Should I See a Chiropractor Before Starting Physical Therapy?

There’s a common belief that before beginning physical therapy, you need to “get adjusted” first—as if the body needs to be put back into alignment before real work can begin.

Let’s challenge that narrative. Because the truth is… the body doesn’t work that way.

The Myth of “Perfect Alignment”

For years, pain has been tied to posture, alignment, or something being “out of place.”

But the research doesn’t support that.

There is no single posture that consistently causes pain, and structural findings are often poorly correlated with symptoms (Lederman, 2011; Slater et al., 2019).

In fact:

• Individuals with “poor posture” are often pain-free

• Structural “abnormalities” are frequently seen in asymptomatic populations (Brinjikji et al., 2015)

So, if alignment isn’t the driver… what is?

What Manipulation Actually Does (And Doesn’t Do)

Spinal manipulation—whether performed by a chiropractor or a physical therapist—can absolutely be helpful.

But not for the reasons you might think.

1. Targeted vs. Regional Manipulation

The idea that a provider must manipulate a specific vertebral level to get results sounds precise… but the evidence tells a different story.

Research shows no significant difference between targeted (specific) and non-specific (regional) manipulation in outcomes (Hancock et al., 2007; Kent et al., 2015).

In other words:

• You don’t have to hit the exact spot

• Clinical outcomes are not dependent on segmental specificity

2. The “Pop” Doesn’t Mean Precision OR Correction

That audible cavitation—the “pop”—is often interpreted as confirmation that something specific was corrected...It’s not.

Cavitation is simply gas release within the joint and does not indicate successful targeting or structural change (Cramer et al., 2011).

Additionally:

• Multiple joints may pop during a single thrust

• Popping doesn't correlate with improved outcomes (Flynn et al., 2003)

So Why Do People Feel Better?

This is where it gets a bit interesting—and definitely more powerful.

The benefits of manipulation are primarily neurological, not structural.

The Neurological Effects of Manipulation

Manipulation has been shown to produce measurable neurophysiological changes, including:

• Activation of descending pain inhibition

→ Central modulation of nociceptive input (Bialosky et al., 2009)

• Reduction in temporal summation of pain

→ Decreased central sensitization response (Bialosky et al., 2014)

• Diffuse Noxious Inhibitory Control (DNIC) / Conditioned Pain Modulation

→ System-wide analgesic effect (Coronado et al., 2012)

• Short-term sympathetic nervous system activation

→ Changes in skin conductance, heart rate, and autonomic activity (Budgell & Polus, 2006)

• Regional hypoalgesia

→ Reduced pain sensitivity locally and sometimes remotely (George et al., 2006)

These responses support the idea that manipulation works through modulation of the nervous system, not structural repositioning.

It’s About Input—Not Precision OR Correction

The takeaway?

It’s not about perfectly targeting a joint. It’s about delivering meaningful input to the nervous system.

Manual therapy appears to function as a neurophysiological stimulus, not a biomechanical correction (Bialosky et al., 2009; Pickar, 2002).

Where Physical Therapy Fits In

At 4th Corner, we [re]frame the conversation. Manipulation is not the solution—it’s a tool. A useful one—but it should only be a part of the process.

Because while passive interventions can:

• Reduce pain

• Improve short-term movement

They do not build long-term capacity (Foster et al., 2018).

The Role of Passive vs. Active Care

Passive treatments like:

• Manipulation

• Dry needling

• Massage

…can help calm the system.

BUT active interventions are what drive meaningful, lasting change.

Exercise-based and active rehabilitation approaches consistently demonstrate:

• Superior long-term outcomes

• Improved function and resilience (Foster et al., 2018; Hayden et al., 2021)

So… Do You Need to See a Chiropractor First?

No. You do not need to be adjusted before starting physical therapy. You don’t need to be “put back into place.”

What you need is:

• A clear understanding of your symptoms

• A plan that builds capacity

• A process focused on long-term adaptation

The 4th Corner Perspective

We believe the body is designed to heal. Not through perfect alignment…but through adaptation. Sometimes we use tools like manipulation to help calm things down.

But we don’t stop there. Because the goal isn’t just to feel better temporarily—it’s to move better, perform better, and live better long-term.
