This article reports the development of an observational rating scale for the assessment of the quality of walking in adults with chronic pain called the Bath Assessment of Walking Inventory. A review of the literature on movement assessment, and a professional focus group, yielded 36 items capturing specific characteristics of walking that were organised into 11 domains. Investigation into the psychometric properties reduced the final measure to 23 items in 8 domains that demonstrated good internal consistency and adequate intra and inter-rater reliability. Validity was established in comparison with well-used measures of functioning. Further independent study is required to develop this instrument.
A robust measure of walking will enable accurate clinical assessment, and the investigation of psychosocial and biomechanical influences on walking quality, and of the communicative function of pain related movement.
