01 Product Introduction
The A5-2S Finger Joint Rehabilitation Assessment System is an integrated medical device for objective assessment and combined active/passive rehabilitation of finger joints. The system pairs a soft pneumatic glove with surface electromyography (SEMG) to detect patient intent and deliver synchronized pneumatic and electrical assistance. It includes quantitative hand-function assessment and patient data management to support clinicians in personalizing therapy and monitoring progress.

02 Function Details

• Patient Information Management: Records patient demographics and clinical data including gender, age, Brunnstrom stage, glove size, affected side, and diagnosis. All assessment and treatment sessions are automatically saved and archived to enable individualized plan development and longitudinal tracking.
• Quantitative Assessment of Hand Function: Measures finger joint angles and range of motion for each digit with precision. The system automatically generates visual reports and rehabilitation trend charts to provide objective metrics for outcome evaluation and clinical decision-making.
• Intelligent Pneumatic‑Electro‑Synchronous Combined Training: Triggered mode: SEMG detects active movement intent in real time and triggers synchronized pneumatic and electrical stimulation for combined active+passive rehabilitation. Induced mode: SEMG monitoring enables dynamic adjustment of pneumatic and electrical assistance intensity to provide graded support tailored to patient status.
• Integrated Multi‑Mode Training: Mirror‑Guided Training: camera captures movements of the healthy hand and drives the affected hand to replicate them, promoting neural reorganization and bilateral coordination. Passive Fine Motor Training: supports passive practice of fist clenching, single‑finger tapping, finger opposition and pinching. Resistance Training Mode: soft glove delivers bidirectional progressive resistance with 5 adjustable levels for strength conditioning. Active and Combined Training: combines camera input and force sensors for interactive scenarios and game‑based active training; supports customized programs for individualized progression. Gamified Interactive Training: supports camera, SEMG and grip‑strength inputs to increase patient engagement.

03 Application Scenarios
This system is intended for use in rehabilitation medicine, orthopedics/hand surgery, neurology, occupational injury rehabilitation, geriatrics and related clinical settings. Typical indications include:

• Orthopedic and postoperative rehabilitation: finger joint injuries and post‑operative recovery (fractures, dislocations, tendon repairs); joint diseases such as osteoarthritis and rheumatoid arthritis.
• Nervous system rehabilitation: central nervous system injuries (stroke, cerebral palsy, spinal cord injury); peripheral nerve injuries (median, ulnar, radial nerve lesions).
• Muscle and tendon rehabilitation: hand muscle atrophy or weakness (disuse atrophy, strains/tears), finger stiffness and contractures, abnormal muscle tone.
