RESUMEN
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.

BACKGROUND: Quality of cardiopulmonary resuscitation (CPR) is a key determinant of outcome following out-of-hospital cardiac arrest (OHCA). Recent evidence shows manual chest compressions are typically too shallow, interruptions are frequent and prolonged, and incomplete release between compressions is common. Mechanical chest compression systems have been developed as adjuncts for CPR but interruption of CPR during their use is not well documented. AIM: Analyze interruptions of CPR during application and use of the LUCAS™ chest compression system. METHODS: 54 LUCAS 1 devices operated on compressed air, deployed in 3 major US emergency medical services systems, were used to treat patients with OHCA. Electrocardiogram and transthoracic impedance data from defibrillator/monitors were analyzed to evaluate timing of CPR. Separately, providers estimated their CPR interruption time during application of LUCAS, for comparison to measured application time. RESULTS: In the 32 cases analyzed, compressions were paused a median of 32.5s (IQR 25-61) to apply LUCAS. Providers' estimates correlated poorly with measured pause length; pauses were often more than twice as long as estimated. The average device compression rate was 104/min (SD 4) and the average compression fraction (percent of time compressions were occurring) during mechanical CPR was 0.88 (SD 0.09). CONCLUSIONS: Interruptions in chest compressions to apply LUCAS can be <20s but are often much longer, and users do not perceive pause time accurately. Therefore, we recommend better training on application technique, and implementation of systems using impedance data to give users objective feedback on their mechanical chest compression device use.

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.
