P1096 - Evaluating Effects of Global Proprioceptive Resonance on Gait in Multiple Sclerosis with Kinetic and Electromyography (ID 1871)
Abstract
Background
Global proprioceptive resonance (GPR) mechanically induces multifocal vibration at specific frequency among various cutaneous mechanoreceptors. Preliminary results suggest that GPR can modulate neuromuscular and neuroendocrine systems, therefore it may improve muscle strength and facilitate Lactose metabolism. Therefore, GPR could be beneficial for patients with multiple sclerosis (PwMS) since muscle weakness is an important factor of their gait impairment.
Objectives
Here we evaluated the acute effects of a single GPR session on gait pattern in patients with MS using wearable sensors to quantitatively measure surface electromyography (sEMG) and body acceleration during walking.
Methods
Ten patients with MS(PwMS, 8 males; mean age: 48±9.1 years; mean EDSS: 5.9±0.74), in a randomized order, underwent 15 minutes GPR and sham session(Keope GPR, ANDROMEDA, Italy) with a week interval. Nine Hole Peg Test(9HPT) and 6-meter-walking-test(SMWT) were performed pre- and immediately after the sessions. During SMWT, surface EMG and body acceleration were recorded with a wearable accelerator and surface electrodes(BTS Bioengineering, Italy). The SMWT were performed with spontaneous(Vp) and maximum velocity(Vmax). Time of 9HPT, velocity, cadence, step length and Coactivation index(CoI) of MWT of pre- and post-GPR were calculated for further statistics.
Results
Compared with sham stimulus, significant improvement was found in 9HPT(p=.02) of the dominant hand after the active GPR session. For SMWT, increased velocity(p = .05) and cadence(p =.03) after active stimulus was found under Vp condition only, but not in the Vmax condition. No significant difference was found in other parameters.
Conclusions
Our preliminary results suggest that a single active GPR session can improve the motor performance in both upper and lower limbs. Our results suggest that GPR could boost muscle recovery and can be beneficial to be incorporated into rehabilitation protocols to ameliorate the fatigue level for PwMS.
