Resisted hip flexion: Stand facing away from a door. Tie a loop in one end of a piece of elastic tubing and put it around the ankle on your injured side. Tie a knot in the other end of the tubing and shut the knot in the door near the floor. Tighten the front of your thigh muscle and bring the leg with the tubing forward, keeping your leg straight. Return to the starting position. Do 2 sets of 15.

Cauda equina syndrome can be causes by spinal birth defects in children or, in adults, falls, inflammation, malignant tumors, injuries, or, and this is the most prevalent cause—a ruptured disc in the lumbar region of the spine. Symptoms of cauda equina include radiating pain in the lower back, pain and numbness in the legs and lower back, weakness in the lower body, loss of sexual function, and loss of bladder control. Another prominent symptom is upper leg pain, sharp pain in the thigh, loss of sensation in the upper leg muscles, and inner thigh pain. It is critical to seek immediate medical care and often including a neurosurgery consultation,

The sciatic nerve is the largest and longest nerve in the body. It arises from the spinal cord as a collection of fibers from the lower vertebrae. This nerve is responsible for the sensation of the skin of the foot and entire lower leg except for a small area on the inner side. It also supplies muscles in the anterior, lateral and posterior compartments of the leg.

Premkumar et al present evidence that the traditional “red flags” for ominous causes of back pain can be quite misleading. The correlation between red flags and ominous diagnoses is poor, and prone to producing false negatives: that is, no red flags even when there is something more serious than unexplained pain going on. In a survey of almost 10,000 patients “the absence of red flag responses did not meaningfully decrease the likelihood of a red flag diagnosis.“ This is not even remotely a surprise to anyone who paid attention in back pain school, but it’s good to have some harder data on it.

Good points on isolating the single joint hip flexors and avoiding compensations. I am curious about your perspective (and others) on why this is less likely to stress the anterior capsule? I tend to add trunk side ending before finalizing the stretch to bias the psoas. The stretch you have outlined seems like an iliacus and ant. capsule biased stretch. Thoughts? If I really want to protect the anterior capsule, I’ll also add a slight amount of hip internal rotation.

Enthoven WT, Geuze J, Scheele J, et al. Prevalence and "Red Flags" Regarding Specified Causes of Back Pain in Older Adults Presenting in General Practice. Phys Ther. 2016 Mar;96(3):305–12. PubMed #26183589. How many cases of back pain in older adults have a serious underlying cause? Only about 6% … but 5% of those are fractures (which are serious, but they aren’t cancer either). The 1% is divided amongst all other serious causes. In this study of 669 patients, a vertebral fracture was found in 33 of them, and the chances of this diagnosis was higher in older patients with more intense pain in the upper back, and (duh) trauma.

You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
