PurposeTo determine both static and dynamic plantar data of acromegalic subjects while barefoot.MethodsSeventy acromegalic patients and 48 age-, sex-, weight- and height-matched healthy controls were included. Plantar variables were measured using the footscan gait system. The data included the width and length of each foot, relative force distribution in each quadrant, mean force applied to each foot and maximum pressure while walking. Maximum pressure data were obtained from ten parts of the foot. Injury risk assessments of five different regions were performed. To analyze balance, center of pressure (CoP) measurements were performed. The patients with acromegaly were compared with the controls. Furthermore, a comparison of patients with active and controlled acromegaly was performed.ResultsThe foot was wider in acromegalic patients. The mean force on each foot was higher in cases of acromegaly (acromegaly: 1027180N, control: 908 +/- 180N, p=0.001). In the acromegalic individuals, the maximum pressure in the midfoot was higher, while the medial heel maximum pressure was lower (midfoot maximum pressure acromegaly: 11.3 +/- 3.5N/cm(2), control: 8.9 +/- 3.7N/cm(2), p=<0.001). Injury risk was similar. CoP measurements elicited intact balance. In terms of static and dynamic plantar data, there was no difference between patients with active and controlled acromegaly.Conclusions This is the first study to demonstrate that compared with healthy controls, patients with acromegaly experience great force on their feet while standing and high pressure in the midfoot during walking. Podiatric evaluation, custom molded orthotics and individualized rehabilitation programs for acromegalic patients may provide better force and pressure distribution throughout the foot and improve gait and skeletal symptoms.
