Effects of a High Velocity Low Amplitude Mid-Thoracic Spinal Segment Manipulation on the Force Output of the Hip Adductors and Extensors and the Latissimus Dorsi in Healthy Individuals With Unilateral Hip Adductor Weakness
Effects of a High Velocity Low Amplitude Mid-Thoracic Spinal Segment Manipulation on the Force Output of the Hip Adductors and Extensors and the Latissimus Dorsi in Healthy Individuals With Unilateral Hip Adductor Weakness
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.
