The impact of transcranial direct present stimulation on bilateral asymmetry and joint angles of the decrease limb for females when crossing obstacles | BMC Sports activities Science, Medication and Rehabilitation


Gait bilateral asymmetry decreased after tDCS throughout crossing greater obstacles

Gait bilateral asymmetry parameter values have been proven in Fig. 2. There have been no vital interplay between situation*top in left/proper Stride size GA (Fig. 2a) (all, P > 0.305) and left/proper DS time GA (Fig. 2d) (all, P > 0.278) between tDCS and sham-tDCS situation at 30%, 20%, 10% leg’s size impediment top. Nonetheless, left/proper Swing time GA (P = 0.046, P = 0.038, respectively), left/proper Stance time GA (all, P < 0.035), left/proper SW/ST GA (all, P < 0.005) confirmed vital variations between situation and top interplay results. Variations between sham-tDCS and tDCS circumstances in Swing time GA (Fig. 2b), Stance time GA (Fig. 2c) and SW/ST GA (Fig. 2e) at three impediment crossing heights have been discovered (all P < 0.05). In contrast with the sham-tDCS situation, the tDCS situation confirmed a considerably decreased in Swing time GA (Left: P30%=0.002, P20%=0.005, ES various from 0.71 to 0.80; Proper: P30%<0.001, P20%=0.002, ES various from 0.78 to 1.04, respectively), Stance time GA (Left: P30%=0.001, P20%=0.003, ES various from 0.76 to 0.83; Proper: P30%=0.002, P20%=0.003, ES various from 0.78 to 0.82, respectively) at 30% and 20% leg’s size impediment heights however not with 10% leg’s size. Particularly, the SW/ST GA (Left: P30%<0.001, P20%<0.001, P10%=0.021, ES various from 0.56 to 1.38; Proper: P30%<0.001, P20%<0.001, p10%=0.045, ES various from 0.48 to 1.40, respectively) of tDCS situation decreased considerably at 30%, 20% and 10% leg’s size impediment top.

(L: Left/R: Proper: left and proper limb, respectively, as main limb throughout impediment crossing; 30, 20, 10LL: 30%, 20% and 10% leg’s size obstacles top; SW: swing time, ST: stance time, SW/ST: swing/stance time, DS: double assist time, GA: gait asymmetry)

Most joint angles decreased after tDCS throughout crossing greater obstacles

Moreover, main and trailing limb most joint angles parameter values have been proven in Fig. 3, an interplay impact was discovered between situation*top in left/proper ankle (all, P < 0.025), left/proper hip (all, P < 0.033); left/proper knee (all, P < 0.048) of main limb, left/proper hip (all, P < 0.005), left/proper knee (all, P < 0.029) of trailing limb, nonetheless, no vital interplay impact between situation*top was discovered for left/proper ankle joint (Fig. 3b) when trailing limb crossed obstacles. Ankle joint angles (Fig. 3a), knee joint angles (Fig. 3c), hip joint angles (Fig. 3e) of main limb and knee joint angles (Fig. 3d), hip joint angles (Fig. 3f) of trailing limb confirmed variations compared sham-tDCS and tDCS situation. Particularly, ankle (Left: P30%=0.034, P20%=0.001, ES various from 0.51 to 0.89; Proper: P30%=0.036, P20%<0.001, ES various from 0.50 to 1.01, respectively), knee (Left: P30%<0.007, P20%<0.001, ES various from 0.67 to 1.18; Proper: P30%=0.001, P20%=0.001, ES various from 0.90 to 0.92, respectively), hip (Left: P30%<0.001, P20%=0.009, ES various from 0.65 to 1.34; Proper: P30%=0.001, P20%=0.002, ES various from 0.79 to 0.89, respectively) joint angles of main limb and knee (Left: P30%=0.001, P20%<0.001, ES various from 0.84 to 1.03; Proper: P30%<0.001, P20%<0.001, ES various from 0.99 to 1.05, respectively), hip (Left: P30%<0.001, P20%<0.001, ES various from 1.04 to 2.18; Proper: P30%<0.001, P20%<0.001, ES various from 1.27 to 1.49, respectively) joint angles of trailing limb in tDCS situation have been decrease than sham-tDCS situation at 30% and 20% leg’s size impediment top however excluding 10% leg’s size impediment top.
