Randomized Controlled Trial
Effect of mental processing on low back load while lifting an object.
Biomechanical study using a 3D motion analysis system conducted in a laboratory setting. ⋯ 2.

A prospective study. ⋯ The results of this study confirm biomechanical assumptions associated with the Zero-P spacer. Implantation of this new cage results in setting required biomechanical conditions in the treated segment that are comparable with those when the segment is treated with a dynamic plate. However, the potential of the mentioned implant to reduce the incidence of postoperative dysphagia was not proven on this sample of patients.

A case report. ⋯ Increased frequency and severity of respiratory tract infections, difficulty in expelling mucus and dyspnea are warning signs of compromised airways. Spirometry tests and image tests such as computed axial tomography and bronchoscopy are essential for diagnosis. Surgical approach may be the treatment of choice.
