Abstract

Background Ability of balance maintenance and postural control is important to prevent falling and injuries when balance perturbations occurs during walking. Injuries due to unloading of the base of support in walking and running such as ankle sprain has high incidence. Poor muscle function may put the joint in unstable condition. The association of the unloading and poor muscle function in the ankle joint may increase the rate and the intensity of the ankle sprain. Various techniques have been applied to maximize the joint’s stability. The objectives of this study was to compare the effects of general warming, local warming and taping of the ankle joint on the electrical activity of few muscles during a sudden unloading of the base of support during walking.

Highlights

Ability of balance maintenance and postural control is important to prevent falling and injuries when balance perturbations occurs during walking
Using Biometrics Datalog EMG system with eight bipolar surface electrodes the electrical activity of medial gastrcnemious (MG), proneus longus (PL), vastus medialis (VM) and erector spina at L3 l3v3l (ESL3) muscles were recorded by 1500HZ sampling frequency
In general unloading resulted in higher EMG amplitude of muscles
