A comparative physiological and biomechanical study of 19 patients with phosphate diabetes (PD) and 44 patients with the lower limb varus deformities without PD has been performed. The retardation of body longitudinal growth, the decrease in limb muscle contractility, locomotion velocity- and force-related characteristics, capacity for work was revealed in patients with PD. The moderate decrease in the muscle strength of the leg deformed, the weakening of foot balancing function and the decrease of loading foot parts in walking was observed in patients without PD.

2 groups of patients of different age with varus deformity of lower extremities bones (19 patients with phosphate-diabetes (PD) and 36 patients without this disease) were examined. Control group consisted of 50 healthy female coevals. Patients with PD had. lag in lengthwise body growth, decrease of contractive ability of extremities' muscles, decrease of speed and power characteristics of locomotions, decrease of availability. Patients with,deformations of bones but without PD had. decrease of shin muscle power, weakening of balance function of a foot and. decrease of load, on foot segments while walking.
