Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a push-up power-assisted feedback trainer. Background Art

[0002] Push-up training is a common and simple physical exercise method. Persistent push-up training can produce a good exercise effect on the upper body muscles such as the arms, shoulders, chest, back and waist. At present, due to various reasons, hemiplegic patients are becoming younger. For young hemiplegic patients, appropriate push-up training movements can exercise the affected limbs and waist, abdomen and chest muscles of the patients, thereby alleviating the symptoms of the patients, improving the patients' self-care ability, and enabling the patients to gradually achieve recovery.

[0003] Hemiplegic patients can usually support themselves on one side. Due to insufficient strength and other reasons, they need to lie on an auxiliary training device when exercising to assist the patients in exercising. However, the existing push-up assisting device has a simple structure and only has a spring to provide assistance. For hemiplegic patients, their rehabilitation exercises need to be gradual. In the early stages, it is difficult to lift the body for exercise if the exercise relies entirely on arm strength and the assistance of springs, and the effect of the exercise is not obvious, which may cause patients to resist the rehabilitation exercises. In addition, during the rehabilitation exercise process, if the training device can provide real-time feedback on the patient's training results so that doctors, family members and patients can obtain relevant information about the training, it will not only be convenient for doctors to adjust the training intensity and treatment plan according to the training information, but also enable patients to feel the training effect more intuitively, stimulate the patient's will to exercise, and improve the effect of rehabilitation exercises.
