Examining the role of footwear cushion in preventing running injuries

Michael Ryan C. Ped (C)

Webinar : Sept 14-25
Discussion: Sept 28- Oct 2

CEPs: 5 structured

Registration Closed

The prevention of running injuries has been a goal of sports medicine for the past 25 years.1  Various prevention frameworks have been proposed over this time-span with only limited success, leading to simply more questions than pragmatic and safer training approaches for runners.2-4 

Footwear has long been considered an important component to preventing injuries in runners.  For nearly every risk factor for injury there has been a corresponding footwear design to mitigate that risk.  Over-pronation, impact loads, and heel strike pattern have each been addressed through the introduction of stabilizing elements8 (dual-density mid-sole, thermo-plastic shank), shock-absorbing materials9, and minimalist designs10 respectively.  Recently, the addition of another functional element, the stiff forefoot rocker, has shown to reduce stress on selected lower extremity tissues suggesting it may also serve an injury prevention role.11 12

This talk will focus on a research study conducted in 2019 that evaluated the clinical effects of a new protective running footwear design incorporating a new adaptive cushioning mid-sole with stronger forefoot rocker.

“The most debated concept about foot and ankle pathology may be the role of instability of the first ray…”
Corinne Van Beek, MD and Justin Greisberg, MD Mobility of the First Ray:Review Article Foot & Ankle International/Vol. 32, No. 9/September 2011

How does instability of the first ray contribute to the pathomechanics of hallux abductovalgus, hallux rigidus, functional hallux limitus and metatarsalgia?

How much of your current knowledge about the first ray is based upon
accepted dogma rather than good science?

Many myths and misconceptions regarding the mechanics of the first ray exist today and often lead the practitioner to implement treatments that ultimately fail.

Here are common myths about the first ray which will be discussed in this webinar:

  1. Hypermobility of the first ray is a theoretical condition of excessive dorsiflexion motion of the first metatarsal during dynamic gait
  2. Clinical measures of hypermobility of the first ray are commonly performed in a static off-weight bearing condition which will not engage multiple forces which occur during dynamic gait
  3. Static measures of first ray mobility do not predict first ray hypermobility during gait
  4. Stability of the first ray is dependent upon specific anatomic structures located at the first metatarsophalangeal joint (1st MTPJ), providing static or dynamic restraint of motion, or both.
  5. Hallux abductovalgus (HAV) deformity is the only pathology of the human foot which demonstrates excessive dorsal mobility of the first ray with static exam, and this hypermobility reduces or vanishes when the first metatarsal is re-aligned over the sesamoids.
  6. Metatarsus primus elevatus (MPE) is a static radiographic measure which does not predict load bearing capacity of the first metatarsal during gait
  7. Patients with evidence of MPE do not show excessive mobility of the first ray with static exam.
  8. Metatarsus primus elevatus is the result of progressive degenerative arthritis and progressive plantar flexion contracture of the hallux seen in hallux rigidus
  9. Most people demonstrate greater range of motion of dorsiflexion of the 1st MTPJ off weight bearing compared to range of motion weight bearing and during dynamic gait.
  10. Studies of patients with evidence of functional hallux limitus with static examination will show normal extension of the 1st MTPJ during dynamic gait

In this presentation, Dr Doug Richie will uncover these myths and reveal the sound science which can change current strategies to treat common pathologies in the human foot.
