Official title
Effectiveness of Capacitive and Resistive Energy Transfer Therapy in Patients With Lateral Epicondylitis: A Sham-Controlled, Double-Blind Randomized Clinical Trial
Overview
This prospective, randomized, double-blind, sham-controlled clinical trial aims to evaluate the efficacy of Capacitive and Resistive Energy Transfer (TECAR) therapy in patients with lateral epicondylitis. Participants will be randomly assigned to either a TECAR plus exercise group or a sham TECAR plus exercise group. Both groups will receive a standardized home exercise program including elbow and wrist range-of-motion, stretching, eccentric strengthening, and handgrip strengthening exercises. The TECAR group will additionally receive active TECAR therapy, while the control group will receive sham TECAR treatment using the same device and treatment protocol without therapeutic energy delivery. Outcome assessments will be performed by a blinded evaluator at baseline, immediately after treatment, and at 1- and 2-month follow-up visits. The study aims to determine whether TECAR therapy provides additional benefits in pain relief, functional improvement, and clinical outcomes when combined with exercise therapy in patients with lateral epicondylitis.
Detailed description
This study is planned as a prospective, randomized, double-blind, sham-controlled clinical trial involving patients diagnosed with lateral epicondylitis who present to the Physical Medicine and Rehabilitation Outpatient Clinic of Gaziantep City Hospital.
Participants will be randomly allocated into two groups using a computer-generated randomization method:
* Group 1: TECAR therapy + exercise group * Group 2: Sham TECAR therapy + exercise group
All participants in both groups will receive a home-based exercise program consisting of elbow and wrist range-of-motion exercises, stretching exercises, eccentric strengthening exercises, and handgrip strengthening exercises. The exercise program will be explained in detail by a physiotherapist, and participants will be instructed to perform each exercise 10 repetitions, three times daily, throughout the treatment period. Adherence to the exercise program will be monitored through weekly telephone follow-ups and daily exercise log sheets completed by the participants at home. Compliance with regular splint use will also be monitored.
Outcome assessments will be conducted by a blinded evaluator at baseline, immediately after completion of treatment, and at the 1st and 2nd months following treatment.
TECAR Group (Active Treatment Group):
In addition to the exercise program, participants in the TECAR group will receive TECAR therapy consisting of a capacitive mode application at a frequency of 500 kHz for 5 minutes and a resistive mode application at a frequency of 500 kHz for 10 minutes, for a total treatment duration of 15 minutes per session. Treatment will be administered five sessions per week for two weeks, resulting in a total of 10 sessions. The capacitive mode will be applied to target superficial soft tissues, whereas the resistive mode will be used to affect deeper and higher-impedance connective tissues, such as the common extensor tendon.
Sham TECAR Group (Control Group):
Participants in the sham TECAR group will be treated using the same device, electrode, application area, treatment duration, and procedural protocol as the active treatment group. However, the device will be configured to deliver no therapeutic energy, thereby serving as a sham intervention.
Interventions
- Device TECAR Therapy + Exercise
Participants assigned to this group will receive active Capacitive and Resistive Electrical Transfer (TECAR) therapy in addition to a standard home exercise program. Active TECAR therapy will be administered five times a week for two weeks (10 sessions in total), with each session lasting 15 minutes. - Device Sham TECAR Therapy + Exercise
Participants assigned to this group will receive sham TECAR therapy in addition to the same standardized home exercise program. The sham intervention will be delivered using the same device, applicator, treatment duration, and application procedures as the active treatment; However, no therapeutic energy will be delivered.
Primary outcome measures
- Visual Analog Scale (VAS) [Time frame: Baseline (pre-treatment), Week 2 (post-treatment), Week 6 (1-month follow-up), and Week 10 (2-month follow-up).]
Secondary outcome measures (5)
- Pressure Pain Threshold Measurement with Algometry [Time frame: Baseline (pre-treatment), Week 2 (post-treatment), Week 6 (1-month follow-up), and Week 10 (2-month follow-up).]
- Ultrasonographic evaluation [Time frame: Baseline (pre-treatment), Week 2 (post-treatment), Week 6 (1-month follow-up), and Week 10 (2-month follow-up).]
- Handgrip Strength [Time frame: Baseline (pre-treatment), Week 2 (post-treatment), Week 6 (1-month follow-up), and Week 10 (2-month follow-up).]
- The Patient-Rated Tennis Elbow Evaluation (PRTEE) [Time frame: Baseline (pre-treatment), Week 2 (post-treatment), Week 6 (1-month follow-up), and Week 10 (2-month follow-up).]
- Quick Disabilities Of The Arm, Shoulder And Hand (Quick-DASH) [Time frame: Baseline (pre-treatment), Week 2 (post-treatment), Week 6 (1-month follow-up), and Week 10 (2-month follow-up).]
