“…The underlying mechanisms of balance training have been discussed extensively (Taube et al, 2007;Sehm et al, 2014;Ruffieux et al, 2018;Helm et al, 2019). Based on the concept of motor relearning, PBT can provide abundant sensory stimulation and therefore induce the storage of motor program to prevent falling (Kakebeeke et al, 2006). Motor skills, with enhanced neuromuscular control and inter-joint coordination, can be facilitated through repetitive perturbation stimulations Krause et al, 2018).…”

“…Motor relearning is an essential concept in neurorehabilitation (Edgerton et al, 2001;Mulder and Hochstenbach, 2001;Kitago and Krakauer, 2013). In individuals with spinal cord impairment, remaining synapses in neuronal tracts can regenerate due to the plasticity, and the neuron circuitry can relearn motor skills if proper reinforcements were offered (Edgerton et al, 2001;Mulder and Hochstenbach, 2001;Kakebeeke et al, 2006;Kitago and Krakauer, 2013). Therefore, repetitive practice in a task-specific environment can facilitate the reacquisition of a motor skill (Edgerton et al, 2001;Mulder and Hochstenbach, 2001;Kakebeeke et al, 2006).…”

Degenerative cervical myelopathy (DCM) is a common aging condition caused by spinal cord compression. Individuals with DCM often presented with residual balance and functional impairments postoperatively. Perturbation-based balance training (PBT) has been shown to have positive effects on populations with neurological disorders but has yet to be investigated in DCM. The objective of this study was therefore to evaluate the effects of PBT on balance and functional performance in postoperative individuals with DCM. Fifteen postoperative individuals with DCM (DCM group) and 14 healthy adults (healthy control group) were recruited. The DCM group received a 4-weeks PBT using a perturbation treadmill. The outcome measures included mean velocity of center of pressure (COP) during quiet standing; center of mass (COM) variance and reaction time to balance perturbation during standing with forward and backward perturbation; gait speed during level ground walking; Timed Up and Go Test (TUG) and disability questionnaire scores including Visual Analog Scale, Neck Disability Index, and Lower Extremity Function of Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire. The assessments were conducted preand post-training postoperatively for the DCM group but only once for the healthy control group. Significant improvements were observed in the mean velocity of COP, COM variance, reaction time, gait speed, and TUG in the DCM group. Disability questionnaire scores were not significantly different after training in DCM group. For between-group comparisons, significant differences that were observed pre-training were not observed post-training. The 4-weeks PBT is a potential rehabilitation strategy for addressing balance and functional impairment in postoperative individuals with DCM. In addition, the post-training performance in the DCM group exhibited trends comparable to those Frontiers in Bioengineering and Biotechnology | www.frontiersin.org 1 February 2020 | Volume 8 | Article 108Cheng et al.Perturbation Training in Cervical Myelopathy of age-matched healthy controls. Furthermore, the training regimens offer a practical reference for future studies on populations with balance disorders. Future studies complemented with neurophysiological assessments could reveal more information of the underlying mechanisms of PBT.

“…La marche est une fonction complexe qui est organisée hiérarchiquement [1], débutant au niveau spinal et contrô-lée par les structures supérieures, telles le tronc cérébral, les voies extrapyramidales, ainsi que les structures corticales dont le cortex primaire moteur localisé dans le gyrus précentral. Dans ce système hiérarchisé, les structures supé-rieures sont à l'origine de l'initiation du mouvement et les structures inférieures responsables de l'organisation et de l'exécution des mouvements.…”

Lesions of the central nervous system often lead to walking impairments. Primary rehabilitation aims at the improvement of the gait capacity by application of task oriented training regimes utilizing the inherent capability of neural networks for reorganization. However, a sufficient training intensity for enhancement of this neuroplasticity can only be achieved during the inpatient phase, which -due to economical restrictions -is getting shorter and shorter. In the clinical environment complex and expensive robotic devices have been introduced to maintain the duration and the intensity of the training, but up to now only a few exist for continuation of an automated locomotion training at home.Hence this project aims at the development of a compact, modular, individually adaptable motor driven orthosis for home based gait training. In contrast to ergometer or continuous passive motion devices the novel "MoreGait" system is capable of generating the proprioceptive and sensory stimuli in particular the gait-phase dependent loading of the foot soles, which have been identified recently also in humans as key afferent inputs of the spinal gait pattern generator. Artificial pneumatic muscles with excellent weight-to-force ratio have been integrated as actuators for ankle joint and combined hipknee movements. Their inherent low stiffness efficiently supports the safety concept of the device, which is intended to be operated by the handicapped users completely on their own including transfers from the wheelchair. A nonlinear observer based controller has been implemented for the knee joint and a model based feedback controller for the ankle to compensate the highly nonlinear behavior of the mechanical system. For safety reasons a semi-recumbent position of the user has been foreseen, in which a foot loading cannot be achieved by the users' own body weight. Therefore the Stimulative Shoe has been developed on the basis of pneumatically actuated mediolateral bars mimicking the physiological foot loading pattern. The users operate the device via an intuitive user interface and receive feedback about their training activities through a graphical representation of model-based derived joint torques.
