Comparison of Balance Changes After Chiropractic Adjustments in Health Adults.

Not Applicable

Completed

• Conditions: Postural Balance; Musculoskeletal Manipulation
• Interventions: Other: Upper extremity manipulation

• Registration Number: NCT03877367
• Lead Sponsor: Parker University

Brief Summary

This study will examine the effect of upper and lower extremity manipulations on an upper extremity balancing task.

Detailed Description

Spinal manipulation has long been thought to have beneficial effects on posture, balance and proprioception; however, only a single study has investigated the effect of chiropractic treatment of the extremities on balance and posture. In a previous study, it was noted that lower extremity manipulation led to more ordered behavior on a dynamic, lower extremity balance task. It was also found that upper extremity manipulation led to less ordered behavior with same lower extremity balance task. Further studies are needed not only to validate this theory, but to further clarify the mechanism regarding specificity of manipulation to task.

Arm && Interventions

Group	Intervention	Description
Upper Extremity Group, Day 1	Upper extremity manipulation	Day 1: This group will receive a pre-test, upper extremity intervention, and post-test. Day 2: This group will receive a pre-test, lower extremity intervention, and post-test.
Lower Extremity Group, Day 2	Upper extremity manipulation	Day 1: This group will receive a pre-test, lower extremity intervention, and post-test. Day 2: This group will receive a pre-test, upper extremity intervention, and post-test.

Primary Outcome Measures

Name	Time	Method
Head Sensor to calculate angle of head inclination	30 seconds	There will be a sensor placed on each participant's head (in a neoprene headband), as well as on the midpoint of the tube. The head sensor will be used to calculate the angle of head inclination. The sensor on the tube will be used to calculate Sample Entropy as well as general kinematics.

Secondary Outcome Measures

Name	Time	Method
Ground reaction force	less than 1 minute	Participants will be standing on a force plate that will characterize their ground reaction forces, eyes open without tube (EONT) versus eyes closed without the tube (ECNT).
Center of pressure	less than 1 minute	Participants will be standing on a force plate that will characterize their center of pressure, EONT versus eye open with the tube horizontally (EOWT).
Velocity to measure sway.	less than 1 minute	Participants will be standing on a force plate that will characterize their velocity of sway, EOWT versus eye closed with tube held horizontally (ECWT).
Sway: measuring distance	less than 1 minute	Participants will be standing on a force plate that will characterize their distance of sway, EOWT versus ECWT.
acceleration to measure sway	less than 1 minute	Participants will be standing on a force plate that will characterize their acceleration of sway, EOWT versus ECWT.
