Background summary
Sports physicians and sports physical therapists are regularly confronted with
complaints due to overuse. In this study, focus lies on athletes suffering
overuse complaints in the groin region. A big part of athletes experiences pain
when performing isometric hip adduction. Research has shown that wearing a
pelvic belt can reduce pain and increase force in a large proportion of these
athletes (Mens et al., 2006). The m. transversus abdominus (TrA) represents an
internal pelvic belt. Cowan et al. (2004) found a dysfunction of TrA in
athletes with longstanding groin pain using electromyography (EMG). It is
thought that proper recruitment of TrA is very important. Palpation of this
muscle's function is not possible since it is the deepest abdominal muscle.
Therefore, training of TrA is very difficult since controlling can not be done
visually nor by palpation. In physical therapy practice, ultrasound echography
is used a biofeedback tool. It is questioned if abnormalities in muscle
recruitment can also be visualized by ultrasound echography, so physical
therapists are aware of "normal" and "abnormal" muscle recruitment.
Study objective
The purpose of the present study is to compare the recruitment of the
transversus abdominis (and internal oblique) measured with ultrasound imaging
between athletes with and without long lasting groin injuries. In this study it
is hypothesized that ultrasonography is a valid method to detect changes in
activity of TrA in athletes with long-lasting groin pain, and can be used as a
biofeedback instrument in these athletes.
Study design
A crossectional study design is applied. Based on earlier studies we will
include 15 injured athletes, and 15 controls

Inclusion criteria
Healthy controls are included if they participate in sports, aged between 18-55, have not suffered athletes back or groin injury during the previous year
Patients are recruited if they are aged between 18-55 years; restricted in sports participation during a period of at least 4 weeks as a result of groin injury; pain at maximum isometric hip adduction.
Exclusion criteria
Patients are excluded if the pain started after a high-impact collision or foul; symptoms are the result of fracture of the pelvis or hip, osteoarthritis of the hip, rupture of the labrum of the hip, inguinal or femoral hernia, radicular syndrome, nerve entrapment, bursitis, malignant diseases, vascular pathologies, prostatitis, urinary tract pathology; anatomical abnormalities; other injuries preventing the patient to participate in the study; obvious psycho-pathology or unable to fill in forms; systemic diseases. Women are also excluded if they have a history of pregnancy.
