Photobiomodulation to Help Spasticity After Stroke
This trial tests whether matching low-level light therapy can reduce leg muscle tightness in adults who have had a stroke and developed spasticity.
-
Photobiomodulation before NMES to see if it reduces fatigue and muscle damage
This trial tests whether a light-based treatment (photobiomodulation) given before a fatiguing electrical stimulation can lessen fatigue, muscle damage, and discomfort in healthy adults.
-
Red-light helmet therapy for people with dementia with Lewy bodies
This test will see if red-light therapy worn as a helmet can help improve thinking, daily life, and brain activity in people with DLB.
-
Nd:YAG laser to improve gum healing after tooth extraction and ridge preservation
This test tries whether multiple Nd:YAG low-level laser sessions after tooth extraction and alveolar ridge preservation help adults heal faster and have less pain.
