Objective:
To characterise longitudinal trajectories of adherence to postoperative rehabilitation training and identify their predictors among patients with traumatic fractures.
Design:
This study adopted a longitudinal design.
Setting:
A tertiary hospital in Tianjin, China.
Participants:
A total of 317 patients with traumatic fractures who underwent postoperative rehabilitation training in the Department of Trauma Orthopedics between April 2024 and January 2025 were recruited.
Main Outcome Measures:
Patients were assessed using the General Information Questionnaire, Functional Exercise Compliance Scale for Orthopedic Patients, Modified Barthel Index, 13-item Sense of Coherence (SOC) Scale and Social Support Rating Scale at baseline and 4, 12 and 24 weeks after hospital discharge. Latent growth mixture modelling was used to identify longitudinal trajectories, and regression analysis was performed to determine predictors of trajectory-group membership.
Results:
The mean rehabilitation training adherence scores at baseline and 4, 12 and 24 weeks after hospital discharge were 52.97±5.94, 53.07±1.57, 54.46±1.68 and 55.05±5.24, respectively. Three distinct adherence trajectories were identified: a low-adherence increasing group (n=79, 24.9%), a moderate-adherence stable group (n=85, 26.8%) and a high-adherence declining group (n=153, 48.3%). Occupation, monthly income, place of residence, rehabilitation location, SOC and social support were significantly associated with trajectory-group membership.
Conclusions:
Three distinct trajectories of adherence to postoperative rehabilitation training were identified among adults with traumatic fractures, with the high-adherence declining group comprising the largest proportion. This group warrants particular attention and continued monitoring.
