Inguinal Ligament Pain: Causes, Symptoms, Treatment
What is Inguinal Ligament and What is its Function?
The Inguinal Ligament is a constricted band of thick fibrous connective tissues which are present in the pelvic region of the body. These tissues arise from the external oblique and course through across the groin and attaches to the front part of the iliac spine. The inguinal ligament forms the floor of the inguinal canal and provides support to the passage of structures through the canal.
The inguinal ligament supports the muscles which course inferiorly to the fibers of the ligament, including the iliopsoas muscles. It also supports the femoral vein, artery, and nerve along with other blood vessels and nerves of the lower extremities as they course through the pelvic area. This support is important to maintain the flexibility of the hip and supply nutrients and blood supply to the lower extremities.

The Inguinal Ligament helps in preventing the intestines from projecting out from the groin. It also supports the external oblique muscles in the abdomen. Inguinal Ligament Pain is normally seen in athletes who run and sprint a lot and put these ligaments at risk of straining and tearing. A person suffering from Inguinal Ligament Sprain will experience unusual popping feelings in the pelvic region proceeded by severe pain. There will be palpable tenderness in the groin and inner thigh. The patient will also find it difficult to raise and lift the knee or bring the legs close together.

Physical Therapy for Inguinal Ligament Pain
Physical therapy is an important aspect for treating Inguinal Ligament Sprain. This is done in three levels.
Level 1 Physical Therapy for Inguinal Ligament Pain: In this regimen, light exercise like using a stationary bicycle with seat as low as possible and resistance set extremely low is recommended. This should be done as tolerated. Static groin stretches should be performed at least five times daily with each stretch being held for about 30 seconds.
Level 2 Physical Therapy for Inguinal Ligament Pain: Static groin stretches should be started and a strengthening program should be undertaken. Examples of groin strengthening exercises are straight leg raises in which you bring your leg toward the midline of the body and abduction where you pull your leg away from the midline of the body. Hip flexion, hip internal and external rotation can also be useful. These exercises need to be performed every alternate day.
Level 3 Physical Therapy for Inguinal Ligament Pain: This level of therapy starts approximately a week after the injury causing inguinal ligament pain. The exercises mentioned before need to be continued and may be progressed with more reps. Functional activities may begin as tolerated. When all the strength in the groin has returned and there is no pain with performing exercises then a gradual return to activity may be tried after Inguinal Ligament Sprain.
