An observational study in Lateral Epicondylitis, Medial Epicondylitis and Obsessive-Compulsive Symptoms, sponsored by Fatih Turkmensoy. Not yet recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-02.
Sponsored by Fatih Turkmensoy · Observational
This study will compare obsessive-compulsive symptoms in adults with medial and/or lateral elbow epicondylitis (pain and tenderness on the inner and/or outer side of the elbow).
The study will include 90 participants in two groups of 45. One group will have no identifiable history of mechanical loading associated with their elbow condition. The other group will have a history of activities that place repeated strain on the elbow, such as manual work, sports, or caregiving. Group assignment will be based on medical history and clinical assessment, rather than random allocation.
Each participant will complete the Turkish self-report Yale-Brown Obsessive Compulsive Scale and the 37-item Turkish Maudsley Obsessional Compulsive Inventory once, at the study visit. The main outcome will be the Yale-Brown total score. The Maudsley total score will be a secondary outcome.
The study will assess symptoms, not establish a diagnosis of obsessive-compulsive disorder. No treatment will be assigned as part of the study, and no follow-up visits are planned.
This single-center observational study will recruit eligible, consenting adults consecutively until each group includes 45 participants. Data collection will take place over approximately six months, with each participant assessed at a single visit.
Clinical diagnosis of lateral epicondylitis will be based on tenderness elicited by palpation over the origin of the extensor carpi radialis brevis at the lateral epicondyle. Medial epicondylitis will be diagnosed by tenderness elicited by palpation over the medial epicondyle. Participants may have medial, lateral, or both forms of epicondylitis. Imaging confirmation and a minimum symptom duration will not be required.
The presence or absence of a history of mechanical loading associated with epicondylitis will be determined from the participant's history and clinical assessment, without a predefined duration or frequency threshold.
Participants will complete both questionnaires themselves. A psychiatrist who is unaware of group membership will score the coded questionnaires. Participant identity and group information will be maintained separately from the questionnaires and will be accessible only to the principal investigator.
296 studies on the registry are indexed under Tennis Elbow; 64 are open to participants now.
This study's planned enrollment of 90 is close to the median of 90 across 29 observational studies indexed under Tennis Elbow.

Adults aged 18 years or older presenting to the Orthopaedics and Traumatology outpatient clinic at Bursa Yuksek Ihtisas Training and Research Hospital with clinically diagnosed medial and/or lateral elbow epicondylitis. Eligible patients who provide written informed consent will be enrolled consecutively until each group includes 45 participants. Groups will be defined by the presence or absence of an identifiable history of associated mechanical loading, based on participant history and clinical assessment.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

Adults with clinically diagnosed medial and/or lateral elbow epicondylitis and no identifiable history of associated mechanical loading, based on participant history and clinical assessment. This group will include 45 participants. Each participant will complete the Turkish self-report Yale-Brown Obsessive Compulsive Scale and the 37-item Turkish Maudsley Obsessional Compulsive Inventory once at enrollment.

Turkish Self-Report Yale-Brown Obsessive Compulsive Scale Total Score
The total score will be compared between participants with and without an identifiable history of mechanical loading associated with epicondylitis. The self-report scale contains 10 items, each scored from 0 to 4, yielding a total score of 0 to 40. Higher scores indicate greater obsessive-compulsive symptom severity. Participants rate symptoms experienced during the preceding week. The questionnaire will be completed by participants and scored by a psychiatrist unaware of group membership. Scores will be used to assess symptoms, not to establish a diagnosis of obsessive-compulsive disorder.
Time frame: At enrollment (single study visit)
37-Item Turkish Maudsley Obsessional Compulsive Inventory Total Score
The total score will be compared between participants with and without an identifiable history of mechanical loading associated with epicondylitis. The 37-item Turkish self-report inventory uses true/false responses and yields a total score from 0 to 37. Higher scores indicate more obsessive-compulsive symptoms. Participants will complete the questionnaire once, and a psychiatrist unaware of group membership will score it. The score will not be used to establish a diagnosis of obsessive-compulsive disorder.
Time frame: At enrollment (single study visit)
