Persistent knee and lower back pain among office workers is often misdiagnosed as a muscle tension issue, but fitness coach Dan Go suggests the root cause frequently lies in restricted ankle dorsiflexion. According to Go, prolonged sitting causes the ankle joint to lose its range of motion, triggering a biomechanical chain reaction that forces the hips, knees, and lumbar spine to compensate for the stiffened joint.
The Biomechanics of Stiff Ankles
Dorsiflexion is the movement of the foot pulling upward toward the shin. When this range is limited due to hours of sedentary desk work, the body undergoes a series of compensations during basic movements like squatting or bending. As detailed by Go on X (formerly Twitter) on August 14, these compensations include heels lifting off the floor, knees caving inward, and the lower back rounding during a squat. These adjustments occur because the ankle is no longer effectively facilitating the movement, forcing the hips and lower back to work beyond their intended capacity.
Did you know?
The body often masks mobility issues by over-relying on more mobile joints. When your ankles lose the ability to flex, your hips and lower back absorb the stress, often leading to the chronic aches commonly blamed on “bad posture.”
The 30-Second Wall Test
To identify if restricted ankle mobility is contributing to lower body pain, Go recommends a simple assessment. Stand facing a wall and place your big toe approximately four inches away from it. Attempt to drive your knee forward until it touches the wall while keeping your heel pinned flat to the floor. If the heel lifts or the knee drifts inward to avoid the wall, it indicates a limitation in dorsiflexion. Testing both legs independently is essential, as mobility often varies between the left and right sides.
Restoring Mobility with Ankle Mobs
Unlike traditional static stretching, which focuses on lengthening muscle tissue, “ankle mobs” aim to restore the joint’s natural gliding motion. To perform this drill, place one foot on a stable surface or the floor near a wall. Drive the knee past the toes as far as possible without allowing the heel to rise, then return to the starting position. Performing six slow repetitions per side helps re-educate the nervous system and reintroduces the joint to its forgotten range of motion.
Pro Tip:
Consistency is more important than intensity. Incorporating these six-rep mobilizations into your daily routine can help offload pressure from your knees and lower back throughout the workday.

Frequently Asked Questions
Why does my heel lift during the wall test?
Can ankle mobility exercises replace professional medical treatment?
No. These exercises are for informational purposes and intended to address minor mobility restrictions. If you suffer from chronic or sharp pain, consult a physician or a licensed physical therapist for a professional diagnosis.
How often should I perform these ankle mobilizations?
Go suggests integrating these drills as part of a daily desk routine. Because they are low-impact, they can be performed regularly to maintain the mobility gained through consistent practice.
