Effects of Short-Term Limitation of Movement of the First Metatarsophalangeal Joint on the Biomechanics of the Ipsilateral Hip, Knee, and Ankle Joints During Walking

Abstract

Background We analyzed the effect of limitation of movement of the first metatarsophalangeal joint (FMJ) on the biomechanics of the lower limbs during walking. Material/Methods Eight healthy college students completed walking under barefoot (BF) and FMJ constraint (FMJC) conditions. We synchronously collected kinematics and dynamics data, and calculated the torque, power, and work of hip, knee, and ankle joints. Results Compared with normal conditions, when the FMJ is restricted from walking, the maximum ankle dorsiflexion angle is significantly increased ( P <0.001), the maximum plantar flexion angle is significantly reduced ( P <0.001), the maximum plantar flexion torque ( P <0.001) and the maximum dorsiflexion torque ( P <0.05) increased significantly, the maximum power increased significantly ( P <0.001), the minimum power decreased significantly ( P <0.001), and the negative work increased significantly ( P <0.001). The torque of hip and knee joints increased significantly ( P <0.05). Conclusions After the movement of the FMJ is restricted, the human body mainly compensates and transfers compensation by increasing the angle of dorsiflexion, increasing work and the activity level of surrounding muscles through the ankle joint, thereby increasing the torque load of the knee and hip joints to maintain the dynamic balance of kinematics. FMJC condition increases the energy consumption of the human ankle, knee, and hip joints during walking. The load is compensated by the gradual attenuation of the ankle, knee, and hip. Long-term limitation may cause damage to the posterior calf muscles and increase the incidence of knee arthritis.

Biomechanics Analysis of the Lower Limbs in 20 Male Sprinters Using the International Society of Biomechanics Six-Degrees-of-Freedom Model and the Conventional Gait Model

“…Kinetic evaluation was performed in a gait laboratory, using a three-dimensional gait analysis system (including a 6-camera motion analysis system and a force plate), in a blinded manner by the same assessor [ 18 ]. A 10-meter-long runway served as the patient’s walking route.…”

Development of Physical Exercise Prescription Application for Reduction of Functional Movement Limitation in College Students

“…Due to the unhealthy lifestyles of college students such as indifference to health awareness, long desk time, insufficient physical exercise, insufficient sleep, and irregular work and rest, the physical condition of college students is not optimistic (Mao Zhenming et al, 2022). Xu, R et al (2021) found that after the joint function is limited, the body will compensatory increase the activity level of surrounding muscles to maintain dynamic balance during exercise. Although the physical fitness test of college students is held every year, the content of the test cannot reflect the problems related to the joint function of college students, and the students were not aware of their joint function problems.…”

The Influence of Short-term Restriction of Unilateral First Metatarsophalangeal Joint on the Contralateral Lower Limb Joints

“…We refer to our previous experimental methods [18], Recruit The equipment used in this experiment is mainly composed of the gait walking test bench (Figure 1A), the data acquisition system, and the FMJC device (Figure 1BC). The FMJC device used in the test consists of a low-temperature thermoplastic sheet provided by Convalesce ® , medical gauze and Velcro marking points.…”

“…[11,12]. The flexion and extension of the MJ will have an important The results of our previous research show that [18], the FMJ constraint (FMJC) condition will increase the energy consumption of the ipsilateral ankle, knee, and hip joints. When the FMJ is restricted, the body mainly performs load generation through the ipsilateral hip, knee, and ankle joints.…”
