Table 4.
Comparison of Electromyographic Activity (%, M [SD]) of Upper Trapezius and Sternocleidomastoid Muscles During Activity Between Individuals With and Without Forward Head Posture
| Muscle | With FHP (n = 22) | Without FHP (n = 22) | Mean Difference (95% CI) | P |
|---|---|---|---|---|
| Right UT | 72.1 (4.47) | 53 (5.89) | 19.10 (16.01, 22.19) | .01* |
| Left UT | 74.8 (4.37) | 56.4 (0.45) | 18.40 (15.34, 21.46) | .01* |
| Right SCM | 83.6 (3.90) | 58 (0.15) | 25.60 (23.97, 27.23) | .01* |
| Left SCM | 75.8 (4.37) | 56.4 (0.45) | 19.40 (17.56, 21.24) | .01* |
CI, confidence interval; FHP, forward head posture; SCM, sternocleidomastoid; UT, upper trapezius.
