How Long Does Physical Therapy Last For Lower Back Pain?

Most people start to feel noticeable improvement within 2 to 4 weeks of beginning physical therapy. A full course of treatment typically lasts between 4 to 8 weeks, with 1 to 3 sessions per week.
The total duration can vary depending on…
- The cause of the back pain (acute vs. chronic)
- The complexity of the condition
- Patient commitment to home exercises
- Progress made during therapy
For more complex or long-standing issues, physical therapy may extend to 12 weeks or more.
Common Phases of Treatment
- Initial Phase (Weeks 1 – 2)
Focuses on reducing pain and inflammation with gentle exercises, stretching, and possibly manual therapy.
- Strengthening Phase (Weeks 3 – 6)
Builds core strength and stability to support the spine. You’ll begin more active exercises, targeting the abdominal, hip, and back muscles.
- Maintenance & Prevention Phase (Weeks 7+)
Focuses on posture correction, flexibility, and long-term injury prevention. Your therapist may reduce in-clinic sessions and emphasize home exercises.
Factors That Affect Treatment Length
- Type & Severity of Injury – A simple muscle strain may resolve quickly, while herniated discs or chronic conditions may take longer.
- Frequency of Visits – More frequent sessions may accelerate progress.
- Patient Compliance – Doing your home exercise program and following postural advice can significantly shorten recovery time.
- Age & Overall Health – Seniors or those with underlying conditions may need a longer plan.
- Lifestyle Factors – Poor posture, prolonged sitting, or physically demanding jobs can impact healing.
When Should You Stop Physical Therapy?
You & your therapist will decide when you’ve met your goals. Signs you may be ready to stop therapy include…
- Significantly reduced or eliminated pain
- Improved flexibility and range of motion
- Stronger core and back muscles
- Confidence in doing daily activities pain-free
- A consistent home exercise routine you can maintain independently
Even after therapy ends, continuing light exercise and maintaining good posture will help keep your back healthy.
