Characterization and Validation of the Short Physical Performance Battery in Individuals Diagnosed With Parkinson's Disease

Condition(s) studied

Study summary

Parkinson's disease (PD) is a progressive neurodegenerative disorder associated with motor and non-motor impairments that affect physical function, mobility, balance, and quality of life. Although Galicia is one of the Spanish regions with a high prevalence of PD, comprehensive information regarding the functional characteristics of this population remains limited.

This observational cross-sectional study aims to characterize the sociodemographic, clinical, cognitive, behavioral, and functional profile of individuals with Parkinson's disease in Galicia and to evaluate the validity and reliability of the Short Physical Performance Battery (SPPB) in this population. The findings will provide updated information on the functional status of people with PD in Galicia and support the use of the SPPB as a practical tool for the assessment of physical performance in clinical and research settings.

Eligibility

Primary outcome measure(s)

• Test-Retest Reliability of the SPPB — Baseline and 1 week
  Reliability of the SPPB assessed through repeated administration after a minimum interval of one week using the Intraclass Correlation Coefficient (ICC).
• Short Physical Performance Battery (SPPB) Total Score — Baseline
  Evaluation of lower-extremity physical performance through balance, gait speed, and chair-rise tasks. Total score ranges from 0 to 12, with higher scores indicating better physical performance.
• Internal Consistency of the SPPB — Baseline
  Internal consistency of the three SPPB components assessed using Cronbach's alpha coefficient.
• Convergent Construct Validity of the SPPB — Baseline
  Correlation of SPPB scores with established functional assessment measures (TUG, BBS, and MDS-UPDRS Part III).
