Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Manipulation

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

Group Type EXPERIMENTAL

High velocity low amplitude thoracic spine manipulation

Intervention Type PROCEDURE

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.

Sham

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.

Group Type SHAM_COMPARATOR

Sham

Intervention Type PROCEDURE

A previously validated physiologically inert manual procedure to the thoracic spine
