Effect of different degrees of weight-bearing jogging tests on lower limb dynamic parameters in elderly patients with knee osteoarthritis
Objective The effect of different degrees of weight-bearing on lower limb dynamic parameters was determined in elderly patients with knee osteoarthritis.Methods One hundred and eight patients with knee osteoarthritis who were admitted to the 363 our hospital from January 2020 to April 2023 were selected as the study subjects.The patients were randomly divided into 0％(n=36),5％(n=36),and 15％body weight(BW)groups(n=36),using a digital randomization method.The three-dimensional ground reaction force,frontal lower limb joint angle,sagittal lower limb joint angle,and knee joint dynamics parameters of the three groups of patients were determined during weight-bearing jogging.Results As the weight increased,the ground reaction forces in the three-dimensional direction gradually increased.The ground reaction forces in the 5％and 15％BW groups were both greater than the 0％BW group(P＜0.05).The differences between the 0％,5％,and 15％BW groups with respect to the knee joint adduction,ankle joint inversion,and ankle joint eversion angle peaks were statistically different(P＜0.05).The knee joint adduction angle peak value was significantly decreased in the 5％and 15％BW groups compared to the 0％BW group while the ankle joint inversion and eversion angle peak values were significantly increased.There was no statistically significant difference in the lower limb joint peak values on coronal plane images among the three groups(P＞0.05).The differences in peak ankle dorsiflexion and ankle plantar flexion angles among the 0％,5％,and 15％BW groups were significantly different(P＜0.05).The peak ankle dorsiflexion angle was significantly increased in the 15％BW group,while the peak ankle plantar flexion angle was significantly decreased.There was no statistically significant difference in the lower limb joint peak angle in the sagittal plane among the three groups(P＞0.05).The difference in EKAM and EKFM peak values among the three groups was statistically significant(P＜0.05).The EKAM and EKFM peak values were significantly increased in the 15％BW group.Conclusions Different degrees of weight-bearing impact the changes in lower limb dynamic parameters in elderly patients with knee osteoarthritis.
