PMID: 32301668 DOI: 10.1089/photob.2019.4757

Objective:
To investigate effect of photobiomodulation (PBM) on nerve regeneration after neurotization with the Oberlin Procedure (ulnar fascicle to motor branch to biceps) to restore elbow flexion in patients with brachial plexus injury.
Materials and methods:
This prospective randomized controlled trial was conducted with 14 patients with high brachial plexus injury who underwent neurotization with the Oberlin Procedure to restore elbow flexion. The patients were randomly allocated to two groups of equal numbers: control group and PBM group. In this study, the PBM used has a wavelength of 808 nm, 50 mW power, continuous mode emission, 4 J/cm2 dosimetry, administered daily for 10 consecutive days, with an interval of 2 days (weekends). The outcome of surgery was assessed after 1, 2, 3, and 6 months. The nonparametric Mann-Whitney U-test and chi-square test were utilized to compare the results between both groups.
Results:
After 3 months postoperatively, more patients in the PBM group had demonstrated signs of reinnervation and the mean muscle power was significantly higher in the PBM group. No adverse effects resulted from the administration of PBM.
Conclusions:
PBM is a treatment modality that can improve nerve regeneration after neurotization with the Oberlin Procedure.

STUDY DESIGN: This is a two-group randomized controlled trial.
INTRODUCTION: Finger stiffness after treatment for metacarpal fractures often occurs due to poor compliance to the conventional rehabilitation programs. Gamification has shown success in improving adherence to and effectiveness of various therapies.
PURPOSE OF THE STUDY: The purpose of this study was to evaluate whether gamification, using cost-effective devices was comparable with conventional physiotherapy in improving hand functions and adherence to rehabilitation in metacarpal fractures.
METHODS: A 2-group randomized controlled trial involving 19 patients was conducted. Participants were randomized to a control (conventional physiotherapy, n = 10) or interventional group (gamification, n = 9). The grips strength and composite finger range of motion were measured at the baseline and each follow-up together with Patient-Rated Wrist and Hand Evaluation scores and compliance.
RESULTS: There were no significant differences on improvements of grip strength (means difference 24.38 vs 20.44, P = .289) and composite finger range of motion (means difference 50.50 vs 51.11, P = .886). However, the gamification group showed better results in Patient-Rated Wrist and Hand Evaluation (mean 0.44 vs 8.45, P = .038) and compliance (P
