Community Balance and Mobility Scale

The Community Balance and Mobility Scale (CBMS) is a performance-based measure intended to evaluate balance and mobility skills in individuals who have experienced mild to moderate TBI (Inness et al. 1999). The scale is comprised of 13 items, each of which are rated on a 6-point scale from 0 to 5, where 5 represents the most successful completion of the scale item (Butcher et al. 2004; Inness et al. 1999).

Advantages. The CBMS is a measure developed specifically for use in assessment of individuals who have sustained mild to moderate TBI. It may have increased sensitivity to change when used within this population when compared to more established measures such as the Berg Balance Scale (Inness et al. 2011). 

Limitations. The scale may be assessing a construct more similar to “dynamic mobility” rather than balance per se (Inness et al. 2011). The information available in the literature with regard to the reliability, validity or practical application of this scale is extremely limited and arises from the original authors only. Additional evaluation of the CBMS’ psychometric properties is required. The CBMS is not appropriate for use on individuals with severe ABIs in which ambulation is affected because the CBMS was developed for people who are ambulatory (Inness et al. 1999).
