Why Is Post-Stroke Hand Rehabilitation So Challenging?

Stroke is one of the most common causes of adult hand dysfunction. Epidemiological data shows that approximately 55%-75% of stroke survivors experience varying degrees of limb dysfunction, with hand dysfunction accounting for up to 80%. Six months post-onset, approximately 65% of patients still experience limited hand mobility, directly impacting basic daily activities such as eating, dressing, writing, and using a mobile phone. 

The hand is structurally complex and functionally refined. Traditional manual rehabilitation training faces inherent limitations - therapist-led one-on-one sessions are constrained in intensity, making it difficult to achieve the high-volume repetition required for neural recovery; patient progress lacks objective data, so treatment adjustments rely heavily on clinical experience; and monotonous repetitive exercises often diminish patient engagement, compromising outcomes.

Pneumatic Hand Rehabilitation Device XY-K-SGN-V is a systematic clinical solution designed specifically to address these challenges.

9 Training Modes - One Device, Full Rehabilitation Cycle

The device offers 9 training modes, logically structured along the rehabilitation continuum - from passive to active to resistive to fine motor - to match different stages of recovery:

• Passive Training - The device drives finger flexion and extension through inflation and deflation, operating in automatic cycles. Maintains joint range of motion while promoting blood circulation and reducing edema.
• Mirror Training - The healthy side wears a data glove to perform movements, while the affected-side glove synchronously follows, promoting cortical activation.
• Voice-Controlled Training - Patients control the device through voice commands such as "hand open," "hand close," "two-finger pinch," and "three-finger pinch," enhancing training interactivity.
• Assistive Training - The device detects the patient's voluntary effort and provides on-demand assistance to complete flexion and extension movements, enabling a "patient-led, device-assisted" training model.
• Active Training (Gaming Mode) - Interactive games such as "Whack-a-Mole," "Flappy Bird," and "Tug-of-War" guide patients to actively perform hand movements, improving training adherence.
• Grip Strength Training - Uses a grip ball for fist, two-finger pinch, and three-finger pinch strength training with real-time feedback.
• Resistive Training - Offers three resistance modes: flexion-extension, flexion-only, and extension-only, to progressively strengthen hand muscle groups.
• Finger Exercise Training - Targets palm opening/closing, finger flexion/extension, and opposition movements for refined coordination.
• Quick Training - One-touch launch of preset protocols, reducing operational steps for routine daily sessions.

Smart Assessment: Making Rehabilitation Progress Visible and Measurable

Rehabilitation cannot rely on "feeling" alone. Patients need to see their progress, and therapists need data to guide clinical decisions.

Grip Strength Measurement

Uses a grip ball to measure the patient's maximum force in fist, two-finger pinch, and three-finger pinch positions. Results are presented as quantitative data and automatically saved.

Opposition Testing

Uses a data glove to assess the patient's completion rate of thumb-to-index, thumb-to-middle, thumb-to-ring, and thumb-to-little finger opposition, evaluating neuromuscular control.

Reporting System

- Assessment reports automatically generated, viewable and printable

- Training reports automatically saved for sessions exceeding 1 minute

- Multi-user electronic records management for departmental use

Pneumatic-Electrical Combination: Coordinated Mechanical and Neuromuscular Stimulation

During the extension phase of passive training, the device can connect via Bluetooth to an electrical stimulation module, delivering synchronized neuromuscular electrical stimulation. Electrodes are placed over the forearm extensor muscle groups to promote wrist extension and finger opening.

Key Electrical Stimulation Parameters:

Note: Electrical stimulation is delivered only during the extension phase (when the hand is opening), with no output during the flexion phase.

Core Specifications

Safety Protection Mechanisms

The device incorporates multiple layers of safety protection:

In the event of power interruption or system fault, the patient simply withdraws their hand from the flexible glove to release the mechanical constraint.

Indications and Contraindications

Applicable Departments: 

Neurology, Neurosurgery, Rehabilitation Medicine, Hand Surgery, Orthopedics, Burn Care, Pediatric Rehabilitation

Indications for Use:

Stimulates finger and wrist joints, promotes physiological circulation of synovial fluid, reduces joint swelling, and prevents or treats reduced joint range of motion, joint stiffness, and venous thrombosis caused by trauma or insufficient movement.

Contraindications - Hand Function Training:

1. Untreated or uncontrolled persistent inflammation

2. Unstable finger or wrist fractures, whether untreated or requiring immobilization

3. Extensive purulent foci, extensive burns, or hemorrhage of the hand

4. Untreated or unprotected infection and skin lesions

5. Severe spasticity

6. Excessively high muscle tone preventing grasp

7. Severe joint deformity of fingers or wrist preventing grasp

Contraindications - Electrical Stimulation:

1. Bleeding tendencies, coagulation disorders, acute purulent inflammation, spastic paralysis, broken skin, malignant tumors, cardiac pacemaker placement, metallic implants, cardiac region, carotid sinus area, severe cardiopulmonary or renal failure, lower abdomen in pregnancy

2. Post-stroke spastic stage; severe cognitive impairment; eye area; unconsciousness; limb joint contractures; abnormal nerve excitability

Frequently Asked Questions (FAQ)

Q1: Can it be used in the early (bed-bound) stage post-stroke?

Yes, upon physician evaluation. The device supports bedside passive training but must be operated by qualified healthcare professionals.

Q2: What are the main advantages over traditional manual training?

Three key advantages: 

• Standardized repetitive training with precisely controlled intensity and duration; 
• Objective data feedback for accurate protocol adjustments; 
• Reduced physical burden on therapists.

Q3: Does training cause pain?

Under normal conditions, no. The flexible glove conforms to the hand contour with adjustable pressure, and intensity is progressed gradually. Any discomfort should be reported immediately.

Q4: How should the glove be cleaned and disinfected?

Wipe with 75% medical alcohol after each patient use and allow to air dry before next use.

Q5: How often should electrodes be replaced?

Electrodes have a 1-year shelf life from the date of purchase; replace after expiration.

Q6: Can the device be used at the bedside?

Yes. The host contains a 22.2V/5.2Ah battery with ≥2 hours of runtime, unrestricted by power outlet location.

Q7: What is the device's service life?

10 years.

Q8: Is the device complicated to operate?

No. The 10.1-inch touchscreen with graphical interface and voice prompts enables quick proficiency after brief training.
