The influence of local pain on balance control in patients with chronic ankle instability

Table 4 The root mean square (RMS_EMG) values of tibialis anterior, peroneus longus, soleus and medial gastrocnemius, muscles of the two groups

RMS_EMG	Group A (n = 12)	Group B (n = 14)	P value
Tibialis anterior (mV)	0.050 (0.015)	0.069 (0.048)	0.162
Peroneus longus (mV)	0.122 (0.057)	0.181 (0.078)	0.039
Soleus (mV)	0.056 (0.014)	0.085 (0.037)	0.018
Medial gastrocnemius (mV)	0.079 (0.036)	0.089 (0.031)	0.425

Group A: pain-free CAI; group B: pain-present CAI
Parameters are presented as mean (SD)
Abbreviations: CAI Chronic ankle instability, RMS_EMG mean root mean square of electromyography
