Figure 3From: Fixed Dystonia in Complex Regional Pain Syndrome: a Descriptive and Computational Modeling Approach Model simulation results with normal reflexes. Joint angle (top panel) and muscle torques (bottom panel) at the wrist in response to external force (0-5 s) and voluntary contraction (10-15 s) with normal reflexes. In periods of rest (5-10 and 15-20 s) the muscle contractions subside and the hand returns to its neutral position.Back to article page
