Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention:
1. An interview
2. Instruction of the measurement and testing procedures
3. Signing the consent for participant
4. Podological examination of the arch of the foot and angle of hallux.
5. Electromyographic examination of pelvic rim and hip muscles strength
6. Examination of pelvic tilt usingan electronic inclinometer
7. Motor control muscles activation techniques:
A. Technique one:
Patient: side-back lying with the knees extended on the table, with one hand on the gluteus medius for feedback.
Therapist: stands behind patients back and perform activation of gluteus medius using abduction and external rotation of the patients hip without back compensation.
B. Technique two:
Patient: prone lying with the knees extended on the table, with a hand on gluteus maximus for feedback.
Therapist: stands at the level of the patient performs muscle activation using extension of the treating hip without compensation on the lumbar spine.
C. Technique three:
Patient: supine lying with knees flexed at 60 degrees with feet resting on the wall. Legs position with neutral rotation of hips. Patients hand lying on the medial head of quadriceps femoris.
Therapist: Stands at the level of the patient, performing muscle activation using hands pressure towards the treated knee to the abduction and flexion of the hip, which should activate and the medialis head of quadriceps.
D. Technique four:
Patient: Standing position back to the wall, with neutral rotation of the hips, and feet together.
Therapist: Instructs how to perform the reciprocal braking of tensor fasciale latae using active posterior rotation of the pelvis, without compensation at the rest of the body.
Patient needs to hold the position in 30 seconds.

E. Technique five:
Patient: Stand back to a table, treated leg has flexed knee, and foot based on table.
Therapist: Instructs how to perform the reciprocal braking of rectus femoris using posterior rotation of the pelvis without compensation of the rest of the body. Patient need to hold the position for 30 seconds.
7. One group receives all techniques + toe sepatarors, second group receives all techniques with instructions how to perform correct movement in exercise, but without focusing on reciprocal braking and muscle activation - just instruct how to perform movement + toe separators, using the same time of exercise as group 1.
8. Treatment for group 1 and 2 administres physiotherapist
9. Mode of administration is individual face-to-face sessions
10. Treatment sessions will take 30 minutes per day, five sessions per week for 10 weeks for group one and group two.
11. Treatment will be assessed by physiotherapist using podological examination of the arch of the foot and angle of hallux; pelvic tilt examination, and electromyographic examination of pelvic rim and hip muscles strength
12. Instructions will be given by physiotherapist to the patients.
13. Toe separators are made of gel, size: 3,5cm x 2cm x 1,2cm x 1,9cm

Summary
Brief summary
The main scientific aim of the project is an objective evaluation of the influence of motor control exercises of pelvic rim and hip muscles on angle of hallux valgus. In physiotherapeutic practice, every tissue is important and may give responses at the other side of body. The relationship inbetween foot and pelvis is the key point to achive the physiological balance of human body. The lack information about right motor control of the muscles of pelvis rim and hip and it's influence to the lower extremities led the authors to conduct this study. The target population in this study will be people with hallux valgus.
