The Effects of Isolated Joint vs. Multiple Joint Training on the Shoulder

Authors: Jones, C, McGuire, E, Mettenburg, T, Hill, B, Henderson, N, Worst, H, Mans, K, Davies, GJMulti-joint (MJ) and isolated-joint (IJ) training are two strengthening techniques commonly used in rehabilitation as well as performance enhancement. The literature comparing IJ and MJ exercises is divided on which method is superior, and is focused more on the lower extremity than upper. The purpose of this study was to determine if there were any significant differences between these two forms of performance enhancement training in the upper extremity. We hypothesized that multiple joint training will have greater effects on the outcome measures compared to the isolated joint training.

The Single-Arm Seated Shot Put Test as a Functional Outcome Measure in Adults with Healthy and Painful Shoulders: Correlation between Isokinetic Peak Force and Shot Put Distance
The purpose of this study was to compare peak force (PF) of isokinetic closed kinetic chain (CKC) pushing at 0.24 m/s with distance of the single-arm seated shot put test (SSSPT) in subjects with healthy and painful shoulders to determine the clinical relevance of the SSSPT. Our hypothesis was there would be a correlation between the two tests in healthy and painful subjects.
Bilateral Comparison of Upper Extremity Peak Force During Isokinetic Closed Kinetic Chain Pushing in Adults with Healthy Shoulders

Authors: Morris, S, Pierce, MB, Putman, R, Thomas, L, Cowart, T, Henderson, N, Glenn, F, Riemann, BL, Davies, GJ

Isokinetic testing has been described as the gold standard for muscle testing. Upper extremity (UE) pushing is a common functional movement that has been assessed isokinetically with the closed kinetic chain (CKC) attachment for Biodex ® System Dynamometers. Existing literature comparing bilateral UE isokinetic CKC testing is scarce and shows inconsistent results. The purpose of this study was to determine if there is a bilateral difference in peak force (PF) during isokinetic CKC testing of the UE in adults with healthy shoulders. We hypothesized there would be ≤ 10% difference in PF bilaterally in adults with healthy shoulders when performing an isokinetic CKC pushing motion at 0.24 m/s.

Efficacy of a Computerized Shoulder Simulation Model on Developing Manual Therapy Skills in Physical Therapy Students

Authors: Altomare, C, Edwards, J, Godfrey, K, Hines, S, Bringman, D, Glenn, F, Henderson, N, Worst, H, Davies, GJMobilization techniques are an integral part of manual therapy implemented by physical therapists in the treatment of patients with various joint pathologies. It is important that Doctor of Physical Therapy students develop a competency in performing mobilizations accurately. The purpose of this study was to determine the efficacy of a computerized shoulder model (CSM) in the development of manual therapy skill retention and transference. We hypothesized the CSM would improve selected outcomes as an appropriate adjunct to classroom education of manual therapy training and the addition of clinical experience of second-year DPT students would enhance all outcomes. We also hypothesized training would improve skill retention on the CSM and skill transference of mobilization techniques to a computerized knee model (CKM).
