Effects of Upper Extremity Manual Lymphatic Drainage on Symptom Severity, Hand Functions, Electrophysiological and Ultrasonographic Measurements in Carpal Tunnel Syndrome

Istanbul Medeniyet University27 enrolled

Overview

This study is aimed to investigate the effects of upper extremity manual lymphatic drainage, which is applied to remove edema from the carpal tunnel region in addition to conventional exercise therapy in Carpal tunnel syndrome patients on findings of clinical, ultrasonographic, and electrophysiological.

Thirtyfour volunteer participants between aged 40 and 60 years, who met the inclusion criteria, will be included in the study. Participants will be randomly divided into two groups experimental and control groups. While the control group will receive only conventional exercises, the experimental group will receive both conventional exercises and upper extremity manual lymphatic drainage. A total of 3 measurements will be made before the treatment, after the treatment and 1 month after the end of the treatment. Symptom severity will be evaluated via Boston carpal tunnel syndrome questionnaire, grip strength via hand dynamometer, pressure pain threshold via digital algometer device, cross-sectional area of the median nerve via ultrasound, and median nerve conduction velocity via superficial EMG device.

Interventions

manual lymphatic drainage (MLD)OTHER

MLD is a manual technique that is applied to the lymphatic system with a pressure of approximately 40-50mmHg and increases the working speed of lymphatic nodules/collectors. Its main purpose is to support microcirculation by accelerating lymphatic flow and to prevent/remove interstitial fluid accumulation that may cause fascial adhesions.

Inclusion Criteria: * People aged between 40-60 years * Having been diagnosed with carpal tunnel syndrome (CTS) at least 6 months ago or having symptoms related to carpal tunnel syndrome for at least 6 months * Having mild (median nerve sensory conduction velocity below 40 m/sec) and moderate (median nerve sensory conduction velocity below 40 m/sec and median motor distal latency 4 ms and above) CTS according to electrophysiological findings * Not having received medical treatment and/or physiotherapy for CTS in the last 6 months Exclusion Criteria: * Having cervical radiculopathy * Having thoracic outlet syndrome * Presence of systemic disease that may lead to CTS, such as diabetes or thyroid disease * Pregnancy * Presence of anemia * Having a history of CTS surgery * Presence of radial or ulnar nerve sensory-motor lesions accompanying the present condition * Presence of lymphedema * Having severe (Sensory nerve action potential cannot be obtained) and severe (Sensory nerve action potential cannot be obtained, but combined muscle action potential is not present) CTS according to electrophysiological findings

Outcomes

Primary Outcomes

Symptom severity

1- Symptom severity will be evaulated with Boston carpal tunnel questionnaire (BCTQ). BCTQ comprises 11 items of Symptom Severity Scale (SSS) measuring pain, paresthesia, numbness, nocturnal symptoms and feeling of weakness plus another 8 items of Functional Status Scale (FSS) measuring difficulties in performing daily activities. Scales ranged from 1-5 representing normal to worst symptoms or disabilities. Higher scores indicate greater symptom severity and disability.

Time frame: Change from baseline symptom severity at week 6 and 10.

Grip strength

2- Grip strength will be assessed with a digital hand dynamometer. The subject will seat with feet positioned on the floor, shoulder adducted, and the elbow bent at a 90-degree angle with the forearm parallel to the floor. Maximal isometric grip strength will be measured in kilograms. It is a reliable method for measuring grip strength.

Time frame: Change from baseline grip strength at week 6 and 10.

Pressure pain threshold (PPT)

PPT, the minimal amount of pressure where a sense of pressure changes to pain, will be measured with an electronic algometer over the median nerve in the wrist area. The pressure will be applied approximately at a rate of 30 kPa/sec for 30 seconds. Participants will be instructed to press the switch when the sensation changed from pressure to pain.

Time frame: Change from baseline pressure pain threshold at week 6 and 10.

Cross-sectional area of the median nerve

US images will be obtained by a neurologist trained in peripheral nerve US. The nerve will be imaged using a Biosound Esaote MyLab 70 equipped with an 18-MHZ linear-array transducer. The median nerve will be imaged in cross-section at the distal wrist crease (carpal tunnel inlet) and 12 cm proximal to this point in the forearm.

Time frame: Change from baseline cross-sectional area of the median nerve at week 6 and 10.

Sensory Velocity of median nerve
