Trigger Point Injection & Prolotherapy for shoulder joint pain


Ligament injuries are among the most common musculoskeletal injuries seen in clinical practice and ligaments are the most frequently injured structures in a joint. Ligaments play an important role in balancing joint mobility and joint stability. Disruption of joint ligaments severely impairs joint function.

Ligament and tendons are made of collagen. When the ligaments and tendons are injured, the body produces collagen to heal them. The problem with ligaments and tendons is that the body offers them a poor blood supply and, because of it, a poor chance to completely heal.

In non-injured ligaments or tendons, collagen fibers are flexible and have some elasticity. Elastic as they are, they are not supposed to stretch very far. Injuries occur when we stretch these fibers beyond their designed lengths. Injuries also occur when wear and tear through repetitive motion fray and tear at these fibers.

Injured, loose, or stretched out ligaments are often referred to as ligament relaxation, or Ligament laxity. This is what produces the pain and discomfort, especially with movement. Because of the laxity, the joint may move beyond its normal range of motion.


Proliferative therapy, or prolotherapy, is a treatment for damaged connective tissues involving the injection of a solution (proliferant) which causes local cell death and triggers the body's wound healing cascade.

Prolotherapy is a cutting-edge form of regenerative medicine that is leading the way in helping to treat both acute and chronic injuries, as well as difficult-to-resolve joint pain. You can benefit from prolotherapy if you have arthritis, a torn ligament, tendonitis, a bulging disc, or pain in any susceptible area such as your neck, lower back, knee or shoulder.

The goal of prolotherapy is to stimulate collagen formation and deposition through an inflammatory response. By doing so,tendons and ligaments are strengthened and joint stability is enhanced


In December 7, 2017 a 20-year-old young Asian male, tall and slender body type with frequent badminton playing, presented with 3 week history of Anterolateral shoulder joint pain which aggravated by extension and internal rotation of the shoulder joint (badminton smashing). In the shoulder orthopedic test, patient has positive sighs mostly in his Supra & Infraspinatus and Teress major muscle. Trigger point injection and prolotherapy has performed same day.

Results • 3 weeks later from the first treatment of prolotherapy, the patient reported a 90% reduction (slight discomfort when overly uses the area) in pain and full restoration of normal activity.
