Table 3.
Comparison of Electromyographic Activity (%, M [SD]) of Upper Trapezius and Sternocleidomastoid Muscles During Rest Between Individuals With and Without Forward Head Posture
| Muscle | With FHP (n = 22) | Without FHP (n = 22) | Mean Difference (95% CI) | P |
|---|---|---|---|---|
| Right UT | 2.4 (0.83) | 1.4 (1.16) | 1.00 (0.40, 1.60) | .002* |
| Left UT | 2.6 (0.79) | 1.9 (0.73) | 0.70 (0.11, 1.29) | .007* |
| Right SCM | 2.2 (0.40) | 1.7 (1.00) | 0.50 (0.15, 0.85) | .04* |
| Left SCM | 2.4 (0.83) | 1.9 (0.96) | 0.50 (−0.03, 1.03) | .04* |
CI, confidence interval; FHP, forward head posture; SCM, sternocleidomastoid; UT, upper trapezius.
*Significant difference between groups.
