Electrical Stimulation-Assisted Standing Rehabilitation for Individuals with Incomplete Spinal Cord Injury

We are testing the effect of FES-assisted sit-to-stand (STS) training on EMG activity of leg muscles (gluteus maximus, quadriceps, hamstrings, soleus, and tibialis anterior), standing balance parameters, and standardized test scores for motor function (FIM, WISCII). Patients with incomplete lower extremity paralysis will receive the 12-week STS training exercise with or without FES at the Brain & Spine Recovery Center, Seton Southwest Hospital and we will compare the improvement of EMG activity, balance during and after STS, and motor function between two training interventions before and after training program to evaluate the effects of FES-assisted STS training. (See flyer.)

Motor Control Scheme in Knee Degeneration

The knee (patellofemoral joint) is very critical and yet very fragile in the human motor system.  To maintain homeostasis within the joints, muscles that insert into the patella must be controlled in a manner that allows adequate sliding the femoral groove. With in-depth single motor unit recording, we investigate intermuscular balance and coordination of the muscles that serve thee knee in healthy younger and older adults and in those with anterior knee pain (patellofemoral pain syndrome). The findings of this study will contribute to clinical rehabilitation and prevention of knee pain. (see flyer for older and younger adults).

Effect of Electrical Stimulation on Post-stroke Hemiparetic Sit-to-Stand

Stroke survivors have very high risk of falling, especially during everyday transition, such as rising from a chair. Hemiparesis often occurs post-stroke and significantly contributes to reduced stability. Post-stroke patients require a longer time to stand from a seat. This reflects reduced task performance, stability, and coordination. In addition, they have reduced muscle activation delay on the paretic site. We aim to improve paretic muscle activation and timing using function electronic stimulation (FES) during the sit-to-stand task. The findings from this study will aid clinical rehabilitation of post-stroke patients, reduce falls risk and increase patient independence. (See flyer.)
