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.
