Table 1.

Estimated root-mean-squared EMG (µV) with bootstrapped 95% confidence intervals (CI) for the 50 ms preceding stimulation in each condition

	Test	Conditioning
AA	8.5 (CI 7.6–9.4)	19.9 (CI 17.0–22.8)
AR	30.3 (CI 25–35.8)	5.1 (CI 4.7–5.4)
RR	2.2 (CI 2.2–2.3)	3.7 (CI 3.5–3.9)

AA: both hands active; AR: test hand active; RR: both hands at rest. The ranges of resting and active muscle pre-EMG were non-overlapping
