Foot & Ankle Anatomy

The human foot and ankle joint is a strong and complex mechanical structure. Made up of 26 bones, 33 joints and over 100 muscles, ligaments and tendons, they bravely bare our weight and incredible stress with every step we take.

It’s no wonder foot and ankle injuries stemming from overuse, trauma, and other painful conditions of the soft tissue, such as plantar fasciitis and Achilles Tendonitis are all too common. Pain and tightness after injury or post-surgery are also conditions that send millions of people searching for relief.

Tightness and poor alignment of your feet and ankles can spread to imbalance and pain in your knees, hips and lower back. The bottom line is healthy feet and ankles can create a healthier pain-free you.

Imagine having your own FOOT MASSAGE anytime. You, like many others will LOVE the deep tissue massage that AnkleSTONE® provides. The massage ‘roll bar’ is fantastic for gentle or aggressive massage. The rough surface of the stone is ideal for therapeutic and invigorating pressure to stimulate blood flow and tissue. People delight with the rough feel of the stone that resembles a pumice stone for an invigorating rub. And you can have a massaging stretch right now as you work on your computer. Your joints and soft tissue require the orthopedic tool for proper positioning and progressive stretch.

Prevent Injury by Stretching

Increasing the elasticity and flexibility of tendons has been shown to reduce injury. Intense activity like jumping, running and dancing put high loads on tendons. This is especially true for the Achilles tendon which often leads to injury. Regular stretching must be practiced to help avoid these types of injuries. The energy capacity of the lengthened tendons improves normal movement and especially athletic performance. As we navigate the ups and downs of our lives, flexible joints with a full range of motion will certainly minimize your potential for injury. Even when just walking.

It is the biologic nature of soft tissue such as tendons, ligaments, even scar tissue to elongate and restore to full range and pain free status. It’s this ‘plasticity’ of soft tissue that makes therapeutic stretching so effective for restoring range-of-motion and eliminating pain. Stretching improves the elastic properties of muscle-tendon units which improves their stretch tolerance.
More people than ever before are searching for help with foot and ankle pain as the number of injuries grows due to a more active aging population and a greater emphasis on physical activity across all age groups. It’s no surprise the expected growth rate of podiatry is greater than the average for all other occupations through the year 2022.

Even with healthy aging, the forces of weight-bearing including standing at work and walking on hard surfaces day-after-day can result in painful conditions. After all, it’s known that on average, a person will have walked approximately 110,000 miles by his or her 80th birthday. That is calculated based on an average of 7500 steps per day. That’s like walking 5 times around the earth.


Medical Conditions of the Feet and Ankles

Plantar Fasciitis

Affects 10 percent of the population and accounts for about 1 million physician visits each year. The painful condition is especially prevalent in runners and other athletes.

Achilles Tendon Injury

The Achilles tendon is the largest tendon in the body. It is estimated that 230,000 people injure their Achilles tendon each year. The injury often persists as a ‘recurrent’ inflammatory issue.

To avoid musculoskeletal injury, overuse injury and over-demand injury, the tendon must be kept elastic and long. Common symptoms are pain, stiffness and swelling.

As we all want a non-surgical solution, it is fortunate that stretching therapy is an incredibly effective method of treatment. For active people, sudden running and jumping can cause Achilles Tendonitis, as you strain the tendon especially during aggressive physical activity. Maintaining ‘elasticity’ through regular stretching is key to reducing injury.

Common Injury among Athletes – According to the American Academy of Orthopedic Surgeons, 25 percent of athletic injuries are foot and ankle-related.


It is generally understood by doctors and surgeons that surgical procedures introduce additional scar tissue into ‘already damaged’ tissue. This added scar tissue is problematic and requires extensive recovery post-surgery for functional movement.

Stretching, along with necessary rest, helps you repair your range of motion much faster.

Bunion Corrective Surgery (also Osteotomy, arthrodesis) often results in difficulty to push off when walking due to stiff joints or corrective surgical tightening of ligaments and tendons.

Big Toe Restriction and Immobility

Walking requires push off… often the big toe doesn’t bend as it should to allow push off. Typically after surgery. Inflammatory scar tissue is laid down in healing but can result in significant restrictions in joint mobility. Without toe push-off during gait (walking), the foot does not perform as it should. A distorted pattern of walking will disturb the alignment of related joints and tissues. Toe and foot mis-alignment leads to knee pain, hip pain and low back pain due to the Heel Strike. Your heel takes the brunt of the force as you contact the floor with each heel strike (most weight bearing is distributed toward the lateral foot).

Diabetic Foot

Diabetic foot problems are a major health concern and a common cause of expensive hospitalization. Two serious complications of Diabetes are nerve damage (neuropathy) and poor circulation. Their consequences can be severe ranging from hospitalization, antibiotics and even amputation of the toes or foot. PREVENTION of damaging foot problems includes a regimen of daily inspection, general care plus flexibility exercise for added benefits. Improved range of motion can positively affect gait, pressure distribution and risk of foot ulceration.

Ankle Pain and Instability or Loss of Balance

Foot and ankle impairments affect balance and mobility in stroke patients, chemotherapy patients, patients with injury or post-surgery. Strength and range of motion of the foot and ankle have been shown to be related to measures of balance and risk of falling in older adults.

AnkleSTONE® Therapy & Exercise

Your doctor or physical therapist may recommend exercises to restore your foot strength and range of motion after surgery. AnkleSTONE® provides a better way to stretch out tight tissues, to recover from contracture formation with proper positioning, and controlled joint load for progressive recovery at home.

The only options for doctors to recommend have been poor and largely ineffective makeshift home remedies along with socks and plastic devices offering little to no therapeutic value. Plastic Water bottles that collapse and explode are ineffective for the deep tissue needs. Tennis balls under the foot to stretch are useless as they roll away and cause the foot to cramp in attempts to stop the ball from rolling away. Wall stretches are limited to one position and manual stretches of the foot are time consuming and offer limited stretching force. These awkward and unpopular devices do little to restore feet and ankles to their preinjury conditions.

Benefits of AnkleSTONE® Therapy

Speed recovery of your musculoskeletal system and improve mobility of lower extremities. Fractures, sprains, car accidents often involve the lower extremities, resulting in serious need for recovery. The resulting contractures, tight joints and movement restrictions must be overcome for full function and mobility to be restored.

Return to your sport or other activity by being proactive about your foot and ankle recovery. Increased Blood Flow through movement is essential for healing. Many ineffective treatments out there only address the pain and not the underlying condition that is causing the pain.

AnkleSTONE® therapy enables the mechanical stretch necessary to alter the length and flexibility of the tissue to allow for healing and increased range of motion for walking and general mobility. Stretching is made easier with controlled and proper positioning.

Stretching is progressive with the proper joint load to allow progressive recovery.
If you are attending therapy, AnkleSTONE® will help you to gain range of motion, conveniently at home, between therapy visits. And will Speed your recovery by providing extra therapy sessions to augment the recovery. Shorter, controlled and frequent stretches are what will improve the elasticity of the soft tissue. AnkleSTONE® enables you to do just that.

Deep tissue repair is possible with AnkleSTONE® because it benefits the deep as well as the superficial layers of leg muscles and feet.
