In this paper, we propose a control strategy allowing us to perform the dynamic walking gait of a virtual under-actuated robot even subjected to destabilizing external disturbances. This control strategy is based on two stages. The first one consists in using a set of pragmatic rules in order to generate a succession of passive and active phases allowing us to perform the dynamic walking of the...

One of the factors that influence the outcome after rupture of the tendo Achillis is abnormality of gait. We prospectively assessed 14 patients and 15 normal control subjects using an in-shoe plantar pressure measurement system. There was a significant reduction in peak mean forefoot pressure in the early period of rehabilitation (p < 0.001). There was a concomitant rise in heel pressure on the...

There are assumptions that leg length discrepancy (LLD) may cause low back pain (LBP) by creating pelvic obliquity and lumbar scoliosis, although the exact means by which LLD causes or augments LBP is not clear. While it is evident individuals with LLD display compensatory movements in the lower limbs and pelvis, there is a scarce research regarding the effects of LLD on spinal motion. In this ...

Measuring biomechanical work performed by the body is critical for understanding muscle-tendon function, jointspecific contributions and energy-saving mechanisms during gait. Yet, we found that when we sum empirical jointand segment-level measures of work that they fail to capture substantial positive work performed by the body. For example, 25% of the total positive work that we know is perfor...

objectives: investigating the effect of endurance training program onthe gait pattern of non-active elderly people. methods & materials: this study has been done by a semi-experience method with 23 old men and women by the average and standard deviation of 70/50±6/9 years old (n=14 people of exercise group, n=9 people of control group). the exercise group took part in this program for eight wee...

Biomechanical analysis of gait is commonly used in physiotherapy. Ground reaction forces during phases one element kinetic analysis. In this article, we analyze if the MoveSole® smart insole valid and accurate equipment for measuring ground clinical StepLab a mobile measurement system instant underfoot force measurements gait. Unique electromagnetic film (EMFI) based sensor technology printed e...

[Purpose] The purpose of this study was to investigate the effects of treadmill training on functional recovery by analyzing the ankle joint as well as the knee and hip joints with 2D video analysis during gait by rats with sciatic nerve injury. [Subjects and Methods] Twenty-four male Sprague-Dawley rats were used in this study. The sham group (SG) received only a sham operation without any sci...

The ZeroG provides dynamic body weight support (BWS) using a harness while individuals with mobility impairments (e.g., spinal cord injury) ambulate overground. Muscle activity during locomotion using this device was studied in 13 nondisabled adults (age 23.8 +/- 2.7 yr). Electromyography (EMG) recordings were collected from tibialis anterior (TA), medial gastrocnemius (MG), rectus femoris (RF)...
