Wireless Surface Electromyography

FREEEMG: Wireless Surface Electromyography System

BTS FREEEMG is the industry reference in wireless surface electromyography (sEMG). Featuring ultra-miniaturized probes weighing only 10 grams with variable geometry clips, FREEEMG eliminates cumbersome cables to provide absolute freedom of movement. From clinical gait labs to swimming pools (H2O waterproof edition) and dynamic athletic fields, FREEEMG captures muscle timing, activation envelopes, and neuromuscular fatigue with scientific fidelity.

Probe Weight

10 Grams

Ultra-lightweight wireless sensors that do not affect natural patient motor mechanics.

Channel Scalability

Up to 32 Channels

Simultaneous acquisition from bilateral muscle chains and agonist/antagonist pairs.

High-Resolution

16-bit / 4 kHz

Pristine raw EMG signal capture without loss of low-amplitude motor unit potentials.

Battery Endurance

Up to 10 Hours

Continuous acquisition on a single charge with magnetic wireless charging dock.

Technology & Hardware Architecture

Sensor Ergonomics

Zero Cable Freedom & Variable Geometry

Wireless active probes attach directly to standard disposable electrodes. Variable clip geometry accommodates any muscle group from small facial muscles to vastus lateralis.

✓
Active On-Probe Amplification: Signal is amplified directly at the electrode site, completely eliminating cable motion artifacts.

✓
Variable Geometry Probes: Patented flexible design adapts to inter-electrode distances from 15 mm to 30 mm.

✓
On-Board Memory: Stores data internally if patient moves temporarily beyond wireless receiver range.

Specialized Applications

H2O Waterproof Probes for Hydrotherapy

The specialized FREEEMG H2O version allows clinical electromyography inside hydrotherapy pools and aquatic rehab environments.

✓
Submersible Enclosure: Hermetically sealed casing designed for chlorinated and salt-water therapy pools.

✓
Hydrodynamic Attachment: Custom waterproof bi-adhesive patches keep probes firmly affixed during movement.

✓
Post-Surgery Aquatic Care: Objectively quantify early muscle firing patterns in low-gravity water environments.

Clinical Efficiency

Practical, Portable & Instant Biofeedback

FREEEMG requires no dedicated laboratory space. With its plug-and-play USB receiver, clinicians can record muscle activity anywhere—bedside, clinic, gym, or field.

✓
Auditory & Visual Biofeedback: Real-time patient feedback curves accelerate neuromuscular re-education.

✓
SENIAM Protocol Compliant: Pre-set anatomic electrode placement guides built directly into software.

✓
Automated MVC Normalization: Instant %MVC (Maximum Voluntary Contraction) normalization calculations.

Clinical Software & Protocol Modules

BTS EMG-Analyzer

Comprehensive filtering, RMS calculation, FFT frequency spectrum analysis, fatigue index, and muscle co-contraction ratio plots.

Automated Clinical Reporting

Generates objective, color-coded clinical summaries comparing muscle firing patterns against normative baseline databases.

Clinical Applications & Research Specialties

Neurological Rehabilitation

Hypertonia, spasticity management, motor relearning after stroke, and cerebral palsy.

Orthopedic Physical Therapy

VMO/VL imbalance in patellofemoral pain, rotator cuff activation, and lumbar muscle retraining.

Sports & Ergonomics

Muscle fatigue onset monitoring, sports technique optimization, and occupational posture analysis.
