Effects of the Proprioceptive Neuromuscular Facilitation for Promoting Muscular Irradiation

Study Overview
=================
Brief Summary
-----------------
This study aims to evaluate the effects of Proprioceptive Neuromuscular Facilitation (PNF) patterns delivered to the upper limb, lower limb and trunk for promoting motor irradiation to the contralateral lower limb.

Conditions
-----------------
Motor Disorders

Intervention / Treatment
-----------------
* Other: Upper Limb pattern with flexion - abduction - external rotation
* Other: Lower Limb pattern with flexion - adduction - external rotation with knee flexion
* Other: Lower Limb pattern with flexion - abduction - internal rotation with knee flexion
* Other: Lifting to the right
* Other: Sit to Stand

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Upper limb pattern<br>Upper Limb pattern with flexion - abduction - external rotation | Other: Upper Limb pattern with flexion - abduction - external rotation<br>* The PNF pattern will be applied three times. Participants will be in supine position under a stretcher, with arms folded and lower limbs in neutral position. In order to induce irradiation for the contralateral lower limb, the left foot sole will be kept in contact with the wall. For EMG recording, the participant will be positioned at the end of the PNF pattern and then the isometric contraction will be solicited. The command used was: do not let me move you.<br>|
| Experimental: Lower limb pattern 1<br>Lower Limb pattern with flexion - adduction - external rotation with knee flexion; | Other: Lower Limb pattern with flexion - adduction - external rotation with knee flexion<br>* The PNF pattern will be applied three times. Participants will be in supine position under a stretcher, with arms folded and lower limbs in neutral position. In order to induce irradiation for the contralateral lower limb, the left foot sole will be kept in contact with the wall. For EMG recording, the participant will be positioned at the end of the PNF pattern and then the isometric contraction will be solicited. The command used was: do not let me move you.<br>|
| Experimental: Lower limb pattern 2<br>Lower Limb pattern with flexion - abduction - internal rotation with knee flexion; | Other: Lower Limb pattern with flexion - abduction - internal rotation with knee flexion<br>* The PNF pattern will be applied three times. Participants will be in supine position under a stretcher, with arms folded and lower limbs in neutral position.

| Active Comparator: Sit to Stand<br>Sit to Stand task | Other: Sit to Stand<br>* Subjects will be sitting on a chair without armrests with ankles positioned at approximately 10 degrees of dorsiflexion. Knees will be kept at approximately 100 degrees of flexion. During the task, the participant will be instructed to stand from the sitting position while keeping their arms crossed over the chest. The examiner will give the command ready - set - go. The task will be performed three times.<br>|
