Physical activity measured by accelerometry.

Variable	SHAM	NMES	P-value (n/n)
Pre-surgery (counts)	195,099 ± 29,299	205,704 ± 37,786	0.830 (9/10)
3 weeks post-surgery (counts)	124,027 ± 21,454	86,727 ± 14,578	0.155 (7/11)
Slope of physical activity counts from month 1 through month 5 post surgery (counts/month)	904 ± 221	987 ± 286	0.775 (7/9)

Data are mean ± SE. Units for accelerometry are raw activity counts Sample sizes are variable because of missing data, as detailed in the Results.
