Product introduction
The A5-2 Finger Joint Rehabilitation Assessment System is an integrated assessment and rehabilitation device designed for clinical and outpatient use. Using a soft pneumatic glove combined with surface electromyography (SEMG), the system detects patients' intended hand movements to enable coordinated active and passive training. It delivers objective hand-function metrics and patient management tools to support therapists in tailoring rehabilitation plans and monitoring progress.

Function details

• Patient information management: records gender, age, Brunnstrom stage, glove size, affected side and diagnosis; all assessment and therapy records are automatically saved and archived for longitudinal tracking.
• Quantitative assessment of hand function: per-finger measurement of movement angle and range of motion; automatic generation of visual reports and rehabilitation trend charts to support objective outcome evaluation.
• Intelligent pneumatic-electro-synchronous combined training:
  • Triggered mode: SEMG captures real-time active intent and triggers synchronized pneumatic and electrical assistance for active-plus-passive training.
  • Induced mode: SEMG-based monitoring dynamically coordinates pneumatic and electrical stimulation intensity, adjusting assistance according to patient signals.
• Integrated multi-mode training:
  • Mirror-guided training: camera captures motion from the healthy hand and drives the affected hand to reproduce movements for bilateral coordination and neural reorganization.
  • Passive fine motor training: supports passive practice of tasks such as fist clench, single-finger tapping, finger opposition and pinching.
  • Resistance training mode: soft glove provides bidirectional progressive resistance with five adjustable levels to address strengthening needs.
  • Active and combined training: combines camera and force sensors for active training with scene interaction and game feedback; supports customized protocols.
  • Gamified interactive training: supports camera, SEMG/EMG and grip-force inputs to increase engagement and participation.

Application scenarios

• Orthopedic and postoperative rehabilitation: finger joint injuries and postoperative repair (fractures, dislocations, tendon injuries); joint diseases such as osteoarthritis, rheumatoid arthritis and tenosynovitis.
• Nervous system rehabilitation: central nervous system injuries including stroke, cerebral palsy and spinal cord injury; peripheral nerve injuries (median, ulnar, radial).
• Muscle and tendon rehabilitation: hand muscle atrophy and weakness, finger stiffness and contractures, abnormal muscle tone.
