I had horrible problems with my L5/S1 lower back and found the PRO institute. I promised I would write a follow up review. I’m actually a little freaked out because I’m about 80-90% back to normal. I love doing spin, yoga, Pilates and I feel like I’m back without post workout pain. I’m still careful but I’m literally amazed that I rarely have pain.
Understanding Shoulder Impingement
Shoulder impingement occurs when the tendons of the rotator cuff and the subacromial bursa are compressed beneath the acromion bone, causing inflammation and pain. This common condition affects adults and athletes, often due to repetitive overhead motions, poor posture, or age-related changes.
Typical symptoms include:
- Pain when lifting or reaching overhead
- Shoulder weakness or stiffness
- Nighttime pain interfering with sleep
Research indicates that nearly 30% of adults experience shoulder impingement symptoms during their lifetime. Early intervention with regenerative treatments can prevent progression and restore function effectively.
Research Papers: Advancing Evidence-Based Treatment
Our practice integrates current evidence, such as:
- “Efficacy of Platelet-Rich Plasma in Rotator Cuff Tendinopathy,” Journal of Orthopedic Science, 2023
- “Clinical Applications of Stem Cells in Shoulder Tendon Repair,” Regenerative Medicine Journal, 2022
These studies support the safety and effectiveness of the biologic therapies offered at our Los Angeles center.

Regenerative Treatment Options for Shoulder Impingement
Our therapies harness your body’s natural healing power:
Platelet-Rich Plasma (PRP) Therapy
PRP is derived from your own blood and contains growth factors that stimulate tendon repair and reduce inflammation. Ultrasound guidance ensures precise injections into affected areas, leading to:
- Faster recovery times
- Significant pain relief
- Improved shoulder strength and function
Clinical studies report over 70% patient satisfaction with PRP for rotator cuff-related conditions.
Stem Cell Therapy
For chronic or severe cases, stem cell injections promote tissue regeneration and may improve long-term outcomes beyond traditional treatments.
Frequently Asked Questions (FAQ)
-
Typically, repetitive overhead activity, poor shoulder mechanics, or anatomical variations cause tendon compression beneath the acromion.
-
Diagnosis involves a detailed physical exam and imaging techniques such as ultrasound or MRI to confirm tendon inflammation or injury.
-
Most patients report only mild discomfort during the procedure, which is performed under local anesthesia and ultrasound guidance for precision.
-
Many patients experience noticeable pain reduction and improved mobility within 4 to 8 weeks after treatment, with continued improvement over several months.
-
Surgery is reserved for cases that do not respond to conservative or regenerative treatments. Many patients avoid surgery with early intervention.
-
Minimal downtime is typical. A personalized rehabilitation program supports gradual return to normal activities.
-
Regenerative treatments are often elective and may not be covered by insurance. Our office provides clear pricing and financing options.
