How Long Does Physical Therapy Last For Lower Back Pain?

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.
