OUR APPROACH
Individualized Care for Complex Pain in Walnut Creek
At Performance Sport Care, we diagnose carefully, treat the multiple drivers of your pain, and measure what actually matters — your return to the life you want in the shortest defensible time.
Why “Find the Root Cause” Is Often the Wrong Question
You've heard it from nearly every chiropractor, physical therapist, and wellness clinic in the country: "We don't just treat symptoms — we find the root cause."
It's a comforting promise. It's also, for most patients with meaningful pain, not how the human body actually works.
The International Association for the Study of Pain (IASP) revised its formal definition of pain in 2020 to explicitly recognize pain as a personal experience influenced by biological, psychological, and social factors. Decades of biopsychosocial research — and any honest clinician's experience with several thousand patients — point to the same conclusion: most persistent or recurrent pain has multiple contributing drivers working together. A disc that's degenerated. A multifidus that's weak. A movement pattern that's compensating. Sleep that's poor. Inflammation that's elevated. Stress that's amplifying the signal. A training load that's outpaced recovery.
Promising to fix "the root cause" sounds confident. In reality, it usually means the clinician hasn't looked carefully enough to see the whole picture.
The Performance Sport Care Method
Three principles guide every plan we build:
1. Diagnose carefully — not generically.
Most of our new patients arrive after months or years of care elsewhere that didn't deliver lasting results. The single most common reason is incomplete diagnosis. Dr. Cancel performs a comprehensive functional and orthopedic examination, reviews any imaging you bring, and identifies which contributing factors are most clinically meaningful for your case — not which ones fit a one-size template.
2. Sequence the interventions intelligently.
Pain relief, tissue healing, and durable strength happen on different timelines and respond to different tools. Reducing pain fast matters for your quality of life. But staying out of pain requires restoring the movement and capacity that allowed the problem to develop in the first place. We sequence the work accordingly.
3. Build durability — don't just deliver short-term relief.
The visit that ends care is the one most clinics don't talk about. Our goal is not to keep you coming back. Our goal is to leave you stronger, better-moving, and more resilient than you were before the injury — so the next decade of your life isn't shaped by recurring pain.
Our Treatment Tools — Each With Real Value, Each With Honest Limits
One of the things that separates our approach from one-size-fits-all care is our willingness to be honest about what each treatment category can and cannot do. Every tool has real evidence behind it. Every tool also has limits. The skill is matching the right tools — in the right order, at the right intensity — to the specific person in front of us.
Sports chiropractic adjustments
What the evidence shows: Spinal manipulation has moderate-quality evidence for reducing pain and improving function in acute and chronic low back pain (Paige et al., JAMA 2017; Coulter et al., Spine Journal 2018) and similar evidence for neck pain. Adjustments are generally safe when delivered by a trained clinician after appropriate examination.
What we add: Targeted, examination-driven adjustments — not a generic full-spine "crack everything" routine. Adjustments are powerful at reducing nociceptive input and restoring segmental motion quickly, particularly in early-stage care.
Honest limit: Adjustments alone rarely produce durable results for patients with weak supporting musculature, deconditioned tissue, faulty movement patterns, or systemic inflammation. That's why we never offer adjustments as a stand-alone solution.
Manual therapy and assisted stretching
What the evidence shows: Soft tissue mobilization, instrument-assisted soft tissue work (IASTM), trigger point therapy, and assisted stretching have consistent evidence for reducing pain and improving range of motion in musculoskeletal conditions (multiple JOSPT and BJSM systematic reviews). Combining manual therapy with exercise produces better outcomes than either alone.
What we add: Hands-on work calibrated to the specific tissue restrictions and movement deficits found on exam — not a fixed protocol applied to every patient.
Honest limit: Manual therapy is most useful as a gateway that reduces pain enough and restores enough motion to make active rehabilitation effective. It is rarely sufficient as a stand-alone long-term treatment.
Supervised strength and movement training
What the evidence shows: Exercise therapy is one of the most strongly supported interventions across the entire musculoskeletal literature. Supervised resistance training, in particular, consistently outperforms unsupervised home programs for adherence and outcomes in chronic musculoskeletal pain, knee osteoarthritis, shoulder dysfunction, and low back pain.
What we add: This is the pillar most clinics skip entirely. Our facility is purpose-built for supervised strength rehabilitation under direct professional oversight — using the same training principles Dr. Cancel developed over 30+ years coaching competitive bodybuilders and athletes. Most of the patients who finally get a durable result with us do so because this component was missing from their prior care.
Honest limit: Strength work is not a quick fix. It takes weeks to months, not days. But it is what closes the gap between "feeling better" and staying better.
Targeted nutritional guidance
What the evidence shows: Nutritional status materially influences systemic inflammation, tissue healing, and pain perception. Omega-3 fatty acid intake has moderate evidence for reducing chronic pain intensity (2025 meta-analysis of 41 randomized controlled trials, n=3,759, showing clinically meaningful effect). Mediterranean-pattern eating, adequate protein for tissue repair, and correction of vitamin D deficiency are each independently linked to improved pain and recovery outcomes.
What we add: Targeted, practical nutritional guidance — not a generic "eat clean" recommendation. We focus on the dietary factors most likely to move the needle on inflammation and recovery for your specific situation.
Honest limit: Nutrition is a contributor, not a cure. It works alongside the physical care, not in place of it. For patients whose pain has a meaningful inflammatory or recovery-deficit component, addressing it can be the difference between plateauing and progressing.
Why One-Size-Fits-All Care Fails
The single most common reason patients arrive at our practice after failed care elsewhere is that they were given a treatment, not a plan. Adjustments. Or exercises. Or a stretching routine. One tool, applied generically, regardless of what their actual examination revealed.
That model fails for a simple reason: if the problem is multifactorial, the solution must be too. A patient with disc-related back pain and weak deep stabilizers and poor sleep and elevated systemic inflammation is not going to get a durable result from adjustments alone, exercises alone, or anti-inflammatory advice alone. They need all four addressed, in the right sequence, with appropriate intensity, by someone who can see how the pieces interact.
That kind of integrated thinking is what we do every day. It is also why we do not promise quick fixes we cannot deliver, and why our patients tend to be the ones who have already tried — and outgrown — narrower approaches.
Time Matters — Why Early, Serious Care Produces Better Outcomes
We take every case seriously, and we move with appropriate urgency. The reason is clinical, not commercial.
When pain persists, three things tend to happen: deconditioning (the protective muscles around the painful area atrophy quickly — multifidus atrophy can become measurable within weeks); movement compensation (the brain builds new motor patterns to protect the painful area, and those patterns become harder to undo over time); and central sensitization (the nervous system's pain-amplification systems become more reactive, making the same input feel worse). Each of these is harder and slower to reverse the longer it has been present.
This is why we work to see new patients quickly, deliver a clear plan on day one, and start meaningful treatment promptly. The best time to address persistent or recurrent pain is earlier, not later.
Who We Help
Performance Sport Care serves the greater Walnut Creek and Contra Costa County community: competitive and recreational athletes, weekend warriors with chronic or recurring injuries, active professionals and retirees who refuse to accept pain as inevitable, and people who simply want to move well and live fully — without surgery or dependence on pain medication.
Most of our patients have one thing in common: they tried other care first, and they're looking for a different result.
What makes Performance Sport Care’s approach different from other chiropractic clinics?
Performance Sport Care rejects the oversimplified “single root cause” framing used by most chiropractic
practices. Most persistent pain is multifactorial — driven by some combination of joint dysfunction, muscle
weakness, movement compensation, inflammation, and prior injury. Dr. Cancel diagnoses each contributing
factor individually and builds a personalized plan integrating sports chiropractic, manual therapy, supervised
strength rehabilitation, and targeted nutritional guidance, rather than applying a fixed protocol.
Why does Performance Sport Care say pain is “multifactorial” instead of having a single root cause?
The International Association for the Study of Pain formally defines pain as a personal experience shaped by
biological, psychological, and social factors. Modern musculoskeletal research consistently shows that
persistent or recurrent pain has multiple contributing drivers working together. Promising patients a single “root
cause” is clinically inaccurate for most cases. Performance Sport Care identifies all the meaningful drivers and
addresses them in the order most likely to produce durable results.
Is there scientific evidence supporting chiropractic adjustments and manual therapy?
Yes. A 2017 JAMA meta-analysis found spinal manipulation produces modest improvements in pain and
function for acute low back pain. Multiple Cochrane and Spine Journal reviews show moderate-quality evidence
for manipulation and mobilization in chronic low back and neck pain. Manual therapy combined with exercise
consistently outperforms either alone. Dr. Cancel applies these techniques based on examination findings, not
as a generic routine.
What role does supervised strength training play in lasting recovery from pain?
Supervised strength and movement training is the rehabilitation component most clinics skip — and the one
most strongly supported by research for durable outcomes. Stronger supporting musculature protects
vulnerable joints, reverses post-injury deconditioning, and prevents re-injury. Performance Sport Care’s facility
is purpose-built for this work, with Dr. Cancel providing direct professional supervision drawn from 30+ years of
competitive strength coaching experience.
How does nutrition affect ongoing pain and inflammation?
Nutrition meaningfully influences systemic inflammation, tissue healing, and pain sensitivity. A 2025
meta-analysis of 41 randomized controlled trials (n=3,759) found omega-3 supplementation produced clinically
meaningful reductions in chronic pain intensity. Mediterranean-pattern eating, adequate protein for tissue
repair, and correction of vitamin D deficiency are each independently linked to improved outcomes.
Performance Sport Care provides practical, targeted nutritional guidance as part of comprehensive care.
How quickly should I seek care for ongoing or recurring pain?
Earlier is better. Persistent pain drives three reversible-but-time-sensitive changes: protective muscles atrophy
within weeks (multifidus atrophy is well documented), the brain builds compensatory movement patterns that
become harder to undo over time, and the nervous system’s pain-amplification systems become more reactive.
Each of these is faster and easier to address sooner. Performance Sport Care works to see new patients
promptly and start meaningful treatment on day one.
Why do so many of Performance Sport Care’s patients arrive after failed treatment elsewhere?
Most patients who arrive at Performance Sport Care after failed care elsewhere share one experience: they
received a treatment — adjustments alone, or exercises alone, or stretching alone — instead of an integrated
plan. Single-tool care fails for multifactorial problems. Dr. Cancel’s comprehensive diagnosis and integrated
treatment of chiropractic, manual therapy, supervised strength rehabilitation, and nutritional guidance is
specifically built to resolve cases that narrower approaches could not.
How does Dr. Cancel’s sports chiropractic background benefit non-athlete patients?
Sports chiropractic emphasizes accurate diagnosis, active rehabilitation, measurable outcomes, and return to
full function — standards developed for athletes but valuable for any active person. Dr. Cancel applies the
same diagnostic rigor and progressive rehabilitation methods to retirees, working professionals, and weekend
warriors. The result is care that aims at restoring real-world capability, not just temporary symptom relief.
If you’ve tried other care and you’re looking for an honest, individualized plan — schedule a consultation. Dr. Cancel will take the time to understand your specific case, identify the contributing factors that actually matter, and tell you what we believe we can do.
