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

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.

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.

the patients received their drugs from their treating physicians

patients received the traditional program after flexor tendon repair involving isometric exercise, stretching and mobilizations
