“…Only a little amount of study has been done to determine the relationship between muscle activation patterns, especially the moment of the vastus lateralis, medial gastrocnemius, and rectus femoris in connection to the knee OA development. Patient with knee osteoarthritis was reported has a slow walking speed compared to normal individual (Akimoto et al, 2022). Walking speed also has become one of the important predictors of outcome for knee OA intervention (Harkey, et al, 2021).…”

Computational modelling is a tool that provide accurate readings and simulation by using a combination of trusted and tested mathematical models of materials and system dynamics. Existing study in gait analysis mostly focus on extrinsic parameter such as kinetics and kinematics measures. The analysis of gait especially for disease such as knee osteoarthritis (OA) can provides insight into muscle properties, activation pattern and potential impact on the knee stability and function. This study aims to simulate and compare muscle activation properties in normal individual and individuals with knee osteoarthritis (OA) during gait phases. This study used musculoskeletal modeling software, OpenSim, to analyze the total fiber force and moment of several key muscles (such as medial gastrocnemius, vastus lateralis, and rectus femoris) relative to knee flexion moments. The motion analysis data of three subjects (one normal subject and two knee OA patients) were used in this study. The results shows that total muscle fiber force and muscle moment for medial gastrocnemius and vastus lateralis muscle were higher among individual with knee osteoarthritis. Meanwhile, rectus femoris muscle behaved differently where both parameters were smaller among knee OA patient. These simulated findings suggest that muscle mechanism changed due to knee osteoarthritis disease. The muscles force and moment were observed in this study gave some insight on the devastating effect of the disease on the lower limb joint muscle. Thus, further study is still warranted to investigate the risk of muscle injury and alteration of gait on individual with knee osteoarthritis. It is highly recommended to repeat this study with larger number of subjects for a better data interpretation.

“…Static plantar pressure analysis is widely used in the study of patients' balance function [10]. Previous studies have reported abnormal balance function in patients with KOA, which is characterized as a great amount of swing on the center of gravity in the left and right directions during one-leg stance and impaired postural control [8,9,11]. In the present study, the static plantar pressure of unilateral KOA patients tended to be distributed on the unaffected side, which is caused by a compensatory behavior of trunk lateral flexion to alleviate pain on the knee [5,12], manifested as pelvic rotation and reduction of weight bearing on the affected side.…”

Background:Plantar pressure analysis is widely used in the study of knee osteoarthritis (KOA). The present study aimed to investigate the static and dynamic plantar pressure distribution in patients with different stages of unilateral KOA using the Footscan® platform system. Material/Methods:We recruited 94 patients aged 61.75±7.23 years old with different stages of unilateral KOA for static and dynamic analysis using the Footscan ® platform system. The static pressure (%) of the left, right, anterior, posterior, and the pelvic rotation (°) was assessed. The peak pressure (PP, kPa) was investigated in 10 areas of the foot: medial heel (MH), lateral heel (LH), midfoot (MF), first to fifth metatarsals (M1-M5), hallux (T1), and toes 2-5 (T2-5). The correlation between KOA stages and plantar pressure distributions was investigated. Results:The results revealed that static pressure on the unaffected side and pelvic rotation were positively correlated with KOA stages. In addition, there was a positive correlation between KOA stages and PP of M5, MF, and LH zones on the affected side and PP of M2, M3, and M4 zones on the unaffected side, and a negative correlation between KOA stages and PP of T1 and T2-5 zones on the affected side. Conclusions:With the progression of KOA, static plantar pressure tends to distributed on the unaffected side, and the dynamic plantar pressure tends to be distributed laterally on both feet. The plantar pressure distributions in unilateral KOA patients are abnormal and are closely related to the severity of KOA.

“…Gait variability is an indicator that can quantify to postural stability and showed to be predict to faller based on lack of balance ability when compared with gait speed and functional status by a previous study [ 12 ]. Moreover, the high gait variability was reported in patients with knee OA with an impaired functional ability [ 13 ] and was correlated with a poor clinical score [ 14 ] and fear of falling [ 15 ]. Then, the gait variability may serve as a potential indicator to assess ambulatory function in knee OA.…”

Background. Lateral thrust seen in people with medial compartment knee osteoarthritis can cause dynamic knee instability and poor postural control during gait cycles. A lateral wedge insole can reduce the lateral thrust and may have a favorable effect on gait variability, which in turn may indicate gait instability improves. The aim of this study was to investigate the effect of lateral wedge insole on gait variability in knee osteoarthritis patients. Method. We involved 15 symptomatic knee osteoarthritis patients who were provided with lateral wedge insole and 13 healthy asymptomatic volunteers as the control group. The gait variability was evaluated as the coefficient of variation of stride, stance, and swing duration based on acceleration monitoring using a wearable sensor. The lateral thrust was estimated as the lateral acceleration peak on the shank sensor. These measurements were performed without lateral wedge insole (baseline), immediately with lateral wedge insole (T0) at the initial office visit and one month after intervention (T1). Result. Our data showed that the stance duration coefficient of variation and lateral thrust at T1 in the knee osteoarthritis group, were significantly decreased compared to the baseline values and these values were identical to those in the control group. Conclusion. The lateral wedge insole reduces dynamic knee instability and could improve gait variability in medial compartment knee osteoarthritis.
