Visual accommodation system and its relationship with baropodometric parameters. Cross-association pilot study
Objective: to determine the relationship between accommodative visual dysfunctions and baropodometric values obtained through a pressure platform. Material and method: a descriptive and cross-sectional study between opometric and baropodometric variables measured through high repeatability methodology was carried out. Optometric variables were accommodative amplitude, relative accommodation, accommodative response and accommodative facility. Baropodometric variables were plantar surface, load and foot pressure, podalic angle and Fick angle. Thirty-four subjects (20 women and 14 men) with a mean age of 26 ± 6 (18-39) years were included and were classified into two groups according to the accommodative state: accommodative excess (AE) and accommodative insufficiency (AI). Results: our results showed that in both groups there is a greater percentage of load and maximum and average pressures in the left foot than in the right foot and greater surface area in both feet in the forefoot with respect to the hindfoot, but such differences were greater in the group of AE. On the other hand, the AE showed a higher percentage of forefoot load than in the hindfoot, with the opposite happening in the subjects with AI. Conclusions: the results show signs of a possible relationship between the visual dysfunctions of the accommodative system and some baropodrometric parameters. In both groups (AE and AI) there could be a postural alteration, being greater in the AE. More research is needed to identify the meaning of this relationship.
