Roscoe Onyx K4 Wheelchair with Swing-Away Footrests

This lightweight, yet high strength wheelchair is extremely versatile. It features upholstery and seat extensions built in to adapt easily to the individual needs of the patient. The functionality and superior value of this wheelchair makes it ideal for those looking for a chair with high performance at a moderate price.

The 16” wide seat easily adjusts in depth from 16” to 20” on the built-in upholstery extension and seat rail, requiring no further kits or upholstery. The seat and back upholstery features a flame-retardant, heavy-gauge nylon that also resists bacteria and mildew. If a seat cushion will be used, the padded, flip-back arm rests can be adjusted. Adjustable angle seat back and caster forks makes patient comfort a priority.

Long lasting reliability and performance in the wheels comes from the precision sealed wheel bearings, in both the front and back wheels. The composite 24” mag style wheels feature maintenance-free and lightweight urethane tires with a quick-release function. The rear wheels also feature wheel locks that are easily engaged with a push-to-lock function. The front wheels also have a three-height, adjustable angle caster forks to provide for more patient comfort.

The footrests swing away allowing for easy access for the patient entering and exiting the wheelchair. It also improves ease of use for caregivers assisting patients.

This chair comes with a five year warranty on the cross braces and the frame and a 90 day warranty on all other components.

Transcutaneous Electrical Nerve Stimulation (TENS)

TENS is a non-invasive, drug free method of controlling pain, which uses tiny electrical impulses sent through the skin to nerves in order to modify your pain perception. In most people it is effective in reducing or eliminating the pain.

Electronic Muscle Stimulation (EMS)

EMS works by sending electronic pulses to the muscle(s). This is achieved by sending low frequency electric pulses through muscle tissue causing them to gently contract. In this way the muscles are passively exercised and blood flow is increased

Galvanic Stimulators

Galvanic Stimulators use direct current, which creates an electrical field over the treated area. The positive pad works like ice, causing reduced circulation to the area under the pad. The negative pad works like heat, causing increased circulation.


IF sends small comfortable electrical impulses through your skin to work on deeper tissue stimulation. The sensation works to prevent pain signals from reaching the brain.


Infrared Light Therapy help the body by delivering specific light waveforms that increase circulation. Increasing circulation helps promote healing, lessen swelling, and helps in reducing pain.


Portable Ultrasounds give advanced pain relief using sonic stimulation of soft tissue cells. They generate pulsed, high frequency sound waves, which travel deep into the tissue, generating vasodilation. This helps increase blood flow to the treated area.


Russian stimulation uses medium frequencies to provide stimulation to muscle groups. This is used to reduce muscle spasms as well as for muscle strengthening. This method was created to produce maximal muscle strengthening effects.

Micro Current

Microcurrent Therapy uses extremely small amounts of electrical current (millionths of an amp) to help relieve pain and heal soft tissues of the body. The electrical current used in Microcurrent Therapy is so small that it is rarely felt.
