The Effects of Chiropractic in Adults With Metabolic Syndrome

Not Applicable

Suspended

• Conditions: Metabolic Syndrome
• Interventions: Procedure: Chiropractic adjustment

• Registration Number: NCT05884437
• Lead Sponsor: Life University

Brief Summary

The purpose of this study is to assess the feasibility of our study procedures/protocols and to look at the potential effects of chiropractic care on people with metabolic syndrome.

Detailed Description

After providing informed consent, individuals will undergo 6 weeks of chiropractic care. Throughout these 6 weeks there will be three assessments (Day 0, Week 2, and Week 6) that each include the following:

1. Seated resting recording

2. Auditory oddball task

3. Isometric hand grip

4. Postural challenge

5. Treadmill walking

6. Patient-reported outcome surveys

Each assessment will consist of the following recordings:

1. Electroencephalography \[EEG\]

2. Electrodermal activity \[EDA\]

3. Impedance cardiography \[ICG\]

4. Electrocardiogram \[ECG\]
