Effectiveness of the video teach-back method in reducing kinesiophobia among patients following unilateral total hip arthroplasty: a quasi-experimental study

BACKGROUND: Kinesiophobia is a significant factor affecting the prognosis of patients with total hip arthroplasty (THA). At present, the primary intervention for kinesiophobia is a 1-way intervention process of healthcare professionals on patients. The video teach-back method uses bidirectional information feedback to ensure high-quality health education. However, little is known about the effect of the video teach-back method on kinesiophobia in patients after unilateral THA. PURPOSE: To explore the effect of the video teach-back method on the degree of kinesiophobia, hip function, the first ambulation time, hospitalization days, and hospitalization costs in patients after THA. METHODS: This quasi-experimental study was conducted in the Department of Joint Surgery of a grade III hospital in Changchun City, Jilin Province, targeting patients with kinesiophobia following unilateral THA. A nonconcurrent control design was employed, with participants divided into an intervention group (n = 46) and a control group (n = 45). The control group received conventional care, while the intervention group received video teach-back intervention in addition to traditional care. Within 24 hours post-surgery, patients with a kinesiophobia score of more than 37 completed a general information questionnaire. Primary outcomes, including kinesiophobia and hip function, were assessed on discharge day, 1 and 3 months after surgery, and counted on the day of discharge. Repeated-measures analysis of variance was used to analyze the differences in observation indexes at different time points. Secondary outcomes included the first postoperative ambulation time, hospitalization days, and hospitalization costs. RESULTS: In comparison between the intervention group and the control group, the kinesiophobia scores and hip function scores of the patients on the discharge date, the first and third months after surgery, had a time effect (P < .001), a group effect (P < .001). The intervention group's reduction in kinesiophobia had a significant effect size (Cohen's d = 0.82) and hip function improvement also demonstrated a significant effect size (Cohen's d = 0.77). The first postoperative ambulation time in the intervention group was significantly earlier than that in the control group (P < .05, Cohen's d = 0.55), with both hospitalization days and costs lower than in the control group; the differences were statistically significant (P < .05). CONCLUSION: The intervention group showed improvements in kinesiophobia, hip function, first postoperative ambulation time, hospitalization days, and hospitalization costs. These findings suggest that the video teach-back method, as an effective intervention, can be widely applied in clinical practice. TRIAL REGISTRATION NUMBER: The trial was registered with the Chinese Clinical Trial Registry (registration number: ChiCTR2400079966).
