Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an arm rehabilitation training device with a stretching exercise function. Background Art

[0002] Neurology is a secondary discipline related to nerves. It does not belong to the concept of internal medicine. The main examination methods include head and neck MRI, CT, ECT, PETCT, EEG, TCD (transcranial Doppler ultrasound), electromyography, evoked potential and blood rheology examination, genetic diagnosis, etc. At the same time, cross-diagnosis and treatment of functional diseases such as neurasthenia and insomnia are carried out with the psychology department; the main treatments include cerebrovascular diseases (cerebral infarction, cerebral hemorrhage), migraine, brain inflammatory diseases (encephalitis, meningitis), myelitis, epilepsy, dementia, metabolic diseases and genetic diseases, trigeminal neuralgia, sciatica, peripheral neuropathy and myasthenia gravis. Neurology patients often show symptoms such as limb weakness. Appropriate rehabilitation training can reduce the sequelae of the disease and maintain the normal function of the limbs.

[0003] Patients' arm stretching exercises are beneficial to arm muscle training, which can prevent muscle atrophy, stimulate limb nerves, and help patients recover. Existing arm rehabilitation exercise devices still have the following shortcomings when used: First, some patients do not have the ability to actively exercise their arms in the early stages of rehabilitation. If leg and arm exercises can be combined, not only can patients with arm dysfunction use their legs to drive their arms for autonomous exercise, but limb training can also improve the effect of rehabilitation; secondly, existing arm exercise devices do not have a massage function, which causes muscle stiffness after exercise, making it difficult to fully stimulate the arm and body muscles, and it is not easy for patients to persist, resulting in unsatisfactory arm rehabilitation training effects.
