The following comes to us from faculty member Allison Ariail. Allison teaches several courses for the Institute, her next one being Rehabilitative Ultrasound Imaging in Baltimore, MD on June 12-14. There is still room, so sign up today!
Living in Colorado, I come across a lot of individuals who are avid runners, cyclists, or triathletes. Even with a higher level of fitness, these individuals will at times have back pain. What is going on in these physically fit, strong individuals? This is what Rostami et al. set out to determine in their recent study. Using ultrasound imaging, they measured the thickness of the transversus abdominis, internal oblique, external oblique, and the cross sectional area of the multifidus while laying down as well as while mounted on a bicycle. They also measured the back strength, endurance, and flexibility of off-road cyclists with and without back pain. Fourteen professional competitive off-road cyclists with low back pain were compared to 24 control. Results showed a significantly thinner transversus abdominis, and cross sectional area of the multifidus muscle in the cyclists with back pain. There was no significant difference found in flexibility or isometric back strength between the two groups. However the cyclists with low back pain demonstrated decreased endurance in back dynamometry with 50% of their maximum isometric back strength.
The results of this study are consistent with other studies that examined less athletic individuals; thinner transverseus abdominis, and smaller multifidus muscles. This further reinforces the training of the local stabilizing muscles. What does this training method consist of? Learning to isolate each of the local stabilizing muscles; the transversus abdominis, the multifidus, and the pelvic floor muscles. Once a patient is able to isolate a contraction, challenge the muscles by holding a contraction while breathing normally, or holding the contraction while performing motor tasks such as Sahrmann’s exercises. Progress the patient so they are able to perform contractions in weight bearing positions and co-contractions of the muscles. Finally, progress the patient to maintaining co-contractions during functional activities and exercise activities. This will improve stability of the back and pelvis as well as decrease the pain experienced by the patient.
Even patients with higher levels of activity and physical fitness can benefit from a program such as this one. I have used this treatment protocol using ultrasound imaging to confirm and train the local stabilizing muscles on individuals who are both active as well as with individuals not able to participate in as much physical activity. Each and every patient has made gains, even patients who already had a higher level of activity and sports participation such as cyclists, runners, and triathletes. It is rewarding to see all patients make gains and improvements!
