Abstract

This two-group repeated-measures quasi-experimental study aimed to examine and compare patient-reported and clinical outcomes among older adults with mild and moderate knee osteoarthritis. Assessments were conducted before the intervention and at 8 and 12 weeks after participation in the Modified Multifactorial Intervention Program (mMUFIP). A total of 83 participants were recruited. This included 38 with mild and 45 with moderate knee osteoarthritis. Both groups received the mMUFIP, which consisted of health education, weight management, exercise training, and home visits. Research instruments included the Six-item Cognitive Impairment Test (6CIT), Functional Reach Test (FRT), demographic questionnaire, clinical outcome assessment form, and the Arthritis Impact Measurement Scales 2–Short Form (AIMS2-SF). Data were analyzed using descriptive statistics, chi-square test, independent t-test, and Repeated Measures ANOVA. Statistical significance was set at p < .05.

The results revealed that participants in both groups had a mean age of 69.33 years (SD = 5.55). There were no significant differences in baseline characteristics (p > .05). After receiving the mMUFIP, psychosocial well-being improved in both groups. In the mild knee osteoarthritis group, scores decreased from 3.80 ± 1.44 to 0.86 ± 0.99. In the moderate group, scores decreased from 5.69 ± 1.82 to 1.72 ± 1.90. Significant between-group differences, time effects, and Group × Time interaction effects were observed (p < .05). Disease severity scores also decreased: from 13.71 ± 1.80 to 12.39 ± 2.38 in the mild group, and from 19.51 ± 1.93 to 14.27 ± 3.47 in the moderate group. Again, significant between-group differences, time effects, and Group × Time interaction effects were seen (p < .05). Pain scores dropped from 5.00 ± 2.21 to 1.84 ± 1.98 in the mild group, and from 7.20 ± 2.16 to 2.64 ± 2.68 in the moderate group. There were significant between-group differences and time effects (p < .05). In addition, body weight decreased and quadriceps muscle strength increased significantly over time in both groups (p < .05). No significant between-group differences or Group × Time interaction effects were found for these measures (p > .05).

These findings suggest that the mMUFIP is an effective intervention for improving psychosocial well-being, reducing disease severity, pain, and body weight, and enhancing quadriceps muscle strength among older adults with knee osteoarthritis. The program may be incorporated into community-based care to improve health outcomes in this population.
