Influence of body weight unloading on mean muscle activity over gait cycle where a. Medial gastrocnemius (MG), b. Lateral gastrocnemius (LG), c. Rectus femoris (RF), d. Biceps femoris (BF) long head and e. Tibialis anterior (TA). Vertical bars represent the normalized mean values, error bars depict standard deviation between studies and dashed lines illustrate the result of linear regression for each category. Absence of error bar at a BWU level indicates that the data was available from only one study
