The Effect of Neuromuscular Electrical Stimulation (NMES) on EMG Coherence and Motor Unit Recruitment across Shoulder Muscles in Individuals with Rotator Cuff Disease
We are investigating the acute effects of NMES on EMG coherence and motor unit recruitment patterns across the shoulder muscles during various force levels and fatiguing contractions. This study will aid in developing new rehabilitation protocols with NMES that prioritize targeted neuromuscular control retraining, ultimately aiming to restore rotator cuff muscle functionality in people with shoulder pain.

The Effect of Neuromuscular Electrical Stimulation on Walking Performance in Older Adults.
Mobility affects older adult independence, physical activity, and quality of life. The aim of this study is to determine whether electrical stimulation of the calf muscles during walking attenuates the age-related distal-to-proximal redistribution in joint mechanics and metabolism. The results of this study will contribute to the development of walking rehabilitation protocols for older populations. (see flyer)

Effects of Subthreshold Vibrating Insoles on Dynamic Balance Control During Walking
Diabetic peripheral neuropathy is known to decrease feelings of sensation in the feet which are essential for balance. A possible way to improve sensation and balance for those with diabetic peripheral neuropathy includes using vibrating insoles. In the present study, we aim to determine the most optimal vibration intensity to improve dynamic balance control and will test dynamic balance by implementing perturbations mimicking real-life scenarios. The results of this study will help validate and contribute to the development of vibrating insoles to improve balance for those with diabetic peripheral neuropathy. (see flyer)

Balance Control in Older Adults with Diabetic Peripheral Neuropathy
Peripheral neuropathy is a common condition in the diabetes population affecting the lower leg and foot. This results in poor balance control leading to increased fall risk. We aim to identify the biomechanical and neuromuscular control mechanisms affected by peripheral neuropathy. Results of this study will help us develop treatment strategies to improve balance and decrease the risk of falling and consequently enhance the quality of life and life expectancy in old adults with diabetic peripheral neuropathy.
