Imagery Reduces Tremor in Parkinson’s Patients
Researchers from the Department of Neurology at Rambam Hospital in Haifa, Israel examined whether a Parkinson’s Disease (PD) tremor, known to worsen with stress, could improve with what they refer to as “relaxation guided imagery” (RGI) and calming music.
Twenty PD patients with moderate to severe tremor participated in sessions where relaxation techniques were implemented. Tremor was objectively monitored using an accelerometer.
All 20 subjects in the imagery condition (RGI) had dramatically decreased tremor (baseline 270.38 +/- 85.82 vs. RGI 35.57 +/- 43.90 movements per minute P < 0.0001). Additionally, in 15 patients, the tremor was completely gone for 1-13 min.
Average tremor activity remained significantly bellow baseline, both 15 min and 30 min after RGI was discontinued (P < 0.001). Patients reported improvement lasting 2-14 hours (mean 6.8 +/- 3.8).
Relaxing music significantly reduced the tremor, but to a lesser degree than RGI (220.04 +/- 106.53 movements per minute P = 0.01). And simple, self-relaxation had no significant effect on tremor.
The researchers conclude that RGI can supplement conventional medical treatments for tremor in patients with PD.
