Clinical, Morphological and Functional Success Predictors Following Lumbar Spinal Surgery in Patients...

Low Back Pain

The long term goal of this project is dual fold. First, the investigators wish to derive, validate and then test the impact of a clinical prediction rule to determine which patients who suffer from CLBP with degenerative changes of the lumbar spine and referred pain to the legs are likely to require surgery and have successful outcomes in the long term. Second, the investigators would like to establish robust methodology and statistical analysis guidelines for creating clinical prediction rules in physical therapy research. This observational cohort project is a first step towards those goals. Here the investigators specifically aim to identify personal, behavioral, psychological, morphological, and physical factors that can predict the need for surgery as well as level of participation restriction in patients who suffer from CLBP with degenerative conditions of the lumbar spine and referred pain to the legs. The investigators will also explore which parameters can predict success after 1 month, 6 and 12 months in patients who underwent decompression/fusion surgery.

The Influence of Different Factors on Workers' Disability Due to Low Back Pain

Low Back Pain

The purpose of this study is to determine, in Spanish workers, the influence of different factors (personal, psychological, work related and clinical) on the risk of being on sick leave during the 18 months after baseline assessment, and on the duration of that sick leave.

Correlation Between Electromyography and Thickness Change of the Trunk Muscles in Subjects With...

Low Back Pain

Transversus abdominis (TrA) and lumbar multifidus (LM) muscle have been proposed to play key role in stability of the lumbosacral spine. The muscles' functional and/or structural deficits have been linked to the low back pain (LBP) syndrome. Evaluation of the transversus abdominis and lumbar multifidus muscles' function in clinical practice is scarce and not well defined due to number of reasons. Surface electromyography of TrA and LM muscles, as a method of examining muscles function, is not involved in clinical routine. Rehabilitative Ultrasound Imaging (RUSI) of the TrA and LM, apart from providing information about their morphology, could be helpful in assessing their function. Since concentric muscle contraction results in the shortening and thickening of the muscle, evaluation of the potential association between muscle's morphometry, assessed by the ultrasound, and electromyography, may be of potential clinical interest. However, this potential relationship is context-dependant. Our aim was to establish the difference in the thickness change of the TrA and LM muscle during activation in subjects with and without low back pain, and to establish the possible correlation between electromyography and the thickness change of these muscles assessed by ultrasound in both groups of subjects.

The Sacroiliac Joint With SIJ Nerve Entrapments and Chronic Low Back Pain

Chronic Low Back Pain

The overall goal of this study is to characterize the SIJ form, function, nerve entrapments, lumbo-pelvic configuration and their possible relationships with nonspecific chronic LBP in females and males. Specific aims: 1.To investigate the relationship between SIJ bridging and NSCLBP in females and males. 2. To investigate the prevalence and characterization of nerve entrapment of the lumbar sacral plexus around the SIJ in females and males. 3. To investigate the correlation between the lumbar sacral plexus nerve entrapments around the SIJ and NSCLBP in females and males. 4. To investigate the relationship between the lumbar sacral plexus nerve entrapments around the SIJ and lumbo-pelvic morphology in females and males. 5. To characterize the location and severity of articular degenerative changes in the SIJ and its relationship with lumbo-pelvic morphology in females and males. 6. To investigate the relationship between articular degenerative changes in the SIJ and LBP in females and males.

Back Pain and Male Sexual Disfunction

MarriageLife Event

Back pain is a common hormonal disorder in men that may affect the phases of male sexual function. The investigators investigated sexual function in male patients with back pain. A total of 54 men with back pain and 27 age matched voluntary healthy men who served as the as control group were evaluated with a detailed medical and sexual history, including a international erectile function index (IEFI) questionnaire and the Beck Depression Inventory. Serum prolactin, dehydroepiandrosterone sulfate, free testosterone, androstenedione, 17alpha-hydroxyprogesterone, estradiol, free thyroxin and thyrotropin were measured. These variables were compared statistically between the 2 groups.
