DOI: https://doi.org/10.56984/8ZG20A8mY

Abstract

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 flexor tendon laceration.
Material and methods. Thirty male patients between the ages of 20 and 40 who underwent unilateral zone II flexor 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 significant decrease in the VSS and a significant 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 significantly lower VSS and a significantly higher TAM (p < 0.01).
Conclusion. Early applications of LLLT post surgical repair of flexor tendon improve TAM and minimize scar formation.

Abstract
Introduction. Postnatal Pelvic girdle pain (PGP) is common complaint in women all over the world and it has a major impact on health and functioning as it decreases quality of life. The start of PGP is typically by weeks 17–19 of gestation, with a peak of occurrence by weeks 24–36 postpartum continuation. Studies have shown that 5–27% of the women had persisting pain 1–3 months after delivery. Methods. Ninety postnatal women’s was randomly classified into three groups, Group (A): Contains of 30 women’s treated with pelvic stabilization exercises. Group (B): Contains of 30 women’s treated with low-level laser therapy only and group (C): Contains of 30 women’s treated with pelvic stabilization exercises and low-level laser therapy all groups remain twelve sessions over six week’s period by two sessions per week. Visual analogue scale, serum cortisol level, pelvic girdle questionnaire, Faber test and P4 test were measured and compared at 0 and 6 weeks after the treatment in the three groups. Results. All groups improved significantly from pretests to posttests score on both outcome measures of VAS, PGQ, cortisol level, Faber test and P4 test p = 0001. These data support the findings that when patients are unable to exercise, low level laser therapy is an appropriate alternative for pain reduction and increased daily function for individuals suffering from postpartum pelvic girdle pain. Conclusion. Our Results revealed that laser therapy accompanied with pelvic Stabilisation exercise is effective in improving postpartum pelvic girdle pain reducing, pain stress, decrease disability and improve activity of daily level.

Abstract
Background. The Distal end of radius fracture is the most common fracture site in the upper extremity; it causes functional problems and can result in some disabling complications. Objective. The purpose of this study was to investigate the effect of Low-level laser therapy versus therapeutic ultrasound after the distal end of radius fracture fixation. Method. Forty patients were assigned randomly into two groups (Group A and Group B) with ages ranged from 18-45 ys. Group A consisted of fifteen female patients and five male patients, and received Low-level laser therapy, group B consisted of fifteen female patients and five male patients, and therapeutic ultrasound for 3 times per week for 4 weeks. Patients were evaluated pre and post-treatment for the function of the wrist joint, grip strength, and wrist joint’s ROM. Results. When comparing patients in group (A) who received LASER therapy, and patients in group B who received Therapeutic ultrasound, we observed clinical difference but it was only statistically significant in favor of group (A) patients in terms of wrist extension, Radial deviation and Ulnar deviation but it was no statistically significant in favor of group (A) patients in terms of wrist flexion. Group (A) patients also had no statistical significance when assessing the wrist proprioception at 20° angle flexion and extension. Conclusion. It can be concluded that both Low-level laser therapy and therapeutic ultrasound after Distal end of radius fractures fixation improved wrist range of motion and proprioception. Both of similar degrees of improvement, however low-level laser therapy had more improvements than therapeutic ultrasound in the wrist ROM of extension, radial deviation, and ulnar deviation.

Abstract

Background. Although various rehabilitation methods have been used to enable patients to return to their normal activities after carpal tunnel release (CTR) such as low level laser therapy (LLLT) and median nerve mobilization, up till now, there is no evidence for the comparison of effects of these two techniques in patients with CTR. Purpose. To investigate and compare the effectiveness of LLLT and median nerve mobilization after CTR on the electrophysiological parameters of median nerve, pain, hand grip and pinch strength. Methods. Forty-five patients of both sexes with unilateral CTR participated in the study. They were randomly assigned into three equal groups. Group I received LLLT and group II received median nerve mobilization three sessions per week for five successive weeks. Group III was the control group. Electrophysiological parameters of the median nerve, visual analogue scale (VAS), hand grip and pinch strength were assessed pre, post-treatment and after three months (follow-up). Results. There was no significant difference between GI and GII in all variables at post-treatment and follow-up. However, there was significant difference in all variables at post-treatment in GI and GII as compared to GIII. At follow-up for all variables, there was no significant difference between GI and GIII (except for pain) with significant difference between GII and GIII. Conclusion. Both of neural mobilization and LLLT lead to better improvement in the electrophysiological parameters of the median nerve, pain and hand function after CTR (in favor of neural mobilization group). Also, median nerve mobilization is more effective on improving hand function than LLLT at follow-up.

Abstract

Background. Burns are one of the most common injuries in pediatric population, gram-positive bacteria is the main pathogens responsible for wound infection that is the leading cause of morbidity and sometimes mortality in growing children with burn. Low level laser is a new treatment option that is increasingly used in the field of wound healing. Aim. To investigate the effect of He-Ne laser on gram-positive bacteria and healing time of deep second-degree pediatric burn. Methods. Thirty children of both genders aged from 2 to 9 years old with 2nd degree upper limb burn infected with gram-positive bacteria participated in this study. They were randomly assigned into two equal groups; either the control group (group A) received systematic antibiotic and 10 minutes’ placebo laser light, or the laser group (group B) received 632 nm laser light, 6 J/cm2 scanning technique for 10 minutes. All patients received regular wound care (dressing). The study protocol was once a day, 3 times / week for one month. Pre and post-treatment evaluation of wound culture and the healing time was recorded for both groups. Results. Wound culture of all children in both groups were negative after two weeks of the study and wound healing time was significantly shorter in the laser group (14.6±5.7 days) than the control group (27±7.3 days). Conclusion. He-Ne laser is an effective option of treatment for 2nd-degree pediatric burn as it has a bactericidal effect on gram-positive bacteria and accelerates wound healing process significantly.
