Photobiomodulation Therapy on Pain and Range of Motion Following Flexor Tendon Repair

N/ACompletedNCT06761950

Cairo University44 enrolled

Overview

The purpose of the study was to evaluate the therapeutic effect of low-level laser in improving pain and ROM following flexor tendon repair surgery.

Flexor tendon injury is a common issue requiring early postoperative mobilization. Prolonged immobilization can lead to complications such as muscle atrophy, joint stiffness, osteoarthritis, infection, pain, joint cartilage ulceration, joint contracture, and tendon rupture. Low level laser therapy has been shown to accelerate inflammation, promote fibroblast proliferation, regulate procollagen messenger ribonucleic acid synthesis, accelerate bone repair and remodeling, encourage wound revascularization, and accelerate tissue repair. This study aims to evaluate the effectiveness of Low level laser therapy in pain management and improving range of motion after flexor tendon repair.

Interventions

Low Level laser therapyDEVICE

The patient received low-level laser therapy three times per week for four weeks, with immobilization maintained. The Mustang 2000 Laser device was used with an infrared laser probe to accelerate tendon healing. The device's specifications include peak power output of 15W, power density of 15W/cm2, wave length of 890nm, pulse frequency of 100Hz, spherical size of 0.002cm2, pulse duration of 130 ns, exposure duration of 60 sec, and energy density of 5.85J/cm2.

Placebo low level laser therapyDEVICE

Same as in the study group except turning on the device with covering probe by aluminum foil and ask patient to wear sun glasses to obtain the placebo effect 3 sessions per week for 4 weeks.

Outcomes

Primary Outcomes

Assessment of change of pain intensity

The Visual Analogue Scale is a 100mm line used for pain measurement, validated for various conditions like sleep, anxiety, breathlessness, and pruritus intensity. It accurately reflects pain changes, is reusable, and sensitive to acute pain changes.

Time frame: At baseline and after 4 weeks

Secondary Outcomes

assessment of change of active range of motion of metacarpophalangeal joint

Goniometers, typically made of plastic or metal, measure the degree of motion in a single plane by aligning a stationary arm, a movable arm, and a fulcrum with the joint axis. it was used to measure the active range of motion of metacarpophalangeal joint when the patient is in a sitting position.

Time frame: At baseline and after 4 weeks

assessment of change of active range of motion of proximal interphalangeal joint

Goniometers, typically made of plastic or metal, measure the degree of motion in a single plane by aligning a stationary arm, a movable arm, and a fulcrum with the joint axis. it was used to measure the active range of motion of proximal interphalangeal joint when the patient is in a sitting position.

Time frame: At baseline and after 4 weeks

assessment of change of active range of motion of distal interphalangeal joint

Goniometers, typically made of plastic or metal, measure the degree of motion in a single plane by aligning a stationary arm, a movable arm, and a fulcrum with the joint axis. it was used to measure the active range of motion of distal interphalangeal joint when the patient is in a sitting position.

Time frame: At baseline and after 4 weeks
