Assessing the effectiveness of EMG-biofeedback on an isometric strengthening program in individuals with multiple sclerosis.

The purpose of this randomized controlled experiment was to assess the efficacy of electromyographic biofeedback as an adjunct treatment to isometric exercise in MS patients. 20 patients took part in the research. Patients were randomly assigned to one of two groups: biofeedback (n = 10) or control (n = 10).

Synchronous Muscle Synergy Evaluation of Jaw Muscle Activities during Chewing at Different Speeds, a Preliminary Study.

Human mastication is a complex and rhythmic biomechanical process regulated by the central nervous system (CNS). Muscle synergies are a group of motor primitives that the CNS may combine to simplify motor control in human movement. This study aimed to apply the non-negative matrix factorization approach to examine the coordination of the masticatory muscles on both sides during chewing.
