This pilot, prospective clinical trial will use a randomized clinical trial design. The primary dependent variable is isometric muscle strength, measured in pounds, an interval level of measurement. Muscle strength will be determined by the maximum voluntary contraction (MVC) and measured by an electronic hand-held dynamometer. Hand-held dynamometric muscle testing has demonstrated good intrarater reliability and validity when compared to Biodex dynamometry. Although there is no established minimal clinically important change (MCID) score for strength testing, some authors have suggested a 10% change in strength to be clinically significant. Pain will be measured at the ordinal level with the numeric pain rating scale (NRPS). Investigators will recruit subjects from routine clinical practice within the NYULMC-CMC. The outcomes variables (isometric muscle strength and strength) will be measured before and after the intervention at the initial evaluation visit. After these measures are obtained, the participation in the study is complete. There is no follow-up.
