Effects of Motor Imagery in Pain Modulation and Median Nerve Mechanosensitive in Healthy Patients

Study Overview
=================
Brief Summary
-----------------
The aim of this study are 1) to determinate the effectiveness of motor imagery or strength training in differens aspects of pain modulation. 2) evaluate the functional improvement of the hand by a motor imagery protocol.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Action observation<br>The patients will observe a 25 minutes clip of neurodynamic exercises of the hand. | Other: Mirror therapy<br>* With a mirror glasses on, do the neurodynamic exercises with the non-dominant hand while the patient is looking at the dominant hand<br>Other: Neurodynamic exercises<br>* active movement of the dominant hand. Do neurodynamic exercises.<br>Other: Strength<br>* Execute a short strength training for the dominant hand<br>|
| Experimental: Mirror Therapy<br>With a mirror glasses, the patients will execute neurodynamic movements of their non-dominant hand during 25 minutes. | Other: Action observation<br>* look at a clip of a hand doing neurodynamic exercises.<br>Other: Neurodynamic exercises<br>* active movement of the dominant hand. Do neurodynamic exercises.<br>Other: Strength<br>* Execute a short strength training for the dominant hand<br>|
| Active Comparator: Strength Training<br>Strength protocol for the dominant hand. | Other: Action observation<br>* look at a clip of a hand doing neurodynamic exercises.<br>Other: Mirror therapy<br>* With a mirror glasses on, do the neurodynamic exercises with the non-dominant hand while the patient is looking at the dominant hand<br>Other: Neurodynamic exercises<br>* active movement of the dominant hand.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Conditioned pain modulation | Diffused noxious inhibitory control system will be measure with tourniquet test | Change from baseline at 2 weeks | 
| Pressure pain threshold | Three consecutive trials of pressure pain threshold on the active trigger point at a rate of 1 kg/sec at intervals of 30 seconds were conducted. | Change from baseline at 2 weeks | 
| Cold hyperalgesia | 10 seconds of a cold pack and after that, rating the pain from 0 to 10 | Change from baseline at 2 weeks | 
| Neural mechanosensitive | Upper Limb Neurodynamic test 1 (ULNT1) | Change from baseline at 2 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Strength_grip | grip strength without pain | Change from baseline at 2 weeks | 
| Imagine movement capacity | testing the capacity of imagine that their own body is movement. Movement Imagery Questionnaire-Revised (MIQ-R questionaire). top score 56 and bottom score 8. The higher values indicates a better outcome. | Change from baseline at 2 weeks | 
| Psychological factors_Anxiety | State Trait Anxiety Inventory (STAI-T). Top score 60 and bottom score 0. The higher values indicate worst outcomes. | Change from baseline at 2 weeks | 
| Psychological factors_Depression | Beck Depression Inventory (BDI-II). the scores goes from 0 to 63. The higher values indicate worst outcomes. Beck Depression Inventory (BDI-II) Beck Depression Inventory (BDI-II) | Change from baseline at 2 weeks | 
| Psychological factors_Kinesiophobia | Tampa Scale for Kinesiophobia. Total scores goes from 11 to 44.The higher values indicate worst outcomes. | Change from baseline at 2 weeks |
