Sitting and low back pain: the positive effect of rotary dynamic stimuli during prolonged sitting.
In this study the effect of dynamic stimuli on low back pain during prolonged sitting was investigated. The pain experience of two groups of 60 subjects with a specific low back pain was recorded. ⋯ Two different frequencies of rotation were applied in subgroups. The authors concluded that such stimuli, especially of the lower frequency, reduced pain in prolonged sitting.

Lumbar spine stability can be augmented with an abdominal belt and/or increased intra-abdominal pressure.
The increased intra-abdominal pressure (IAP) commonly observed when the spine is loaded during physical activities is hypothesized to increase lumbar spine stability. The mechanical stability of the lumbar spine is an important consideration in low back injury prevention and rehabilitation strategies. This study examined the effects of raised IAP and an abdominal belt on lumbar spine stability. ⋯ The belt had no effect on the activity of any of the muscles with the exception of the thoracic erector spinae in extension and the lumbar erector spinae in flexion, whose activities decreased. The results indicate that both wearing an abdominal belt and raised IAP can each independently, or in combination, increase lumbar spine stability. However, the benefits of the belt must be interpreted with caution in the context of the decreased activation of a few trunk extensor muscles.

The Modular Type SB Charite disc prosthesis has been developed as a device for artificial disc replacement (ADR) in patients with symptomatic discopathies. Here, we report on our first series of 50 (out of 350) patients, who had a satisfactory clinical result in 70% of cases (2 years' follow-up). Subgroup analysis revealed that patients with an isolated discopathy without previous spinal operations or other pathology at the same or other spinal level benefitted more from the surgery. ⋯ We conclude that in patients with severe isolated symptomatic discopathies that are resistant to conservative treatment, a mobile disc prosthesis is worth considering as a real alternative to a spondylodesis. However, accurate patient selection is imperative. With these criteria we were encouraged by our results to continue the implantation of this artificial disc.

Various conditions such as fracture, dislocation, tumor, or infection adversely affect the vertebral body and lead to instability. Restoration of a stable anterior column is essential for normal spinal biomechanics. Various biological and mechanical spacers have been used to reconstruct the anterior column after corpectomy. ⋯ For patients presenting with neurological symptoms (n = 4), the recovery was complete in three and partial in one. No patient was made neurologically worse, and there were no vascular injuries intra- or postoperatively. The study suggests that TSM-bone graft composite offers excellent biomechanical stability in the immediate postoperative period, permitting progressive maturation of the fusion mass.

It has been found that the pain patterns in pain drawings are related to the presence of herniated disc identified by myelography. The purpose of this study was to determine whether the pattern of pain in the drawings or the type of pain indicated (aching, burning, numbness, pins and needles, stabbing) was related to the presence of symptomatic disc pathology identified by CT/discography. In a subgroup of patients who underwent myelography, the relationship of the drawings to myelographic findings was also investigated. ⋯ Patients with discogenic pain used more symbols indicating burning pain and aching pain than did non-discogenic pain patients. Our results confirmed those reported earlier by Uden, who found a relationship between the pattern of pain in the drawings and myelographic findings. Pain drawings may be helpful in the diagnosis of symptomatic disc pathology.
