Kinesiophobia and its association with functional outcome and quality of life 6-8 years after total hip arthroplasty
Bibliographic record
Abstract
OBJECTIVE: The aim of this study was to assess the incidence and severity of kinesiophobia, and to determine the relationship between Tampa Scale of Kinesiophobia (TSK) scores, functional outcome and quality of life (QoL) 6-8 years after Total Hip Arthroplasty (THA). METHODS: 161 patients (78 male and 83 female) with unilateral primary osteoarthritis (OA) treated with THA between September 2010 and December 2013 were included in this study. Western Ontario and McMaster Universities Osteoarthritis (WOMAC) and EQ-5D scores were measured preoperatively. At 6-8 years follow-up, these scores were repeated and TSK scores were also measured. According to the TSK, patients were divided into two groups for further comparisons and analysis: without kinesiophobia (TSK-score ≤ 36) and with kinesiophobia (TSK-score >36). RESULTS: There were 99 patients (61.5%) with no kinesiophobia (TSK score ≤ 36, TSK mean 28.4, SD 4.7) and 62 patients (38.5%) with kinesiophobia (TSK score > 36, TSK mean 42.8, SD 5.3). Patients with and without kinesiophobia were not statistically different regarding age, sex or body mass index. (P = 0.20, P = 0.99, P = 0.22, respectively). In the group with no kinesiophobia, the mean 6-8 years WOMAC was 12.4 (SD 15.6), while the absolute delta (Δ) value between preoperative and 6-8 years WOMAC was 46.2 (SD 20.4), compared to the group with kinesiophobia where the mean 6-8 years WOMAC was 32.2 (SD 23.4), while the absolute delta (Δ) value between preoperative and 6-8 years WOMAC was 32.3 (SD 25.5): both P < 0.001. The group with no kinesiophobia had a mean 6-8 years EQ-5D of 0.81 (SD 0.22), while the absolute delta (Δ) value between preoperative and 6-8 years EQ-5D was 0.44 (SD 0.26), compared to the group with kinesiophobia where the mean 6-8 years EQ-5D was 0.57 (SD 0.23), while the absolute delta (Δ) value between preoperative and 6-8 years EQ-5D was 0.33 (SD 0.26): P < 0.001 and P = 0.03, respectively. TSK scores were associated with worse WOMAC and EQ-5D scores, higher proportion of dependence on walking aids and increased THArelated adverse events (all P < 0.05). CONCLUSION: This study has shown us that there is a high incidence of kinesiophobia 6-8 years after surgery and treating kinesiophobia early after THA might improve the outcome. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
