ABSTRACT

Objective:

To observe the impacts of muscle visual feedback intervention combined with continuous nursing on exercise ability of patients with knee osteoarthritis (KOA), so as to provide a reference for improving the rehabilitation quality of KOA patients.

Methods:

Using a randomized controlled trial method. The 104 KOA patients admitted to the Department of Arthrology and Sports medicine of the Affiliated Hospital of Jining Medical University from December 2020 to December 2021 were selected as the research objects by convenient sampling method. They were divided into the control group and the research group according to the random number table method, with 52 cases in each group. The control group was given routine care, and the research group was given muscle visual feedback intervention combined with continuous care on the basis of the control group. Before and after the intervention, the knee joint function, range of motion of the affected knee joint and exercise ability of the two groups were compared.

Results:

After the intervention, the Hospital for Special Surgery (HSS) Knee scores of pain, function, range of motion, muscle strength, flexion deformity and stability in the study group were 21.39 ± 4.21, 17.08 ± 2.43, 13.92 ± 2.02, 8.52 ± 0.54, 8.12 ± 0.74 and 8.04 ± 0.89, which were higher than those of the control group 19.68 ± 4.14, 16.12 ± 2.08, 13.11 ± 1.89, 7.76 ± 0.62, 6.85 ± 0.68, 7.11 ± 0.94, and the differences were all statistically significant ( t values were 2.09-9.11, all P<0.05). After the intervention, the flexion-extension, internal rotation and external rotation of the affected knee in the study group were (90.83 ± 14.26)°, (20.89 ± 3.72)° and (30.72 ± 3.86) °, respectively, and those in the control group were (76.78 ± 24.74)°, (16.81 ± 4.63)° and (24.62 ± 5.07) °, respectively, and the differences were statistically significant ( t=3.55, 4.95, 6.90, all P<0.05). After the intervention, the Fugl-Meyer assessment scale score of the study group was 24.72 ± 4.38, which was higher than 21.15 ± 4.64 of the control group, and the difference was statistically significant ( t=4.04, P<0.05).

Conclusions:

Muscle visual feedback intervention combined with continuous nursing can improve the knee joint function, range of motion of the affected knee joint and exercise ability of KOA patients.
