Trial Summary

What is the purpose of this trial?

The goal of this trial was to determine if a mid-thoracic high velocity low amplitude spinal manipulation improves force output in those with unilateral hip adductor weakness. The main aims were to determine if the intervention: Improved hip adductor force and muscle activation immediately and 48 h post manipulation compared to a control group. Improved gluteus maximus and latissimus dorsi force and muscle activation immediately and 48 h post manipulation compared to a control group. Strength and muscle activation of the hip adductors, hip extensors (gluteus maximus), and shoulder extensors (latissimus dorsi) were measured prior to, immediate after, and 48 hours after receiving a high velocity low amplitude manipulation to the thoracic spine. The manipulation was performed by a licensed chiropractor. A control group received a validated sham manipulation to the thoracic spine. Participants were blinded to group assignment.

Placebo Group

Group I: ManipulationExperimental Treatment1 Intervention

Those in the intervention group received a high velocity low amplitude manipulation to the mid-thoracic spine provided by a licensed chiropractor.

Group II: ShamPlacebo Group1 Intervention

Those in the control group received a validated sham manipulation to the mid-thoracic spine. The sham manipulation was done so that there was minimal downward force applied to the spine.
