Cycling is often useful for recovery from hemiplegia. Specific training programs need to follow the guidance of a rehabilitation physician. Cycling usually means that the hemiplegic rehabilitation trainer uses a specialized rehabilitation treadmill to perform bilateral lower limb muscle strength training and periodic movement training. The patient can be bedridden or in a wheelchair, with both lower limbs stabilized on the pedals, and according to the set mode to complete the patient’s active force, machine-assisted full force, machine-assisted partial force training. The more advanced equipment can automatically recognize whether the patient has spasm during the training process, and automatically switch to passive exercise mode to avoid causing muscle damage. Rehabilitation treadmill training helps patients to restore motor control, maintain and increase the range of joint movement, produce functional movement, promote the recovery of brain function and limb motor function, and for hemiplegic patients, it can play a role in lowering spastic muscle tension and improving muscle strength. Rehabilitation training programs for hemiplegic patients need to follow the guidance of rehabilitation doctors to avoid secondary injuries.
