Abstract:

Objective: The study investigates whether rehabilitation treatment for knee osteoarthritis under the rehabilitation treatment system based on ICF-OA core classification combination demonstrates superiority. Method: This study selected participants who visited Peking University Third Hospital between February and December 2022 and met the diagnostic criteria for knee osteoarthritis. Participants were randomly divided into three groups: Experiment Group 1 (rehabilitation treatment based on ICF concise core elements), Experiment Group 2 (rehabilitation treatment based on ICF comprehensive core elements), and Control Group (current conventional rehabilitation treatment plan for knee osteoarthritis). Each group consisted of 30 participants, with an intervention period of 3 months. Researchers used the ICF-OA core classification combination to evaluate patients before the intervention and followed up with them after 3 months of treatment, using the same three indicators for assessment during follow-up. Statistical methods were as follows: For patients' baseline data information, continuous data conforming to normal distribution were represented by mean and standard deviation, and group comparisons were conducted using analysis of variance. Data not conforming to normal distribution were represented by median and quartiles, and group comparisons were conducted using non-parametric Kruskal-Wallis rank-sum test. The differences within groups in ICF-OA were compared using median and quartiles, and the between-group differences in ICF-OA were compared using non-parametric Kruskal-Wallis rank-sum test. Results: In terms of physical function: After 3 months of treatment, all three groups showed improvements in the six aspects of b280 pain sensation, b715 joint stability, b720 skeletal movement function, b730 muscle strength function, b770 gait, and b780 sensation related to muscle and movement function, with statistically significant differences within the group (p<0.05). In terms of activity and participation: After 3 months of treatment, all three groups showed improvements in the six aspects of d410 changing basic body position, d415 maintaining a body position, d450 walking, d455 moving around, d640 doing housework, and d920 leisure and recreation, with statistically significant differences within the group (p<0.05). In terms of environmental factors: After 3 months of treatment, all three groups showed improvements in the six aspects of e110 personal consumer products or substances, e135 employment supplies and technology, e150 design of public buildings, e155 design of private buildings, e225 climate, and e540 transportation services, with statistically significant differences within the group (p<0.05). The comprehensive core plan group showed greater improvements in the aforementioned categories compared to the concise core plan group, with statistically significant between-group differences (p<0.05), while the concise core plan group showed greater improvements in the aforementioned categories compared to the traditional treatment group, with statistically significant between-group differences (p<0.05). Conclusions: This study provides a preliminary exploration of the superiority of rehabilitation treatment for knee osteoarthritis based on the ICF-OA core classification combination. The results showed that the comprehensive core plan group based on ICF-OA demonstrated better improvements in physical function, activity and participation, and environmental factors compared to both the conventional rehabilitation treatment group and the concise core plan group. Furthermore, the concise core plan group outperformed the conventional treatment group. This suggests that rehabilitation treatment for knee osteoarthritis (KOA) based on the ICF concept has superiority and good clinical practicability. It provides a valuable reference for therapists when choosing treatment plans and is beneficial for flexibly adjusting plans during the treatment process.
