Effect of Brief Daily Resistance Training on Occupational Neck/Shoulder Muscle Activity in Office Workers with Chronic Pain: Randomized Controlled Trial

Table 6

Duration of each EMG gap (seconds) under 0.5% EMGmax for m. trapezius and m. splenius, median (interquartile range).

		Training (𝑁=15)	Control (𝑁=15)
Trapezius
Before daily training session	Week 0	0.72 (0.6–1.74)	0.9 (0.54–1.68)
	Week 10	1.26 (0.6–1.98)^b	0.6 (0.42–1.02)
After daily training session	Week 0	1.08 (0.66–1.8)	0.96 (0.6–1.38)
	Week 10	1.56 (0.72–2.76)	0.78 (0.36–1.26)
Splenius
Before daily training session	Week 0	0.42 (0.36–0.48)	0.6 (0.48–0.96)
	Week 10	0.72 (0.54–0.78)^a	0.36 (0.3–0.48)
After daily training session	Week 0	0.54 (0.42–0.6)	0.54 (0.42–0.72)
	Week 10	0.72 (0.54–1.02)	0.48 (0.42–0.54)
