First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two leg exercises—clamshell and frog pump—in 92 sales workers with IT band syndrome, a common cause of knee and hip pain. Participants did one of the exercises plus standard care (heat and TENS) for 12 weeks. Researchers measured pain, range of motion, and daily function to see which exercise worked better.
