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 \[ECG\]
Interventions
Participants will receive 6 weeks of chiropractic care. The frequency of care will be determined by the field clinician. Participants will have their spine assessed for the presence of vertebral subluxations per their clinician's normal and customary procedures. The adjustment technique(s) utilized by the field clinician will be at their discretion.
