BACKGROUND: The Tampa Scale of Kinesiophobia (TSK) is a commonly-used measure for the assessment of fear of movement beliefs in chronic complaints, but its responsiveness in subjects after lumbar fusion has been never reported.
AIM: Evaluating the responsiveness and minimal important changes (MICs) for the TSK and its subscales after lumbar fusion.
DESIGN: Population-based cohort study.
SETTING: Secondary care rehabilitation hospital.
POPULATION: In-patients undergoing rehabilitation after lumbar fusion.
METHODS: At the beginning and end of a four-week motor and cognitive-behavioural rehabilitation program, 180 patients completed the TSK. After the intervention, the global perceived effect (GPE) was analysed to produce a dichotomous outcome (improved vs. stable). Responsiveness for the TSK and its subscales were calculated by distribution [effect size (ES); standardised response mean (SRM)] and anchor-based methods (Receiver Operating Characteristics (ROC) curves; correlations between change scores of the TSK and its subscales and GPE). ROC curves were also used to compute MIC values.
RESULTS: The ES ranged from 1.63 to 1.77 and the SRM from 1.25 to 1.39 for TSK and its subscales. The ROC analyses revealed a value of Area Under the Curve [95% Confidence Interval (CI)] of 0.999 [0.978; 1.000], 0.998 [0.975; 1.000], 0.990 [0.962; 0.999] for the TSK, Harm and Activity Avoidance subscales, respectively. MIC values [95% CI] greater than 6 [>5; >6], 4 [>3; >5], and 2 [>2; >2] were achieved for the TSK, Harm and Activity Avoidance subscales, respectively. Correlations between change scores of the TSK and its subscales and GPE were high (0.786-0.830).
CONCLUSIONS: The TSK and its subscales were sensitive in detecting clinical changes in subjects undergoing rehabilitation after lumbar fusion.
