Percutaneous Needle Electrolysis (PNE) in Soleus Injury

October 7, 2020 updated by: Blanca de la Cruz Torres, University of Seville

Effect of the Application of Ultrasound-guided Percutaneous Needle Electrolysis on the Chronic Soleus Injury in Dancers

This study evaluates if the physiotherapy treatment based on eccentric exercise, ultrasound-guided PNE or a combination of both therapies on chronic soleous injuries may cause changes in pain, functionality, dorsal flexion of the foot, balance and muscle fatigue in dancers.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Eccentric group
The dancers of this group wil perform a soleus eccentric exercise
Other: Eccentric exercise
soleus eccentric exercise
Experimental: PNE group

The dancers of this group will receive a PNE treatment, consisting of the application of galvanic current, by ultrasound.

The approach will be performed with a transverse axis with a needle orientation that will depend on the location of the target tissue. The parameters will be 3 mA, 3 seconds, 3 impacts (3: 3: 3). The periodicity will be 1day/7day/21day
Other: PNE
the application of galvanic current
Experimental: Combined group
The dancers of this group will receive a combined treatment and will be carried out in the same way as the other two groups.
Other: Combined
soleus eccentric exercise and PNE

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
change of pain level
Time Frame: Change from Baseline VAS at 3 months months
Visual Analogue Scale (VAS: 0=no pain; 100= pain as bad as can be
Change from Baseline VAS at 3 months months
Change of Lunge Test
Time Frame: Change from Baseline lunge test at 3 months months
This test measures the ankle range of motion. Less than 9/10 cm, range of motion will be considered restricted
Change from Baseline lunge test at 3 months months
Change of the Releve test
Time Frame: Change from Baseline releve test at 3 months months
During the unilateral balance test with open eyes, the participant will be asked to hold as much time as possible in the relay position (raised heel of the floor) on one leg
Change from Baseline releve test at 3 months months
Change of the Endurance test
Time Frame: Change from Baseline endurance test at 3 months months
The unilateral raised heel test. The dancer should repeatedly lift the heel from the floor to the maximum range of plantar flexion movement as many times as possible.
Change from Baseline endurance test at 3 months months
Change of the Balance test
Time Frame: Change from Baseline balance test at 3 months months
The test will be conducted with closed eyes, flat feet and barefoot participants and dancers will perform a retiré position. Participants will maintain the position as long as possible.
Change from Baseline balance test at 3 months months
Changes of the DFOS questionnaire
Time Frame: Change from Baseline DFOS questionnaire at 3 months months
This questionnaire measures the pain and function (0= bad; 90=well)
Change from Baseline DFOS questionnaire at 3 months months
Change of the Minimal Detectable Change (MCD)
Time Frame: Change from after treatment at 3 months months
The minimal detectable change is defined as a valid change in score that is not due to chance. Minimally clinically important difference (MCID), in comparison, goes beyond valid change to assess meaningful difference in dance function
Change from after treatment at 3 months months

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
