Musculoskeletal pain is one of the most common reasons people seek help from health professionals. Back pain, neck pain, shoulder pain, osteoarthritis, tendinopathy, and other MSK conditions contribute substantially to disability, health-care use, and economic burden. After decades of clinical trials, one conclusion is difficult to ignore: there is no clear universal winner.

Exercise, manual therapy, education, advice, psychological approaches, and surgery can all help, but their average effects are usually modest and broadly comparable. This should not be discouraging. It suggests that MSK care does not need to be framed as a battle between treatment tribes. A better question is not “Which treatment is best for everyone?” but “Which reasonable, evidence-informed option is most appropriate for this person, in this context, at this time?”

This is the idea behind treatment pluralism.

Beyond the Manual Therapy versus Exercise Debate

In physical therapy and manual therapy professions, debates about treatment value often become polarized. Manual therapy is sometimes criticized as passive, outdated, or low value, while exercise is often presented as the more scientifically defensible option.

But this does not reflect how many clinicians actually practise. Most therapists use a mixture of approaches. They educate, reassure, touch, move, coach, progress, modify, listen, and adapt. Manual techniques may reduce pain, calm the system, build trust, or create a window for movement. Exercise may restore confidence, capacity, strength, mobility, or self-efficacy. Education and advice may reshape fear, expectations, and behaviour.

The reality is more complex than the debate. More importantly, the evidence does not support a rigid hierarchy where one broad category of treatment is always superior.

What Is Treatment Pluralism?

Treatment pluralism begins with a simple observation: no single intervention has proven consistently superior for musculoskeletal pain across all patients.

Pluralism does not mean “anything goes.” It does not mean every treatment is equally valid, nor does it excuse exaggerated claims, outdated explanations, or unsafe practice. Rather, it recognises that within a bounded range of safe, plausible, and evidence-informed interventions, there may be several valid routes to improvement.

This also applies to clinicians. One therapist may specialise deeply in exercise rehabilitation, manual therapy, cognitive functional therapy, pain education, or psychologically informed care. Another may work more broadly, drawing from several methods. Both styles can be legitimate if they are transparent, evidence-informed, clinically reasoned, and responsive to the person in front of them.

Similar Effects, Overlapping Mechanisms

Research comparing exercise-based and manual therapy-based interventions often finds similar average effects for pain and function. This does not mean the treatments are identical. They look different, feel different, and may be experienced differently by patients. But similar outcomes suggest they may work partly through shared mechanisms.

Manual therapy may influence pain through neurophysiological responses, changes in sensitivity, expectation, reassurance, therapeutic touch, contextual effects, and natural recovery. Exercise may influence pain through improved capacity, confidence, exposure, changes in threat perception, general health effects, contextual effects, and natural recovery.

In both cases, the specific technique may be only part of the story. The interaction, explanation, expectation, sense of safety, therapeutic alliance, and patient engagement may all contribute to improvement.

Put simply, both manual therapy and exercise can help people with MSK pain, and they may often help through overlapping pathways.

Average Effects Do Not Tell the Whole Story

Clinical trials usually report average treatment effects. These averages are useful, but they can hide large differences between individuals.

One patient may respond very well to strengthening. Another may initially need symptom relief, reassurance, or hands-on care before they feel confident to move. Another may benefit most from education and graded exposure. Another may need support with pacing, sleep, stress, or workplace factors.

This variation is known as heterogeneity of treatment effects. It helps explain why group-level comparisons often show little difference between treatments. Evidence tells us what tends to happen across groups; clinical reasoning helps us decide what may be useful for the individual.

Hedgehogs and Foxes in Therapy

Isaiah Berlin described two styles of thinking: hedgehogs and foxes. Hedgehogs understand the world through one big organising idea. Foxes draw from many ideas and are more comfortable with complexity.

In MSK care, a hedgehog-like therapist may work mainly through a dominant framework, such as exercise rehabilitation, manual therapy, or psychologically informed care. This can be effective when delivered with skill, clarity, and appropriate patient selection.

A fox-like therapist may draw from multiple frameworks, adapting treatment to the patient’s presentation, preferences, goals, beliefs, and context. This may involve combining education, movement, graded exposure, manual techniques, lifestyle advice, and self-management strategies.

Neither style is inherently superior. Problems arise when either becomes rigid or dogmatic. Treatment pluralism allows both to coexist, provided care remains safe, honest, evidence-informed, and responsive to the patient.

What Pluralism Looks Like in Practice

Treatment pluralism means being clear about what we offer and why.

A therapist might say: “I mainly work through exercise and movement coaching, but I will adapt the plan to your symptoms and goals.”

Or: “I use hands-on techniques where appropriate, alongside advice, education, and exercises to help you return to what matters.”

This transparency helps patients make informed choices. It also gives patient preference a legitimate role. Some patients value the calming or reassuring effects of manual therapy. Others prefer the independence of exercise-based care. Some want clear education, confidence-building, or a combination.

When options are safe, plausible, and evidence-informed, these preferences are part of good person-centred care.

Guardrails: Pluralism Is Not “Anything Goes”

Treatment pluralism must remain bounded by evidence, safety, plausibility, and honesty. Interventions should have reasonable support for modest benefit, acceptable risk, and clinical relevance.

Therapists should avoid exaggerated claims, outdated explanations, dependency-based models, and narratives that make patients fragile or fearful. Manual therapy does not need to be justified by claims about “putting joints back in place.” Exercise does not need to be oversold as a universal cure. Education should not become dismissive reassurance. Psychological approaches should not imply that pain is “all in the mind.”

Pluralism requires both openness and discipline. It allows different routes to recovery, but not careless reasoning.

Conclusion

The search for one best treatment for all musculoskeletal pain is unrealistic. Decades of research suggest that several interventions can help, their average effects are often modest and similar, and they may work through overlapping mechanisms.

At the same time, individual responses vary widely. Until we can predict treatment response with much greater precision, therapists need a practical philosophy that accepts uncertainty without abandoning evidence.

Treatment pluralism provides that philosophy. It recognises multiple valid pathways to recovery within clear professional and scientific boundaries. It supports clinician expertise, patient preference, and honest communication. Most importantly, it shifts MSK care away from professional turf wars and back toward the person seeking help.

For therapists, the message is simple: we do not need to prove that one modality is always best. We need to reason well, communicate clearly, stay within evidence-informed boundaries, and help each patient find a credible path forward.
