contralateral shoulder (p < .001), with the surgical shoulder having nearly 30° less range of motion. CONCLUSION: Anticipating limitations in functional outcomes and range of motion for patients after RTSA may inform patient decision-making and improve clinical evaluations. The finding of increased mid deltoid function during lifting activity has implications for rehabilitation and encouraging protocols that strengthen the deltoid in concentric motions. Additionally, the decreased scapular elevation found in this study may guide rehabilitation focusing on regaining range of motion post-operatively.
RESUMO
PURPOSE: To compare the effect of early versus delayed motion protocols on quality of life, clinical outcomes, and repair integrity in patients who have undergone arthroscopic single-tendon rotator cuff repair. METHODS: This was a prospective, randomized, investigator-blinded clinical trial. Seventy-three patients from a single surgeon's practice who underwent arthroscopic repair of a single-tendon rotator cuff tear were randomized to either an early motion protocol (starting 2 to 3 days after surgery) or a delayed motion protocol (starting 28 days after surgery). The primary outcome measure was the Western Ontario Rotator Cuff index (WORC). Secondary outcome measures included clinical outcome scores, integrity of the repair on 6-month magnetic resonance imaging scans, pain scores, physical examination data, and ultrasonography. Study participants were followed up at 3, 6, and 12 weeks; 6 months; and 1 year postoperatively. RESULTS: There was no statistically significant difference in WORC scores at 6 months (529 ± 472 in delayed group vs 325 ± 400 in early group, P = .08). Mixed-effects analysis indicated the early group maintained lower WORC scores throughout the postoperative period (estimated difference of 191, P = .04). The proportions of patients with tears on the 6-month postoperative magnetic resonance imaging scan were comparable (31% in delayed group vs 34% in early group, P = .78). CONCLUSIONS: There was no difference between the delayed and early motion groups in WORC scores at 6 months after surgery. Early motion was associated with lower WORC scores throughout the postoperative period; however, both groups had a similar trajectory of improvement, suggesting both protocols have the same effect on patient-reported improvement. Although failure rates were similar between the groups, the sample size was not sufficient to support a statement regarding the relation between tear morphology and the rehabilitation protocol. LEVEL OF EVIDENCE: Level II, lesser-quality randomized controlled trial.

Acromioclavicular joint (AC) separations are one of the most common injuries seen in orthopedic and sports medicine practices, accounting for 9% of all injuries to the shoulder girdle. Various operative and nonoperative treatment schemes have been described for the management of AC joint injuries. Although there is controversy about the efficacy of surgical reconstruction versus nonoperative intervention for grade III type injuries, grade I and II separations seem to respond favorably to conservative management. Conversely, grades IV, V, and VI often require surgical reconstruction. Regardless of the type of injury, rehabilitation as a part of conservative management and postoperative care plays an important role in the management of these injuries. This article presents a rehabilitation approach to treatment of acromioclavicular separations pre- and postoperatively.

HYPOTHESIS: The performance of scapular exercises in the context of a clinical model of fatigue will result in superior migration of the humeral head and alterations in shoulder kinematics on radiographic analysis. MATERIALS AND METHODS: Six healthy male volunteers underwent a series of radiographs before and immediately following two scapular exercises. To reproduce a practice setting a clinical model of muscle fatigue was utilized. Radiographs were taken at various degrees of elevation. Glenohumeral angle (GA), scapulothoracic angle (SA), and the position of the humeral head on the glenoid (excursion) were measured on each radiograph. Two-tailed paired sample t-test were used to compare pre-fatigue to post fatigue measures. RESULTS: Following fatigue there was a significant increase in excursion at 45, 90, and 135 degrees of elevation indicating superior migration of the humeral head. There was an increase in SA from 0 to 45 degrees and a decrease in GA from 45 to 90 degrees of elevation. From 90 to 135 degrees an increase in GA was observed. DISCUSSION: The amount of superior migration of the humeral head observed following exercise was consistent with previously reported amounts of superior migration in patients with subacromial impingement. The alterations that occurred in shoulder kinematics following exercise may have resulted from parascapular muscle fatigue as well as rotator cuff muscle insufficiency. CONCLUSION: In the context of a clinical model of fatigue, these scapular exercises resulted in superior migration of the humeral head and alterations in shoulder kinematics on radiographic analysis in healthy subjects. LEVEL OF EVIDENCE: Basic science study.
