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

Wrist Robot-Assisted Rehabilitation Treatment in Subacute and Chronic Stroke Patients: From Distal-to-Proximal Motor RecoveryIEEE Transactions on Neural Systems and Rehabilitation Engineering - Tập 26 Số 9 - Trang 1889-1896 - 2018
Stefano Mazzoleni, Vi-Do Tran, Paolo Dario, Federico Posteraro
In this paper, the recovery of proximal and distal segments in stroke patients who received distal training alone was investigated. Forty (20 subacute and 20 chronic) stroke patients were recruited to perform wrist robot-assisted rehabilitation training. The upper extremity, shoulder-elbow, and wrist subsections of the Fugl-Meyer assessment scale were used to assess the motor recovery of distal an...... 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). 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
