Randomized Controlled TrialHow effective is a modified exercise program on its own or with back school in chronic low back pain? A randomized-controlled clinical trial.
The aim of this trial is to search effectiveness of specifically adapted exercise programs on its own and with low back school on pain, disability, trunk and quadriceps muscle strength, walking performance, spinal mobility, quality of life (QOL), and depression in the patients with chronic low back pain (CLBP). ⋯ Diagnostic study Level-I-I (prospective study).

Low back pain risk factors associated with persistence, recurrence and delayed presentation.
There is little knowledge in the literature on the role of time-related variables for the prognosis of acute and subacute low back pain (LBP). ⋯ Patients with current LBP waiting longer until seeking help in primary care have a more disadvantageous profile of occupational and psychological risk factors and lower resource levels. A similar but less pronounced pattern occurred in those with subacute LBP compared to those with acute LBP. Consideration of time characteristics of LBP may help to better understand LBP.

Validation of the Persian version of the fear avoidance belief questionnaire in patients with low back pain.
Fear of pain or re-injury and avoidance attitudes have a great impact on maintenance of chronic low back pain (CLBP) and disability. Fear-Avoidance Beliefs Questionnaire (FABQ) is developed to assess these psychosocial factors. The aim of this study was to provide a translated and validated version of the FABQ for Persian speaking population. ⋯ The provided Persian version of FABQ is a reliable and valid measurement and further research into its use as a diagnostic and prognostic tool is warranted. Development of this questionnaire will be useful for comparability between Persian and English language studies and facilitates an international collaboration in this field.

Clinical TrialInfluences of posterior-located center of gravity on lumbar extension strength, balance, and lumbar lordosis in chronic low back pain.
In patients with chronic low back pain, the center of gravity (COG) is abnormally located posterior to the center in most cases. ⋯ These findings suggest that chronic LBP patients with P-COG have some disadvantages to establish lumbar extension strength and static and dynamic balance, which require specific efforts to maintain a neutral position and to control posture.

Normal postural responses preceding shoulder flexion: co-activation or asymmetric activation of transverse abdominis?
It is suggested that activation of the transverse abdominis muscle has a stabilizing effect on the lumbar spine by raising intra-abdominal pressure without added disc compression. However, its feedforward activity has remained a controversial issue. In addition, research regarding bilateral activation of trunk muscles during a unilateral arm movement is limited. The aim of this study was to evaluate bilateral anticipatory activity of trunk muscles during unilateral arm flexion. ⋯ Healthy subjects showed no bilateral anticipatory co-activation of TA/IO in unilateral arm elevation. Further investigations are required to delineate normal muscle activation pattern in healthy subjects prior to prescribing bilateral activation training of transverse abdominis for subjects with chronic low back pain.
