The pupil diameter, controlled by sympathetic and parasympathetic innervation, is a direct reflection of autonomic nervous system (ANS) activity. This study aims to investigate the clinical feasibility of using pupillary activity measured with a cost-effective eye tracker as a measure of ANS function in people under chiropractic care. Computerised pupillometry is a low cost, non-invasive objective measure that could potentially be a useful outcome measure for chiropractors in practice to assess nervous system function in their patients.
