The optimal stimulation pattern for skeletal muscle is dependent on muscle lengthIEEE Transactions on Neural Systems and Rehabilitation Engineering - Tập 10 Số 2 - Trang 85-93 - 2002

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

A predictive fatigue model. II. Predicting the effect of resting times on fatigueIEEE Transactions on Neural Systems and Rehabilitation Engineering - Tập 10 Số 1 - Trang 59-67 - 2002
Jun Ding, A.S. Wexler, S.A. Binder-Macleod
For pt. I see ibid., vol. 10, no. 1, p. 48-58 (2002). We have recently developed
a force- and fatigue-model system that accurately predicted the effect of
stimulation frequency on muscle fatigue (see pt. I). The data used to test the
model were produced by stimulation trains with resting times of 500 ms. Because
the resting times between stimulation trains affect muscle fatigue, this study
tested ... 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).

EEG Peak Detection in Cognitive Conflict Processing Using Summit Navigator and Clustering-Based RankingIEEE Transactions on Neural Systems and Rehabilitation Engineering - Tập 30 - Trang 1548-1556 - 2022
Tran Hiep Dinh, Avinash Kumar Singh, Nguyen Linh Trung, Diep N. Nguyen, Chin-Teng Lin
Correct detection of peaks in electroencephalogram (EEG) signals is of essence
due to the significant correlation of those potentials with cognitive
performance and disorders. This paper proposes a novel and non-parametric
approach to detect prediction error negativity (PEN) in cognitive conflict
processing. The PEN candidates are first located from the input signal via an
adaptation of a recent e... 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
