Relationship between kinesiophobia and performance in a functional capacity evaluation.

Fear of movement and (re)injury (kinesiophobia) has been postulated to play an important role in the performance in a Functional Capacity Evaluation (FCE). This study was performed to analyze the relationship between kinesiophobia and performance in an FCE. Kinesiophobia and FCE performance of 54 male and 10 female patients (mean age 38.0) suffering chronic low back pain (mean length of episode 9.9 months, 93% off work) were assessed. Kinesiophobia was assessed using the Dutch Version of the Tampa Scale for Kinesiophobia (scale 17-68). A lifting task and an FCE were operationalizations of avoidance. FCE results were transformed into a single measure using the classification of the Dictionary of Occupational Titles (FCE-DOT, scale 1-5). Correlations between the variables were calculated. The results are: kinesiophobia mean 41.6 (SD 7.3), lifting mean 29.5 kg (SD 11.6), FCE-DOT mean 3.6 (SD 0.6). Correlations between kinesiophobia and lifting was r = 0.01 (p = 0.93) and between kinesiophobia and FCE-DOT was rho = -0.04 (p = 0.75). The results indicate that the patients were substantially kinesiophobic, yet they were able to lift a mean of 29.5 kg and were physically able to perform moderate to heavy work. The strength of the correlations was very low. The relationship between kinesiophobia and avoidance, operationalized as lifting and an FCE, could not be confirmed in this study.

Concurrent validity of questionnaire and performance-based disability measurements in patients with chronic nonspecific low back pain.

This study aimed to investigate the concurrent validity of two approaches to disability measurement in patients with chronic nonspecific low back pain (CLBP). It was hypothesized that if both are measuring the same construct, the instruments would lead to similar disability results and would correlate strongly (r > 0.75). The study compared the results of self-reported and performance-based measures of disability in 64 consecutive patients with CLBP. Participants mean age was 38.0 years, the mean duration of the current episode of back pain 9.9 months, and 90% were off work due to CLBP. The self-report measures used were: the Roland Disability Questionnaire (Roland); the Oswestry Disability Questionnaire (Oswestry); and the Quebec Back Pain Disability Questionnaire (Quebec). Performance was measured using the Isernhagen Work Systems Functional Capacity Evaluation (FCE). The mean scores from the self-report measure are as follows: Roland 13.5 (scale 0-24), Oswestry 28.2 (scale 0-100), Quebec 37.8 (scale 0-100) consistent with moderate to severe disability. In contrast the results from the performance-based measures suggested that the subjects should be able to work at a physical intensity level of moderate to heavy. Little to moderate correlation was observed between the self-report and performance-based measures (Spearman rank correlations: Roland-FCE (-0.20), p > 0.05; Oswestry-FCE (-0.52), p < 0.01; Quebec-FCE (-0.50), p < 0.01). Results are interpreted to suggest that both performance-based and self-report measures of disability should be used in order to obtain a comprehensive picture of the disability in patients with CLBP.
