Sleep deprivation is common in fibromyalgia patients, as the pain of the muscles during sleep will oftentimes cause the person to wake, never allowing them to fully reach the deep sleep level that is critical for an enjoyable life. Although testing can be rather subjective, there are several tests that can help point to an accurate diagnosis. The most important test consists of the 18 designated points along the upper and lower back and gluteal regions that will be more tender upon palpation. The amount of pressure needed at each of these points is approximately 10kg of pressure. This is the amount of pressure needed to change color of the thumbnail when pressing the thumb down on a hard surface.
Testing can extend beyond the criteria needed to establish a diagnosis.
A biomechanical exam is important, as balance and normal muscle function can only help those involved. Leg length measurements are important. Normal range of motion in the joints of the pelvis and spine are also important. Standing x-rays should be done of the low back and neck to determine disc heights, pelvic symmetry, gravity line, lordotic curves and the pelvic angle. Contrary to popular belief, all massage may not be beneficial to fibromyalgia patients.
