Case study



RSD - Knee Injury, Fractured Vertebra: L4 Pars Defect

  • INTERX RESULTS: After 30 InterX treatments, patient reported 4+ prescription medications to none, minimal to no pain or discomfort (pain level of 8 decreased to 0 out of 10), pain induced pseudo seizures stopped after first InterX treatment, limited mobility and wheel chair use to active lifestyle. Discontinued medication and treatment costs of $500 per month. $52,000 spent on nerve block injections and seizure emergency costs prior to InterX treatment, but $30,000 spinal cord stimulator surgery avoided. As of 2018, patient remains 100% Opioid Free since 2005 InterX treatment (13 years).

  • PRIOR RESULTS: Patient reported these symptoms, medications, treatments and a pain level of 8 prior to InterX treatment:

    • Symptoms: Seizures, Severe Pain, Difficulty Walking

    • Medication: Hydroprofen Vicoprofen, Neurontin, Skelaxin

    • Treatment: Back Surgery, Nerve Block and Seizure Treatment

Linsey's story

Linsey Heidelberg was enjoying her teenage years and looking forward to her first step of independence, turning 16 years old. In addition to being a vibrant leader and National Honor Society member, Linsey loved gymnastics and was a three-time All-American cheerleader.

In August 2004, Linsey suffered a knee injury. After two months of physical therapy, she returned to cheerleading. One week after returning to the squad, Linsey suffered a fractured vertebra (L4 Pars Defect) performing a stunt at practice. This serious injury resulted in a back brace and later surgically implanted wires and screws to stabilize her back. Although Linsey had begun to recover from these two accidents, increasing pain in her leg and back caused her condition to deteriorate until she began to suffer seizures, sometimes lasting up to six hours, due to the intense pain.

In May 2005, Linsey was finally diagnosed with Complex Regional Pain Syndrome (CRPS), also known as Reflex Sympathetic Dystrophy (RSD), an incurable chronic neurological syndrome affecting millions worldwide. CRPS/RSD is characterized by severe pain, swelling, marked skin color and temperature changes, excessive sweating, movement disorders and extreme sensitivity to touch. For the next six months, this condition controlled Linsey's life.

Previous Therapies

Linsey relied on a number of medications often simultaneously, including steroids and sympathetic nerve blocks. "Nothing took the pain away," Linsey said. She attempted biofeedback and aquatic therapy with little relief and any kind of weight-bearing physical therapy was impossible because of the pain.

She was always in terrible pain. Standing would cause her leg to turn a deep purple in color from the knee down and her foot was completely numb. Even walking using crutches meant dragging her limp foot behind her. The constant threat of seizure brought on by intense pain confined Linsey to a wheelchair.

Despite a total of 15 seizures, Linsey tried to continue with her education until August 2005, when she was officially forced to withdraw from school. The only option left to combat the pain seemed to be to implant a spinal cord stimulator in her back, which was scheduled for the end of September 2005.

Treatment and Results

Linsey's spine specialist had heard of the InterX and suggested she try this therapy. "I was immediately amazed by the sensations I could feel in my foot," Linsey said, after her first treatment in September 2005.


After nine treatments, she was able to bear weight on her injured leg with the help of crutches.

After 14 treatments, Linsey was off of all medications and walking without crutches or a knee brace. Her range of motion has been completely restored and she is now able to have weight-bearing physical therapy to strengthen her muscles. She was able to return to school and normal social activities. Her scheduled spinal surgery was cancelled, and Linsey has not had a single seizure since the day of her first InterX treatment.

Though there is no recognized cure for CRPS/RSD, thirteen years later in 2018 Linsey reports that she has been symptom and medication free since 2005. Until she was pain free, she managed her pain at a by self-treating one to three days per week. As a teenager Linsey said she wanted to volunteer at the hospital where she was treated, and eventually become a physical therapist for children and treat with InterX. She now has a PhD in Physical Therapy and work with infants.

"InterX therapy gave me back the most important things in my life," Linsey said. "In fact, it gave me my life back."

Linsey's 2018 Statement on InterX Treatment Results: "Immediately my pain seizures stopped. I stopped all medication. I slowly was able to re-enter society. I am now a full time physical therapist for birth to 3 year olds. My day consists of 7 patients where I sit on the floor, kneel, walk, run, and jump. I have no lingering signs of CRPS and it does not limit my function in any way."
