Abstract:
Background: Stroke, the sudden death of some brain cells due to lack of oxygen when the blood flow to the brain is lost by blockage or rupture of an artery to the brain, is also a leading cause of dementia and depression. Objective: To translate, culturally adapt and estimate psychometric properties of the Urdu version of the simplified modified Rankin scale in stroke patients. Material and Methods: According to the predefined guidelines, translation and cultural adaptation were performed by recruiting 150 participants (48% men and 52% women) aged 40- 65 years diagnosed with sub-acute stroke. The sample size was calculated to be 150 by using Kline method. A purposive sampling technique was used for data collection and data were collected from the Department of Physical Therapy, University of Lahore Teaching Hospital. People who were neurologically unstable, unable to read Urdu, unwilling participants or people who are on respirators were excluded from the study. The final Urdu version of the simplified modified Rankin scale was tested for test-retest reliability, internal consistency, inter-item correlation, and construct validity. Results: The Urdu-SMRS demonstrated Excellent test-retest reliability (ICC= 0.973 (0.808-0.880.973 (0.963-0.981); CI=95 percent). Cronbach's alphawas 0.97, indicating that this scale has excellent internal consistency. The study found a strong correlation between the simplified modified Rankin scale Urdu version and the Barthel index, showing that this scale has strong convergent validity. Conclusion: The Urdu version of the simplified modified Rankin scale is a reliable and valid instrument to measure functional assessment after stroke in the Pakistani population with excellent psychometric properties.
