Effects of trunk control, upper and lower extremity functions on functional activity, activities of daily living and quality of life in Parkinson's Disease

Purpose: To investigate the relationship between trunk control, upper and lower extremity function with functional activity, activities of daily living and quality of life in patients with Parkinson’s Disease (PwPD). Materials and Methods: The study was completed with 52 PwPD. Trunk control was evaluated with the Trunk Impairment Scale (TIS); upper extremity function with 9-Hole Peg Test (9-HPT) bilaterally; lower extremity function with 30-Second Sit-To-Stand Test (30STS); functional activity level with The Parkinson Activity Scale (PAS); activities of daily living with Barthel Index (BI); quality of life with The Parkinson's Disease Quality of Life Questionnaire (PDQ-39) Results: 30STS and right-left 9-HPT results was correlated with PAS and PDQ-39, but not with BI in PwPD. All TIS scores except the coordination sub-parameter were found to be associated with PAS, all TIS scores except the static sitting balance sub-parameter were found to be associated with BI, and all TIS scores were found to be associated with PDQ-39 in PwPD (ρ between 0.293 and 0.689; p
