Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical supplies, and in particular relates to a lower limb muscle strength training device for bedridden people. Background Art
[0002] Muscular atrophy is a progressive skeletal muscle cell degeneration disease. When protein synthesis and degradation are unbalanced, muscle atrophy occurs. Clinical manifestations include muscle volume reduction, strength loss, and functional decline. It is a common complication in orthopedics and is also secondary to sepsis, cancer, heart failure, chronic arthritis, and other diseases. Studies have shown that the skeletal muscle weight of the elderly aged 60 to 70 years old is reduced by 25-30%, and the skeletal muscle weight decreases more with age, which is closely related to muscle atrophy in the elderly.
[0003] Resistance exercise is the most common exercise therapy for promoting muscle hypertrophy and increasing muscle strength. At the same time, exercise can promote blood circulation and prevent the formation of lower extremity venous thrombosis. In bed rest experiments, it was found that resistance training largely preserved or improved the structure and function of muscles, affecting capillary content, enzyme activity, mitochondrial regulatory factors and other aspects, improving muscle material and energy metabolism, and thus partially maintaining the cross-sectional area or volume of muscles.
[0004] In clinical practice, lower limb muscle strength training is often performed on bedridden patients through abduction, adduction, dorsiflexion and plantar flexion. This training method can not only prevent lower limb muscle atrophy, but also prevent the formation of lower limb venous thrombosis in long-term bedridden patients. Elastic bands and manual abduction, adduction, dorsiflexion and plantar flexion are routinely used to train lower limb muscle strength for bedridden patients. However, currently, there is no dedicated training device for functional training of the above four movements in clinical practice. Therefore, a sports device specifically for bedridden patients to perform lower limb functional training is needed.
