“…In addition, trunk ROM was signi cantly and negatively correlated with the sagittal ROM of the hip, knee, and ankle joints during the mid-swing to terminal swing phases. A previous study has shown that the range of ankle dorsi exion is negatively correlated with internal thigh rotation, trunk exion, and pelvic anteversion [29]. ROM of trunk rotation and lower limb joints in the sagittal plane has not been previously reported; thus, a comparison was not possible.…”

Background: The ability to walk is crucial for maintaining independence and a high quality of life among older adults. Although gait characteristics have been extensively studied in older adults, most studies have investigated muscle activity in the joints of the trunk or the lower limbs without assessing their coordinated interactions. Thus, the causes of altered trunk and lower limb coordination patterns and gait changes among older adults remain unknown. Therefore, this study compared the joint kinematic parameters of both the trunk and lower limbs of young versus older adults to identified key factors leading to changes in gait among older adults. Methods: In total, 64 older (32 males, aged 68.34 ± 7.38 years; 32 females, aged 67.16 ± 6.66 years) and 64 young (32 males, aged 19.44 ± 0.84 years; 32 females, aged 19.69 ± 0.86 years) healthy adults participated in this study. The range of motion (ROM) of the thorax, pelvis, and trunk in the horizontal plane and of the hip, knee, and ankle joints of the lower limbs in the sagittal plane were measured using a motion capture system with wearable sensors. Two-way analysis of variance assessed differences in ROM by age, sex, and basic gait parameters; Pearson correlation analysis assessed the coordinated patterns of the trunk and lower limbs, identifying key factors leading to gait changes in older adults. Results: Gait length, speed, and stride in young adults were greater (p < 0.001) than those in older adults, but older women displayed the fastest stride speed (p < 0.05). ROM values for the pelvis, thorax, trunk, knee joint, and ankle joint of young adults were greater (p < 0.05) than those in older adults. However, hip ROM in older adults was significantly greater than that in young adults (p < 0.05). Conclusion: With increasing age, ROM of the lower limbs, especially the ankle joint, decreased significantly, resulting in a significant decrease in gait speed. As ROM of the pelvis decreased, stride decreased significantly in older adults, who compensate through thoracic rotation. Thus, older adults should enhance muscle strength and increase ROM to improve gait patterns and quality of life.

“…There was also a significant difference between the vest and barbell on the ankle PFA. According to Guilherme et al [ 43 ], in their study, the dynamic ankle dorsiflexion range may be changed by neuromuscular strategies induced by factors outside of the passive ankle dorsiflexion range. For example, factors of hip and knee muscle weakness may be associated with an increased demand for plantar flexors.…”

Objective: The lunge squat is one of the exercises to strengthen the lower limbs, however, there is little evidence of the effects of different equipment. The purpose of this study was to investigate the biomechanical effects of different types of equipment and loads on the lunge squat’s effect on the lower limbs. Methods: Fourteen male fitness novices participated in the experiment. Kinematics and kinetics in the sagittal plane using dumbbells, barbells, and weighted vests were measured using OpenSim. Two-way repeated measures ANOVA and one-dimensional statistical parametric mapping were used in the statistical analysis (SPM1D). Results: Range of motion (ROM) change in the knee joint was more obvious when using a barbell, whereas ROM when using a dumbbell was minimal. Compared to other joints, the joint moment at the hip joint was the largest and changed more significantly with increasing weight-bearing intensity, and the change was more pronounced with the dumbbell. For the center of pressure (COP) overall displacement, the dumbbell produced a smaller range of displacement. Conclusions: Dumbbells are suggested for male beginners to improve stability, barbells for the more experienced, and a low-weighted vest may be more appropriate for those with knee pain.

“…Greater passive ankle dorsiflexion range seems to be associated with a better lower limb alignment during the single-leg squat [ 24 ], and paretic ankle dorsiflexion and knee extension torques were negatively correlated with the duration of self-sit to stand performance in stroke patients [ 25 ]. In addition, dorsiflexion ROM restrictions are associated with a greater risk of anterior cruciate ligament injury because in the squat posture the ground reaction force transmitted to the knee increases and the valgus displacement increases due to the decreased dorsiflexion angle [ 26 ].…”

Knee Muscles Strength Can be Improved by Using an Elastic Band as an Assistive Device for Knee-Ankle Complex

Background There are various tools and methods used for strength exercise. Elastic bands, one of the resistance exercise tools, have been used for various purposes, including muscle strengthening; however, there is very little evidence supporting their efficacy. The study was performed to investigate the effect of knee-ankle elastic bands on knee muscle strength-related parameters according to sex in healthy adults. Material/Methods This was a cross-sectional study. Twenty-one participants (11 female and 10 male) were studied using a cross-over design. Isokinetic concentric knee extension and flexion strength was measured at 60°/s and 180°/s with and without application of a therapeutic elastic band in the shape of an “8”, with knee flexion and ankle dorsiflexion. The variables related to muscle power automatically calculated in the protocol of the isokinetic system were compared according to sex and angular velocity. Results Peak moment (PM), PM/body weight, average power, total work, and the agonist/antagonist ratio, demonstrated significant improvement ( P <0.05) at both 60°/s and 180°/s “with” compared to “without” the elastic band according to sex. Conclusions The use of therapeutic elastic bands in the shape of a figure 8 with knee flexion and ankle dorsiflexion may be used as assistive devices for improving strength in muscles supporting the knee. Further high-quality studies are needed to assess the potential of elastic bands as assistive devices and not merely as exercise tools. Therapeutic elastic bands in the shape of an “8” with knee flexion and ankle dorsiflexion may be useful in sports activities.
