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...
The study of bipedal gait is important for two primary reasons: biomimetic robotics and human gait rehabilitation. Both fields have numerous models describing bipedal locomotion that require a no-slip interaction with the ground for accuracy. This paper presents a low cost wearable sensor system capable of identifying slip in real time, which could afford rehabilitative analysts important information...
This paper presents an approach on measurement of impacts absorption level on legs in a walking situation, by using 3-axis accelerometer sensor attached on three essential part of body. To measure this levels of impact on ankle and waist, developed a microcontroller based portable wireless sensing and data acquisition system. Comparing between, both impacts received at ankle to the impact receive...
The assessment of Ground Reaction Forces (GRF) is important for gait analysis for sports, pathological gaits and rehabilitation. To capture GRF, force plates and foot pressure insoles are commonly used. Due to cost and portability issues, such systems are mostly limited to lab-based studies. Long-term, continuous and pervasive measurement of GRF is not feasible. This paper presents a novel concept...
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...
In this paper a method for footstep detection and gait event identification is presented. A three-axis accelerometer can be mounted on someonepsilas foot to record the acceleration signals produced by their gait. The data can be analysed in real time or after a period of time to identify the gait events and their respective acceleration values. Data analysis consists of signal processing in order...
