DM #165: Had an attendee at today's course present with this, and it was too good not to share. Total nerd fest coming up. You've been warned.
Yes, pain on one side can cause us to favor the opposite side, but as last night's DM stated, let's not confuse overuse and misuse.
As it relates to today's case, Right hallux (big toe) pain and dysfunction lead to decreased stance time (and push off) on her right foot, and subsequently decreased swing phase of her left leg. This meant that the posterior tissues of her left leg (glutes and hammies) had less time to lengthen (eccentrically contract) and store elastic energy that could be used to extend her left hip during left stance phase. Her body is still going to figure out a way to move forward, and so we begin seeing increased concentric activity of those tissues, and subsequent tendon pain, for her, around her ischial tuberosity.
As my dude @biomechanicaldetective so eloquently states, “A shorter eccentric time to load, but a need to produce the same amount of force equals angry tendons.” So, we see that my attendees butt pain isn't purely a matter of overuse, nor is it going to go away with rest. Misuse makes things unhappy. Check yourself before you wreck yourself.
