AIM: A new type of footwear without heel support is presented, which helps to correct the posture in subjects suffering from spinal pain. The suggested support compels the subject to normalize the physiological curves of the spine. The aim of this study is to demonstrate that the weight distribution of the plantar support on the front foot and the increase of weight in the plantar arch during walk also provides the functional power of the calf muscles and therefore of the peripheral venous-muscular pump (PVMP).
METHODS: Sixty subjects aged 22-66 years (mean age 45.32 years), 16 males, 44 females with a total of 120 limbs were selected and divided into 5 groups: 66 without skeletal alterations and venous reflux: normals; 22 with invalidating skeletal alterations: orthopaedics; 18 with venous reflux: phlebopathics; 4 with skeletal alterations and venous reflux: mixed; 10 with foot alterations and/or obesity. The subjects were examined through digital Photoplethysmography (DPPG): the relliring time (T°) and the pump capacity (VO%) were calculated 10 seconds after walking on a mobile platform with and without footwear.
RESULTS: An increase in the VO% was observed in 106 limbs (p=0.0027) in the group first (p=0.0317) and in the second group (p=0.0341). In the third group the T° was increased (p=0.0317). In fourth group the parameters did not change. Fifth group resulted in a deterioration in the haemodynamic values.
CONCLUSIONS: In subjects without muscular-skeletal alterations the footwear determines an immediate and significant increase in the PVMP capacity in normal and orthopaedic cases and a significant increase of T° in phlebopathies. The FW can be a valid and active support in the phlebological prevention and in the rehabilitation of the phlebopatic subjects.
