Summary

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.

Detailed description

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.

Conditions

• Photobiomodulation Therapy
• Low Level Laser Therapy
• Flexor Tendon Rupture
• Flexor Tendon Repair

Interventions

Type	Name	Description
DEVICE	Low Level laser therapy	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.
DEVICE	Placebo low level laser therapy	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.
OTHER	medical treatment	the patients received their drugs from their treating physicians
OTHER	physical therapy program	patients received the traditional program after flexor tendon repair involving isometric exercise, stretching and mobilizations
