What it measures:

Various functional abilities related to sitting balance, such as "sitting unsupported with eyes closed," "turning to look behind over left and right shoulders when sitting," and "picking up objects from the floor while sitting unsupported on foam." 11 items; 4-point Likert scale (0=worse performance, 4=best performance) (Medley & Thompson, 2011)

Target Population:

Frail older people

SBS is relatively new; future studies using a larger sample size are needed.

SBS may be comparable to TIS for measuring sitting balance in older adults who are nonambulatory or have limited mobility.

This test was identified by APTA's Section on Geriatrics and Home Health Section for use in functional limitation reporting.
