Does Passive Spinal Mobilization Improve Lower Limbs Strength and Function

February 23, 2016 updated by: LO CHI NGAI, The Hong Kong Polytechnic University
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.
