The Muscle Shortening Maneuver (MSM) is derived from Feldman's λ model of motor control, and seems to induce a more balanced agonist- antagonist-muscular action. The hypothesized mechanism of action is a modulation of the Tonic Stretch Reflex Threshold (TSRT).

Abstract: Study investigated the mechanisms of action of the Muscle Shortening Maneuver (MSM), a noninvasive physical therapy approach that involves muscle shortening and solicitation in traction. The hypothesized mechanism of action is a modulation of the tonic stretch reflex thresholds (TSRTs). A secondary aim was to explore the implementation of the MSM as a stroke rehabilitation intervention to improve body functions and activities in individuals with limitations due to chronic stroke. Ten participants with chronic stroke were randomly assigned to MSM or conventional physical therapy (CPT) treatments. The TSRTs were assessed by the Montreal Spasticity Measure device. A selection of clinical and instrumental outcome measures assessed function and activity levels. Data were collected at baseline, end-of-treatment, and one month after the end-of-treatment. No adverse events were observed. In both between- and within-group post-treatment assessments, in the affected ankle the MSM group showed decreased TSRTs of the plantar flexor, increased strength of the dorsiflexor and active range of motion; also, the time needed to perform the Timed Up and Go test decreased. No changes were evident across assessments in the CPT group. The MSM seems able to modulate the TSRTs in individuals with stroke. Although with the limitations due to the pilot design, the variation in participants’ responses appears to be promising. Many methodological issues must be clarified and specified conceiving the progression toward a confirmatory trial.
