Entering the Alignment Zone for Thoracic Outlet Syndrome (TOS)
When your arm feels heavy, strange, or fatigued whenever you raise it above your head—like doing your hair, reaching into a deep cabinet, or holding a steering wheel while driving down I-2—you need your collarbone, first rib, and shoulder blade brought into the alignment zone.
Many patients in Pharr, San Juan, and across the PSJA area assume their arm heaviness is just "poor posture" or a pulled shoulder muscle. They try sitting up straighter or buying posture straps online. But if the space between your neck, collarbone, and first rib (*the thoracic outlet*) is compressed, forcing a straight back compresses the nerves and blood vessels even further.
At South Texas Accident & Injury, getting your upper body into the true alignment zone requires a clinician who has mastered delicate rib and cervical mechanics. Dr. Paul Sta. Juana, DC developed his mastery of alignment zone techniques during intensive international volunteer mission trips. While other students were on break, Dr. Paul traveled abroad with a small collective of chiropractors, adjusting hundreds of patients daily in underserved areas using nothing but his hands.
Located just 3 minutes East down Highway 83 at 505 W Business Hwy 83 Ste 7 in Alamo, TX, our facility brings you straight into the alignment zone: combining mission-tested chiropractic mobilization with licensed physical therapy under one roof.
"When Your Arm Gets Heavy Overhead"
The nerves (brachial plexus) and blood vessels supplying your arm travel through three tight passageways: between your scalene neck muscles, beneath your collarbone (*clavicle*), and under your minor chest muscle. If a elevated first rib or dropped shoulder blade narrows any of these tunnels, the arm loses its normal signal and circulation.
"If your arm gets heavy when you raise it, that is not something to ignore. We see this with people who feel numbness when they drive, tingling at their desk, heaviness when doing their hair, or the need to keep shaking the arm out. Do not keep treating it like only bad posture if the arm still goes heavy, numb, or weak. The pathway needs a closer look."
Why Forcing "Good Posture" Fails TOS Pain
When you force your shoulders back to fix Thoracic Outlet Syndrome without unblocking restricted joint articulations, you create a mechanical trap:
- Clavicular Pinched Space: Pulling your shoulders back hard without mobilizing an elevated first rib clamps the collarbone directly onto the brachial plexus nerve bundle.
- Scalene Muscle Spasms: Over-stretching tight neck muscles causes them to contract harder in a protective reflex, further constricting the interscalene triangle.
- Scapular Winging: If your lower trapezius and serratus muscles aren't holding your shoulder blade upright, gravity pulls the whole shoulder girdle downward, stretching the nerves continuously.
The Open Window Method: Joint Unloading + Immediate Physical Therapy
At South Texas Accident & Injury, we bring you into the alignment zone for Thoracic Outlet Syndrome by utilizing The Open Window Method:
"Chiropractic mobilization of the cervical spine, first rib, and collarbone opens the compressed thoracic outlet space, creating an 'open window.' Performing physical therapy immediately afterward retrains your scapular stabilizers to maintain that open pathway under daily overhead loads."
CHIROPRACTIC UNLOADING → OPENS MOVEMENT WINDOW → IMMEDIATE PHYSICAL THERAPY STABILIZATION

Frequently Asked Questions
Where is your clinic located relative to Pharr and San Juan, TX?
Our facility is located at 505 W Business Hwy 83 Ste 7 in Alamo, TX 78516—a direct 3-minute drive East straight down Expressway 83 / Business 83 from Pharr and San Juan.
How do I know if my arm heaviness is Thoracic Outlet Syndrome or Carpal Tunnel?
Thoracic Outlet Syndrome typically affects the entire arm or hand when reaching overhead, driving, or holding objects, often causing heaviness, coldness, or whole-hand tingling. Carpal Tunnel Syndrome causes numbness strictly in the thumb, index, and middle fingers at the wrist. Our clinical team performs specific positional maneuvers (like Adson's and Roos tests) during your exam to confirm the diagnosis.
Why is physical therapy performed immediately after chiropractic first rib mobilization?
Timing is critical. Chiropractic mobilization unblocks the first rib and collarbone, opening the narrow thoracic outlet passageway. Performing physical therapy immediately afterward retrains your scapular stabilizing muscles to hold your shoulder girdle up, stopping the collarbone from crushing the nerves again.
