What Causes Proprioceptive Loss?
Proprioceptive loss occurs with cushioned footwear and results in poor position and movement awareness of the foot, ankle-joint, knee-joint and hip-joint.
It is becoming widely accepted that lower extremity joint injuries have arisen from cushioned running shoes, given that habitual shod runners show clear signs of biomechanical impairments (i.e. heel strike).
- Shoe cushioning impairs mechanics because it alters pressure stimuli which causes mechanoreceptors to relay incorrect information from the plantar surface during running.
Moreover, barefoot runners and many minimalist shod runners maintain good proprioception, suggesting that cushioned footwear is the sole cause of proprioceptive loss.
Unfortunately, when a runner suffers a knee or ankle injury, many practitioners recommend increasingly protective footwear, however runners don’t respond well to such prescriptions because more external protection further dismantles proprioception, allowing more maladaptive landing behaviors to manifest during running.
The key to reducing destructive biomechanics is by enhancement of mechanoreceptor activation. Proprioception-based rehabilitation programs improve functional status in these receptors (Beard et al. 1994; Ihara, 1986). Barefoot or pure minimalist running, for example, comprehensively addresses proprioceptive loss by improving the ability to detect lower leg motions.
Because heightened proprioception is strongly associated with the fine-tuning of afferent-efferent arcs, wearing barefoot-like footwear is critical when it comes to preventing lower extremity joint injury in forefoot running.
Proprioceptive Strengthening Exercises
The best way to improve proprioception is to challenge it. For example, one-legged standing balancing exercises while your eyes are closed challenges postural stability (Laskowski et al. 1997). Progressive balancing exercises on a wobble board while barefoot is also highly effective.
The Take Home Message
Running is a neuromuscular function which relies on feedback from peripheral receptors to solidify learned strategies that enable the body to circumvent pain and injury. In a similar vein, your joints may feel mechanically stable, but if your proprioception is compromised, then so is the stability of your movement trajectory when forefoot running.

BSc Neurobiology; MSc Biomechanics candidate, ultra minimalist runner & founder of RunForefoot. I was a heel striker, always injured. I was inspired by the great Tirunesh Dibaba to try forefoot running. Now, I'm injury free. This is why I launched Run Forefoot, to advocate the health & performance benefits of forefoot running and to raise awareness on the dangers of heel striking, because the world needs to know.
