MS 2502 Digital Muscle Stimulator Machine (Dual Channel)

Professional-Grade Neuromuscular Stimulation & Rehabilitation

Re-activate dormant muscle groups, combat disuse atrophy, and accelerate injury recovery with the MS 2502 Digital Muscle Stimulator Workstation. Specifically engineered for physical therapy centers, sports medicine clinics, and professional rehabilitation environments, this microcontrolled device provides advanced targeted electrical stimulation across two fully independent output channels.

Featuring an intuitive tactile control console and a versatile array of therapeutic currents, the MS 2502 offers clinicians precise control over muscle re-education, twitch testing, and localized circulatory enhancement.

Modality Breakdown: Complete Motor Nerve Management

The MS 2502 comes pre-configured with four primary therapeutic waveforms, allowing practitioners to customize rehabilitation protocols for both innervated and denervated muscle tissue:

1. Galvanic Current (Continuous Direct Current)

• Delivers a constant, unbroken flow of unidirectional electrical current.

• Primarily utilized for iontophoresis (driving therapeutic topical medications deep into tissue layers) and assessing nerve denervation.

• Promotes deep localized thermal effects to maximize regional blood circulation.

2. Interrupted Galvanic (Int. Galvanic)

• Features adjustable pulse profiles delivered at targeted intervals (1 Hz, 2 Hz, and 4 Hz).

• Calibrated specifically for stimulating denervated muscles (muscles lacking active nerve supply) to help maintain muscle fiber viability and prevent severe fibrotic tissue buildup during nerve regeneration.

3. Faradic Current

• Produces short, asymmetrical pulses designed to elicit smooth, tetanic contractions in innervated muscles.

• Ideal for structural diagnostic testing, treating muscle fatigue, and mapping specific motor points.

4. Surge Faradic Current

• Modulates the Faradic waveform by gradually ramping the current intensity up and down.

• Mimics natural voluntary muscle contractions, making it exceptionally comfortable for patients during active muscle re-education, strength training, and localized edema (swelling) reduction.

Key Features & Control Panel Breakdown

1. Dual-Channel Independent Operation

The workstation features an isolated layout for CH-1 and CH-2, enabling multi-point muscle targeting:

• Tactile Intensity Switches: Tap the digital (+) and (-) membrane keys to smoothly scale the current up or down based on real-time patient feedback.

• LED Intensity Bars: Integrated multi-segment bar graphs provide an instant visual representation of active output levels for both channels.

• Output Ports: Features heavy-duty, color-coded terminal sockets positioned on the front panel to guarantee secure, stable lead wire connection during treatment loops.

2. Centralized Mode & Timer Hub

• Waveform Selectors: Flanking the center panel, dedicated diagnostic graphic blocks (Galvanic, Int. Galvanic, Faradic, Surge Faradic) show the precise pulse structure being applied.

• Parameter Selector Tree: Cycle through modes and time allocations seamlessly using the central TIMER (T) and MODE (M) buttons. High-visibility LEDs confirm active settings from 5 to 30 minutes.

• Auto-Stop Safety Gate: Features a dedicated STOP indicator node. The system automatically cuts off all outgoing current the second the digital timer runs out, protecting the patient from over-stimulation.

Technical Specifications

Primary Clinical Applications

• Post-Surgical Muscle Re-Education: Perfect for re-activating the quadriceps following ACL surgery or total knee replacements, helping patients restore regular voluntary motor control.

• Prevention of Disuse Atrophy: Safely stimulates immobilized limbs during long-term splinting or cast immobilization to preserve muscle mass, tone, and volume.

• Peripheral Nerve Injury Rehab: Aids in treating conditions like Bell’s Palsy, foot drop, or radial nerve injuries by keeping the muscle fibers responsive while the nerve pathway recovers.

• Edema & Swelling Management: Uses Surge Faradic modes to create a rhythmic “muscle pump” effect, accelerating lymphatic drainage and clearing inflammatory fluid from swollen joints.

Why Choose the MS 2502 Digital Unit?

Clean Hybrid Interface

By removing traditional mechanical dials that wear down over time, the MS 2502 utilizes long-lasting, flat membrane switches. This flat-surface design is highly texturized, intuitive to use, and incredibly easy to sanitize between patient rotations.

Robust Clinical Shell

Housed in an impact-resistant, angled white desktop enclosure, the device offers optimal screen visibility when placed on a clinical cart or treatment table. A rear-mounted master power toggle switch and standard IEC power socket ensure safe, stable clinical operation under continuous use.
