Back pain is keeping you from the runs, workouts, and life you love — and generic PT isn’t fixing it. At Dimensions Physical Therapy, every session is 60 minutes, 1-on-1 with Dr. Sarah O’Reilly, a Doctor of Physical Therapy who finds and treats the root cause of your pain. No techs. No guesswork. Just real results for active people in Cambridge who are ready to move freely again.
You’ve tried rest, you’ve tried stretching, maybe you’ve even tried another PT clinic — but the pain keeps coming back. When back pain goes untreated or undertreated, the consequences go beyond discomfort. It sidelines your training, disrupts your sleep, and chips away at the life you’ve built around staying active.
Every week with unresolved back pain is another week of lost progress — missed runs, skipped workouts, and fitness goals slipping further out of reach.
Cookie-cutter exercise sheets and rushed appointments at high-volume clinics treat your symptoms — not the source. The pain returns because the root cause never gets addressed.
Ignored back pain has a way of becoming chronic. What started as a manageable ache can evolve into a long-term limitation that affects every corner of your life.
Dimensions Physical Therapy isn’t a PT mill. We’re a one-on-one practice in Cambridge, MA where Dr. Sarah O’Reilly spends every minute of your 60-minute session focused entirely on you. Using a comprehensive biomechanical assessment, she identifies the true root cause of your back pain — then builds a personalized treatment plan that gets you back to doing what you love, stronger and more resilient than before. Active adults, runners, CrossFitters, and athletes across the Greater Boston area trust Dimensions PT because we treat you as a whole person, not just a diagnosis.
Your first session is a comprehensive biomechanical assessment. Dr. Sarah takes the time to understand your history, your goals, and what’s really driving your pain or limitation — not just the symptom on the surface.
You receive a fully individualized plan built around your sport, lifestyle, and recovery timeline. Expect hands-on treatment, targeted exercise programming, and advanced modalities — all in one dedicated session.
With consistent 1-on-1 care and ongoing programming adjustments, you’ll rebuild strength, move pain-free, and get back to running, training, and living without worrying when the pain will come back.
Back pain is rarely just a back problem. At Dimensions Physical Therapy in Cambridge, MA, we treat the full spectrum of musculoskeletal and performance-related conditions — identifying the interconnected movement patterns that contribute to your pain and dysfunction. Whether you’re searching for back pain relief near me or managing a recurring injury, we have the tools and expertise to help.

“There are no hidden costs, and every session is one-on-one with her full attention on helping you get better. Her diagnoses have been spot-on every time. She takes the time to explain what’s going on and how to fix it.”

Everything you need to know before booking your first back pain appointment at Dimensions PT.
Dimensions Physical Therapy is a self-pay practice. We do not bill insurance directly, which means no surprise bills, no claim denials, and no limits on the type or length of treatment you receive. Many patients find that the quality and efficiency of 1-on-1 care more than offsets the out-of-pocket cost. HSA and FSA cards are typically accepted — contact us to confirm.
Every session is 60 minutes, 1-on-1 with Dr. Sarah O’Reilly — from start to finish. There are no hand-offs to aides or assistants. Sessions typically include a movement assessment, hands-on treatment (such as manual therapy, dry needling, or cupping), and guided therapeutic exercise. You’ll also receive a personalized home exercise program through our web app.
Dry needling is a technique that uses thin needles to target tight muscle bands and trigger points contributing to your back pain. It is distinct from acupuncture and works by releasing muscular tension and promoting healing in the affected tissue. Dr. Sarah will determine during your assessment whether dry needling is appropriate for your condition and discuss it with you before beginning.
Every patient and every case is different. After your initial assessment, Dr. Sarah will outline a realistic treatment timeline based on the root cause of your back pain, your goals, and your activity level. Many active patients see significant improvement within a few weeks of consistent treatment.
Yes. In addition to in-person sessions at our Cambridge, MA clinic, we offer telehealth PT sessions and Online Programming & Coaching for patients in the Greater Boston area. Remote programming is also available for athletes who need professional coaching around an injury without interrupting their training schedule.
Absolutely. While we specialize in serving active adults and athletes, anyone experiencing back pain or musculoskeletal discomfort is welcome at Dimensions PT. Our whole-person approach is effective for desk workers managing postural pain, active parents, and anyone seeking long-term, root-cause solutions to their pain.
