COMPARISON STUY OF KINESIOTAPE AND LOW-LEVEL LASER THERAPY ON HYPERTROPHIC SCAR

COMPARISON STUY OF KINESIOTAPE AND LOW-LEVEL LASER THERAPY ON HYPERTROPHIC SCAR

Hypertrophic scars after burn injury often cause pain, stiffness, and cosmetic concerns. Kinesio taping (KT) and low-level laser therapy (LLLT; photobiomodulation) are widely used, yet direct comparisons and combined-therapy data remain limited. This single-center, three-arm, parallel randomized controlled trial will compare KT alone, LLLT alone, and their combination in patients with post-burn hypertrophic scars. Sixty participants will be randomized (1:1:1) to receive KT (reapplied every 2-3 days), LLLT using a 905-nm pulsed device (three sessions per week), or KT+LLLT for 8 weeks; all groups receive standardized scar care. Outcome assessors will be blinded. The primary outcome is change in scar pliability/firmness measured with a modified Schiotz tonometer from baseline to week 8. Secondary outcomes include change in pain intensity on a 10-cm visual analogue scale and treatment-related adverse events; an optional assessment at week 12 will evaluate durability. We hypothesize that KT+LLLT will produce greater improvements in elasticity and pain than either modality alone. The trial will be conducted at the Faculty of Physical Therapy, Cairo University (Giza, Egypt). Sponsor: Cairo University; Collaborators: National Institute of Laser Enhanced Sciences (NILES) and Faculty of Physical Therapy.

Objective: Compare the effects of kinesio taping (KT), low-level laser therapy (LLLT), and their combination on pliability and pain of post-burn hypertrophic scars.

Design: Single-center, three-arm, parallel randomized controlled trial (1:1:1); assessor- and analyst-blinded.

Setting: Outpatient clinic, Faculty of Physical Therapy, Cairo University (Giza, Egypt).

Participants: ~60 patients with clinically diagnosed hypertrophic scars after burns; able to complete 8-week treatment; standard exclusions for open wounds, infection, photosensitivity, etc.

Interventions:

Arm A: KT + standardized scar care (tape reapplied every 2-3 days).

Arm B: LLLT (905-nm pulsed device; ~16.2 J/cm²; 3×/week).

Arm C: KT + LLLT on the same schedule.

Duration: 8-week treatment; optional week-12 follow-up for durability.

Primary Outcome: Change in scar pliability/firmness (modified Schiotz tonometer) from baseline to week 8.

Secondary Outcomes: Change in pain (10-cm VAS); treatment-related adverse events; optional week-12 persistence.

Randomization/Concealment: Computer-generated sequence; SNOSE envelopes.

Analysis: Intention-to-treat; linear mixed-effects models with adjusted pairwise contrasts (Holm/Bonferroni).

Sponsor: Cairo University. Collaborators: National Institute of Laser Enhanced Sciences (NILES) and Faculty of Physical Therapy, Cairo University.

Hypothesis: KT+LLLT will yield greater improvements than either modality alone.

Exclusion Criteria:

• Open wounds or ulceration at or near the scarred area. Systemic medical conditions such as uncontrolled diabetes mellitus, cardiovascular disease, or a history of skin malignancy in the treatment region. Diagnosed deep vein thrombosis (DVT).Non-adherence, unwillingness to participate, or inability to follow the protocol. Cognitive impairment, psychiatric illness, or communication barriers affecting informed consent or participation.
