Comparison of muscle activity and strength depending on neck rotation directions

Variable Neck rotating directions F p

Ipsilateral Neutral Contralateral
Biceps M (%MVIC) 73.82±18.53 78.44±16.04 78.96±16.21*† 7.35 0.002
Triceps M (%MVIC) 24.83±20.80 27.01±24.28 27.05±24.08 1.71 0.197
Elbow flexor strength (lbs) 28.84±8.83 30.85±10.75 31.39±11.88*† 7.54 0.002

Mean±SD: Mean±Standard Deviation, Biceps m: Biceps brachii muscle activity, Triceps m: Triceps brachii muscle activity.

*p<0.05: significant difference between neutral and contralateral neck rotation, p<0.05: significant difference between ipsilateral and contralateral neck rotation.
