Foot Muscles Training in Sclerosis

Primary outcomes

1. Four Square Step Test (FSST): dynamic stability assessment test.

   Time frame: Initial and after 8 weeks

   The test consists of drawing a cross on the floor, delimiting 4 squares. The subject is placed in square number 1 in front of square number 2. The objective is to enter as quickly as possible into each square following the following sequence: Square number 1, 2, 3, 4, 1, 4, 4, 3, 2 and 1. It measures time.

2. Six Spot Step Test (SSST): test that quantitatively assesses lower limb function

   Time frame: Initial and after 8 weeks

   The test field measured one meter (width) by five meters (length). In the middle of the width line (0.50 m), a cone was placed in the proximal and distal areas of the line (start point and finish point). On each lateral line, two cones were placed at distances of one and three meters on the left. Another two cones were placed at two and four meters on the right. The subjects were instructed to walk on alternating sides and to kick the cones, alternating between the medial and lateral sides of the same foot. The subjects were instructed to complete the test as quickly as possible, without running. It measures distance.

3. The Frailty and Injuries: Cooperative Studies of Intervention Tecnhiques (FICSIT-4 test): Test of static balance

   Time frame: 0-9 points. Initial and after 8 weeks

   Participants have to maintain four progressively difficult foot positions for 10 seconds each (side by side stance, semi-tandem stance, tanden stance, unipedal stance). It measures the ability to maintain posture without losing balance is evaluated.

4. Activities-specific Balance Confidence scale (AsBC)

   Time frame: Initial and after 8 weeks

   Evaluate the patient´s perceived of balance confidence during 16 different daily activities. 0%-100%
