Floor-to-Stand Performance Among People Following Stroke

Studies have examined floor-to-stand performance in varied adult populations both quantitatively and qualitatively. Despite an elevated risk of falls and inability to independently return to stand after a fall, few have examined the ability to stand from the floor in patients recovering from stroke. There were 2 objectives of the study: to identify the relationships between floor-to-stand performance using a timed supine-to-stand test (TSS) and physical performance measures of gait, balance, and balance confidence among persons in the subacute phase after stroke; and to analyze descriptive strategies used in the completion of the TSS.

A cross-sectional design was implemented. Fifty-eight adults (mean age = 59.2 [standard deviation (SD) = 13.9] years; 34 [58.6%] men) who were in the subacute phase after ischemic or hemorrhagic stroke and who could stand from the floor with no more than supervision completed the TSS and physical performance assessments.

The median time to complete the TSS in our sample was 13.0 (interquartile range = 15.5) seconds. TSS time was significantly correlated with physical performance tests, including the Timed "Up & Go" Test (ρ = 0.70), gait speed (ρ = -0.67), Dynamic Gait Index (ρ = -0.52), and Activities-Specific Balance Confidence Scale (ρ = -0.43). Thirty-two percent of the variance in TSS time was attributed to Timed "Up & Go" Test time and the use of the quadruped position to transition to standing. Participants who used a gait device were more likely to use a chair during rise to stand.

The TSS demonstrates concurrent validity with physical performance measures.

Findings serve to improve functional mobility examination after stroke and to formulate effective treatment interventions to improve floor-to-stand performance.
