Physical performance tests have excellent reliability in frail and non-frail patients with prostate cancer

Abstract

Purpose

Our aim was to investigate the test-retest reliability of the 2-min walk test (2MWT), timed up and go test (TUG), and five times sit-to-stand test (FTSST) in prostate cancer (PC) patients.

Methods

This study was conducted with 73 patients who were classified into two groups as frail and non-frail determined by the Geriatric-8 questionnaire. Patients performed the 2MWT, TUG, and FTSST tests for two times. The test-retest reliability of the 2MWT, TUG, and FTSST was assessed by calculating the intraclass correlation coefficient (ICC). The standard error of measurement (SEM₉₅) and minimal detectable change (MDC₉₅) values were calculated.

Results

All tests showed excellent test-retest reliability for both groups (ICC_(2.1) > 0.90). The SEM₉₅ and MDC₉₅ values of 2MWT were 3.09, 8.57, and 3.15 m, 8.73 m for frail and non-frail groups. The SEM₉₅ and MDC₉₅ values of TUG for the frail group were 0.6 and 1.66 and 0.43 and 1.19 for the non-frail group, respectively. The SEM₉₅ and MDC₉₅ values of FTST for the frail group were 0.68 and 1.88 and for the non-frail group 0.86 and 2.38.

Conclusions

The 2MWT, TUG, and FTSST showed excellent reliability in frail and non-frail older adults with PC which can be used to assess physical performance.

IMPLICATIONS FOR REHABILITATION

• The 2-minute walk test (2MWT), Timed up and go test (TUG) and five times sit to stand tests (FTST) are excellent reliable tests for both frail and non-frail prostate cancer patients.

• The Minimal Detectable Change (MDC95) value of 2MWT, TUG, and FTST provides important information to clinicians about the clinical progression of oncological patients

• Clinicians can use one of this evidence-based outcome measures to check change of independent mobility performance with prostate cancer patients.
