Summary
Timed Up and Go (TUG) performance in stroke patients is primarily linked to the paretic lower limb
Area of Science:
- Rehabilitation Medicine
- Biomechanics
- Neurology
Background:
- The Timed Up and Go (TUG) test assesses functional mobility in hemiparetic patients.
- It involves common daily motor tasks like standing, walking, and sitting.
- Previous studies have not explored TUG correlations with kinematic and kinetic gait parameters.
Purpose of the Study:
- To investigate if kinematic and kinetic gait parameters are more associated with TUG performance than spatio-temporal parameters in stroke patients.
- To identify gait variables that best explain TUG performance variability.
Main Methods:
- Sixty hemiparetic patients capable of independent walking participated.
- Participants underwent the TUG test, 3D gait analysis, and clinical evaluation.
- Stepwise regression analysis identified key gait variables predicting TUG performance.
Main Results:
- The single support phase on the paretic limb was the most predictive factor, explaining 67% of TUG performance variance.
- No kinematic or kinetic gait parameters significantly predicted TUG performance.
- TUG performance appears predominantly related to paretic lower limb motor function.
Conclusions:
- Timed Up and Go (TUG) test outcomes in hemiparetic individuals are mainly determined by paretic lower limb motor function, specifically the single support phase.
- Kinematic and kinetic gait parameters do not reliably predict TUG performance in stroke patients.
