Thoracic Outlet Syndrome: What the Research Shows

Curated & reviewed by Dr. Nikolay Chernukhin, D.C.

Bottom line: For thoracic outlet syndrome, non-surgical care such as chiropractic and manual therapy, exercise, and massage appears to reduce pain and improve movement for some people, but the evidence comes mostly from small, low-quality studies with no randomized trials, so the benefits are promising rather than proven.

Thoracic outlet syndrome happens when the nerves or blood vessels in the narrow space between your neck and shoulder get compressed, causing pain, numbness, or tingling in the arm and hand. Below is a plain-language look at what published research says about non-surgical care — chiropractic and manual therapy, exercise and rehab, and massage — for this condition. We have tried to be honest about where the evidence is encouraging and where it is still thin.

Chiropractic & manual therapy

Systematic review: The effectiveness of physical treatments on thoracic outlet syndrome in reducing clinical symptoms

Lo CN (Christopher), et al. · Hong Kong Physiotherapy Journal · 2011

This review of the research found that hands-on physical treatments may ease thoracic outlet syndrome pain, but the studies were low quality with no randomized trials, so the benefit is not firmly proven.

Conservative treatment of thoracic outlet syndrome. A review of the literature

Vanti C, et al. · Europa Medicophysica (Eura Medicophys) · 2007

This literature review found that conservative care like manual therapy, exercise, and posture work may help with pain and returning to activity, but with no randomized trials the authors could not say which approach works best.

Acute effects of manual therapy on respiratory parameters in thoracic outlet syndrome

Fırat T, et al. · Turkish Journal of Thoracic and Cardiovascular Surgery (Turk Gogus Kalp Damar Cerrahisi Derg) · 2019

In this small study of 10 patients with no comparison group, a single 30-minute manual therapy session lowered pain and boosted breathing-muscle strength, though the lack of a control group makes the results only suggestive.

Chiropractic care of a patient with thoracic outlet syndrome and arrhythmia

Shreeve MW, et al. · Journal of Chiropractic Medicine · 2011

This is a single-patient report where chiropractic neck adjustments were tied to relief of thoracic outlet symptoms, which shows one possible approach but cannot prove the treatment caused the improvement.

Exercise & rehab

Physical assessment and rehabilitation for neurogenic thoracic outlet syndrome (NTOS): A scoping review

O'Sullivan J, et al. · Hand Therapy · 2026

This review of rehab studies found that exercise (stretching, strengthening, and posture work) is the most common conservative treatment for nerve-related thoracic outlet syndrome, but concluded the overall evidence quality is still low.

Role of therapeutic exercises in neurogenic thoracic outlet syndrome

Hanif S et al. · Journal of Ayub Medical College Abbottabad (JAMC) · 2007

This study reported that a program of stretching, strengthening, and posture exercises significantly improved symptoms of nerve-related thoracic outlet syndrome, supporting exercise as a sensible first treatment to try.

Massage & soft tissue

Case report: the effects of massage therapy on a woman with thoracic outlet syndrome

Wakefield ML · International Journal of Therapeutic Massage & Bodywork · 2014

In this single-patient report, several weeks of massage therapy were linked to less pain, better neck movement, and improved sleep, but one case cannot prove massage works for everyone.

NTOS symptoms and mobility: a case study on neurogenic thoracic outlet syndrome involving massage therapy

Streit RS · Journal of Bodywork and Movement Therapies · 2014

In this single-patient study, eight massage sessions over about five weeks were tied to better shoulder movement and less pain and numbness, suggesting massage may help but not proving it on its own.

Frequently Asked Questions

Does chiropractic help thoracic outlet syndrome?

Chiropractic and other hands-on manual therapies may ease thoracic outlet syndrome pain and improve movement, and some patients in case reports did well. But the evidence is limited to small studies and single-patient reports with no randomized trials, so it is not proven to work for everyone.

What exercises help thoracic outlet syndrome?

Stretching, strengthening, and posture exercises are the most common first-line treatment, and studies suggest they can improve symptoms of nerve-related thoracic outlet syndrome. Exercise is a reasonable place to start, though the overall quality of the research is still low.

Can massage help thoracic outlet syndrome?

Massage and soft-tissue work have been linked to less pain, better movement, and improved sleep in published case reports. Those are single-patient results, so massage may help as part of a broader plan but has not been proven in larger trials.
