Symptom behavior
We map the location, timing, position, and recovery of numbness, heaviness, pain, or fatigue.

Thoracic Outlet Syndrome
ARM SYMPTOMS NEED A CAREFUL SCREEN
Evaluation and rehabilitation for position-related arm heaviness, numbness, tingling, fatigue, and suspected neurogenic thoracic outlet syndrome.

TOS IS NOT ONE SINGLE PRESENTATION.
Thoracic outlet syndrome describes symptoms linked to compression of nerves or blood vessels as they pass between the neck, collarbone, first rib, and upper chest. Neurogenic, venous, and arterial presentations require different medical decisions.
Physical therapy may be part of care for neurogenic symptoms, especially when position, movement, strength, and workload affect the arm. Vascular symptoms need medical assessment and should not be treated like a routine shoulder problem.
Common Presentations
SYMPTOMS CAN CHANGE WITH ARM POSITION.
No single symptom confirms TOS. These patterns are reasons to get assessed rather than self-diagnose.
- Arm heaviness or early fatigue with the arm overhead
- Numbness or tingling into the arm or hand
- Symptoms that change with shoulder or neck position
- Loss of grip or arm endurance during repeated activity
What We Assess
SEPARATE WHAT LOOKS SIMILAR.
Neck, shoulder, nerve, and vascular problems can overlap. The evaluation should narrow the field and identify anything that needs medical testing.
Neck and nerve screen
The neck and peripheral nerves are checked because several conditions can mimic one another.
Shoulder and trunk capacity
Motion, strength, breathing mechanics, and repeated overhead work may affect the presentation.
Medical coordination
Vascular signs, progressive weakness, muscle loss, or an unclear presentation can require physician or specialist review.
The Rehab Process
BUILD ENOUGH CAPACITY FOR THE THING YOU WANT TO DO.
01
REDUCE THE PROVOKING DOSE
Change the positions, volume, or overhead exposure that repeatedly reproduces symptoms.
02
RESTORE OPTIONS
Work on motion, strength, and positions the arm can use without escalating symptoms.
03
REBUILD OVERHEAD CAPACITY
Progress repeated work, lifting, throwing, or sport demands while monitoring the full symptom response.
Swelling or color change needs prompt attention.
Sudden arm swelling, blue or pale color, unusual coldness, chest pain, shortness of breath, or a weak pulse can signal a vascular problem. Seek urgent medical evaluation instead of waiting for a routine physical therapy visit.
Common Questions
BEFORE YOU START
Is thoracic outlet syndrome the same as dead arm?
No. “Dead arm” is a broad description used by throwers for heaviness, weakness, or loss of arm speed. TOS is one possible cause among several and needs its own evaluation.
Can physical therapy help TOS?
Physical therapy may help some neurogenic presentations. The plan depends on the symptom pattern, exam, response to movement and loading, and whether medical testing is needed.
Do I need imaging?
Some people do. Imaging and vascular or nerve testing are medical decisions that depend on the suspected type of TOS and the exam findings.
