Treadmills have been used in rehabilitation settings to provide convenient protocols and continuous monitoring of movement over multiple cycles at well-controlled speeds for gait and balance training. However, the potential differences in the movement control may affect the translation of the training outcomes to real life over-ground walking (OW). The similarities and differences in the balance control between treadmill walking (TW) and OW have largely been unexplored. The current study bridged the gap by comparing the motions of the body's center of mass (COM) relative to the center of pressure (COP) between TW and OW, in terms of the COM-COP inclination angle (IA) and its rate of change (RCIA)...

While devices which allow scientists to perturb normal walking are becoming increasingly common, postural adaptations to these perturbations have not been fully quantified. One way to quantify postural responses to perturbations are through the assessment of variability of step length and width. In the present study we determined variability of both step length and width while subjects walked under perturbations of varying amplitude in roll, pitch, yaw, anteroposterior, lateral, and combined roll, pitch, yaw directions...

It is well known that proprioception is necessary to maintain balance control. Although proprioceptive exercices have shown to have beneficial effects on balance, the joint position sense is not easy to measure and patient cannot practise self-measurement. This article proposes a new system specifically desinged to allow measure and improve proprioceptive function. This so-called `iProprio' system uses inertial sensors included in a smartphone, wireless communication and voice command to allow joint position sense measurment in autonomous way and provide a configurable vibrotactile biofeedback for end-users at home...

Robotic devices are a promising and dynamic tool in the realm of post-stroke rehabilitation. Researchers are still investigating how the use of robots affects motor learning and what design characteristics best encourage recovery. We present a parallel-actuated, end-effector robot designed to provide spatial assistance for upper-limb therapy while exhibiting low impedance and high backdrivability. A gradient based optimization was performed to find an optimal design that accounted for force isotropy, mechanical advantage, workspace size, and counter-balancing...

This paper describes a wearable sensor that simultaneously measures both shear and orthogonal force. The planar shear sensor is based on inductive coupling between a small target and a series of adjacent coils. Lateral movement of the target changes the coupling between a primary coil and a series of geometrically shaped and scaled sense coils. Design of the sensor and methods for calibration are investigated. The wearable sensor can be used for measurement of in-situ foot loading during ambulation and we postulate that this may be useful for biomechanical analysis including exoskeletons and balance rehabilitation applications...

Falling accidents are costly due to their prevalence in the workplace. Slipping has been known to be the main cause of falling. Understanding the motor response used to regain balance after slipping is crucial to developing intervention strategies for effective recovery. Interestingly, studies on spinalized animals and studies on animals subjected to electrical microstimulation have provided major evidence that the Central Nervous System (CNS) uses motor primitives, such as muscle synergies, to control motor tasks...

Antoine Langeard, Lucile Bigot, Nathalie Chastan, Antoine Gauthier
The lower limb muscle functions of the elderly are known to be preferentially altered by ageing. Traditional training effectively counteracts some of these functional declines but is not always accessible due to its cost and to the accessibility of the training centers and to the incapacities of some seniors to practice some exercises. Neuromuscular electrical stimulation (NMES) could provide an interesting alternative muscle training technique because it is inexpensive and transportable. The aim of this systematic review was to summarize the current evidence on the effect of the use of lower limb NMES as a training technique for healthy elderly rehabilitation...

BACKGROUND: Armeo®Spring exoskeleton is widely used for upper extremity rehabilitation; however, weight compensation provided by the device appears insufficiently characterized to fully utilize it in clinical and research settings. METHODS: Weight compensation was quantified by measuring static force in the sagittal plane with a load cell attached to the elbow joint of Armeo®Spring. All upper spring settings were examined in 5° increments at the minimum, maximum, and two intermediate upper and lower module length settings, while keeping the lower spring at minimum...

BACKGROUND: The Ehlers-Danlos Syndrome (EDS) is a rare disorder affecting the connective tissue. EDS patients may suffer of proprioception and balance impairment but all the studies dealing with such symptoms have been addressed to adult subjects. The Study of such impairment in younger patients may lead to a better awareness of own motor abilities and to a focused rehabilitative intervention. Therefore, our work aims to assess the occurrence of these alterations in a pediatric cohort of EDS patients...

Stroke patients usually suffer from asymmetric posture due to hemi-paresis that can result in reduced postural controllability leading to a balance deficit. This deficit increases the risk of falls, which often makes them dependent on caregivers for community ambulation, thus deteriorating their quality of life. Conventional balance training involves rehabilitation exercises performed under physiotherapist's supervision where the scarcity of trained professionals as well as the cost of clinic-based rehabilitation programs can deter stroke survivors from undergoing regular balance training...

Paraplegic gait orthosis has been shown to help paraplegic patients stand and walk, although this method cannot be individualized for patients with different spinal cord injuries and functional recovery of the lower extremities. There is, however, a great need to develop individualized paraplegic orthosis to improve overall quality of life for paraplegic patients. In the present study, 36 spinal cord (below T4) injury patients were equally and randomly divided into control and observation groups. The control group received systematic rehabilitation training, including maintenance of joint range of motion, residual muscle strength training, standing training, balance training, and functional electrical stimulation...

Individuals with pathological or simulated central visual field loss can be trained to use a preferred retinal locus (PRL) as a substitute for their non-functioning fovea. The functional benefits of a stable PRL are well documented, but little is known about oculomotor adaptations during PRL acquisition or transfer of training to another location in response to real or simulated disease progression. In this study, eight normally-sighted observers were trained to use a pseudo-PRL (pPRL) at one of two locations by guiding an eccentrically placed, gaze-contingent ring over a fixation target...
