Simple shot vs. guided shot: which works better for carpal tunnel?

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

Inclusion Criteria: * Age ≥18 years * Presence of typical CTS symptoms (numbness, tingling, paresthesias, or pain that may be provoked by nighttime or activity-related posture * VAS score of ≥ 3/10 * Symptom duration longer than 12 weeks * Positive Tinel's and/or Phalen's sign * Electrophysiologically mild or moderate CTS being diagnosed. * Volunteer to participate in study Exclusion Criteria: * Patients with shoulder, elbow, wrist, or finger problems (e.g., impingement syndrome, epicondylitis, history of fractures in the wrist, de Quervain's tenosynovitis, trigger finger, Complex Regional Pain Syndrome (CRPS), Dupuytren's contracture). * Patients with a history of trauma or surgery in the affected hand, or those with significant anatomical deformities. * Patients with systemic diseases such as rheumatological disorders, hypothyroidism, amyloidosis, diabetes, gout, or chronic kidney failure. * Patients with conditions that may mimic CTS, such as polyneuropathy, plexopathy, cervical radiculopathy, or thoracic outlet syndrome. * Patients with cognitive dysfunction or communication issues. * Patients with severe CTS, neurological deficits (e.g., thenar atrophy, muscle weakness in thumb abduction/opposition), or those requiring surgical intervention. * Patients who have received local steroid injections or physical therapy to the hand/wrist within the last 6 months. * Patients who are receiving or will receive another/additional treatment for CTS. * Pregnant or lactating women. * Patients with active malignancies or local/systemic infections. * Patients who are receiving any active treatment (e.g., NSAIDs, oral/intramuscular steroids, acupuncture, other pain medications). * Patients with upper extremity involvement due to first motor neuron damage (e.g., stroke-hemiplegia, tetraparesis, multiple sclerosis). * Patients with a bifid median nerve, persistent median artery, ganglion cyst, tenosynovitis, or tendinitis in the wrist. * Use of a wrist splint during the last 6 months. * Allergy to corticosteroids or local anesthetics, and blood diathesis
