Abstract
Objective: We examined the long-term effects of low-intensity electrical stimulation (ES) on (micro)vasculature and sitting pressure of a home-based, wearable ES device in a pilot feasibility study. Design: In a cohort observation before-after trial, 9 middle-aged male (n=8) and female (n=1) individuals (48±15 y) with ASIA A-C classified chronic (1-24y) SCI underwent 12-wk of self-administered daily, low-intensity gluteal and hamstring ES [50Hz, 6 hrs (30min ES, 15min rest)]. Common femoral artery (CFA) diameter and blood blow were determined with ultrasound, skin vascular function during local heating was assessed using Laser-Doppler flowmetry, thigh volume was estimated using leg circumferences and skinfolds, and interface sitting pressure was measured using pressure-mapping. Results: Resting CFA diameter increased (0.73±0.20 to 0.79±0.22cm, P<0.001), baseline CFA blood flow increased (0.28±0.12 to 0.40±0.15 L/min, P<0.002). Gluteal cutaneous vascular conductance showed a time*temperature interaction (P=0.01) with higher conductance at 42°C after 12 weeks. Ischial peak pressure decreased (P=0.003) by 32±23mmHg and pressure gradient decreased (23±7 to 16±6 mmHg, P=0.007). Thigh volume increased (+19%, P=0.01). Conclusion: Twelve weeks daily, home-based gluteal and hamstring ES is feasible and effective to improve (micro)vasculature and sitting pressure and ES may have clinical implications for ameliorating pressure ulcers and (micro)vascular complications in SCI.
