Preventative Measures to Reduce Incidence of Handcuff Neuropathy
Author(s): Geoffrey T Desmoulin*, Marc-André and Theodore E Milner
Neuropathy due to prolonged restraint in handcuffs remains a significant concern because handcuffs can be
inadvertently over tightened, placing excess pressure on the superficial radial nerve. Recent modifications in
handcuff design have begun to address this issue and warrant further investigation. It was hypothesized that a new
handcuff design, which prevented over tightening of handcuffs, would prevent the pressure applied to the superficial
radial nerve from exceeding nerve injury risk thresholds. To test this hypothesis we used a physical model of the wrist
and superficial radial nerve which allowed measurement of the pressure applied by tightened and artificially loaded
handcuffs. Three handcuff designs were tested, one of which was designed to prevent over tightening. Recorded
pressure was compared to pressure thresholds for loss of function of the rat tibi.. View more»
