Stimulation patterns can be optimized by maximizing the force-time integral (FTI) per stimulation pulse of the elicited muscle contraction. Such patterns, providing the desired force output with the minimum number of pulses, may reduce muscle fatigue, which has been shown to correlate to the number of pulses delivered. Applications of electrical stimulation to use muscle as a controllable biologic...... hiện toàn bộ

Evaluation of force-sensing resistors for gait event detection to trigger electrical stimulation to improve walking in the child with cerebral palsyIEEE Transactions on Neural Systems and Rehabilitation Engineering - Tập 10 Số 1 - Trang 22-29 - 2002
B.T. Smith, D.J. Coiro, R. Finson, R.R. Betz, J. McCarthy
Force-sensing resistors (FSRs) were used to detect the transitions between five main phases of gait for the control of electrical stimulation (ES) while walking with seven children with spastic diplegia, cerebral palsy. The FSR positions within each child's insoles were customized based on plantar pressure profiles determined using a pressure-sensitive membrane array (Tekscan Inc., Boston, MA). Th...... hiện toàn bộ

Voice control of a powered wheelchairIEEE Transactions on Neural Systems and Rehabilitation Engineering - Tập 10 Số 2 - Trang 122-125 - 2002
R.C. Simpson, S.P. Levine
Several researchers have described voice control mechanisms for a power wheelchair, but voice control has yet to become a commercially viable control alternative. One problem with voice control is that the voice's limited bandwidth renders it impossible to make frequent small adjustments to the wheelchair's velocity. One possible solution is to utilize voice control in combination with the navigat...... hiện toàn bộ

Intraspinal micro stimulation generates locomotor-like and feedback-controlled movementsIEEE Transactions on Neural Systems and Rehabilitation Engineering - Tập 10 Số 1 - Trang 68-81 - 2002

Intraspinal microstimulation (ISMS) may provide a means for improving motor function in people suffering from spinal cord injuries, head trauma, or stroke. The goal of this study was to determine whether microstimulation of the mammalian spinal cord could generate locomotor-like stepping and feedback-controlled movements of the hindlimbs. Under pentobarbital anesthesia, 24 insulated microwires wer...... hiện toàn bộ
