Acute Effects Of Photobiomodulation Therapy On Muscle Force Recovery In Persons With Multiple Sclerosis: 337 Board #153 May 27 10:30 AM - 12:00 PM
... The maximal voluntary contractions (MVC) recovery test, used in two studies, was used to assess muscle strength. 14,15 The modified fatigue impact scale (MFIS) was used to measure muscle fatigue. 16 ...
... The therapeutic exercise procedure was carried out in circuit stations, with feet together on different surfaces (hard, foam and carpets), sensory stimuli (eyes open and closed), walking forwards and backwards, walking through obstacles and squats, as well as cognitive tasks such as naming objects (1 session per week after PBM for 12 weeks). In the data presented by Rouhani et al. 15 the subjects were divided into EG with PBMT on the muscle belly of the tibialis anterior, 40 J, 80 J, 120 J. 640 nm, 875 nm and 950 nm (4 sessions a week for 4 weeks). And the PG with application of PBMT with a single pulsed wavelength at 640 nm (4 sessions a week for 4 weeks). ...
... Regarding the randomization process, two studies presented a low risk of bias 14,15 and one an uncertain risk (16). Regarding the other domains: deviations from the planned interventions, lack of data in the results, measurement of the results and selection of the studies reported, the three studies included in this review [14][15][16] presented a low risk of bias. ...
Background: Photobiomodulation plays an important role in modulating the inflammatory process, accelerating tissue repair, which can be beneficial in cases such as multiple sclerosis. Objective: To carry out a literature review about effectiveness of photobiomodulation on muscle strength and fatigue in multiple sclerosis. Methods: The databases included were PubMed, Embase, Cochrane, Web of Science, Scopus and LILACS (Latin American and Caribbean Health Sciences Literature). Also the gray literature: Google Scholar, LIVIVO (ZB MED Search Portal for Life Sciences), Open Grey and Library of Thesis and Dissertations CAPES (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior). The risk of bias was assessed using the Cochrane tool, Rob 2, and the data was extracted and assessed by blinded reviewers. Results: Initially 7302 records were found, 7102 in the main databases and 200 in the gray literature. After removing duplicates, 4217 studies were left for Phase 1 and 10 for Phase 2. Finally, 3 randomized clinical trials were included in this review. Conclusion: The studies included risk of bias in this review was predominantly low. PBM proved to be effective in improving muscle strength, but not fatigue. However, the number of human clinical trials is still too few for a more conclusive analysis.
... The Individualized optimal dose of energy was determined based on the preliminary results (e.g. 40J, 80J or 120 J).6 • Placebo: Single pulsed wavelength at 640 nm. ...
