The hip rotators not only rotate the thigh on the pelvis but more functionally rotate the pelvis on the weight bearing fixed thigh. Activities such as swing a golf club, and even just walking require some rotation of the pelvis on the weight bearing leg. While we don't need that much range of motion to walk, activities such as running, dancing, tennis, and many other sports can require more hip rotation.
To test the flexibility of the hip flexors, specifically the iliopsoas, the Thomas' test10 is used. The patient lies supine and flexes one hip, pulling one knee to the chest. If a hip flexion contracture is present, the contralateral straight leg will rise off of the table. The modified Thomas' test (Figure 12.11) may be preferred. With this variation, the patient sits at the end of the examination table with the knees flexed to 90 degrees. Next, one knee is pulled tight to the chest. The patient is instructed to lie down while maintaining the knee against the chest. If a hip flexion contracture is present, the contralateral leg will rise off of the table. If a rectus femoris contracture is present, the contralateral knee will extend.
Lie on your back with your feet flat on the floor and knees bent. Cross your right ankle over your left knee. Keeping your lower back pressed into the floor, pull your left knee in towards the chest by threading your hands between your legs and pulling gently on your left thigh. Think about keeping your right knee open to really stretch your hip. You’ll feel a little extra lovin’ in the outside of your hip with this one! Repeat on the other side.
In addition to these exercises, there are simple things you can do every day to help reduce your risk of hip flexor pain. If you sit at a desk for long periods of time, try to get up and move around every hour or so. Warm up properly before any physical activity, and stretch regularly at the end of each workout. Your hips will thank you for it!
The hip flexors are the group of muscles that allow you to lift your knees toward your chest and bend forward from the hips. What is collectively referred to as the hip flexors is actually a group of muscles that includes the iliopsoas, the thigh muscles (rectus femoris, Sartorius and tensor fasciae latae), and the inner thigh muscles (adductor longus and brevis, pectineus and gracilis).
Widen your knees ever so slowly until you feel a stretch in your inner thighs. Make sure your ankles are in line with your knees, your hips stacked over your knees, and your feet and calves should be grounded and toes pointed out. Relax your shoulders, and if you’re able to, lower down to your forearms. If you have a yoga block, resting your chest on it will help you release your hips.
Following the core strengthening, working on glute activation through various hip extension movements is the big finale. For one, the glutes main function of hip extension is an agonist to the hip flexors, and are also directly involved in low back stability, which means they help to pick up the slack for the core during movements, and helps reduce the impulse on the psoas, therefore reducing the “tightness.”
Get down on floor and bring your feet together in front of you, bending your knees out to the side. Sit down into your hips, while keeping your back tall and core tight, and push your knees down to the ground. You can place your hands on your feet or the floor behind you, whatever you need to keep your back tall. If your hips are really tight, gravity might be painful enough for you, no extra pushing required.
To complete this stretch, take a knee in front of a wall so that the toes of the leg you have raised are pressing against the wall. Place that same hand against the wall. Reach behind you with your other hand and grab your leg that’s sitting on the floor by the ankle, and bend it back towards your body. Hold this position and lunge forward towards the wall to complete the stretch. Hold this stretch for 10 seconds, then repeat on the other side of your body.
Stretching is not only for athletes and yogis. Anyone who wants to improve their flexibility and range of motion should consider performing a few stretches every day. People with sedentary lifestyles, in particular, should stretch daily to help improve their mobility. Sedentary individuals are generally more prone to injuries because their tight muscles aren’t acclimated to sudden or jerky movements.
