Randomized Controlled Trial Comparative Study
Knowledge transfer of spinal manipulation skills by student-teachers: a randomised controlled trial.
To assess the use of peer-assisted learning (PAL) of complex manipulative motor skills with respect to gender in medical students. ⋯ The peer-assisted learning system does not seem to be generally qualified to transfer such complex spatiotemporal demands as spinal manipulative procedures.

Comparative Study
The effect of standard and low-modulus cement augmentation on the stiffness, strength, and endplate pressure distribution in vertebroplasty.
Vertebroplasty restores stiffness and strength of fractured vertebral bodies, but alters their stress transfer. This unwanted effect may be reduced by using more compliant cements. However, systematic experimental comparison of structural properties between standard and low-modulus augmentation needs to be done. This study investigated how standard and low-modulus cement augmentation affects apparent stiffness, strength, and endplate pressure distribution of vertebral body sections. ⋯ Augmentation connecting both endplates significantly strengthened and stiffened vertebral body sections also with low-modulus cement. A trend of reduced pressure concentrations above/below the cement was observed with low-modulus cement.
