Sensory approach to motion analysis

We measured mean amplitude (MA-EMG) and oscillation repetition rate (ORR-EMG) during dynamic and static exercises in clinical setting for the first time. We found that in healthy individuals, EMG amplitude depends on the nature of the exercises. The highest EMG amplitude was registered during static exercises. Patients with acute stroke primarily demonstrated low-amplitude EMG activity extended through the entire cycle of movement without a clear peak. Static exercises significantly improved the amplitude and frequency of EMG oscillations.
