Functional measurements of crushed tibialis anterior (TA) muscles. a Experimental design. b Organ bath studies of TA muscles after the crush injury. Twitch tension: single 0.5-ms square pulses at 40 Hz. Tetanic tension: series of 0.5 ms pulses for 300 ms at 40 V, 120 Hz. n = 10–11 per group. c Paired results for the samples measured from the same mice at 14 and 28 days postinjury. Paired t test, n = 10–11 per group. Results are normalized to the muscle weights. d TA average weight at 7, 14, and 28 days postinjury in comparison with the healthy muscle weight; n = 5–11 per group
