摘要
在康复医学领域，手部功能障碍患者的康复训练是恢复手部活动能力的关键环节。对于脑卒中、外伤等导致手部运动功能受损的患者而言，科学、规律的康复训练能有效促进神经功能修复与肌肉力量恢复，但传统康复训练依赖人工辅助，存在训练强度难以精准控制、训练模式单一、患者依从性低等问题，严重影响康复效果。因此，研发一种可灵活调节、多模式控制的手部康复训练仪器十分必要。
本设计提出一种基于 STM32F103C8T6 单片机的手部康复训练仪。系统主要功能包括：通过三个按键可选择缓慢式、匀速式、加强式三种康复速度，以及单指控制（指定单根手指启动或停止）、五指轮流（模拟抓握依次开合）两种康复模式，并实现康复启动与停止控制；通过 SU-03T 语音识别模块，支持语音指令控制康复速度、模式及启停；借助 OLED 显示屏实时显示当前康复模式、目标手指及康复时长；通过蓝牙模块与手机端连接，实现远程控制康复参数及启停操作。
该手部康复训练仪的作用在于，为手部功能障碍患者提供了一种便捷、灵活的康复训练工具。通过多方式控制与参数调节，满足不同患者的个性化康复需求，提升训练的科学性与趣味性，助力患者高效完成康复训练，加快手部功能恢复进程。

Design of a Hand Rehabilitation Training Device Based on STM32
Abstract
In the field of rehabilitation medicine, rehabilitation training for patients with hand dysfunction is a key link in restoring hand movement ability. For patients with impaired hand motor function caused by stroke, trauma, etc., scientific and regular rehabilitation training can effectively promote nerve function repair and muscle strength recovery. However, traditional rehabilitation training relies on manual assistance, which has problems such as difficulty in precise control of training intensity, single training mode, and low patient compliance, seriously affecting the rehabilitation effect. Therefore, it is necessary to develop a hand rehabilitation training instrument with flexible adjustment and multi-mode control.
This design proposes a hand rehabilitation training instrument based on STM32F103C8T6 single-chip microcomputer. The main functions of the system include: three buttons can be used to select three rehabilitation speeds (slow, uniform, and enhanced), and two rehabilitation modes (single-finger control: specifying a single finger to start or stop, five-finger rotation: simulating grasping and opening in turn), and realize rehabilitation start and stop control; through the SU-03T speech recognition module, it supports voice command control of rehabilitation speed, mode and start-stop; real-time display of current rehabilitation mode, target finger and rehabilitation duration by OLED display; connection with mobile phone through Bluetooth module to realize remote control of rehabilitation parameters and start-stop operations.
The function of this hand rehabilitation training instrument is to provide a convenient and flexible rehabilitation training tool for patients with hand dysfunction. Through multi-mode control and parameter adjustment, it meets the personalized rehabilitation needs of different patients, improves the scientificity and interest of training, helps patients complete rehabilitation training efficiently, and accelerates the process of hand function recovery.
