Background Severe burns lead to decreased pulmonary function and impaired aerobic capacity for long periods post-injury. Low-level laser therapy is a modality utilized to improve aerobic capacity, enhance exercise performance and increase time until fatigue when utilized before aerobic exercises. Purpose This work aims to determine the impacts of pre-exercise low-level laser therapy on aerobic capacity in burn cases. Participants and Methods Sixty adults burned cases of both sexes, aged from 25 to 40 years, with second-degree healed thermal burns, and the total burned body surface area ranged from 20 to 40% participated in this study after complete wound healing. They were randomly categorized into two groups of equal numbers. The study group received low-level laser therapy before aerobic exercises, three sessions/week for 12 weeks, while the control group performed aerobic exercises three times weekly for 12 weeks. All cases received the routine physical treatment program. Aerobic capacity was assessed for both groups by measuring maximum oxygen consumption and time to exhaustion at baseline and twelve weeks following interventions. Findings There was a statistically significant rise in the mean values of maximum oxygen usage and time to fatigue after 12 weeks of treatment in both groups. However, after comparison, the improvements in the study group were statistically significant than those in the control group with (p < 0.01), (p < 0.05) respectively. Conclusion Low-level laser therapy has a beneficial therapeutic impact on promoting aerobic capacity, improving maximum oxygen consumption, and increasing treadmill time in burned cases when preceding aerobic exercises.

Objective. To evaluate the effect of an early intervention of Low Level Laser Therapy (LLLT) on incisional wound scar formation and range of motion (ROM) of interphalangeal (IP) joints post surgical repair of hand lexor tendon laceration. Material and methods. Thirty male patients between the ages of 20 and 40 who underwent unilateral zone II lexor tendon repair of the hand were assigned randomly into two equal groups in number of 15 patients each group. Group (A) (Laser therapy group) received early LLLT in addition to post surgical medical care while the group (B) (Control group) received only post surgical medical care. The primary outcomes were color, pigmentation, pliability and height of wound scars which was measured by Vancouver Scar Scale (VSS). In addition to Total Active Motion (TAM) of hand's digits which measured by hand goniometer. The assessment was taken after 4 weeks and 12 weeks postoperative. Results. After 12 weeks compared to after 4 weeks in both groups, there was a signi icant decrease in the VSS and a signi icant increase in Total Active Motion (TAM) according to within group comparisons (p < 0.001). When compared to the control group at 4 and 12 weeks, the laser group had a signi icantly lower VSS and a signi icantly higher TAM (p < 0.01). Conclusion. Early applications of LLLT post surgical repair of lexor tendon improve TAM and minimize scar formation.

Ocena wpływu wczesńie wprowadzonej terapii laserowej niskiego poziomu (LLLT) na tworzenie się blizny po ranie pooperacyjnej i zakres ruchu (ROM) stawów międzypaliczkowych (IP) po chirurgicznej naprawie uszkodzenia sćięgna zginacza ręki. Materiał i metody. Trzydziestu pacjentów płci męskiej w wieku od 20 do 40 lat, którzy przeszli jednostronną naprawę sćięgna zginacza ręki w stre ie 2, przydzielono losowo do dwóch równych grup po 15 pacjentów w kazḋej. Grupa (A) (grupa terapii laserowej) była poddawana terapii LLLT oprócz pooperacyjnej opieki medycznej, podczas gdy grupa (B) (grupa kontrolna) otrzymała tylko pooperacyjną opiekę medyczną. Rezultaty dotyczyły głównie koloru, pigmentacji, elastycznosći i wysokosći blizn, które zostały zmierzone za pomocą skali Vancouver Scar Scale (VSS). Ponadto, obliczono Total Active Motion (TAM) dłoni, gdzie pomiarów dokonano za pomocą goniometru ręcznego. Oceny dokonano po 4 tygodniach i 12 tygodniach po operacji. Wyniki. Porównując wyniki po 12 tygodniach i po 4 tygodniach zaobserwowano, zė w obu grupach nastąpił znaczny spadek na skali VSS i znaczny wzrost w zakresie (TAM) (p < 0,001). W porównaniu z grupą kontrolną po 4 i 12 tygodniach, grupa, u której zastosowano terapię laserową miała znacznie lepsze wyniki na skali VSS i znacząco wyzṡzy TAM (p < 0,01) Wniosek. Wczesne zastosowanie terapii LLLT po chirurgicznej naprawie sćięgna zginacza poprawia TAM i minimalizuje powstawanie blizn.

Background. Hypertrophic scar (HTS) formation after burn remains a major issue for burned patients and is considered a huge problem for clinicians because the hypertrophic scar is painful, reddish, elevated, pruritic, and aesthetically unacceptable. Purpose. To study the effect of polarized light therapy (PLT) on post burn HTS. Materials and Methods. Thirty patients complaining of HTS formation after thermal burn with ages ranged from 20 to 40 years shared in this study and were randomly distributed into two matching groups in number (15 patients for each group). Group A (Study group): received 10 min. PLT 3 sessions/week plus silicone gel sheet (SGS) kept for 12 hours/day, medical treatment such as (hydration creams and antihistamine drugs), and routine physical therapy (splinting, massage therapy, stretching exercises, and strengthening exercises) for 2 months. Group B (Control group): received SGS kept for 12 hours/day, medical treatment such as (hydration creams and antihistamine drugs), and routine physical therapy (splinting, massage therapy, stretching exercises, and strengthening exercises) for 2 months. Methods of evaluation included Vancouver scar scale (VSS) to measure four parameters of hypertrophic scar (height, vascularity, pigmentation, and pliability) and photographic method to allow for visual assessment of the scars. Results. Comparison between post-treatment and pre-treatment in the study group showed a significant decrease in height, vascularity, pigmentation, and pliability scores (p > 0.01). There was a significant decrease in height and pliability scores of the study group in comparison with that of the control group (p < 0.01), while there was no significant difference in vascularity and pigmentation between groups (p > 0.05). Conclusion. PLT is an effective, easy to apply, and non-invasive treatment modality in post burn HTS.

Background: A frequent skin condition associated with diabetes called diabetic dermopathy may also be associated with neuropathy. The neurological and dermatologic systems are often linked in the pathophysiology of diabetic itch.Objective: This research evaluated the efficacy of low-level laser therapy (LLLT) and polarized light therapy (PLT) in treating diabetes patients' pruritus and dermopathy. Subjects and Methods: This study included forty patients. They were split randomly into two groups with an equal number of people; Group (A): Received low level laser therapy along with medical care (Using antibiotic creams for all patients) for eight weeks; three sessions per week. While, Group (B): Received polarized light along with medical care (Using antibiotic creams for all patients) for eight weeks; three sessions per week. Before and following the treatment, pruritus was measured. Results: This study found no significant differences of low level laser therapy and polarized light therapy in their favourable effects on diabetic dermopathy and itching (p > 0.05). Conclusion: Both low-level laser therapy and polarised light therapy are secure approaches that effectively treat pruritus and dermopathy.
