Head forward of optimal alignment collarbone, the head is too far forward for optimal alignment and may be contributing to their lower back problems (Chek 2001; Price 2018). 2 Lower back overarches Figure 1: Excessive curve in the lower back as a result of a forward head position Evaluating the position of the head The following assessment can help you evaluate whether a client’s head position may be contributing to their lower back soreness. Ask the client to sit on a gym ball or on the edge of a chair with the feet and head facing forward. Stand to one side of the client and locate the part of their cheekbone that protrudes outward the most, just below the eye. Place one of your index fingers on this part of the client’s cheekbone and your other index finger directly below it on the client’s collarbone. With your index fingers positioned in this way, stand directly over your fingers and look down to assess the position of your index fingers in relation to each other (see Figure 2). Ideally, they should be vertically aligned, that is, with the tip of one finger directly below the tip of the other (Chek 2001; Price and Bratcher 2010). If the end of the index finger on the client’s cheekbone is forward of the one on their Overpronation Overpronation, or collapsing of the feet and ankles, can cause musculoskeletal imbalances and myofascial restrictions to the structures of the lower back (Price 2018). Overpronation causes the feet and ankles to roll toward the midline of the body which, in turn, rotates the lower legs, knees and upper legs inward. This change in the position of the legs causes the hip sockets to shift backward, the pelvis to drop down and forward, and the lower back to overarch (see Figure 3) (Price and Bratcher 2010). Over time, this can cause excessive stress and strain to structures of the lower back and be a major underlying cause of pain and dysfunction in this area of the body. Evaluating for overpronation The following assessment can help you evaluate whether overpronation may be contributing to a client’s lower back pain. Ask the client to stand in bare feet facing you in their normal standing position. Now take a look at their feet, ankles and toes for visual indications of habitual overpronation. Since overpronation results in excessive pressure being transferred over the inside of the foot and ankle, the following issues may be present (see Figure 4): • inflammation and/or swelling at the ankle • inflammation of the first joint of the big toe (i.e. bunions) • calluses on the skin of the big toe • a big toe that has shifted toward the lesser toes (i.e. hallux valgus) • lesser toes that are scrunched up and/or appear bent and crooked. Overpronation also rotates the knee toward the midline of the body. To compensate for this position of the knee, a person will unconsciously turn their foot/feet noticeably outward to help externally rotate the lower leg and align the kneecap forward again. Therefore, a person who overpronates will typically have an abducted foot position (see Figure 4).
