|a Incidence of falls in lower extremity amputees is significant, in part due to loss of proprioceptive signals from the missing foot. Loss of the stretch reflex to the residual anterior tibial (AT) muscle also results in disuse atrophy. By stimulating the residual AT muscle during swing phase of gait, this study used functional electrical stimulation (FES) to determine the effects of 12 weeks (3 hours daily) of sensory feedback on confidence, gait, balance, and residual limb girth of a female traumatic transtibial amputee, age 30. Pre-and post-testing included an Activities-Specific Confidence (ABC) scale, limb girth measurements, one- and two-leg balance trials, and gait trials with and without FES. Standard deviations (SD) of the center of pressure (COP) in the x and y directions, cadence, velocity, and symmetry of step length (SLS=shortest step length [SSL]/longest step length [LSD]), stance time (STS=involved side [IS]/non-involved side [NIS]) and knee (KFS=IS/NIS) and hip (HFS=IS/NIS) flexion were collected using a single force plate and 3D video gait analysis system. Limb girth symmetry at the distal stump increased 1.26%. Gait pre-and post-testing with FES values (respectively) showed improvement in SLS (5.34%, 6.59%) while others improved (+) or worsened (-) when compared to 100% as perfect symmetry. These were: cadence (+1.03%, -2.0%), velocity (+3.5%, -3.33%), STS (+11.47%, -4.74%), KFS (-2.28%, +1.93%), and HFS (-8.98, +12.66). COP SDx, all stances, and SDy, single stance, were increased, indicating lower balance scores. Confidence scores increased in 7 of 16 activities. We suggest that FES sessions 3 hours/day for 12 weeks is not adequate to significantly influence stump atrophy or confidence, but there is a trend toward improvement in all variables excepting balance. Future studies should include a larger subject pool over a longer time period. |
