The topic of muscle inhibition has been investigated for certain period of time, several causes have been proposed, including pain, joints mechanics, sensory and spinal dysfunction. However, the number of randomized controlled trials is not enough. The purpose of this study was to conduct a pilot study to find out if lumber mobilization reduces hip flexor muscle inhibition.
24 participants were qualified for the study. Participants were randomly divided into experimental group and control group. A handheld dynamometer was used to measure the hip flexor strength before and after a L2–3 joint mobilization or a placebo treatment.
The percentage change in torque was higher (p < 0.001) in the experimental group after the intervention. The results suggested that passive mobilization on L2–3 may increase the strength of hip flexor for people without active low back pain.
