Objective: Describe potential changes in parkinsonian rigidity after an administration of cooling intervention.Methods: Two patients with Parkinson’s Disease (PD) participated in the study that applied the forearm cooling intervention and objectively evaluated rigidity at the wrist joint through a cycle of passive flexion and extension movements of ±45° at a velocity of 50°/sec. Both patients underwent a baseline assessment (Pretest), and an immediate assessment after cooling intervention (Posttest) and 30 minutes after the cooling (30-min Posttest). Rigidity temporal score (Nm-sec) and work score (Nm-deg) were used to quantify and compare rigidity between the Pretest and the Posttests.Results: In Case #1, there were reductions in both rigidity scores at Posttest and relatively smaller reductions at 30-min Posttest after cooling. Case 2 demonstrated a slight increase immediately posttest which was followed with a slight decrease at 30-min Posttest.Discussion and
Conclusion: Cooling intervention appears to be a promising therapy in treating parkinsonian rigidity. Future research on a larger sample size is warranted for further investigation of the effectiveness of cooling therapy.
