Regarding to high prevalence of low back pain (LBP) in athletes and its effect on their athletic function, an accurate evaluation before planning the rehabilitation program seems necessary in athletes with LBP. It should be considered that human movements are like as a kinetic chain. It means that any problems in every parts of this chain can cause dysfunction in the other parts of the chain. Not taking attention to the relationships between different parts of this chain may result in suboptimal rehabilitation. Therefore, focusing treatment on the entire parts of the kinetic chain besides the injured part, may prevent recurrenceof the dysfunction. Since in the kinetic chain hip muscles act as a link between lower extremities and trunk, the purpose of the present study was to evaluate and compare muscles strength of hip joint in female athletes with and without non-specific chronic LBP. Fifteen healthy female athletes and 15 female athletes with non-specific chronic LBP participated in this study. Their age was between 18-30 years. Hip extension, abduction and external rotation strength in all participants were measured. A hand-held dynamometer (HHD) was used to measure muscle strength. Since fixing HHD by examiner’s hand is fraught with error, it is fixed by a stable frame. The maximum strength value of hip extension and abduction in female athletes with LBP were significantly lower than these measures in healthy group (P < 0.05). No significant differences were seen in the maximum value of hip external rotation strength between two groups (P > 0.05). The results of the present study show that hip extension and abduction strength in female athletes with LBP were lower than these measures in healthy group. Therefore, hip strength measurements besides the examination of the spinal column seem to be necessary in evaluation and rehabilitation of the patients with LBP.

Comparison of global and local abdominal muscles thickness in chronic non- specific low back pain patients with healthy controls in position of hook-lying over variant stability surface utilizing diagnostic ultrasonography Methods and Materials: 20 chronic non-specific low back pain male patients compared with a convenient sample of age and gender matched healthy controls in a semi-experimental study. Thickness of abdominal muscles was measured in end of inspiration and expiration phases by B-mode linear ultrasound transducer in three different hook-lying positions over: 1- stable surface، 2- foam roller under spine and finally 3- foam roller under spine and one foot. Data were analyzed utilizing SPSS. In healthy controls internal oblique and transverse abdomens muscles in expiration phase revealed significant differences between three positions. P< 0. 001 In patients internal oblique and transverse abdomens muscles only revealed significant differences between position one and two. P< 0. 005 In low back pain subjects internal oblique and transverse abdomens muscles were unable to activate in more difficult position over unstable surface due to chronic pain process such as functional deficiency and decrease number of muscle spindle and muscle fiber atrophy.
