Comparative Research Among 3 Action Protocol in Other to Approach Chronic Patellar Tendinopathy

Study Overview
=================
Brief Summary
-----------------
The accomplishment of a treatment with Intratissue Percutaneous Electrolysis of additional form to the accomplishment of eccentric exercise's program in patients with chronic patellar tendinopathy is more effective than the accomplishment of an additional treatment with dry needling or eccentric exercise's program realized of isolated form.

Detailed Description
-----------------
Experimental study randomized with double blind, whose purpose is to compare three protocols in those who apply different protocols of physical therapy to themselves in three groups of intervention with patients with chronic patellar tendinopathy. There take part in this study young women of both sexes, of Zaragoza and of different sports clubs of entity 18 and 40 years, that they realize of habitual form (minimum 3 times a week) a sport. All of them present chronic patellar tendinopathy.

Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Group of Dry Needling<br>They will receive a treatment of dry needling with ultrasound scan together with a treatment in which they will realize eccentric exercise's program that the patient will have to realize in his domicile. The needle will get in the relevant zone of treatment. The punction will be realized using the technique of entry - Hong's rapid exit. Three punction will realize in the disabled zone of 3 seconds of duration. | Other: Group of Dry Needling<br>* Every group will receive a total of 4 treatment distributed throughout 8 weeks of treatment. The program of eccentric exercises that will have to realize it in his domicile every day.<br>|
| Active Comparator: Group of electrolysis<br>They will receive a treatment of Intratissue Percutaneous Electrolysis with ultrasound scan together with a treatment in which they will realize eccentric exercise's program that the patient will have to realize in his domicile. The needle will get in the relevant zone of treatment. An intensity of 3 milliampere will be in use, during 3 seconds and one will repeat 3 times. | Other: Group of Electrolysis<br>* Every group will receive a total of 4 treatment distributed throughout 8 weeks of treatment. The program of eccentric exercises that will have to realize it in his domicile every day.<br>|
| Placebo Comparator: Control Group<br>They will receive a treatment of punction placebo with ultrasound scan together with a treatment in the one that will realize eccentric exercise's program that the patient will have to realize in his domicile. | Other: Control Group<br>* Every group will receive a total of 4 treatment distributed throughout 8 weeks of treatment. The program of eccentric exercises that will have to realize it in his domicile every day.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline in functionality at 8 weeks as measured by Visa-p | This scale consists of eight questions, the first six questions of which employ an analogical visual scale in order to assign a score of 0 to 10, where 10 represents the optimum state, for the purpose of quantifying pain and function in different activities, whereas the last two questions assess the level of functionality and ability to perform physical activity. | 8 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain, as measured by Visual Analog Scale | Participants will be explained that a score of 0 indicates the absence of pain whereas a score of 10 represents the maximum tolerable pain | 0, 8 and 20 weeks | 
| Quality of life by SF-36 | Health Survey | 0, 8 and 20 weeks | 
| Thickness of the tendon, as measured by ultrasound scan | Tendon structure | 0, 8 and 20 weeks | 
| Height of the jump | Jump test with a force platform | 0, 8 and 20 weeks | 
| Concentric force of the low members | Jump test with a force platform | 0, 8 and 20 weeks | 
| Speed of the jump | Jump test with a force platform | 0, 8 and 20 weeks | 
| Hypervascularity, as measured by ultrasound scan | Tendon structure | 0, 8 and 20 weeks | 
| Functionality, as measured by Visa-p | This scale consists of eight questions, the first six questions of which employ an analogical visual scale in order to assign a score of 0 to 10, where 10 represents the optimum state, for the purpose of quantifying pain and function in different activities, whereas the last two questions assess the level of functionality and ability to perform physical activity. | 0 and 20 weeks |
