Calm the Tendon
Manual therapy for the shoulder and upper back, activity modification, and laser therapy to reduce pain so loading can begin sooner.

Getting Started
Relief for Rotator Cuff and Biceps Tendonitis
Reaching overhead, sleeping on your side, lifting a bag into the car: shoulder tendonitis turns ordinary movements into a wince. At AR Physical Therapy we treat rotator cuff and biceps tendon pain with a plan that calms the tendon, rebuilds its capacity and fixes the mechanics that overloaded it.
Tendons heal through the right amount of load. We settle the pain first, then progressively strengthen the tendon and the muscles that control the shoulder blade, using deep tissue laser therapy where it helps you tolerate the work.
Whether your goal is throwing, swimming, work or a full night's sleep, the plan is built around it.

How We Treat Shoulder Tendonitis
Understanding Shoulder Tendonitis
Tendons need load,
not rest.
not rest.
The rotator cuff is a group of four tendons that hold the ball of your shoulder centered in its socket. When one of them, most often the supraspinatus, is asked to do more than it can handle, it becomes painful and thickened. The long head of the biceps tendon at the front of the shoulder follows the same pattern.
The word tendonitis suggests inflammation, but most persistent tendon pain is better described as tendinopathy: a tendon that has lost some of its structure from overload, under-recovery or years of poor mechanics. That matters, because a tendinopathy improves with graded loading rather than rest alone.
Overload
A sudden jump in lifting, training or overhead work
Under-Recovery
Repetitive overhead demands without time for the tendon to adapt
Mechanics
Rounded desk posture and shoulder blades that do not do their share

How We Treat It
Calm it, load it,
fix the cause.
fix the cause.
Every plan follows the same sequence and every step is matched to what your tendon can tolerate today.
/02
Load the Tendon
A progressive rotator cuff program, starting with isometrics for pain relief and building through resisted and overhead work as the tendon tolerates it.
/03
Control the Shoulder Blade
Scapular strengthening and retraining so the cuff is not doing the job of the larger muscles around it.
/04
Fix the Mechanics
Posture, thoracic mobility and, for overhead athletes, throwing or swimming mechanics assessed with DorsaVi motion sensors.
Why Choose Us
Reach Overhead Without Thinking About It
Deep Tissue Laser Therapy
Laser that reaches
the cuff.
the cuff.
The supraspinatus tendon sits two to three centimeters below the surface, beneath the point of the shoulder, which is beyond the reach of low-level lasers. The LightForce Class IV laser delivers near-infrared light to that depth, increasing circulation in a tendon with a poor blood supply of its own and reducing the pain that makes loading hard to tolerate.
A 2021 review of 17 randomized trials found that laser combined with exercise reduced tendon pain and improved function more than exercise with sham laser, while laser without exercise did not outperform other treatments. A 2025 study of rotator cuff patients receiving laser alongside exercise-based rehab reported pain dropping from 7 out of 10 to under 3 over six weeks, with better range of motion.
The lesson is the same in both: laser makes the loading program work better, and the loading program is what restores the tendon.
Recovery
What progress
looks like.
looks like.
Tendons change slowly, so expect steady progress rather than a quick fix. Pain typically eases within the first two to four weeks as loading and laser begin, and most people are back to overhead activity within six to twelve weeks.
Load Daily
Do the loading program exactly as prescribed. Complete rest weakens the tendon further.
Sleep Supported
A pillow under the arm takes the tendon off stretch if side-lying hurts.
Keep It Moving
Move the shoulder through pain-free ranges every day so it does not stiffen while it heals.
Why AR Physical Therapy

Questions
Common questions.
Should I rest my shoulder completely?
No. Complete rest weakens the tendon further. We guide you on what to avoid and what to keep doing.
Do I need an injection or surgery?
Most shoulder tendinopathy improves with a well-run loading program. We will tell you plainly if your exam suggests a tear or another problem that needs a physician's opinion.
How long is a laser session for the shoulder?
Four to eight minutes, delivered within your regular PT visit.
Can laser help after rotator cuff repair?
Laser is used after cuff repair to support healing and manage pain, on a schedule coordinated with your surgeon.
