Resumen
Introduction: Musculoskeletal anatomical assessment by imaging in clinical examination of the foot is digital photography assessing surface morphology. Objectives: To validate the acquisition of photographic images of the foot, to calculate the longitudinal, angular and plantar arch index measurements of the above images using a podoscope and photogrammetry in healthy subjects and to categorize the normality of the measurements. Methods: This study was exploratory and was performed using a prototype camera around a podoscope and image analysis software. The photographic image was evaluated by longitudinal, angular and plantar index measurements. Results: The 30 healthy subjects evaluated had a mean age of 25.06 ± 11.95 years, females predominated with 53.3%. The mean total foot length, metatarsal width and instep height for the right side at 226 55 ± 36.49mm, 98.99 ± 22.71 mm, and 36.32 ± 4.07 mm respectively; and for the left side at 229.81 ± 42.25 mm, 104.49 ± 16.84mm and 36.31 ± 3.32mm respectively. The 1-2 ray intermetatarsal angle, 4-5 ray intermetatarsal angle and rearfoot angle for the right side were 14 ± 4º, 11 ± 3º and 2 ± 2º respectively; for the Left side 14 ± 3º, 9 ± 3º and 2 ± 2º respectively and the plantar index of the right and left arch were 0.23 ± 0.2 and 0.22 ± 0.1 respectively. Variability was only present in the forefoot at 20%. Conclusions: The photographic images of the foot were valid, the measurements were lower or similar to other studies. The variability of normality was only present in the forefoot.
