This thesis investigated light therapy to discover if this therapeutic modality had any effect on pain and swelling in acute lower extremity sprains and strains of collegiate athletes. The subjects were 18-22 year old male and female collegiate athletes from Cedarville University. The study was a blind study using experimental and sham treatment groups. The researcher used the Dynatron 709 Solaris unit with a superluminous diode cluster probe with wavelengths from 660 nm to 880 nm. The dosage was 10 J/cm² of continuous strength for 1 minute and 40 seconds at each injury site. The conclusion of this study was that light therapy decreased pain in the experimental group although it was not found to be significant. There was no significance in the decrease of swelling. My research found that light therapy is an effective modality for use with acute pain of acute lower extremity sprains and strains.
