Evaluation and treatment for chronic pain are major contributors to rising healthcare costs; however, systematic, objective assessment of the functional impact of pain remains exceptionally challenging. Barron Associates has developed the KnowPain wearable instrument to objectively and quantitatively assesses the functional impact of chronic pain (FIP) using measures derived from motion and physiologic data via a specially designed, ergonomic wrist-worn biometric sensing instrument.
A feasibility study with chronic pain patients evaluated a prototype instrument with respect to standard pain assessment questionnaires. The study found a statistically significant relationship between the KnowPain and multiple common assessment scales. Additionally, the usability of the device was assessed, resulting in a normative score in the top 3% of existing commercial products.
