XFT-2003EA Hand Rehab System — sEMG-Triggered FES Wearable Rehabilitation

The XFT-2003EA Hand Rehab System is the second-generation wearable Functional Electrical Stimulation (FES) rehabilitation device. Where conventional hand rehabilitation devices passively drive hand movement, the XFT-2003EA takes a fundamentally different and more neurologically sophisticated approach: it reads the patient's own voluntary muscle activity via surface electromyography (sEMG) and uses that biological signal to trigger precisely timed electrical stimulation — creating a closed-loop therapeutic loop that activates the brain and central nervous system in a natural, intention-matched way.

The result is a hand rehabilitation system that works with the patient's nervous system rather than around it — producing superior neuroplasticity outcomes for patients with hand dysfunction caused by stroke, hemiplegia, traumatic brain injury, incomplete spinal cord injury, multiple sclerosis, and wrist drop due to central nervous system injuries.

5 Working Modes — Full Rehabilitation Protocol Coverage

The H2 APP provides five distinct working modes, each serving a specific clinical purpose within the hand rehabilitation protocol:

1. NMES Mode (Neuromuscular Electrical Stimulation) Pure electrical stimulation delivered without requiring EMG triggering. Suitable for patients in the earliest recovery stage with no detectable voluntary motor signal. NMES maintains muscle tone, retards atrophy, increases blood circulation, and reduces muscle spasm — providing therapeutic benefit even before any voluntary movement is possible. NMES is the starting point for patients who cannot generate a measurable EMG signal.

2. ETS Mode (EMG-Triggered Stimulation) The H2's core rehabilitation mode. Electrical stimulation is triggered only when the patient generates a sufficient voluntary EMG signal, ensuring that every stimulation event is paired with an intentional motor command from the patient's brain. This intentionality is what makes ETS therapeutically superior to passive NMES for neuroplasticity-based motor recovery — the brain learns that its commands produce the intended movement outcome, reinforcing the damaged neural pathway with each successful cycle.

3. PAS Mode (Paired Associative Stimulation) A specialised mode that combines EMG monitoring with precisely timed transcutaneous electrical stimulation in a protocol designed to induce long-term potentiation (LTP) — a neurological process that strengthens specific neural connections through repeated paired activation. PAS leverages Hebbian plasticity principles to produce durable changes in motor cortex excitability and corticospinal pathway strength, going beyond the training effect of ETS alone.

4. EMG Mode (Biofeedback) A dedicated EMG monitoring and biofeedback mode without electrical stimulation. The device monitors and displays the patient's sEMG signal in real time, showing maximum, minimum, and average EMG values in objective, quantifiable terms. EMG mode is used for evaluation — establishing baseline muscle activity levels and detection thresholds — and for biofeedback training where patients learn to consciously control and improve their muscle recruitment patterns by watching their EMG signal on screen.

5. Game Mode (Interactive Rehabilitation) Patients control smartphone or iPad game functions by volitionally contracting specific muscles of the hand and forearm — turning muscle activity into game controls. The games are clinically designed to require the specific voluntary movements that are therapeutic for hand recovery, making high-volume repetitive practice enjoyable, engaging, and self-directed. Game mode activates brain cells, improves cognitive-motor coordination, and dramatically improves patient motivation, engagement, and willingness to train for extended daily sessions.
