Transcutaneous neurostimulator Stim2Go

for peripheral nerve stimulationfor myostimulationfor sensory nerve stimulation

Product overview
Stim2Go is a portable neurostimulation system for non-invasive Functional Electrical Stimulation (FES), Neuromuscular Electrical Stimulation (NMES) and Transcutaneous Electrical Nerve Stimulation (TENS). App-controlled, it delivers device-independent hybrid assistance to amplify patient movement during rehabilitation. Preconfigured and custom programs support motor function recovery, muscle re-education and pain management.

Hybrid Assistance
Provides multi-channel FES support for cyclic motion trainers and other rehabilitation devices without requiring a technical device interface. Assistance adapts to patient capability and rehabilitation phase to amplify volitional movement.

Assisted Training Options

• Assisted cycling (lower limb FES)
• Assisted upper-extremity cycling
• Grasping and reaching training
• Targeted muscle training
• Pain relief (TENS protocols)

Sensor Function
A built-in inertial sensor captures patient motion in real time. Motion-based biofeedback triggers stimulation patterns to support and automatically adapt assistance to the patient’s movement.

Clinical quote
“With the sensor function, the movement can be captured in real time, and the support of the patient´s movement is easily adapted.” — Dr. Thomas Schauer, Scientific Advisor PAJUNK®

Stim2Go overview
The system package includes the stimulator, 2- and 5-channel cables, adapter cable 1:2, charging cable, strap and strap holder, and a power supply with EU/US/UK adapters. The device is rechargeable and optionally wearable.

Features & advantages

• Portable design: compact, lightweight and optionally body-wearable.
• Up to 5 independent stimulation channels for multi-site therapy.
• Adjustable long pulse duration (up to 750 µs) to reach deeper neural structures and accommodate high BMI patients.
• Compatible with ValuTrode® cloth electrodes; in-app wizard for electrode placement and selection of size/shape; electrodes reusable for one patient.
• Augmented reality (AR) support for electrode placement guidance.
• Custom therapy programs: freely programmable sequences, app-based storage and stimulator-independent program export.
• Interactivity: group therapy and telemedicine features; therapist assignment of custom programs and account roles with configurable rights.
• Collaboration options (license required): shared programs and aggregated patient statistics across therapist groups.
• Functional support: manual app triggers or motion-triggered FES via the inertial sensor for upper and lower limb patterns.

Indications for use
As a powered muscle stimulator

• Relaxation of muscle spasms
• Prevention or retardation of disuse atrophy
• Increasing local blood circulation
• Muscle re-education
• Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis
• Maintaining or increasing range of motion

As a transcutaneous electrical nerve stimulator (TENS) for pain relief

• Symptomatic relief and management of chronic, intractable pain
• Adjunctive treatment in post-surgical and post-traumatic acute pain management

As a biofeedback device

• Support for muscle re-education using motion-based feedback

As a functional neuromuscular stimulator

• Assists relearning of voluntary motor functions of the extremities

Important note on movement-based biofeedback
Movement-based biofeedback requires an active range of motion (ROM): volitional movement causing a change in limb inclination of at least 10 degrees to trigger motion-based patterns.

Stim2Go App
System operation, program creation, assignment and account management are handled via the Stim2Go App. The app stores programs, manages therapist accounts and enables group-therapy and telemedicine workflows.
