Chronic Low Back Pain Case Study: Improved Sitting Tolerance and Reduced Lumbar Hypersensitivity After Physiotherapy Care

Peter, a 50-year-old man with a 15-year history of chronic low back pain, right foot numbness and marked lumbar hypersensitivity, was referred to Lifestyle Therapies by a local health provider. His case is a useful clinical example for readers wanting to understand the broader role of magnetic therapy for low back pain as part of a structured physiotherapy management plan.

He was initially referred for InterX therapy, an electrotherapy device used in the management of pain and altered skin conductivity responses. His presentation was complex, long-standing and functionally limiting.

This case study outlines Peter’s clinical presentation, treatment approach and observed outcomes during a course of physiotherapy care that included InterX therapy, hands-on treatment, rehabilitation planning and adjunctive use of a multipolar magnetic device.

Clinical History

Peter first injured his lower back when he was approximately 20 years old. In his thirties, he underwent a laminectomy, followed several years later by a lumbar fusion at L5–S1.

Despite surgery, he continued to experience constant deep pain and numbness into his right foot. He reported that he had not lived a day without pain for many years, and his symptoms had significantly affected his quality of life.

In addition to his chronic low back pain, Peter presented with marked sensitivity over the lumbar spine. He reported that even wearing clothing over the lower back could be unbearable. This sensitivity appeared to follow a previous incident involving a TENS machine and was consistent with features of hyperalgesia, allodynia and central sensitisation.

Peter was also unable to sit in a car for more than one hour without a significant increase in pain.

His main functional goal was very clear: he wanted to return to painting.

Initial Assessment Findings

Peter’s initial assessment identified several findings relevant to both his pain presentation and rehabilitation needs.

These included:

• inhibition of the core muscles
• increased tone through the gluteal muscles
• tenderness to touch through the adductors, iliotibial band and quadriceps
• marked lumbar sensitivity, even with light touch
• elevated InterX readings in the lumbar region at very low intensity
• reduced tolerance to sitting, driving and hands-on treatment

During the initial InterX assessment, readings in the lumbar region were greater than 100 at 2% intensity. This was associated with high sensitivity and pain, even with light touch, consistent with static mechanical allodynia.

Taken together, these findings suggested that Peter’s condition involved more than a local structural back problem. His pain presentation appeared to include a sensitised nervous system response, reduced tissue tolerance and significant functional limitation.

Treatment Approach

InterX therapy was used during the first visit in a chronic pain setting for approximately 15 minutes.

Immediately following this session, Peter was able to tolerate five minutes of massage. This was clinically meaningful because prior to treatment, light contact over the lumbar spine had been highly provocative.

As part of his home management, Peter was also fitted with an OF50-3 Octapolar Q Magnet over the lower lumbar region. This multipolar magnetic device was selected because its size allowed coverage across the lower lumbar segments, including the L5–S1 and L4–L5 region.

The magnet was used as an adjunct to physiotherapy care, not as a standalone treatment. The broader clinical aim was to reduce pain sensitivity, improve tolerance to touch, improve sitting capacity and create a better foundation for rehabilitation.

Early Treatment Response

One week after his first appointment, Peter reported experiencing pain-free moments for the first time in many years.

He also reported improved sitting tolerance during the drive from his home to the clinic, with minimal pain compared with his previous tolerance for car travel.

During the following week, Peter reported extreme disappointment that his symptoms were beginning to return. On review, it was found that the Q magnet had been reattached incorrectly after his wife changed the sports tape. The magnet had inadvertently been turned around, so the flux plate was facing the body, rather than the intended treatment surface.

Once the placement was corrected, Peter reported that his symptoms began to settle again almost immediately.

This was an important clinical observation. Peter had not been aware that the magnet had been reattached incorrectly, yet his symptoms increased while it was incorrectly positioned and they declined again after correct placement was restored. This pattern is less consistent with a placebo-only explanation and suggests that accurate placement was relevant to his clinical response.

In this case, correct magnet orientation and placement appeared to matter. The observation reinforced the importance of careful application when magnetic devices are used as part of a physiotherapy management plan.

Outcome After Seven Sessions

After seven treatment sessions, Peter demonstrated a significant reduction in lumbar hypersensitivity.

He was able to tolerate touch over the lower back more comfortably and could tolerate hands-on treatment such as massage. He was also able to tolerate a much higher InterX intensity than during the initial session.

Most importantly, Peter achieved a meaningful functional outcome: he was able to sit and paint for five hours.

For Peter, this was a major improvement. Painting was not just a hobby; it was the activity he most wanted to return to. The ability to sit for several hours and engage in painting represented a significant change in quality of life.

Clinical Interpretation

Peter’s progress suggests improvement in several clinically relevant areas:

• reduced lumbar tactile hypersensitivity
• improved sitting tolerance
• improved tolerance to manual therapy
• improved response to InterX intensity
• return to a valued functional activity
• increased confidence in movement and daily function

The reduction in pain sensitivity was consistent with improved nervous system tolerance during the course of treatment. While it is not possible to attribute Peter’s progress to one intervention alone, the combination of InterX therapy, carefully selected adjunctive magnetic field application, hands-on treatment and rehabilitation planning appeared to support meaningful clinical change.

This case also highlights the importance of measuring progress through function, not pain alone. Pain-free moments were important, but the more meaningful outcome was Peter’s ability to return to painting for five hours.

Ongoing Rehabilitation

Although Peter made substantial progress, further rehabilitation was still required.

The next stage of treatment focused on improving stability, core strength and longer-term functional capacity. This was important because reduced pain sensitivity can create a valuable opportunity for rehabilitation, but lasting improvement still depends on rebuilding strength, control and confidence over time.

Adjunctive therapies may help create a window in which movement and hands-on treatment become more tolerable. However, rehabilitation remains essential for improving long-term physical capacity.

Clinical Reflection

This case demonstrates that meaningful improvement may still be possible in long-standing chronic low back pain, even when symptoms have been present for many years.

Peter’s presentation involved persistent pain, altered sensation, lumbar hypersensitivity, reduced sitting tolerance and significant quality-of-life impact. Over seven sessions, he experienced reduced sensitivity, improved treatment tolerance and a return to painting.

For clinicians, the case reinforces several important points:

• chronic pain presentations often involve nervous system sensitivity as well as local tissue factors
• tactile hypersensitivity can be a useful clinical marker to monitor
• functional goals should guide treatment planning
• accurate placement matters when adjunctive devices are used
• improvement should be measured by meaningful patient outcomes, not pain scores alone

For Peter, the most important outcome was not simply that his pain changed. It was that he could return to something he valued.

After 15 years of chronic low back pain, being able to sit and paint again represented a meaningful step forward.
