Design and Validation of a Device Attached to a Conventional Bicycle to Measure the Three-Dimensional Forces Applied to a Pedal.

Knowledge of the forces applied to the pedals during cycling is of great importance both from the point of view of improving sporting performance and medical analysis of injuries. The most common equipment for measuring pedal forces is usually limited to the study of forces in the sagittal plane. Equipment that measures three-dimensional forces tends to be bulky and to be incorporated into bicycles that are modified to accommodate it, which can cause the measurements taken to differ from those obtained in real pedalling conditions.

[Metabolic changes in brain cortex related with the strabismus treatment. Preliminary results with SPECT].

Objective: Our aim was to demonstrate metabolic changes occurring in brain cortex during strabismus treatment.

Material And Methods: Single photon emission computed tomography (SPECT) of brain was made in patient with strabismus. The study only included congenital esotropia and excluded patients with other anomalies.
