About this study

Official title: Effects of Adding Platelet-Rich Plasma (PRP) Therapy to Extracorporeal Shock Wave Therapy (ESWT) in Patients With Lateral Epicondylitis: Double-Blind Randomized Sham-Controlled Study

The aim of this study is to determine the effectiveness of adding PRP or Sham PRP injection to ESWT treatment in patients with lateral epicondylitis on pain, muscle strength, functional activities, quality of life and work activities, and to determine the superiority of the treatments over each other.

Read the detailed description

Lateral epicondylitis (LE) is one of the most common elbow problems. It is characterized by pain in the lateral epicondyle of the humerus and on the surface of the extensor muscles of the forearm. It is seen in those who perform activities involving repetitive forced wrist extension and can lead to chronic pain syndrome.

Various treatment methods are used in the treatment of LE in order to reduce the patient's pain and increase his/her functional capacity. There are more than 40 treatment methods in the literature such as oral and local non-steroidal anti-inflammatory drugs (NSAID), cold application, deep friction massage, stretching and strengthening exercises, ultrasound, laser, ESWT, corticosteroid/botulinum toxin/glucosamine/autologous blood/platelet rich plasma (PRP) injections, prolotherapy, acupuncture, manipulation, and surgery.

Extracorporeal shock wave therapy (ESWT) is a method that aims to provide treatment by focusing high amplitude sound waves on the area of the body to be applied.

PRP is an autologous concentration of human platelets in a small volume of plasma produced by centrifuging a patient's own blood.

This study was designed as a double-blind, prospective, placebo-controlled, randomized study. Participants were randomized into 3 groups: ESWT + therapeutic exercise, ESWT + Sham PRP injection + therapeutic exercise, ESWT + PRP injection + therapeutic exercise.

Visual Pain Scale (VAS), Patient Rated Tennis Elbow Evaluation (PRTEE), Quick Disabilities of the Arm, Shoulder and Hand Score (Quick DASH), SF (Short form) -36 Quality of Life Scale, Handgrip strength with Jamar hydraulic hand dynamometer, Common extensor tendon thicknesses, peritendinous fluid, bone irregularities, calcifications, and diffuse tendon heterogeneity with ultrasound, upper extremity muscle strength with Isomed 2000 isokinetic device will be evaluated.

It was planned that the evaluations were made and recorded by a blinded physician to the groups at the beginning of the treatment, at the 4th week and at the 12th week controls.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ESWT+ExerciseOther

    Radial ESWT treatment will be applied to patients for 3 weeks, once a week for a total of 3 sessions. Radial shock waves will be applied in circular motions by applying gel on the epicondylar area where the most pain and sensitivity is. In each session, 8 Hz, 2.0 bar, 2000 beats will be applied.

    Therapeutic Exercise:

    All patients will be taught a home exercise program including stretching and eccentric strengthening exercises by an experienced physiotherapist. The eccentric exercises consisted of the following: three sets of 10 repetitions for wrist and elbow flexion; two sets of 10 repetitions for wrist extension strengthening, starting with 50% of maximum strength and density and increasing the resistance each week; and finally, two sets of 10 repetitions for the wrist flexor and extensor muscle groups comprising 20s of stretching and 10s of relaxing using the unaffected hand. Exercise program will be done twice a day for 3 months.

  • PRP+ESWT+ExerciseProcedure or surgery

    Radial ESWT treatment will be applied to patients for 3 weeks, once a week for a total of 3 sessions. Radial shock waves will be applied in circular motions by applying gel on the epicondylar area where the most pain and sensitivity is. In each session, 8 Hz, 2.0 bar, 2000 beats will be applied.

    Therapeutic Exercise:

    All patients will be taught aforementioned home exercise program. Exercise program will be done twice a day for 3 months.

    Procedure:

    10 ml of venous blood taken from the patients will be put into the T-LAB® PRP kit (T-Biotechnology Laboratory, İstanbul, Turkey) and will then be centrifuged. Approximately 3 cc of the PRP obtained will be applied to the tendinosis area under USG guidance. All injections will be performed with long axis in-plane technique, using the ultrasound device (Esaote My Lab 70 XVision 6-18 Mhz linear probe).

  • Sham PRP+ESWT+ExerciseProcedure or surgery

    Radial ESWT treatment will be applied to patients for 3 weeks, once a week for a total of 3 sessions. Radial shock waves will be applied in circular motions by applying gel on the epicondylar area where the most pain and sensitivity is. In each session, 8 Hz, 2.0 bar, 2000 beats will be applied.

    Therapeutic Exercise:

    All patients will be taught aforementioned home exercise program. Exercise program will be done twice a day for 3 months.

    Procedure:

    In Sham-PRP group,10 ml of venous blood will be taken and after the same waiting time 3 cc of 0.9% saline will be injected to the tendinosis area under USG guidance. All injections will be performed with long axis in-plane technique, using the ultrasound device (Esaote My Lab 70 XVision 6-18 Mhz linear probe).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline visual analog scale (VAS) elbow pain at 4th and 12th week

    Pain intensity was measured with visual analogue scale for pain (0-10 mm; 0 means no pain, 10 means severe pain) which is used to measure musculoskeletal pain with very good reliability and validity. The patient will be asked to score rest, movement, and nighttime pain.

    Measured: baseline and 12th week

Secondary outcomes (5)
  1. Change from baseline Handgrip strength at 4th and 12th week

    Measuring hand grip strength is an objective method for evaluating response to treatment and functional recovery. Grip strength will be evaluated with the Jamar hydraulic hand dynamometer. Patients will be asked to squeeze with maximum force and each measurement will be made three times, and their averages will be recorded in kg. The dynamometer has a dual scale readout which displays isometric grip force from 0-90 kg. Higher scores means better grip strength.

    Measured: baseline and 12th week

  2. Change from baseline Quick Disabilities of the Arm, Shoulder and Hand Score (Quick DASH) at 4th and 12th week

    Quick DASH is a questionnaire that can be used to evaluate disability, activity restriction and work participation restriction caused by musculoskeletal problems involving the upper extremity. The QuickDASH tool uses a 5-point Likert system (1: no difficulty, 2: mild difficulty, 3: moderate difficulty, 4: extreme difficulty, 5: not able to do at all) from which the patient can mark an appropriate number corresponding to his/her severity/function level. According to the results of the Quick DASH questionnaire, a score between 0-100 is obtained from each section and a higher score indicates greater disability.

    Measured: baseline and 12th week

  3. Change from baseline quality of life (Short Form 36 (SF-36)) at 4th and 12th weeks

    This is a self-administered scale, which is widely used to measure the quality of life. It was developed to measure the quality of life in patients who have physical illnesses; however, it can also be successfully used in healthy individuals and patients who have psychiatric diseases. SF-36 includes 36 items and surveys eight domains of health. Total score was between 0 (disability) and 100 (no disability). Every subgroup of the questionnaire has a score scale between 0 and 100. Every increase in the subgroup of SF-36 questionnaire, which is a positive scoring system, indicates increase in quality of life related to health.

    Measured: baseline and 12th week

  4. Change from baseline Ultrasonographic examination at 4th and 12th weeks

    Ultrasonographic examination will be made using the Esaote My Lab 70 XVision 6-18 Mhz linear probe. Before the treatment, patients will be evaluated for tendinosis of the common extensor tendon (extensor carpi radialis brevis, extensor carpi ulnaris, extensor digitorum, extensor digiti minimini tendons) by a physician experienced in the field of ultrasound, as gray scale and color Doppler activity.

    Measured: baseline and 12th week

  5. Change from baseline upper extremity muscle strength with isokinetic device at 4th and 12th weeks

    Isokinetic systems are complex systems used for both rehabilitation and patient evaluation. Isokinetic contraction; It is defined as contraction at a constant rate throughout the entire range of motion and at an equal rate at all angles of motion. Wrist extensor strength isokinetic strength assessment will be performed by a physiotherapist who is trained in using the isokinetic device (IsoMed 2000, isokinetic dynamometer, Germany) and has at least 5 years of experience.

    Measured: baseline and 12th week
