Limiting factors of knee flexion angle and inferior patellar mobility in patients with knee osteoarthritis

Abstract

2) completed the exercise program and the gait evaluation. The average KAM and KFM was 0.49 Nm/kg and 0.47 Nm/kg at baseline. There was significant correlation between KAM and KFM (rho ¼-0.37, p ¼ 0.02). After the 6-week program, KAM decreased by 7.55 % to 0.45 Nm/kg (p ¼ 0.12), while KFM was significantly increased by 30.18 % to 0.62 Nm/kg (p<0.01). Though direct correlation between KAM and KFM was not significant (rho ¼-0.23, p ¼ 0.15), there existed significant correlation between decrease in KAM and increase in KFM (rho ¼-0.44, p ¼ 0.01). Conclusions: In patients with KOA, external joint loading along the sagittal and frontal plane was related. A higher peak knee adduction moment was associated with a lower knee flexion moment. More importantly, a greater reduction of knee adduction moment was associated with a greater increase in the knee flexion moment after a 6week exercise program. Such information might suggest exerciseinduced transforming of joint loading along the sagittal and frontal plane. Also, the efficacy of exercise program might associate with its direct effects on increasing the knee flexion moments than reducing the knee adduction moments in patients with KOA.

Effect of Core Balance Training on Muscle Tone and Balance Ability in Adult Men and Women

“…Factors that can be checked using the equipment currently used in rehabilitation medicine include muscle tone, stiffness, elasticity, recovery, and elongation [10][11][12][13]. However, research on muscle elasticity properties conducted to date has only targeted patients with muscle disease or the elderly [14][15][16][17]; it is necessary to expand the scope of studies to various individuals, including adults. In addition, a study on the lower extremities along with large muscles, such as the quadriceps, is required for the overall and balanced development of the lower body.…”
