However, responses in PwVH depended on the vestibular lesion side and functional compensation as assessed by the Functional Gait Assessment (FGA). PwVH had larger changes in stability when perturbations caused body movement toward the side of the lesion and more effective trunk responses when perturbations caused body movement away from the lesion. Additionally, PwVH who performed poorly on the FGA showed worse stability and overactive ankle and trunk responses following medial perturbations.ConclusionsThese findings demonstrate kinematic differences in balance recovery in PwVH and suggest that PwVH are more susceptible to instability when falling toward the lesion.</p>","PeriodicalId":49960,"journal":{"name":"Journal of Vestibular Research-Equilibrium & Orientation","volume":" ","pages":"9574271251358767"},"PeriodicalIF":2.9,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144638505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous studies have found kinesiophobia in patients with vestibular disorders. This research study aimed to develop and measure the psychometric properties of the Tampa Scale of Kinesiophobia (TSK-11), for use in persons with dizziness (TSKd).MethodsAn observational validation study of questionnaires was carried out including 211 participants with dizziness. After adapting the TSK-11 items to the symptoms of dizziness, the construct validity was evaluated with principal component analysis (PCA), internal consistency with the calculation of Cronbach's alpha, test-retest reliability with the intraclass correlation coefficient (ICC), concurrent validity with Spearman correlation and predictive validity with ROC curve analysis.ResultsThe PCA retained 10 items from the original scale with a three-factor structure that mediates fear (TSKd_f), negative thoughts (TSKd_n) and avoidance (TSKd_a). Cronbach's alpha was 0.810 for the 10-item TSKd. Reproducibility was moderate to substantial, with ICCs between 0.69 and 0.84. The TSK showed strong correlations with the DHI, while correlations with other dizziness measures were moderate. A TSKd score >25 and TSKd_f score >9 showed good predictive capacity, with an area under the curve (AUC) ROC of 0.85 and a sensitivity and specificity between 0.85 and 0.70.ConclusionsThe TSKd is a tool available for measuring kinesiophobia in persons with dizziness.
