Relationship of Supine-to-stand Time and Bed Rise Quality with Trunk Control and Balance Among Post-stroke Survivors: A Cross-sectional Study.

Background: Stroke survivors typically exhibit sensory and motor deficits, variations in tone and postural dysfunction, which hamper important functional abilities like rising from bed. Research highlights the importance of postural control and balance with such transitions. However, limited research explores the relationship between rise from bed time and quality with trunk control and balance among stroke patients.

Purpose: The aim of this study was to find the correlation of supine-to-stand transition time and quality of bed rise with trunk control and balance among post-stroke patients.

Methods: Fifty-two post-stroke survivors who were able to rise from supine-to-standing independently participated in this cross-sectional study. Supine-to-stand time was recorded using a stopwatch, bed rise quality was assessed using Bed Rise Difficulty Scale (BRDS), trunk control using Trunk Impairment Scale (TIS) and balance using Berg Balance Scale (BBS). The strength of correlation was calculated using Karl Pearson's correlation coefficient.

Results: Among left hemiparetic participants, a moderate negative correlation was observed between supine-to-stand time and balance. Supine-to-stand time towards the paretic side moderately correlated with trunk control (r = -0.433, p = .013). Bed rise quality and balance showed a moderate negative correlation, irrespective of the side of rising. While rising towards the non-paretic side, the bed rise quality revealed a strong negative correlation with trunk control (r = -0.611, p < .001). For right hemiparetic participants, supine-to-stand time towards the paretic side strongly correlated with balance (r = -0.651, p = .002). Bed rise quality towards the non-paretic side showed a strong correlation with balance (r = -0.653, p = .002).

Conclusion: Post-stroke survivors who took a prolonged time to transition from supine-to-stand and demonstrated poor bed rise quality exhibited reduced trunk control and balance.
