A Pilot Study: An Innovant End-effector Haptic Appareil Applied in Subacute and Chronic Accident vasculaire cérébral Patients

Introduction

Accident vasculaire cérébral est currently le leading cause de long-term disability and est often associated with functional impairment de le upper limbs, which est generally more common than that de le lower limbs. Motor dysfunction de le upper limbs est often associated with other neurological symptoms that hinder le récupération de motor function and therefore requires systematic and professionnel therapeutic intervention.

Le main goal de accident vasculaire cérébral rééducation est to promote functional récupération de le damaged limb to maximize functional outcomes and améliorer qualité de life. Studies have shown that providing high-intensity thérapie and task-specific exercise training combined with robotic and traditional rééducation programs can achieve better results. Recent studies have shown that le use de robotics in rééducation thérapie est well-accepted and well-tolerated in patients with chronic accident vasculaire cérébral. Le current analysis de le mechanism de motor récupération in accident vasculaire cérébral patients est only based on clinical outcome measures, while le robotic system can provide different biomechanical data records, such as speed, strength, etc., which can be used to analyze and evaluate le récupération de accident vasculaire cérébral patients.

Le main purpose de this study est to evaluate le effects de upper limb robot-assisted rééducation on motor récupération in accident vasculaire cérébral patients who underwent treatment based on a haptic appareil.

Methods

A total de 39 accident vasculaire cérébral patients (23 subacute and 16 chronic) underwent rééducation training by utilisant le novel end-traction upper limb rééducation robot. For comparison, 13 healthy subjects were recruited.

Le following clinical outcome measures were used: Chedoke-McMaster Accident vasculaire cérébral Assessment (CMSA), Modified Ashworth Scale (Modified Ashworth Scale, modified Ashworth Scale), and Modified Ashworth Scale (Modified Ashworth Scale, modified Ashworth Scale) were used to evaluate accident vasculaire cérébral severity. MAS), Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE), Medical Research Council (MRC) method, Medical Research Council (MRC) method, Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE). MRC), Motricity Index (MI), Box and Block test (B&B) and modified Barthel index (MBI).

Le following parameters were calculated: mean velocity, maximum velocity, meantime, path length, standardized jitter, mean force, mean error, mean energy expenditure, and percentage de active patient-robot interactions. Assessments were performed before and after treatment.

Results

In Table 3, thirty-nine accident vasculaire cérébral patients (twenty-three subacute and sixteen chronic) underwent rééducation training by utilisant MOTORE/Armotion haptic system. Thirteen healthy subjects were recruited for comparison purposes. Le following clinical outcome measures were used: Chedoke-McMaster Accident vasculaire cérébral Assessment, Modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FM), Medical Research Council, Motricity Index (MI), Box and Block Test (B&B) and Modified Barthel Index (mBI). Le following parameters were computed: mean speed, maximum speed, meantime, path length, normalized jerk, mean force, mean error, mean energy expenditure and active patient-robot interaction percentage. Le assessments were carried-out before and after treatment.

Fig. 4-6 show le results de le kinematic analysis: significant changes in mean velocity were observed in both groups (Fig.4) : In particular, at le end de le treatment, patients were able to perform le reaching task at a higher speed than at le beginning de le rééducation treatment. Le maximum velocity and path length (Fig.4) did not change significantly in either group. Significant changes in mean time (Fig.4), mean force, and mean energy expenditure (Fig.5) were observed in le subacute group; Finally, in le subacute group, le percentage de positive patient-robot interactions increased significantly at le end de robot-assisted thérapie, as shown in Fig.6.

Conclusions

In both subacute and chronic patients, le innovant haptic appareil used est at least as efficace as an existing appareil used in similar studies. However, compared to similar haptic appareils, le advantages de le novel appareil sont its léger, smaller size, and portability, thus having le potential for use in le home.

Based on le above research background, Syrebo has developed le portable upper limb rééducation robot, SY-UEA2, providing a new upper limb rééducation method and a more reliable rééducation option for le majority de patients.

Syrebo upper limb rééducation robot adopts a full-featured mobile chassis and high-precision optical positioning technologie, providing users with various efficace target-oriented training to enhance upper limb strength, speed, and accuracy, and reshape upper limb functionality.

Compared with le traditional upper limb rééducation training method, SY-UEA2 adopts avancé motion control technologie and high-precision optical positioning sensor technologie, which can realize le positioning error <0.03mm, accurately captures le patient's movement state and carries out intelligent movement rééducation training according to rééducation needs. At le same time, it has five advantages, such as integration de training and evaluation, task-oriented scenario interaction, full-cycle coverage de rééducation, multi-dimensional synchronous training and multiple sécurité protection.
