https://www.selleckchem.com/products/OSI-906.html Tendon transfer surgery restores function by rerouting working muscle-tendon units to replace the function of injured or paralyzed muscles. This procedure requires mobilizing a donor muscle relative to its surrounding myofascial connections, which improves the muscle's new line of action and increases excursion. However, the biomechanical effect of mobilization on a donor muscle's force-generating function has not been previously studied under invivo conditions. The purpose of this study was to quantify the effect of surgical mobilization on active and passive biomechanical properties of 3 large rabbit hind limb muscles. Myofascial connections were mobilized stepwise from the distal end to the proximal end of muscles (0%, 25%, 50%, and 75% of muscle length) and their active and passive length-tension curves were measured after each degree of mobilization. Second toe extensor, a short-fibered muscle, exhibited a 30% decline in peak stress and 70% decline in passive stress, whereas extensor digitorum longelf alters the passive and active force-generating capacity of skeletal muscles. Thus, surgical mobilization should not be viewed simply as a method to redirect the line of action of a donor muscle because this procedure has an impact on the functional properties of the donor muscle itself. Our primary purpose was to evaluate the reliability of telephone administration of the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Computer Adaptive Test (CAT) version 2.0 in a hand and upper extremity population, and secondarily to make comparisons with the abbreviated version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH). Patients more than 1 year out from hand surgeries performed at a single tertiary institution were enrolled. Half of the patients completed telephone PROMIS UE CAT and QuickDASH surveys first, followed by computer-based surveys 1 to 10 days later, and the
