Can heat or contrast therapy ease your knee pain? new study finds out

This study looked at whether adding heat therapy or contrast therapy (alternating hot and cold) to a specific exercise program helps people with patellofemoral pain syndrome, a common cause of front knee pain. Forty adults aged 18 to 40 with at least three months of knee pain took part. They received supervised sessions of either heat or contrast therapy along with Otago exercises, and researchers measured changes in pain, swelling, knee movement, and daily function.
