Lateral EpicondylitisNCT07667491
Effects of 8 Weeks of Two Exercise Programs on Risk Factors Associated With Epicondylitis in Amateur Padel Players
A study testing Strenght exercises in people with Lateral Epicondylitis and Prevention, run by School of Allied Health Sciences of Porto (ESTSP) - Polytechnic Institute of Porto (IPP) at 1 site in Portugal.
Trial summary
Background: The physical demands of padel can increase the risk of injuries, particularly lateral epicondylitis in the elbow. Key risk factors include deficits in forearm muscle strength and rotator cuff weakness. Prevention programs focus on forearm strengthening, with no studies on rotator cuff strength.

About this study
Background: The physical demands of padel can increase the risk of injuries, particularly lateral epicondylitis in the elbow. Key risk factors include deficits in forearm muscle strength and rotator cuff weakness. Prevention programs focus on forearm strengthening, with no studies on rotator cuff strength. This study aims to compare two exercise programs designed to reduce risk factors for lateral epicondylitis in amateur padel athletes, specifically wrist extensor strength, grip strength, and rotator cuff strength.
Read the detailed description
A sample of 45 amateur padel athletes was allocated to a conventional exercise group (n = 15), a rotator cuff exercise group (n = 15), or a control group (n = 15). The first two groups performed two strengthening exercises, one common to both groups (wrist extension) and one group-specific exercise (forearm supination-pronation or the Y exercise). The control group did not perform any intervention. Participants were assessed at baseline (T0) and post-intervention (T1). Muscle strength was measured using the ActivForce 2 hand-held dynamometer. Outcome measures included wrist extensor strength, grip strength, shoulder internal rotation strength, shoulder external rotation strength, shoulder abduction strength, and the isometric external-to-internal rotation ratio (ER:IR).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Strenght exercisesOther
Both exercise groups participated in two independent sessions per week for a du-ration of 8 weeks. Each session consisted of two strength exercises, with participants completing 3 sets of 10 repetitions of two strength exercises with 1-2 minutes of rest between sets
| Study group | Role | What they receive |
|---|---|---|
| Conventional Exercise Group | Experimental | Participants performed wrist extension and forearm supination-pronation strengthening exercises using dumbbells for 8 weeks. Receives: Other: Strenght exercises |
| Rotator Cuff exercise Group | Experimental | Participants performed wrist extension strengthening exercises using dumbbells and the Y exercise targeting the rotator cuff for 8 weeks. Receives: Other: Strenght exercises |
| Control Group | No intervention | Participants did not receive any exercise intervention during the study period. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Peak Force
maximum force across the multiple repetitions of the test - for wrist extension, grip strength, and rotator cuff strength (shoulder internal rotation (IR), shoulder ex-ternal rotation (ER), and shoulder abduction (ABD)), assessed using the ActivForce2 digital dynamometer.
Measured: From enrollment to the end of treatment at 8 weeks
Secondary outcomes (1)
ER:IR Isometric Ratio
calculated based on the results of the shoulder internal and external rotation PF tests
Measured: From enrollment to the end of treatment at 8 weeks

The record lists 1 site in Portugal. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Peak Force (time frame: From enrollment to the end of treatment at 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jun 2026.
