Fig. 7From: Contribution of inter-muscular synchronization in the modulation of tremor intensity in Parkinson’s diseaseCorrelations between the pool-averaged coherence levels at tremor frequency and the tremor amplitudes in shoulder and elbow joints. Exponential regression results show that the tremor amplitudes in DOFs of a elbow flexion, c shoulder abduction, and d shoulder rotation are significantly correlated with the pool-averaged coherence level at tremor frequency, while that of b shoulder flexion isn’t. Different subjects are indicated with different markers and the error bars indicate the standard deviation of tremor amplitudes of each subjectBack to article page
