Plantar fasciitis is an inflammation of the plantar fascia, a broad, flat ligament in the bottom of the foot that extends from the heel all the way through the great toe.
When this structure becomes overstretched it can tear, and these microtears can cause significant amounts of inflammation in the heel. This inflammation in the heel area is called plantar fasciitis.
Plantar fasciitis is a rather common occurrence in those of us who also concurrently have high arches and also those who have flat feet, as any extreme of foot motion can lead to increased inflammation due to too much force or too much movement in this area.
For those with high arches the plantar fascia is generally tight and restricted and is torn via the repetitive strain of impact, concrete floors and the like.
Those with flat feet have excessive motion of the medial longitudinal arch (inside of foot) and this excess motion tears the plantar fascia just as readily.
Treatment of plantar fasciitis consists of anti-inflammatories, anti-inflammatory modalities such as US, iontophoresis and ice, as well as my personal favorite—rolling a frozen water bottle on the sole of the foot.
A night splint is sometimes useful for plantar fasciitis as it prevents the plantar fascia from contracting and re-tearing in the first few steps of the morning.
A night splint pulls the ankle into dorsiflexion (upwards) and prevents this tightening from occurring.
In many cases of plantar fasciitis, the pain is felt most severely the first few steps in the morning. That is because when the plantar fascia is allowed to heal at night, it will ultimately return and will hurt again in the first few steps of the morning.
If we can put shoes by the side of the bed, we can prevent the plantar fascia from being re-torn in the morning and thus facilitate healing.
Another very useful tool in the treatment of plantar fasciitis is low dye strapping.
This type of taping decreases the force on the plantar fascia and allows it to heal.
Trigger point dry needling is also extremely effective as are custom or non-custom foot orthotics (arch supports that prevent and decrease the repetitive stretching and tearing of the plantar fascia.)
Steroid injections are often extremely effective in the treatment of plantar fasciitis as well and can facilitate healing.
As you can see, there are several types of plantar fasciitis for several types of feet and also specific types of treatment that can be useful.
A consultation with a foot specialist is always a good starting place. For more information on plantar fasciitis, or care and treatment, please feel free to contact the clinic for a no cost consultation.

According to a survey by the Center for Disease Control and Prevention, 30% of adults reported some type of joint pain during the last 30 days. Knee pain ranked as primary joint of complaint for this particular survey1.
In the world of rehabilitation, scientific literature has been pointing to the muscles of the hip as a major player in knee pain2. Strengthening the Hip Abductors (Gluteus Medius) and the Hip External Rotators have been specifically highlighted as a source of pain relief for the knee3, 4. This stands to good reason when analyzing the functional mechanics of the knee; the orientation of the knee is controlled by the position of the femoral head. The position of the femoral head is controlled by the muscles of the hip. In other words, the hip dictates the orientation of the knee in space, and thus, acts as the guide-wire for the muscles of the knee. A good directional pull from the muscles of the knee encourages good movement at the knee joint itself. Good movement decreases stress forces which then can decrease wear and tear, and, ultimately offers pain relief.
To address knee pain by strengthening the hip, kettlebells can be used as a functional therapeutic exercise. Here are a couple kettlebell exercises which can target the muscles of the hip:
High Knees Video
The Hip Abductors are responsible for maintaining pelvic motion and femoral alignment during function. The High Knees are a great exercise for the Hip Abductors because it combines strengthening with balance. In this exercise, the lifting leg is the extremity which applies force. The stance limb is the side which is being strengthened. This exercise is performed by raising a kettlebell up by the foot until the knee of the lifting limb is at the height of hip – a “high knee”. By lifting up the kettlebell using dorsiflexion and hip flexion, a sudden downward force is created on the side opposite to the stance limb. This force then requires the hip muscles of the stance limb to engage and prevent a sudden drop in pelvic height on the lifting side. There are a couple compensatory movements to watch for including excessive leaning, lateral shifting, and forward flexion of the spine. The forward flexion of the spine is caused because when lifting the kettlebell with the “high knee” technique, the lifting extremity utilizes the hip flexors which are connected to the lumbar spine. If one does not control posture and engage the muscles of the stance limb, then the body will want to flex forward. If there is trouble with leaning or weight shifting, then a lighter weight should be used.
Side Swings Video
Resisting the motion of hip abduction and external rotation requires that a force is applied which encourages femoral internal rotation and adduction. One of the best exercises to apply this force and thus strengthen the muscles of the hip for knee pain is the Side Swing. By swinging the kettlebell on the side of the body, more weight is pulled over the lower extremity (and hip) you wish to strengthen. This same pull will also attempt to bring the knee and femur into a position of adduction and internal rotation. By side swinging in correct mechanics, we then resist the unwanted motion of hip internal rotation/adduction and therefore will strengthen the hip abductors and external rotators.
The Single Leg Deadlift: Golfer’s Lift Variation
Single Let Deadlift Video
This version of the Golfer’s Lift is a variation of the Single Leg Deadlift. The purpose of this exercise is to focus strengthening at the hip while limiting motion at the knee. Once again, we find ourselves in an exercise where the stance limb is the limb which is being strengthened. By moving into the combination of a deadlift and mini-lunge, the hip abductor must be activated to prevent changes in the horizontal position of the pelvis. By holding the kettlebell on the opposite side of the stance limb, additional muscle recruitment is forced upon the hip abductors. This exercise also requires that the individual is in good control of knee position; avoiding adduction and internal rotation is of key importance. Additionally, maintaining the single leg stance is an added challenge for control and balance. Do your best to limit the contact of the trailing limb. Finally, spinal posture must be preserved for safety during this exercise.
In the address of knee pain, training and strengthening the body in functional movement is always a desireable plus. Many of my patients and clients who used kettlebells for therapeutic exercise consistently remarked that the areas of complaint always felt better after kettlebell exercise. Despite the repetitive squatting motions of most swing based exercises in kettlebells, the population I encounter who most consistently express that their symptoms improve after a session with kettlebells are those who have knee problems. When the call for treating knee pain with exercise is made, I hope that kettlebells will be one of the therapies that will answer the call.
