Previous measurements of equal-sensation contours for electrocutaneous stimuli consisting of repeated bursts of biphasic pulses have shown that stimulus frequency has little effect on perceived amplitude, and that stimulus amplitude has no effect on

C5 and C6 quadriplegic individuals lack motor and sensory function in their hands. Hand grasp can be partially restored using functional neuromuscular stimulation, but controlling the synthesized grasp is hindered by the absence of tactile or proprio

The ability of subjects to detect temporal gaps between bursts of sinusoids or bursts of bandlimited noise was measured to evaluate the phenomenon of tactile ‘‘sensory persistence’’ in older persons. Vibratory stimuli were delivered to the ri

Several previous investigations have measured accelerating psychophysical functions for perceived force with exponents of about 1.7. Two halving and doubling experiments presented here imply a psychophysical function for perceived force with an expon

We developed a quantitative grasp and release test for assessing a hand neuroprosthesis in C5 and C6 level tetraplegic patients. The objectives were (1) to determine if a patient's hand performance with the neuroprosthesis exceeded a defined, clinica

Six subjects made cross-modal matches of pinch force and bite force to an electrocutaneous stimulus. The electrocutaneous stimulus consisted of bursts of pulses, and the intensity of the stimulus was varied by changing the number of pulses per burst.

Detection thresholds were measured for sinusoidal vibrations applied to the thenar eminence and volar forearm. Stimuli were applied via a 0.72‐cm2 circular contactor, with and without a rigid surround. At low frequencies, below about 40 Hz, the thr

Threshold shifts for the detection of vibrotactile test stimuli were determined as a function of the intensity of a masker. The masking stimulus, narrow‐band noise centered at 275 Hz, and the test stimulus, a 15‐, 50‐, 80‐, or 300‐Hz sinuso

A tactile stimulator array constructed from 88 piezoelectric ceramic plates is described. The array can produce sinusoidal traveling waves with arbitrary temporal frequency, spatial wavelength, and amplitude. Detection thresholds were measured for fi
