Objective assessment of efficacy of electroacupuncture in the treatment of gait disorder in Parkinson’s disease

A report was just published to confirm the efficacy of electroacupuncture treatment on gait in patients with Parkinson’s, by using body-worn sensors, an objective monitoring device. The pilot study was published by journal PLOS one.

Parkinsonian gait is mainly characterized by general slow movement, in particular by a reduction of gait speed and stride length. The progressive nature of symptoms leads to the freezing of gait and falls. Parkinsonian gait tends to be difficult treated, as drug treatment and deep brain stimulation have limited efficacy. Acupuncture has been effectively used to relieve parkinsonian symptoms; however, its efficacy remains controversy.

Recently Dr. H Lei and colleagues in the United States conducted a clinical study by using wearable sensor technology, to objectively assess the efficacy of acupuncture treatment on gait in patients with Parkinson’s. PD patients were randomly allocated into real acupuncture group (n=10) and sham acupuncture group (n=5). In real group, electroacupuncture was applied on different acupoints on the scalp, body and limbs, for 30min, once a week for 3 weeks. In sham group, acupuncture needles were applied just under skin, ca 4mm at non-acupoints on the scalp, body and limbs without stimulation. The participants and assessors were masked to eliminate potential bias effect. Outcomes were monitored at baseline and after completion of treatments. Measurements included gait analysis perimeters. In addition, Unified Parkinson's Disease Rating Scale (UPDRS), short Falls Efficacy Scale-International (FES-I), and visual analog scale (VAS) for pain were utilized.

Results showed that electroacupuncture treatment statistically significantly improved gait symptoms judged by all gait objective measurements compared with sham acupuncture control group. In particular gait speed was markedly improved compared with sham control.

This was the first participants- and assessors- masked randomized control study that, using body-worn sensor technology to objectively assess potential benefits of EA in enhancing spatio-temporal parameters of gait in PD patients.
