Conditions

Outcome Measures

Primary Outcomes (1)

  • 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.

    At baseline and after 4 weeks

Secondary Outcomes (3)

  • assessment of change of active range of motion of metacarpophalangeal joint

    At baseline and after 4 weeks

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

    At baseline and after 4 weeks

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

    At baseline and after 4 weeks

Study Arms (2)

Low Level Laser Therapy

EXPERIMENTAL

This group included 22 patients with zone II, and III flexor tendon injuries whom have pain and limited range of motion post flexor tendon repair surgery and received low-level laser therapy, 3 sessions per week, for a period of 4 weeks in addition to their physical therapy program and medical treatment

Device: Low Level laser therapyOther: medical treatmentOther: physical therapy program

ACTIVE COMPARATOR

This group included 22 patients with zone II, and III flexor tendon injuries whom have pain and limited range of motion after flexor tendon repair surgery and received placebo low-level laser therapy, 3 sessions per week for 4 weeks in addition to their physical therapy program and medical treatment.

Device: Placebo low level laser therapyOther: medical treatmentOther: physical therapy program

Interventions

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.

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.
