RESUMO
The Electrodynogram (EDG) system of foot-fall measurement has been in clinical use for more than 15 years. Recently the EDG was acquired by Tekscan, which manufactures the F-Scan system of foot-pressure analysis. The new F-Scan system with EDG module retains all of the benefits of the F-Scan system while incorporating the valuable temporal and pressure data comparisons offered by the EDG. This merging of technologies has resulted in a system that is more suitable for application in the pediatric patient than either system alone.

An overview of the normal and abnormal functional equilibrium of the lower extremity has been presented. The biomechanical and pathomechanical implications of activity and inactivity on this system have been discussed. Special emphasis has been placed on the effects of musculoskeletal imbalances on foot function. Evaluation and management guidelines for the restoration and rehabilitation of lower extremity functional equilibrium have been outlined. Familiarization with these concepts and techniques will enable the astute practitioner to prevent disruptions of extremity functional equilibrium and allow the individual to lead a more healthy, active lifestyle.

An overview of the clinical entity referred to as developmental flatfoot has been discussed. Specific reference has been made to its occurrence, etiology, identification, pathomechanics, clinical significance, and management rationale. This often overlooked, inconspicuous condition is the most common musculoskeletal abnormality affecting the foot of the child under 6 years of age. Recognition of the fact that the developmental flatfoot is the logical precursor of foot dysfunction, deformity, and resultant disability later in life will allow the practitioner to design a management program for today that will meet the foot health needs of tomorrow.

Tritium and argon radioactivities, attributable to galactic and solar cosmic-ray interactions, were measured in lunar soil and in three lunar rocks. The tritium in the soil, 325 +/- 17 disintegrations per minute per kilogram, is slightly higher than that in the rocks, 212 to 250 dpm/kg. For two rocks, the tritium was combined with the helium-3 in order to calculate exposure ages of 375 +/- 40 and 205 +/- 25 million years. The argon-37 radioactivities, 21.0 to 27.2 dpm/kg, and the argon-39 radioactivities, 12.1 to 16.4 dpm/kg, are slightly higher than those in stony meteorites. Higher exposure ages were obtained from the argon isotopes than from tritium and helium-3. On the basis of the known galactic cosmic-ray flux and the known cross section, at least half of the observed radioactivities are produced by solar cosmic rays.
