New Study Shows Benefit of Eccentric Strengthening Exercise for Plantar Fasciitis Treatment

By Larry Huppin, DPM

A 2014 study by Ratcliff demonstrated that doing high load strength training has potential to improve plantar fasciitis symptoms faster than stretching. This is so far the only study on high load training for plantar fasciitis but it is certainly worth considering as another treatment option. High-load training is, however, a standard treatment for conditions such as Achilles tendonitis.

There is some question as to why this treatment is effective for treating plantar fasciitis. The most accepted hypothesis is that the high load exercise acts to break down the tissue a bit leading to a new healing cycle and an increase in production of collagen (the plantar fascia is made up of collagen fibers). For detailed information on all of the most effective treatments for plantar fasciitis visit our Heel Pain / Plantar Fascitiis Treatment Guide.

We have been using high-load strength training as an effective treatment as long as it is used in combination with other treatments for plantar fasciitis. It should not be used as a standalone treatment. For example, these exercises should be used in combination with treatments designed to reduce tension on the plantar fascia such as plantar fasciitis specific orthotics.

High load strengthening should only be used under the direction of a medical professional and should not be used for self-treatment as this type of strengthening can slow healing time in some situations. We do have information on recommended self-treatment suggestions for plantar fasciitis here.

Where Does High Load Training Fit Into Plantar Fasciitis Treatment

When treating plantar fasciitis I follow this protocol:

  • Second, if reduction of force does not lead to rapid pain relief then we institute treatments that facilitate healing. Depending on the patient this might include:
  • Third, move on to using high load therapy to progressively increase the ability of the plantar fascia to handle greater loads.

How to do High Load Training for Plantar Fasciitis

  • Perform one-legged heel raises on a stair with a towel inserted under the toes to elevate the toes (Figure). The towel should be thick enough that your toes are bent up as far as they will go at the top of the heel raise.
  • Perform the exercises every other day for three months.
  • Every heel-rise consists of a three second concentric phase (going up) and a three second eccentric phase (coming down) with a 2 second isometric phase (pause at the top of the exercise).
  •  Start at 12 repetition maximum for three sets.
  • After two weeks, increased the load by using a backpack with books in it and reduce the number of repetitions to 10RM and at the same time increase the number of sets to four.
  • After four weeks, perform 8RM and perform five sets. Keep adding books to the backpack as you become stronger.

We don’t have our patients start progressive high load training until the initial symptoms have resolved.
