Comparative Study Clinical Trial
Clinical and radiological outcomes of unilateral versus bilateral instrumentation in two-level degenerative lumbar diseases.
To compare the clinical and radiological outcomes of unilateral versus bilateral instrumented in two-level degenerative lumbar diseases after minimally invasive transforaminal lumbar interbody fusion (MITLIF). ⋯ Unilateral instrumentation after two-level MITLIF provided similar clinical and radiological outcomes to bilateral fixation in two-level degenerative lumbar diseases. Compared with bilateral fixation, unilateral fixation shortens operation time, reduces intra-operative blood loss and X-ray exposure time, and saves medical expenses with similar postoperative hospital stay and complication rate.

Trunk Dynamics Are Impaired in Ballet Dancers with Back Pain but Improve with Imagery.
Trunk control is essential in ballet and may be compromised in dancers with a history of low back pain (LBP) by associated changes in motor control. This study aimed to compare trunk mechanical properties between professional ballet dancers with and without a history of LBP. As a secondary aim, we assessed whether asking dancers to use motor imagery to respond in a "fluid" manner could change the mechanical properties of the trunk and whether this was possible for both groups. ⋯ Although dancers with a history of LBP have less trunk damping than those without LBP, they have the capacity to modulate the trunk's mechanical properties to match that of pain-free dancers by increasing damping with motor imagery. These observations have potential relevance for LBP recurrence and rehabilitation.
