If you’ve been dealing with low back pain that just won’t go away, your doctor may recommend physical therapy. For many people, PT is one of the most effective ways to relieve pain, improve mobility, and prevent future flare-ups.
But what actually happens in physical therapy? What can you expect at your first visit, and how does it help? This guide breaks it down step by step so you feel informed and confident about getting started.
Why Physical Therapy Helps Low Back Pain
Physical therapy focuses on improving how your body moves. Instead of just treating pain in the moment, PT addresses the root causes — like weak muscles, poor posture, or limited flexibility.
Research shows that exercise-based physical therapy reduces pain, improves function, and lowers the risk of chronic back pain [1][2]. For many, it’s as effective as medications, and it avoids the risks of surgery.

When to Consider Physical Therapy
Physical therapy may be recommended if you have:
Back pain lasting more than a couple of weeks
Recurring flare-ups that interfere with daily life
Pain after an injury
Conditions like herniated discs, arthritis, or spinal stenosis
For more detail on underlying causes, see common conditions behind back pain: herniated discs, arthritis, and more.
The First Appointment: What to Expect
Your first session is about understanding your unique situation. A physical therapist will:
Review your medical history — past injuries, activity level, daily habits.
Ask about symptoms — where pain is located, what makes it better or worse.
Perform a physical exam — testing strength, flexibility, posture, and movement.
Set goals — reducing pain, restoring mobility, or preventing future problems.
This evaluation helps create a tailored treatment plan.
If your pain is severe, or you’re not sure PT is right for you, see when to see a doctor for back pain.
Types of Treatments You Might Receive
1. Exercise Therapy
The foundation of most PT programs.
Stretching: Improves flexibility in muscles like hamstrings and hip flexors.
Strengthening: Core and back exercises to support the spine.
Stabilization: Movements that improve balance and control.
See best exercises for a healthy spine for examples you may recognize from PT sessions.
2. Manual Therapy
Hands-on techniques where the therapist mobilizes joints or soft tissues. This may include gentle stretching, massage, or spinal mobilization.
Studies show manual therapy combined with exercise can be especially effective [3].
3. Posture and Movement Training
Therapists teach you how to sit, stand, lift, and move in ways that reduce stress on your spine. For more, see how posture affects your back health.
4. Modalities
Some PT clinics use tools to help reduce pain:
Heat or cold packs
Electrical stimulation (like TENS units)
Ultrasound therapy
These may provide short-term relief, but the real long-term benefit comes from exercise and movement strategies [4].
5. Education
A major part of PT is learning how to manage back pain yourself. Therapists provide tips on ergonomics, daily activity, and prevention strategies so you stay confident outside the clinic.
For at-home adjustments, see ergonomic hacks for home and office.
What Progress Looks Like
Relief isn’t always instant. Many people start noticing changes after a few sessions, with steady improvement over several weeks.
Short-term: Reduced pain and stiffness, better confidence moving.
Mid-term: Stronger muscles, improved posture, less frequent flare-ups.
Long-term: Lower risk of recurrence and better overall mobility.
Research suggests that combining supervised PT with home exercises leads to the best outcomes [5].
Your Role in Recovery
Physical therapy is not passive. Success depends on practicing exercises at home and making lifestyle adjustments. Therapists often assign homework — stretches, strengthening routines, or posture checks — that are just as important as in-clinic sessions.

How Long Does PT Last?
It varies depending on the severity and cause of your back pain. Some people need just a few weeks of sessions, while others benefit from ongoing support over months.
On average:
Acute pain: 4–6 weeks of therapy.
Chronic pain or complex conditions: Longer programs with regular reassessments.
Your therapist will adjust the plan as you progress.
Preventing Future Flare-Ups
One of PT’s biggest benefits is prevention. By building strength, flexibility, and awareness, you reduce your chances of recurring pain.
Strategies often include:
Continuing home exercises
Practicing good posture
Staying active (walking, swimming, cycling)
Managing stress — see mind-body connection between stress and low back pain
Getting enough restorative sleep — see the role of sleep in back health
What the Research Says
Exercise-based physical therapy is strongly supported as first-line treatment for low back pain [1].
Manual therapy plus exercise improves outcomes more than either alone [3].
Education and self-management strategies significantly reduce recurrence [6].
Long-term benefits are greatest when patients stay active outside therapy sessions [5].
When Physical Therapy Isn’t Enough
Most people benefit from PT, but it’s not always the complete solution. If symptoms don’t improve, other treatments may be considered, such as medications or procedures.
In rare cases, surgery may be needed — usually for issues like severe herniated discs or spinal stenosis. Your therapist and doctor can help determine if that’s necessary.
Bringing It All Together
Physical therapy is one of the safest, most effective ways to treat low back pain. By focusing on movement, posture, and strength, PT not only relieves pain but also helps prevent it from coming back.
Your therapist will tailor a plan to your needs, but your role is just as important — staying consistent with exercises, making ergonomic adjustments, and managing stress.
