Pedabarography May Play a Role in Foot Plantar Scanning in Acromegaly.

Aims: Acromegaly is associated with symptoms in many organs, including the heart, colon, skin, bones, and many joints. Patients with long-term treatment or biochemical control still suffer from acromegaly arthropathy (AA). Primarily, the weight-bearing joints of the lower extremity are affected and at last deformation emerges. The aim of this study is to detect the changes in the feet with pedabarography in patients with acromegaly.

Materials and Methods: Nineteen patients with acromegaly (4 males and 15 females) and 13 healthy controls (1 male and 12 females) were included in the study ( p =0.31). There was no difference between acromegaly patients and controls in terms of gender, age, and BMI; median age and BMI were (54 (20-67) vs. 52 (30-58), p =0.85) and (32.5 (20.3-42.7) vs. 29.5 (22.4-38.6), p =0.93), respectively. Static plantar pressures of bilateral foot of all participants in the standing position were measured by pedabarography.

Results: In pedabarographic analysis, there were only significant difference in rearfoot surface right and rearfoot surface left ( p =0.04 and p =0.01), respectively. The mean of the right rearfoot surface (43.5 cm2 vs. 36.6 cm2 ) and the mean of the left rear foot surface were higher than the controls (47.4 cm2 vs. 40.2 cm2 ). Forefoot surface, forefoot load, forefoot weight ratio, rearfoot load, total foot surface, total load, total peak pressure, and total average pressure were higher in left foot in both groups, but there was no difference between the two groups.

Conclusion: In our study, there was a significant difference between acromegaly patients and healthy controls, only on the right rarefoot surface and the left rarefoot surface, and was higher on the left in both groups. These patients often experience changes in the hindfoot and heel, and foot surface area and pressure distribution may vary. Early diagnosis and proper treatment of the disease can prevent the development of complications and improve the quality of life. Foot scanning using pedabarography in the management of AA is a useful tool that can be used to manufacture customized orthopedic insoles and ergonomic shoe designs to prevent irreversible damage and reduce overload and lower extremity pain.
