Biomechanics in Podiatry
Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.
Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.
At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.
Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates. They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.
Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.
Diagnosing a Child’s Sprained Ankle

When a child injures an ankle, it is often assumed to be a sprain, which occurs when the ligaments that stabilize the joint are stretched or torn, typically from a sudden twist, roll, or awkward landing. Most ankle sprains involve the foot turning inward, a motion called inversion, and may result from sports, running, or stepping on uneven ground. Symptoms like swelling, bruising, and difficulty bearing weight are common. However, similar symptoms can also indicate other issues, such as a growth plate injury or a fracture, which require different care. Because children’s bones are still developing, it is important not to overlook the possibility of a more serious condition. A podiatrist can assess the injury by examining the foot and ankle, testing movement, and ordering imaging, if needed, to confirm the diagnosis. Early evaluation helps prevent complications like chronic instability or improper healing. If you believe your child has sprained an ankle, it is suggested that you promptly schedule an appointment with a podiatrist for an exam and appropriate treatment.
Ankle sprains are common but need immediate attention. If you need your feet checked, contact Darren Day, DPM from Hawaii. Our doctor can provide the care you need to keep you pain-free and on your feet.
How Does an Ankle Sprain Occur?
Ankle sprains take place when the ligaments in your ankle are torn or stretched beyond their limits. There are multiple ways that the ankle can become injured, including twisting or rolling over onto your ankle, putting undue stress on it, or causing trauma to the ankle itself.
What Are the Symptoms?
- Mild to moderate bruising
- Limited mobility
- Swelling
- Discoloration of the skin (depending on severity)
Preventing a Sprain
- Wearing appropriate shoes for the occasion
- Stretching before exercises and sports
- Knowing your limits
Treatment of a Sprain
Treatment of a sprain depends on the severity. Many times, people are told to rest and remain off their feet completely, while others are given an air cast. If the sprain is very severe, surgery may be required.
If you have suffered an ankle sprain previously, you may want to consider additional support such as a brace and regular exercises to strengthen the ankle.

Ankle Sprains
Ankle sprains occur when ligaments that support the ankle stretch beyond their limits and tear. These types of injuries are very common and can occur in people of all ages. Sprains may range from mild to severe, depending on how much damage is done to the ligaments. If a sprain goes untreated, a more severe sprain may occur which can further damage the ankle. Repeated ankle sprains can lead to chronic ankle pain.
There are some risk factors that can increase your risk of suffering a sprained ankle. Those who participate in sports, walk on uneven surfaces, have a prior ankle injury, are in poor physical condition, or wear improper shoes are more likely to get a sprained ankle.
There are a few symptoms to look out for if you suspect you are suffering from a sprained ankle. Some common symptoms are swelling, bruising, tenderness, and instability of the ankle. In cases where the tearing of the ligaments is severe, there may be a “popping” sound when the strain occurs.
The RICE method is proven to be effective in treating ankle sprains. RICE stands for Rest, Ice, Compression, and Elevation. Rest is important for treatment, especially within the first 24 to 48 hours. You should also ice your sprained ankle for the first 48 hours for 20 minutes at a time. A small piece of cloth should be placed between the ice and the affected area. For the compression step, you should wear a brace that is snug, but not too tight that it cuts off circulation. When choosing a brace, be sure to choose one that is suitable for the type of ankle sprain you have. Lastly, you should elevate your foot above the heart as often as possible.
After you treat a sprain, you should go through rehabilitation to prevent the injury from occurring again. There are three phases to the rehab process. The first phase involves resting, protecting, and reducing the swelling of the injury. The second phase consists of restoring the ankle’s flexibility, range of motion, and strength. The third phase consists of slowly returning to activity and maintenance exercises.
If you suspect you have an ankle sprain, you shouldn’t hesitate to consult with your podiatrist. Your podiatrist will be able to give you a proper diagnosis and a suitable treatment option for your condition.
All About Foot Fractures

A foot fracture can affect any of the 26 bones in the foot, including the toes, metatarsals, sesamoids near the big toe, and the rearfoot bones such as the navicular, talus, and heel bone. These foot fractures often result from twisting injuries, falls, or direct impact against a hard surface. Pain is usually immediate and worsens when placing weight on the foot. A podiatrist typically diagnoses a fracture using an X-ray to identify the location and type of break. In some cases, additional imaging may be required if the fracture is complex or not visible on standard X-rays. Treatment depends on which bone is fractured and the severity of the break. It often involves wearing a splint, cast, or a protective shoe or boot to stabilize the foot. Weight-bearing may be restricted for several weeks while the bone heals. If you have broken a bone in your foot, it is suggested that you make an immediate appointment with a podiatrist for an exam and appropriate treatment options.
A broken foot requires immediate medical attention and treatment. If you need your feet checked, contact Darren Day, DPM from Hawaii. Our doctor can provide the care you need to keep you pain-free and on your feet.
Broken Foot Causes, Symptoms, and Treatment
A broken foot is caused by one of the bones in the foot typically breaking when bended, crushed, or stretched beyond its natural capabilities. Usually the location of the fracture indicates how the break occurred, whether it was through an object, fall, or any other type of injury.
Common Symptoms of Broken Feet:
- Bruising
- Pain
- Redness
- Swelling
- Blue in color
- Numbness
- Cold
- Misshapen
- Cuts
- Deformities
Those that suspect they have a broken foot shoot seek urgent medical attention where a medical professional could diagnose the severity.
Treatment for broken bones varies depending on the cause, severity and location. Some will require the use of splints, casts or crutches while others could even involve surgery to repair the broken bones. Personal care includes the use of ice and keeping the foot stabilized and elevated.

Causes, Symptoms, and Treatment for a Broken Foot
The human foot has 26 different bones, and the foot is divided into three parts: the hindfoot, the midfoot, and the forefoot. Each section of the foot is composed of a different amount of bones. For instance, the forefoot is made up of 19 bones. The midfoot is composed of five smaller bones called the navicular, cuboid, and three cuneiform bones. Lastly, the hindfoot is made up of only the talus and the calcaneus. The feet tend to be vulnerable to slipping and twisting; consequently, fractured bones within the foot are common. When a bone gets crushed, bent, twisted, or stretched it may become broken.
Many foot fractures occur through an accident or trauma. More specifically, common causes for broken feet are car accidents, falls, missteps, or overuse. If you have a broken ankle or foot, you may have one or more of the following symptoms: throbbing pain, swelling, bruising, tenderness, deformities, and difficulty walking.
There are some factors that may put you at a higher risk of developing a broken foot. People who participate in high-impact sports are more likely to develop foot fractures because of the stresses, direct blows, and twisting injuries involved in gameplay. Additionally, those who suddenly increase their activity level are more likely to suffer a stress fracture.
Unfortunately, there are different complications that may arise because of a foot fracture. For instance, arthritis may be caused by fractures that extend into the joints. Bone infections are also possible in open fractures due to the bone being exposed to bacteria. However, there are ways you can help prevent yourself from breaking your foot. One way to avoid fractures is to wear proper footwear. If you plan on going on a run, you should wear running shoes. You should also replace your shoes if you notice that they are becoming worn out. For runners, it is best to replace shoes every 300 to 400 miles.
Treatment for foot fractures usually consists of rest, ice, elevation, and compression (RICE). If you plan on wrapping your foot, try not to wrap it too tightly because doing so may cut off blood supply in the foot. You should also avoid walking on the fractured foot.
If you suspect you have a broken foot, you should see your podiatrist right away. It is important that you have someone bring you to your doctor, since driving with a broken foot can be dangerous. You should especially seek urgent care if you are experiencing numbness, pain, or deformities in your foot.
Podiatrist Support for Runner’s Foot Pain

Foot pain in runners is a common issue often caused by plantar fasciitis, metatarsalgia, and stress fractures. Plantar fasciitis involves inflammation of the tissue along the bottom of the foot, while metatarsalgia refers to pain in the ball of the foot. Stress fractures result from repetitive impact and overuse. Stretching can help ease discomfort, including the seated towel stretch to improve flexibility and rolling a frozen water bottle under the arch to reduce inflammation. Wearing properly fitted running shoes with good support is essential. A podiatrist can evaluate pain, identify the underlying cause, recommend targeted stretches and footwear, and provide treatment to promote healing and prevent further injury for long-term foot health. If you have foot pain from running, it is suggested that you consult this type of doctor who can offer appropriate treatment solutions.
Exercising your feet regularly with the proper foot wear is a great way to prevent injuries. If you have any concerns about your feet, contact Darren Day, DPM of Hawaii. Our doctor will treat your foot and ankle needs.
How to Prevent Running Injuries
Many common running injuries are caused by overuse and overtraining. When the back of the kneecap starts wearing out and starts causing pain in your knee, this is commonly referred to as runner’s knee. Runner’s knee is a decrease in strength in your quadriceps and can occur if you’re not wearing properly fitted or supporting shoes. To prevent runner’s knee, focusing on hip strengthening is a good idea, as well as strengthening your quads to keep the kneecaps aligned.
What Are Some Causes of Running Injuries?
- One cause of a common running injury is called iliotibial band syndrome.
- Plantar fasciitis is also another common injury.
- Stress fractures can occur from overtraining, lack of calcium, or even your running style.
Best Ways to Prevent Running Injuries
- Wear footwear that fits properly and suits your running needs.
- Running shoes are the only protective gear that runners have to safeguard them from injury.
- Make a training schedule. Adding strengthening exercises as well as regular stretching can help keep you strong and limber and can lessen the possibility of injuries.
- Stretching keeps muscles limber; this will help you gain better flexibility.

How to Prevent Running Injuries
Overtraining and overusing the feet are the main causes of common running injuries. A number of these common injuries are caused by overrunning. Runner’s knee is a condition that is characterized by the back of the kneecap beginning to wear away and cause pain in the knee. This frequently occurs due to either a decrease in strength in the quadriceps muscles or ill-fitting shoes that are lacking in proper support for the inside of the forefoot. Strengthening exercises focusing on the quad muscle and sports orthotics are the usual treatments for those suffering from runner’s knee. Prevention of the condition lies in a focus on hip strengthening and quad-strengthening to keep the kneecap aligned. To help learn the best exercise to heal runner’s knee, one can also undergo physical therapy.
One common injury, called iliotibial band syndrome, is often caused by overtraining. This condition occurs when the iliotibial band gets irritated, creating pain and discomfort in the outside knee area. Plantar fasciitis, another common running injury, also occurs as a result of inflammation and irritation. Plantar fasciitis is an inflammation and irritation of the bone in the foot. A large amount of pain is often experienced due to plantar fasciitis. The condition can be caused by a high arch, improper footwear, tight muscles, or flat feet. It can best be avoided by stretching and wearing appropriate footwear that supports the foot.
Another common injury for runners is stress fractures. These injuries occur due to running style, overtraining, or a lack of calcium. Stress fractures most often occur in several locations in runners, including the inner bone of the leg, the thighbone, the bone at the base of the spine and the bones of the toes. Stress fractures are best prevented by wearing proper footwear and by running on flat and hard surfaces; this will absorb some of the shock created during running.
Aside from overtraining, other causes of common running injuries include ill-fitting footwear, a lack of flexibility and strength, and irregular biomechanics. The best way to avoid running injuries is to prevent them from even occurring. Both iliotibial band syndrome and stress fractures are preventable. The first step that should be taken to prevent running injuries is to only wear footwear that fits properly and that is appropriate for whatever activity you are doing. Running shoes are the only protective gear available to runners that can safeguard them from sustaining injuries. Choosing the right pair of shoes is therefore extremely important. While running shoes are an important factor, it is also important to consider other facets of your running routine such as training schedules, flexibility, and strengthening. These elements should be considered and altered according to your running needs to best maximize your run and minimize the possibility of injury. Careful stretching before and after a run should also be considered to help prevent running injuries. Stretching muscles enables greater flexibility and a lesser chance of sustaining injury.
Plantar Fasciitis and Podiatry Care

Plantar fasciitis is caused by inflammation of the plantar fascia, the thick band of tissue that runs along the bottom of the foot and supports the arch. This condition often leads to sharp heel pain, especially with the first steps in the morning or after long periods of rest. Risk factors include prolonged standing, flat feet, high arches, obesity, and wearing footwear that lacks proper support. Symptoms include aching, stiffness, or a burning sensation in the heel. If left untreated, the pain can become chronic and interfere with daily activities. A podiatrist can diagnose plantar fasciitis, provide targeted stretching exercises, and offer custom orthotics or treatments to relieve pain and promote healing. If you have heel pain, it is suggested that you consult a podiatrist who can accurately diagnose and treat the condition.
Plantar fasciitis is a common foot condition that is often caused by a strain injury. If you are experiencing heel pain or symptoms of plantar fasciitis, contact Darren Day, DPM from Hawaii. Our doctor can provide the care you need to keep you pain-free and on your feet.
What Is Plantar Fasciitis?
Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia is a ligament that connects your heel to the front of your foot. When this ligament becomes inflamed, plantar fasciitis is the result. If you have plantar fasciitis you will have a stabbing pain that usually occurs with your first steps in the morning. As the day progresses and you walk around more, this pain will start to disappear, but it will return after long periods of standing or sitting.
What Causes Plantar Fasciitis?
- Excessive running
- Having high arches in your feet
- Other foot issues such as flat feet
- Pregnancy (due to the sudden weight gain)
- Being on your feet very often
There are some risk factors that may make you more likely to develop plantar fasciitis compared to others. The condition most commonly affects adults between the ages of 40 and 60. It also tends to affect people who are obese because the extra pounds result in extra stress being placed on the plantar fascia.
Prevention
- Take good care of your feet – Wear shoes that have good arch support and heel cushioning.
- Maintain a healthy weight
- If you are a runner, alternate running with other sports that won’t cause heel pain
There are a variety of treatment options available for plantar fasciitis along with the pain that accompanies it. Additionally, physical therapy is a very important component in the treatment process. It is important that you meet with your podiatrist to determine which treatment option is best for you.

Plantar Fasciitis
Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia is the thick band of tissue that connects the heel bone to the toes. When this band of connective tissue becomes inflamed, plantar fasciitis occurs. Fortunately, this condition is treatable.
There are several factors that may put you at a greater risk for developing plantar fasciitis. One of the biggest factors is age; plantar fasciitis is common in those between the ages of 40 to 60. People who have jobs that require them to be on their feet are also likely to develop plantar fasciitis. This includes factory workers, teachers, and others who spend a large portion of their day walking around on hard surfaces. Another risk factor is obesity because excess weight can result in extra stress being placed on the plantar fascia.
People with plantar fasciitis often experience a stabbing pain in the heel area. This pain is usually at its worst in the morning, but can also be triggered by periods of standing or sitting. Plantar fasciitis may make it hard to run and walk. It may also make the foot feel stiff and sensitive, which consequently makes walking barefoot difficult.
Treatment for plantar fasciitis depends on the severity of the specific case of the condition. Ice massage applications may be used to reduce pain and inflammation. Physical therapy is often used to treat plantar fasciitis, and this may include stretching exercises. Another treatment option is anti-inflammatory medication, such as ibuprofen.
If you suspect that you have plantar fasciitis, meet with your podiatrist immediately. If left untreated, symptoms may lead to tearing and overstretching of the plantar fascia. The solution is early detection and treatment. Be sure to speak with your podiatrist if you are experiencing heel pain.
