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.

Effects of Aging of Muscle Activation Patterns and Postural Control During Sit-to-Stand With Different Initial Foot Positions

We are investigating the effects of different initial foot positions on balance and muscle activation patterns in the leg and trunk a during sit-to-stand (STS) in older adults and younger adults. (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).
