Central Somatosensory Changes And Altered Muscle Synergies In Subjects With Anterior Cruciate Ligament Deficiency, Carol Courtney, Rose Marie Rine, Penny G. Kroll

Physical Therapy Faculty Research

To clarify the mechanisms of compensation in subjects with anterior cruciate ligament deficiency (ACL-D), we examined proprioception, quadriceps strength, somatosensory evoked potentials (SEPs) and muscle responses during gait in varied combinations of speed and incline. Seventeen subjects with ACL-D were grouped by functional level and report of giving way. Seven subjects without ACL-D served as a control sample for muscle response measures. ACL-D subjects with quadriceps weakness experienced giving way and could not resume sport activities. Those without weakness fell into one of two groups: (1) copers, who had full return to previous activity and no giving way despite proprioceptive …

Feasibility Of Electromyography-Triggered Neuromuscular Stimulation As An Adjunct To Constraint-Induced Movement Therapy, Stacy L. Fritz, Yi-Po Chiu, Matthew P. Malcolm, Tara S. Patterson, Kathye E. Light

Physical Therapy Faculty Research

Background and Purpose. The purpose of this case report is to explore the feasibility of electromyography-triggered neuromuscular stimulation (EMG-stim) as an adjunct to constraint-induced movement therapy (CIMT).

Case Description. The patient was a 72-year-old man, 10 years poststroke, who did not meet traditional CIMT criteria. The EMG-stim was applied to the wrist extensors of the patient's weaker arm for one half of the CIMT training hours.

Outcomes. The intervention was feasible for this individual. Improvements were observed in motor behavior, quality and amount of use, muscle activity, wrist range of motion, and reaction time of the more-affected extremity. These improvements …
