Hip flexors and runners
the misunderstood muscles!

Hip flexors and runners

The hip flexors are often overlooked and not thought of as an important muscle to exercise for the improvement of strength. Many runners that have suffered from lower limb injuries had low gluteal activation. We believe that training of the glutes is a great way to improve efficiency and even speed and running performance. When there is tightness in the glutes, this hip flexor tightness may lessen gluteal activation.

Even though hip flexor tightness doesn’t always mean strength, this with activation are important for pelvic stability, hip stability, and for overall running. We see injured runners who have difficulty getting their hip flexion with other hip muscles really activated.

In a study In 2005, it was found that injured runners had significantly weaker hip flexor as well as muscle groups on the side that was injured. This was compared to a group of non-injured runners where leg dominance did not influence the injured leg. This study showed that by improving hip flexor strengths reduced PFP. We believe that this study and others show that hip flexor strength should be a part of assessments for runners who wish reach peak performance and prevent future injuries.

Diagnosis

app

A clinical exam and diagnostic ultrasound imaging can help your therapist pinpoint the exact location and cause of your hip and groin pain.

Ultrasound enables you and your therapist to view the hip and groin region in real time, while in motion. In addition to ultrasound, video gait analysis can help us identify faulty movement mechanics that contribute to hip and groin pain. Once the exact cause is determined, an effective treatment plan can be initiated.

Hip dysfunction and pain can be a complex issue due to interactions of the trunk, pelvis, low back, groin and hip joint. Physical therapy and rehabilitation that is based only on subjective clinical analysis often addresses the symptoms without resolving the underlying cause.

At NYDNRehab, our groundbreaking motion analysis technology and high resolution diagnostic ultrasonography have enabled us to develop a battery of tests that perfectly reveal the dynamic functional pathology of the hip joint and pelvis. Our tests are evidence-based protocols that are considered to be the gold standard in the world of research.

Our testing protocol includes:

1

Combined lumbopelvic hip stability test using DLEST methodology with C.A.R.E.N., our computer assisted rehab environment

2

Hip joint stability test using DLEST methodology with C.A.R.E.N.

3

3D star excursion banner test (SEBT) for assessing the involvement of the hip joint and muscles in postural stability

4

3D gait or running analysis

5

3D kinematic joint angle analysis during a squat, lunge, drop jump and pelvis on hip rotation

6

Rehabilitative ultrasonography for viewing intrinsic hip stabilizing muscle activation patterns

We also perform neuromotor testing with DD Robotech for:

  • Proprioception
  • Tracking ability
  • Force sense
  • Critical power
  • Reactive power
  • Flexibility

SEMG

Surface electromyography (SEMG) may be added to any of the above tests when needed.

Based on our experience and evidence-based information, we believe that physical therapy and rehabilitation should be based on objective quantifiable data.

In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
