PURPOSE: To assess relative reliability and measurement error of the Graded
Cycling Test (GCT) with the Talk Test (TT) for patients with cardiac disease.
METHODS: Patients (N = 64; women, n = 30) with ischemic heart disease performed
the GCT with the TT twice in 1 day. Every minute the patient recited a text
passage of 30 words. The question "Are you still able to speak comfortably?" was
then answered: "Yes" (TT+), "Not sure" (TT+/-), or "No" (TT-). Two
physiotherapists (PTs) rated when the speaking ability was affected by
ventilation. Relative reliability: intraclass correlation coefficient (ICC)2.1
and absolute reliability: standard error of measurement with 95% CI (SEM95) and
smallest real difference (SRD) were calculated. RESULTS: Intraclass correlation
coefficient values of 0.90, 0.91, and 0.90 were observed for TT+, TT+/-, and TT-,
respectively. Physiotherapist ICCs ranged between 0.81 and 0.88. SEM95 ranged
between 17.2 and 18.3 watts (W), with corresponding SRD values between 24.4 and
25.9 W for the patient ratings. The PT ratings ranged between 15.8 and 21.4 W
(SEM95) and between 22.3 and 30.3 W (SRD). CONCLUSIONS: The TT, combined with the
GCT, was well tolerated by patients with cardiac disease in clinical settings
with small measurement error and an excellent relative reliability. These results
apply to both patient-rated and PT-rated TT.
