Various clinical scales are available to investigate balance impairment, Mini-BESTest is one of them. Thus, this study aims to translate the Mini-BESTest into Urdu and investigate its psychometric properties in the Pakistani Parkinson's population with dynamic balance impairment.

The aim of study is to translate and culturally adapt Mini-BESTest into Urdu language and secondly to investigate the reliability and validity of Urdu Version of Mini-BEStest in Parkinson's Pakistani population. This study will be cross sectional survey study in which convenience sampling technique will be used.

The results of study will help to know the validity and reliability of Mini-BESTest in Urdu version with dynamic balance impairments in Parkinson's population. The reliability of the scale will be checked through internal consistency and test-retest methods. Internal consistency will be analyzed with Cronbach's alpha value. Test-retest reliability will be assessed using an intraclass correlation coefficient with 80 patients.

The incidence of Parkinson disease increases by age especially after the age of 60 As we know equilibrium and postural control are essential for everyday work so postural instability, freezing of gait, impaired anticipatory and reactive balance, impaired cognition ,reduced leg muscle strength, reduced proprioception, and frontal lobe impairment are major cause of balance impairment and falls in persons with Parkinson disease and falling puts persons with Parkinson disease at a higher risk of fractures, soft tissue injury, immobilization, depression, daily activity restriction, and mortality
