Shock wave or ozone: which works better for stubborn tennis elbow?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age: Male or female patients between 18 and 65 years of age. * Clinical Diagnosis: Patients diagnosed with lateral epicondylitis, defined by pain in the lateral epicondyle region for more than 3 months, increased pain on palpation of the lateral epicondyle, and positive provocation tests (Cozen's, Maudsley's, or Mills' tests). * Symptom Duration: Presence of symptoms for more than 3 months (resistant cases). * Treatment Failure: Lack of response to first-line conservative treatments (e.g., analgesics, exercise, rest, splinting). * Radiographic Confirmation: No other pathology detected on direct radiographs of the elbow. * Injection History: No corticosteroid injection to the affected elbow within the last 6 months. * Consent: Voluntary participation in the study Exclusion Criteria: * Elbow Pathology: Presence of elbow problems other than lateral epicondylitis (e.g., loose bodies, rheumatoid nodules). * Surgical History: History of previous surgery on the affected elbow joint. * Structural Damage: Presence of tendon rupture. * Consent: Unwillingness to continue treatment or participate. * Spinal Pathology: Cervical root pathology (cervical radiculopathy). * Neuropathy: Diagnosed upper extremity entrapment neuropathy. * Neurological Status: Presence of neurological impairment or deficits. * Recent Injections: History of injection therapy to the elbow within the last 6 months. * Recent Therapy: History of physical therapy for the elbow region within the last 6 months. * Pregnancy: Pregnant women. * Hematological: Presence of coagulation or bleeding disorders. * Vascular: Presence of peripheral vasculopathy. * Pain Syndromes: Presence of Complex Regional Pain Syndrome (CRPS). * Oncology: History of malignancy. * Systemic Diseases: Presence of systemic inflammatory or autoimmune disorders (e.g., Rheumatoid Arthritis, SLE). * Trauma: History of direct trauma to the elbow. * Medication: Current use of medications that may affect pain levels or muscle strength (e.g., muscle relaxants, analgesics, gabapentinoids). * Local Infection: Presence of open wounds, infection, or signs of active inflammation in the elbow region. * Cooperation: Difficulty in cooperation or cognitive inability to follow instructions. * Enzyme Deficiency: Congenital Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency.
