"Move Better" Series: Exercises To Improve Lower Extremity Mobility And Stability

Yesterday's “Move Better” post presented the Hurdle Step Test, which assesses the mobility and stability of your hips, knees and ankles.  Performing the Hurdle Step Test requires balance, coordination, and mobility through the joints of the moving and standing leg.  If you tried the Hurdle Step Test and had difficulty performing it due to balance or joint mobility deficits, this post will provide exercises that may help address these issues.

EXERCISES TO IMPROVE BALANCE AND STABILITY

Our joints and tendons contain sensory receptors called proprioceptors that respond to the movement and position of the body.  Proprioceptors communicate information to our brain and muscles and help us maintain or change our body position.  A significant part of our static and dynamic balance relies on this proprioceptive system.  Whether we are standing on one leg, walking on a sandy beach, or backpedaling to guard an opponent on the basketball court, these proprioceptors help us control our movement and balance.  Building our proprioception through balance exercises may help us better control positions of our joints during movements, decrease our fall risk, or improve our sports performance.  

The videos below include beginner balance exercises as well as more advanced dynamic balance exercises: 

EXERCISES TO IMPROVE ANKLE MOBILITY 

Dorsiflexion is a motion that occurs at the ankle and involves the movement of the top part of the foot toward the tibia (shin) bone.  When stepping up onto or over an object (like in the Hurdle Step Test) limitations in ankle dorsiflexion may increase your risk of catching your toes or foot on the object or cause you to compensate with increased movement through the hip or trunk.

EXERCISES TO IMPROVE HIP MOBILITY

Stepping over an object (like in the Hurdle Step Test) also requires adequate hip flexion mobility to raise the femur (thigh bone) high enough to help clear the object.  Impairments in hip flexion mobility may also impact other daily activities, like getting down into a squat or lunging.  Hip flexion mobility may be limited by tightness in musculature around the hip joint or restrictions in the hip joint itself. Exercises to improve hip flexion mobility and provided in the video below:

In summary, the Hurdle Step Test is a quick way to assess mobility and stability in parts of the lower extremities.  Check past “Move Better” content for other ways to improve your balance through dynamic strengthening exercises.

"Move Better" Series: Exercises To Improve Your Dynamic Leg Strength

Yesterday’s “Move Better” post presented the Y Balance Test as a way to test your dynamic balance, strength, and stability while moving in various directions.  The Y balance test is a good functional test to assess hip and knee strength in active individuals and is often used to determine an athlete’s risk of lower extremity injury during sport activities. 

 

Improving your dynamic lower extremity strength and balance can improve your sport performance and decrease your injury risk.  Several studies suggest impaired dynamic balance and hip strength are risk factors for lower extremity injury during activity (1,2).  Weakness in the hip musculature may lead to dynamic lower extremity valgus (the knee moving inward) during single leg squatting, jumping, and landing.  Dynamic lower extremity valgus has been correlated with an increased risk of several knee conditions, including ACL injury and patellofemoral pain. 

 

Hip strength and stability are important components of many athletic activities.  Strong hips are needed to transfer force from the lower body to the upper body in sports such as basketball, soccer, volleyball, football, and throwing in track and field.  Strong hips are also required for quick and powerful changes in direction, cutting, and lateral movements.  Dynamic hip strength and stability also plays an important role in daily activities, including walking with a normal gait pattern, standing on one leg, and ascending and descending stairs.  

 

Exercise to improve hip strength and dynamic balance are provided in the videos below.  The video below includes exercises to improve dynamic hip strength:

The next video includes exercises to improve dynamic balance of the lower extremities:

In summary, focusing on hip strengthening and dynamic balance exercises can improve your performance with sport and daily activities and may decrease your lower extremity injury risk.
