One week of textured insole wear is associated with improved plantar sensation and stride length in patients with Parkinson disease (PD), according to research from São Paulo State University in Brazil.
In 19 patients with PD, investigators assessed plantar sensation and gait before and after one week of wearing textured insoles. Plantar sensation was measured using Semmes-Weinstein monofilaments. Gait was assessed using an optoelectronic system as patients walked without insoles at a self-selected speed. The textured insoles featured half-sphere elevations in the distal phalanx of the hallux, heads of metatarsophalangeal joints, and heel.
After one week of insole wear, plantar sensation and stride length were significantly improved relative to baseline; the improvement in plantar sensation was maintained after another week of wearing conventional insoles.
The findings, which were epublished in September by Gait & Posture, suggest enhanced somatosensory feedback provided by the insoles results in improved gait-related motor output.
