Brief Summary:
This study will test whether photobiomodulation therapy improves muscle endurance and decreases inflammation in persons with relapsing-remitting multiple sclerosis. We will also investigate mechanisms for any improvements.

Condition or disease Intervention/treatment Phase
Multiple Sclerosis, Relapsing-Remitting Other: Photobiomodulation Therapy Other: Placebo Not Applicable

Detailed Description:
Persons with multiple sclerosis (MS) MS commonly experience muscle weakness and fatigue which may contribute to the commonly reported symptomatic fatigue. Photobiomodulation therapy (PBMT) induced with light in the visible red to near infrared (VIS/NIR) region of the spectrum (600-1000 nm) can stimulate cytochrome c oxidase and improve mitochondrial function. PBMT is an emerging therapeutic modality for soft tissue injury, chronic inflammation, neurodegeneration , and retinal diseases. PBMT has also been used to enhance muscle endurance, strength and recovery in healthy adults. We propose that in persons with MS, PBMT will 1) enhance regional muscle endurance after acute treatment and 2) enhance functional endurance after extended treatment. We will also test to determine if improvements are due to central or peripheral neuromuscular or cardiovascular mechanisms. Final, we will explore if regional PBMT can result in systemic anti-inflammatory effects.

Arm Intervention/treatment
Experimental: Photobiomodulation Therapy
Experimental: Photobiomodulation Therapy comprising 640 nm, 875 nm, and 905 nm light (red lights)
Other: Photobiomodulation Therapy
Photobiomodulation therapy, a mix of red lights thought to improve mitochondrial function will be applied in and acute and chronic manner to test whether muscle fatigue improves in persons with MS.

Placebo Comparator: Control
Placebo device with different wavelengths of light without known physiologic effect.
Other: Placebo
Device with sham light source

Primary Outcome Measures :
  1. Muscle Fatigue [ Time Frame: up to 4 week photobiomodulation intervention, immediately after the intervention, and then 4 months after this extended treatment ]
    Change in muscle fatigue or recovery after photobiomodulation therapy

Secondary Outcome Measures :
  1. Systemic Inflammation [ Time Frame: up to 4 week photobiomodulation intervention, and then again at 4 months post-intervention ]
    Change in pro- and anti-inflammatory cytokines.
