AI Technical Summary
Existing finger rehabilitation training tools, such as finger grip rings and finger grip balls, are not very effective for patients with weak muscles, making it difficult for them to complete the exercises.
A finger strength rehabilitation electrotherapy training device was designed, which combines a finger grip strength trainer and an electrostimulation circuit. The device applies electrical stimulation to the fingers during exercise through electrode pads to enhance finger muscle contraction. It includes a boost circuit, a control circuit, and a power supply circuit, and uses an asynchronous boost converter and a Bluetooth SOC chip for control and current regulation.
Even if the patient has weak muscles, it can help complete grip strength training movements, improve the training effect, and promote local blood flow and the removal of metabolic products through electrical stimulation, thereby promoting tissue repair and fatigue recovery.
