A prototype for a walking assistance apparatus for the elderly or motor palsy patients was developed, using a novel spatial parallel link mechanism. The flat steps of the apparatus move in parallel with the ground; the apparatus can support entire leg alignment (including soles) and assist; walking behavior at ankle, knee and hip joints simultaneously. By using a flexible link, constructed of stainless...
In this study we describe walking speed estimation method using only temporal parameters of gait. Further, this method can be adopted for automatic speed adaptation during walking on treadmill which is useful for gait rehabilitation process and also for navigation in virtual reality environment. The proposed speed estimation method is based on two temporal parameters during stance phase: time duration...
Regaining the ability to walk after a stroke is a major rehabilitation goal. Rehabilitation strategies that are task oriented and intensive can drive cortical reorganization and increase activity levels in people after a stroke. This paper describes a novel, wearable device for use with such rehabilitation strategies. The device is based on the combination of a smartphone and in-shoe sensors, and...
We are developing a measurement device by means of which gait information can be obtained that cannot be obtained by existent devices. We are also evaluating the effectiveness of the device in rehabilitation programs. The final goal of our work is to realize a space where patients can execute their rehabilitation routines at any time. In this paper, we report the outline of our novel measurement device...
The stroke is one of the most prevalent health and well being risks world-wide. In stroke patient rehabilitation, retrieving the ability to walk is an important goal. In addition to that, the gait should be sufficient for independent mobility in the community, thus eliminating the risk of more severe immobilization, falls and health deterioration. In this paper the requirements of a comprehensive...
It is important that we analyze walking stability of physically unimpaired persons as one aspect of preventive medicine. There are many cases of unstable walking even if people think they are in good health. It is considered that if they continue to walk unstably, this may cause lower-back pain or knee pain; this burden also exerts bad influences upon other physical parts. We assessed walking stability,...
Practice, effort and specificity have been proved as the major principles for gait rehabilitation. The best way to improve performance of a motor task is to execute that specific motor task again and again. To assure the consistency of a task specific repetitive gait rehabilitation training with accuracy, from both the patient and therapist ends for a long training session, automated gait trainer...
Conventional gait rehabilitation treatment does not provide quantitative and graphical information on abnormal gait kinematics, and the match of the intervention strategy to the underlying clinical presentation may be limited by clinical expertise and experience. In this paper, a mobile gait monitoring system (MGMS) is proposed, which helps patients self correct their gait without restriction of time...
Gait analysis is important element in therapy and rehabilitation of hemiplegic individuals. We developed a simple, portable sensor system, which can be used for recording of gait signals, as well as for estimation of important gait parameters like joint angles, ground reaction forces, and various temporal parameters. In order to assess robustness of the system in everyday use in different environmental...
This paper analyzes the human motion analysis system for lower limbs rehabilitative robot. In this paper, we focus on the design of motion analysis system for gait analysis during human's walking. The system was designed as a different sensors combination consisting of two gyroscope-chips that measure two-direction rotational velocities of the foot and a two-axis accelerometer-chip that can output...
