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.)

Neuromuscular Control Patterns in Rotator Cuff Disease in Aged Adults

Identifiable shoulder disorders are very common in elderly adults. The aim of this study is to investigate neuromuscular control patterns of the rotator cuff and deltoid muscles in elderly adults aged over 65 years with and without shoulder pain. We will investigate differences during various force levels and fatigue tasks. The results of this study will contribute to developing mechanism-based treatment strategies for rotator cuff disease in the elderly. (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.
