In the previous studies, contradictory results were reported on walking symmetry. The walking symmetry is important in the study of the evolution of bipedalism and gait therapy. This study investigated the effects of laterality and walking speed on gait symmetry during three conditions of walking on a treadmill, namely pushing while walking, walking with arm-swing, and walking while holding on a handlebar...
People with motor impairments often need adaptation of input devices to interact with surrounding people and home-appliances via communication aids and environmental control systems. During the adaptation, a body part to be used, a device to be activated, its specific location, and a posture to use it should be decided by assessing accuracy and speed of motions. Additionally, the strength and frequency...
Human foot is a complex musculoskeletal system. As it is impossible to directly measure the force of muscle attaching with limbs, a new quantitative method for dynamics analysis of human ankle muscle forces is presented by using the AnyBody Modeling System and a developed wearable motion and ground reaction force (GRF) sensor system. The sensor system can be used to continuously measure human motion...
Muscle function assessment is important for diagnosing muscular disorders, developing treatment plans, and tracking patient progress over time. The muscle force assessment system (MFAS) can provide quantitative results versus the traditional qualitative results that are obtained from manual tests. A new MFAS was developed for measuring force in the tibialis anterior muscle in response to electrical...
Prolonged static standing caused less freedom to move around and rest the muscles. This lack of flexibility in choosing body position contributes to health problems. It will accelerate fatigue besides discomfort, aching feet and swelling on leg. The aim of this study is to investigate the muscle activity and body discomfort while standing. Twelve subjects (seven females and five males) participated...
This paper proposes a multi-sensor data fusion technique to determine the complex interactions between the sensory, muscular and mechanical components of the human locomotor systems (neuromechanics). We investigated the use of an array of accelerometers, rate gyroscopes, force plates and electromyogram for the assessment of x-y-z components of the hip, thigh, shank and foot acceleration and velocity...
Idiopathic toe walkers are children whose heels do not touch the ground during walking, but who do not have any neurological deficit to explain this. The stretch reflexes for these children are normal, so that the toe walking appears to be voluntary. These children often suffer social problems. Many of these children who are not treated and some during treatment, are likely to develop a dasiaBouncy...
