“…The existing lower limb rehabilitation robots include the single weight support robot, the pedal robot, the bed robot, as well as the exoskeleton robot. The weight support robot mainly aims to reduce the weight of patients, such as the US Kine Assist [3] and Japanese robotics [4]. The instance of Pedal‐type robots including the German Gait Trainer [5–7], Haptic Walker [8], Gait Master [9], Chengdu University [10], and Harbin Engineering University [11] are trapped in large volume and loss of the automatic detection system.…”

“…In addition to these orthoses, DC motor-actuated lower-extremity orthoses, developed specifically for use with paraplegic individuals, include Ekso exoskeleton (Ekso Bionics), ReWalk (Argo Medical Technologies), the Vanderbilt exoskeleton (Farris et al 2011). Some of the relevant research projects for similar rehabilitation purposes were the LOPES (lower-extremity powered exoskeleton) (Veneman et al 2005), and a 3 degrees of freedom walker system to assist people in the daily activities associated with standing-up, sitting-down and walking (Chugo et al 2007).…”

A method for early detection of the initiation of sit-to-stand posture transitions

A powered lower extremity orthotic brace can potentially be used to assist frail elderly during daily activities. This paper presents a method for an early detection of the initiation of sit-to-stand (SiSt) posture transition that can be used in the control of the powered orthosis. Unlike the methods used in prosthetic devices that rely on surface electromyography (EMG), the proposed method uses only sensors embedded into the orthosis brace attached to the limb. The method was developed and validated using data from a human study with 10 individuals. Each human trial included different sets of sitting, standing and walking activities originating from various initial postures. Features from the sensor signal were extracted and aggregated in lagged epochs to incorporate the time history. Principal component analysis (PCA) was used to reduce the feature set. The principal components were then used in a leave-one-out manner to train a linear support vector machine (SVM) classifier to perform early detection of the SiSt posture transition. The proposed method achieved the sensitivity of 100% and the specificity 92.94% of trials without false positives. The average detection time (DT) of 0.1341 ± 0.3310 s following the start of transition demonstrated early recognition of the initiation of SiSt transition.

This paper is concerned with the problem of improvement model for the omnidirectional rehabilitative training walker and tracking control. The aim of the study is to obtain a model that closes to actual walker by considering motor rotation character. An asymptotically stable controller was gotten that can ensure tracking on a training path planned by a physical therapist. The controller that can satisfy asymptotic stability is obtained by constructing the Lyapunov function. The simulation results confirm the feasibility and effectiveness of the designed scheme and indicate the walker can ensure tracking motion by using the improved model.Index Terms -omnidirectional rehabilitative training walker, tracking control, improvement model, asymptotical stability
