CPM and Ancillary Services

Biomatrix is committed to assisting our patients throughout their entire rehabilitation process. To that end, we offer a broad range of services outside of the orthotic and prosthetic field. Continuous Passive Motion Therapy (CPM Services),  Cold-Compression Therapy, Bone Growth Stimulation, and Electrotherapy are among the variety of services we offer to help move our patients forward.

Continuous Passive Motion Services

Biomatrix is proud to be the largest comprehensive provider of CPM rehabilitation services in Michigan.  Our inventories exceed 500 therapeutic rental devices; all designed to provide passive motion therapy for the hand, knee, hip, shoulder, elbow, wrist, and ankle.  We offer home or in-hospital delivery of CPM devices throughout all of Michigan and Northern Ohio. 

A CPM device is a machine designed to move joints constantly and gently during therapy to prevent stiffness, inflammation, decrease pain and increase range of motion.  Medical evidence indicates that in many cases early motion increases range of motion and decreases stiffness, inflammation and pain.  Some of the design features are listed below.

  • All devices feature a natural, anatomical motion that increases patient compliance and decreases joint stress, pain, edema, and soft tissue contractures
  • Adjustable speeds, synchronized motion, and set-up modes to provide precise custom therapy options
  • Variable settings for force and pause with programmable treatment plans
  • Patient lock-out feature
  • Patient compliance monitor

Cold-Compression Therapy


VPULSE improves patient outcomes, reduces the total cost of the orthopedic episode, and increases patient satisfaction.

 VPULSE helps patients achieve complete, comfortable recoveries through delivery of three distinct therapies:

  • Rapid impulse calf compression to help prevent Deep Vein Thrombosis (DVT)
  • Motorized cold therapy to help reduce operative site discomfort and inflammation
  • Wound compression to further help reduce operative site inflammation and edema

Polar Cube Cryo

Polar Cube Cryo-Therapy System

The Polar Care Cube Cold Therapy System is simple and reliable. Its easy to use, compact design makes it great for clinic, hospital, and home use. With the addition of ice and water, your patients will enjoy 6-8 hours of effortless cold therapy. Proper use requires an insulation barrier between the pad and the patient’s skin.

Bone Growth Stimulators

Cervical-Stim® Osteogenesis Stimulator

Cervical-Stim is the only osteogenesis stimulator approved by the U.S. Food and Drug Administration (FDA)  as a noninvasive, adjunctive treatment option for cervical fusion. The device uses pulsed electromagnetic f ield (PEMF) technology to increase fusion success in patients at high risk for non- fusion. With an overall clinical success rate of  84 percent, Cervical-Stim increases fusion success significantly by 22 percent when used adjunctively to surgery. 

  • The only osteogenesis stimulator approved by the FDA for use in cervical fusion1 
  • Delivers broad PEMF treatment coverage for multilevel fusions1 
  • Works effectively when worn over clot hing or bracing 
  • Lightweight, all-in-one unit with no cords allows unrestricted patient mobility during treatment  
  • Built-in daily  monitoring software to track patient compliance

Cervical Stim
Spinal Stim

Spinal-Stim® Osteogenesis Stimulator

Spinal-Stim has high success rates for spinal fusion. With an overall clinical success rate of 92 percent, Spinal-Stim provides a 36 percent increase in lumbar fusion success when used adjunctively to surgery.  Spinal-Stim is also the only osteogenesis stimulator approved as a non-surgical alternative for treating failed lumbar fusions.

  • High success rates  for spinal fusion  (92 percent when used adjunctively to surgery) 
  • Only U.S. Food and Drug Administration (FDA) approved osteogenesis stimulator for non-surgically treating pseudarthrosis 
  • Pulsed electromagnetic f ield (PEMF) treatment signal covers 360 degrees, up to five levels of fusion 
  • Works effectively when worn over clothing or bracing 
  • Lightweight, all-in-one unit with no cords allows unrestricted patient mobility during treatment  
  • Built-in daily  monitoring software to track patient compliance

Physio-Stim® Osteogenesis Stimulator

Physio-Stim provides a safe, non-invasive option for treating fractures that are difficult to heal. With an overall clinical success rate of 80 percent (up to 88 percent for fracture gaps less than 3mm), Physio-Stim has high success rates for treating nonunion fractures.  The device assists in fracture healing by delivering a pulsed electromagnetic field (PEMF) signal to the targeted fracture site.   

  • High clinical success rates (80 percent overall, up to 88 percent for gaps less than 3mm) 
  • Delivers broad PEMF treatment coverage around the fracture site 
  • Can be worn with internal and external fixation 
  • Can be worn over casts (no windowing required) 
  • Lightweight, all-in-one unit with no cords allows unrestricted patient mobility during treatment 
  • Built-in daily  monitoring software to track patient compliance 
  • Variety of anatomic models to provide treatment at the targeted fracture site

Physio Stim


Kneehab XP

The Kneehab XP systems utilizes Multipath™ Stimulation Technology to deliver highly focused, accurately coordinated muscle contractions through Neuromuscular Electrical Stimulation (NMES).  Kneehab is commonplace within training rooms of all professional sports team and is an integral part of many elite level athletes post-operative knee rehabilitation.  Some of the benefits are the following: 

  • Early post-surgical quadriceps strengthening and improved post-surgical knee stability secondary to quadriceps strengthening
  • Muscle re-education
  • Maintain or increase range of motion
  • Prevent or retard disuse atrophy
  • Increase blood circulation
  • Relax muscle spasms


TENS – Transcutaneous Electrical Nerve Stimulator

A TENS device is primarily used for managing chronic pain. It utilizes biphasic electrical current delivered through electrodes placed on the surface of the skin to stimulate the sensory nerves to block pain signals and help the body’s endorphin production (its natural analgesic). TENS can be worn all day or on an as needed basis.

Common Uses

– Symptomatic relief and management of chronic (long-term) intractable pain

– Adjunctive treatment for post-surgical and post-traumatic acute pain

  • Chronic & acute pains
  • Back & cervical muscular and disc syndromes
  • RSD
  • Arthritis
  • Shoulder syndromes
  • Neuropathies

INF – Interferential Stimulation

Primarily used to manage deep chronic pain, Interferential current uses very high pulse rate, usually 4001 – 4150 pulses per second. This higher frequency goes through the skin and muscle better than TENS or other modalities, thus can be more effective in pain control. Provides more analgesic, or nerve blocking effect. Device features include adjustable pulse rate, two or four electrode treatment selection, and modulation of pulse rate. Because of such frequency, these devices will require a lot of power, and thus, batteries will not last long. AC Adapters are usually provided with device. Electrode placement should be in an “X” pattern, as the point of intersection provides a third stronger frequency.

Common Uses

  • Symptomatic relief and management of chronic and post-traumatic acute pain
  • Management of post-surgical pain
  • Joint injury syndrome
  • Pre and Post orthopedic surgery
  • Cumulative trauma disorders
  • Inflammatory conditions
  • Pain control of various origins


NMES – Neuromuscular Electrical Stimulation

Primarily used for preventing disuse atrophy (muscle wasting), NMES is stronger than a TENS unit with a wider pulse width to elicit muscle contraction for a period of time. More than just nerve stimulation, muscles are contracted and relaxed on and off to strengthen muscles, increase blood circulation to the area, and/or to reduce edema.  Electrode placement is very important, mostly over motor points or on the belly of muscles.

Common Uses

  • Prevention or retardation of disuse atrophy (wasting of muscle due to lack of use)
  • Muscle re-education, such as after surgery or trauma
  • Maintaining or increasing range of motion or joint mobility
  • Post-orthopedic surgery
  • Joint replacement (i.e. hip, knee, shoulder)
  • Muscle strengthening programs
  • Shoulder subluxation
  • Reduction of muscle spasms
