Previous studies have shown that peripheral muscles weakness or inhibition is related to spinal disorders. Passive mobilization and manipulation are likely to reverse such muscle weakness. The purpose of the study was to assess the effect of spinal mobilization on the maximal muscle strength of the hip flexors and motor function.
