Parkinson disease (PD) is one of the most common neurodegenerative diseases. Its main clinical manifestation is movement disorders. The study of innovative objective methods for the diagnosis and rehabilitation of movement disorders in PD is relevant and in demand taking into account the slowly progressive course of the disease and the complex set of symptoms that subsequently forms a characteristic movement pattern. This article provides an example of a personalized rehabilitation assessment of biomechanical manifestations of the gait function of a patient with exacted diagnosis, stage 3.5 PD according to Hoehn and Yahr, by means of the method of three-dimensional motion video analysis using the Vicon Motion Capture Systems soft-hardware complex. The patient has postural and gait disorders. This method was applied after a rehabilitation course based on the activation of lifting the foot from the support surface (“back push”). Changes in the tempo and rhythm parameters of gait in a patient with PD in comparison to a healthy person were revealed: acceleration of walking pace with shortening of the length of single and double step, a decrease in the time of limb advancement, acceleration of the moment of heel rise and a decrease in walking pace. Analysis of the locomotion also revealed a decrease in the amplitude of flexion-extension in the coxofemoral joint, knee joint and tibio-tarsic on the side with more pronounced Parkinsonism. Insufficient knee flexion and hip extension, excessive dorsal flexion of the foot with insufficient plantar flexion were noted. Revealing the last features of locomotion in a particular case allows one to make a plan for a targeted personalized rehabilitation program for a given patient. Thus, the method of three-dimensional video analysis is a valuable diagnostic tool that makes it possible to objectively assess the existing violations of locomotion and identify the targets of rehabilitation.

The article presents the results of approbation of the complex of objective evaluation of equilibrium and walking functions, including such functional scales as Berg Balance Scale, Dynamic Gait Index, hardware methods of computer stabilometry and laser analyzer of kinematic parameters of walking in groups of patients with poststroke vestibulo-atactic syndrome and hemiparesis syndrome. The proposed complex allows objectively and informatively to assess the state of static and dynamic balance, the risk of falls during walking, changes in the walking pattern in neurological patients. The complex is recommended for the dynamic assessment of patients’ condition during neurorehabilitation.

The method of Constraint-Induced used in the international practice to restore movement in paretic upper extremities. This technique consists in fixing the hands intact, thus all actions necessary, the patient is forced to make the paretic limb. The method is effective, easy to use, doesn’t to require financial expenses. The authors proposed this method of Constraint-Induced to restore movements of the lower limbs in the patients with the syndrome of the central hemiparesis. Increasing the load on paretic limb was achieved due to movement restrictions in the intact limbs. With this purpose the apparatus of the hip joint with a locking arm was used. Movement in the intact limb becomes impossible and paretic leg became the leader. An objective assessment of the functions walk in the study was carried out by means of laser rangefinder method; clinically function walk was estimated by Dinamic Gait Index. Results: in the group of the patients treated by the Constraint-Induced lower limbs method were obtained reliable differences from the group of the patients who received only traditional methods of rehabilitation. This method can be recommended for application in the course of neuro-rehabilitation syndrome of the central hemiparesis.

In this work, we design a wearable system providing control of elbow extension in hemiparetic individuals suffering from the post-stroke effects by stimulation of the triceps brachii muscle. Proposed system uses low-cost consumer grade MEMS accelerometer attached to the individual's forearm and measuring the tilt angle of the forearm relative to the gravity vector. Flexing the elbow above a predetermined threshold flexion angle triggers the triceps electrical stimulation. Among other things, the system is capable to transmit inertial data to external devices via Bluetooth. The operability of the system has been validated with healthy individuals and the results showed its potential as a tool for upper extremity rehabilitation after stroke.
