Summary
Speech-language pathologists reached expert consensus on using photobiomodulation (PBM) for voice therapy. This agreement helps refine criteria for PBM
Area of Science:
- Voice science and speech-language pathology.
- Biomedical engineering and therapeutic technologies.
Background:
- Photobiomodulation (PBM) is an emerging therapy.
- Its application in voice therapy requires standardized criteria.
Purpose of the Study:
- To establish expert consensus on photobiomodulation (PBM) criteria for voice therapy.
- To guide speech-language pathologists in PBM application.
Main Methods:
- Delphi technique employed with 7 voice specialist speech-language pathologists.
- Two-phase data collection: interviews and a 55-item questionnaire.
- Content Validity Coefficient (CVC) used to assess agreement.
Main Results:
- Consensus achieved on 34 items (CVC ≥ 0.75).
- Overall CVC was excellent (0.78).
- 31 items showed excellent CVC (≥ 0.78).
Conclusions:
- Expert consensus supports photobiomodulation (PBM) in voice habilitation/rehabilitation.
- Findings can enhance PBM prescription and usage criteria.
- Results may inform future research and clinical guidelines.

01:19Overview of Regeneration and Repair
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

01:33Whole Body Regeneration
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential; even...
01:24Muscle Recovery and Fatigue
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective response...
