Laser phototherapy effectively relieves pain, with total energy being the most crucial parameter. Optimizing total energy in laser phototherapy enhances pain relief outcomes.
Area of Science:
- Photomedicine
- Pain Management
- Biophysics
Background:
- Laser phototherapy research for pain relief shows inconsistent outcomes due to varied parameters.
- Existing literature lacks consensus on optimal laser phototherapy settings for pain management.
Purpose of the Study:
- To identify optimal parameter ranges for laser phototherapy in pain relief.
- To analyze aggregated data from primary literature to establish evidence-based parameters.
Main Methods:
- Conducted a meta-analysis of 96 studies meeting inclusion criteria.
- Utilized Cohen's d statistic to determine treatment effect size.
- Identified optimal parameter ranges associated with large effect sizes and validated them using cross-validation.
Main Results:
- Meta-analysis revealed a highly significant average effect size (d = +1.36).
- Total energy emerged as the most impactful parameter, with optimal ranges of 120-162 J and 15.36-20.16 J.
- Cross-validation confirmed the accuracy of optimal total energy ranges at 68.57%.
Conclusions:
- Laser phototherapy is a highly effective modality for pain relief.
- Optimizing total energy is key to maximizing the pain-relieving effects of laser phototherapy.
