Post-concussion Syndrome and Chiropractic

Summary

This proof-of-concept trial will explore the effects of manual chiropractic adjustments on nervous system function in individuals with post-concussion syndrome. This study will aim to recruit 10 individuals to receive 6 weeks of chiropractic care with 3 assessment periods. The participants will undergo a baseline assessment, mid-trial assessment, and post-trial assessment. The participants will wear an electroencephalography (EEG) cap for a neural assessment during an event related potential. They will wear electrical diodes to measure electrocardiography (ECG), impedance cardiography (ICG), and electrodermal activity (EDA) throughout the study and during an orthostatic challenge. Additional sensors will be placed on the participant to measure interlimb symmetry patterns during gait while walking on a treadmill.
