The levels of (A) knee extension strength and (B) fatigue resistance that were established from the reconditioning exercise program and standing training with the neuroprosthesis were maintained at the follow-up visit.

Maximum standing times remained relatively constant or decreased slightly when comparing the follow-up value with that at discharge.

5. Fig 4
Body weight distribution data were collected for 7 subjects at follow-up, but only 3 subjects had paired data at discharge. A trend of decreased body weight supported by the lower extremities was seen, but was not statistically significant from the discharge values.

The majority of both epimysial and IM electrodes were stable over time as supported by small threshold changes (<10μs) between the 2 intervals studied.

Kaplan-Meyer estimates of the probability of the device survival. At 30 months postsurgery, probability of survival was 93.0% for IRS-8s, 97.1% for IM electrodes, and 90.4% for epimysial electrodes.
