The main reason is that the arm of most hemiplegic patients suffers from muscular atrophy in different degrees, and the length of the turning radius of the crank 11 at the side is adjusted to be the lowest, which is beneficial to gradually drawing the arm suffering from muscular atrophy and relieving the muscular atrophy symptom.
Before a hemiplegic patient goes out, the brake rod of the adjustable physiotherapy hand tricycle is moved to a brake state, then the hemiplegic patient sits in the seat, ties the safety belt, uses the healthy arm to enlarge the wrist tightening ring 1126, uses the healthy hand to hold the affected wrist, passes the affected hand through the wrist tightening ring 1126, is put on the crank 11 with the affected hand fixing band 1123, then tightens the hand back tightening band 1125 and the wrist tightening ring 1126, fixes the affected hand on the crank 11 with the affected hand fixing band 1123, then loosens the brake rod, uses the healthy arm to shake the other crank 11, then the hemiplegic patient can go out, uses the healthy arm to control the direction and output the power, uses the healthy foot to control the brake pedal, uses the healthy arm to drive the affected arm to rotate, tries and experiences the affected arm to assist in controlling the direction step by step,
when the robot moves to a flat and few-person road, the healthy arms are taken away firstly, and on the premise of ensuring safety, the robot tries to move forwards under the action of inertia by only using the diseased arms to control the direction.
In order not to affect the blood circulation of the affected hand, the dorsal tightening strap 1125 and the wrist tightening ring 1126 should be loosened every half hour, or every hour, and the affected hand should be massaged with healthy hands for 5 minutes.
