Recovering from a stroke : help robots

Recovering from a stroke : help robots
When recovering after a stroke robots can be useful to physical therapists, claim Japanese scientists.

study was conducted among 56 people, in which one side of the body was paralyzed.All patients had a stroke in the previous 4-8 weeks and at the start of the study proceeded to the rehabilitation program.

Every day working with them occupational therapist, whose task was recovering from a stroke movement skills in the affected limbs, and the development of the paralyzed muscles.

doctor conducts a standard exercise for 40 minutes.During the sessions, patients had to re-learn how to perform daily activities such as dressing, and working with various objects.

recovery after stroke: a robot physiotherapist

32 patients every day for 40 minutes further engaged in a specially designed simulator called Reo Therapy System.

Paralyzed patient's hand placed on the arm extending from the robot body.Together with her arm movements performed in consecutive different directions on a pre-made program.

results of experimental studies have shown that exercise with the help of a robot helped patients recover impaired muscle function more efficiently and in greater quantities than usual physiotherapy.

Dr. Kayoko Takahashi, lead developer of the new device from the Department of Occupational Therapy at the Kitasato University East Hospital (Kanagawa, Japan), explains the findings follows.

possible that in humans, unlike doctors, robots can retrain the patient more effectively.This is due to the fact that the movement of the patient's limb on the machine keypad clearer and more precise and repeated with the same frequency that allows you to restore the disturbed neural connections in the brain tissue.Therefore, physical activity improves paralyzed limbs.

The results of the studies were assessed on a scale of measurement of motor activity of the shoulder, forearm and the entire upper extremity (36-point scale Fugloy-Meier).Patients who coached the robot can better restore motor skills.None of the patients complained of discomfort during exercises with the robot, while in group sessions with a physiotherapist common complaint was pain.

Prospects treatment with

robots inventors have yet to answer many questions.For example, when recovering from a stroke, you need to seek the help of a robot, how much should last for one session and what is the total duration of treatment session, for a long time whether to save the effect of exercise?

addition, too early to speak about economic efficiency of leche, although its health benefits is undeniable patients themselves.

However, we can already say that the ultimate cost of stroke vosstanovleniyaposle using the robot will be much smaller, and its efficiency - higher than in the classroom with your doctor.

researchers emphasize that robots can never completely replace the human and standard therapy, but only complement it for best results.

results of its work, the Japanese scientists presented at the International conference on stroke, which was held in February 2011 in Los Angeles (USA), under the leadership of the American Stroke Association.
