Effects of a Thoracic Manipulation on Hip Adductor, Extensor, and Latissimus Dorsi Force in Those With Adductor Weakness

Summary

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.

Conditions

• Muscle Weakness

Interventions

Type	Name	Description
PROCEDURE	High velocity low amplitude thoracic spine manipulation	Participants were supine on a treatment table. The chiropractor determined levels of apparent spinal dysfunction by means of static palpation. Participants were then asked to curl forward and bring their knees to their chest as the chiropractor placed a fist just inferior to the targeted level, anywhere between the T4 - T10 vertebrae. The participant was instructed to inhale and then exhale, at which point the chiropractor lowered the participant's torso back to the table and delivered a thrust using his body into his fist.
PROCEDURE	Sham	A previously validated physiologically inert manual procedure to the thoracic spine
