ABSTRACT
Objective:
To compare the rate of recruitment in two types of active straight leg raise (ASLR) and to investigate the activation patterns of the related muscles.Methods:
From June to October, 2018, eleven healthy subjects were recruited. Surface electromyography (sEMG) signals of unilateral rectus femoris, bilateral rectus abdominis, internal oblique abdominis, external oblique abdominis and multifidus were recorded in normal ASLR (Action A) and raising leg for ten seconds (Action B). %maximal voluntary isometric contraction (MVIC) of these muscles was processed and analyzed.Results:
%MVIC of ipsilateral internal oblique muscle and external oblique muscle were greater than the opposite side (t > 2.549, P < 0.05) in Action A; %MVIC of ipsilateral internal oblique muscle, external oblique muscle and rectus abdominis muscle were greater than the opposite side (t > 2.240, P < 0.05) in Action B; compared with action B, Action A had higher %MVIC of bilateral internal oblique and rectus femoris (t > 3.549, P < 0.05).Conclusion:
The activation mode of ipsilateral dominance was shown in both actions, and the different motion control strategies may be adopted by the neuromuscular system in different ASLR.
