Device Story

TL250 is a multi-modal electrical stimulator providing Interferential, Muscle, High-volt, Low-volt, and Microcurrent stimulation. Device delivers electrical pulses to patient tissues via electrodes to achieve therapeutic effects including pain management, muscle re-education, and circulation improvement. Operated by healthcare professionals in clinical settings; device settings adjusted based on specific therapeutic goals (e.g., spasm reduction vs. pain relief). Output affects clinical decision-making by providing non-pharmacological pain management and physical rehabilitation support. Benefits include improved patient mobility, reduced muscle atrophy, and prevention of post-surgical complications like venous thrombosis.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Multi-modal electrical stimulator (Interferential, Muscle, High-volt, Low-volt, Microcurrent). Class II device. Operates via electrical pulse delivery to patient tissues. Technical specifications and materials not detailed in provided documentation.

Indications for Use

Indicated for patients requiring muscle spasm relaxation, prevention of disuse atrophy, local blood circulation improvement, muscle re-education, range of motion maintenance/increase, postsurgical calf muscle stimulation to prevent venous thrombosis, and management of chronic, intractable, post-traumatic, or post-operative pain.
