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.

Plain language summary

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