Error Enhancement of the Velocity Component
Error Enhancement of the Velocity Component in the Course of Stroke Patients' Reaching Movements - A Pilot Study
The purpose of this pilot study was to explore the impact of enhancement of the velocity component error in the course of reaching movements of the impaired/hemiparetic limb in an acute stroke subject. We hypothesized that the method would shift velocity profiles toward the optimal, resulting in a reduction in error. A prototype robot. This robotic device system has a two-dimensional motor, basic measurement capacities, and a robotic arm which is engaged to the subject's upper-limb in a sitting position.
The enhancement of the velocity component error would shift velocity profiles toward the optimal, resulting in a reduction in error.

Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Improvement in Average Movement Trajectory Error From T1 to T2
Délai: The outcome was assessed at the begining of the rehabilitation (T1) and about 5 weeks later at the end of rehabilitation (T2).
|
While reaching, people have typical movement pattern of trajectory, moving the end-effector (hand) in straight line.
The abnormal motor control after a stroke may cause these patients to deviate from this pattern.
Our robotic device enabled us to measure the magnitude of the deviation from the optimal profile of healthy people.
This was followed by a calculation of the average error the paricipants made in each treatment session.
So we finally recieved a score of the average magnitude of trajectory error the participants made through a treatment session.
Each treatment seesoin composed of about 100 reaching movements.
The outcome measure expresses the change in the movement error from T1 to T2.

The outcome was assessed at the begining of the rehabilitation (T1) and about 5 weeks later at the end of rehabilitation (T2).

|
Fugl-Meyer Assessment Score
Délai: The measured assessed at the begining of the rehabilitation (T1) and about 5 weeks later at the end of the rehabilitation (T2).
|
The Fugl-Meyer assessment score (FM) is a zero (disabaled function) to 66 points (high level of function) scale that evaluates the level of the motor impairment of the upper extremity, in stroke patients.
|
The measured assessed at the begining of the rehabilitation (T1) and about 5 weeks later at the end of the rehabilitation (T2).
