Ever feel pain or swelling on the side of your foot? These symptoms may be due to a condition called Cuboid Syndrome, also known as cuboid subluxation or lateral plantar neuritis. In addition to pain in the lateral mid-foot, redness and a restricted range of motion in the ankle may be present. This syndrome is typically associated with an inversion sprain of the ankle. This is when the foot is forced inwards causing the cuboid bone to sublux, or partially dislocate. The cuboid bone is located near the mid-point of the outer side of the foot and is one of the seven tarsal bones that make up the arch of the foot. It connects the foot and ankle as well as provides stability to the foot.
The peroneus longus muscle is a muscle that runs along the outer side of the lower leg and attaches to the lateral side of the foot. Repetitive strain of this muscle due to activities such as ballet, jumping, or running, may place tension on the cuboid bone. Commonly found in athletes, Cuboid Syndrome may also occur in sports such basketball, football, or soccer. Weight-bearing, uneven pavement, or quick changes in direction that occur in sports may aggravate symptoms. A third cause of this syndrome may be an individual’s altered foot biomechanics. Athletes who have over-pronated feet, also known as flat feet, may be more prone to cuboid subluxation.
Imaging such as x-rays, MRIs, and CT scans can be used to rule out other causes of pain. However, a cuboid subluxation can be difficult to diagnose and therefore, must be carefully assessed by a general physician or other health care professional.
Daily strengthening and mobility exercises should be performed on a pain-free basis to prevent the foot and ankle from becoming weak or stiff. Watch the videos below on how to properly perform strengthening exercises:
Other treatment options include foot support such as padding, taping, or orthotics to help stabilize the bones of the midfoot or correct for over-pronation. Rest from repetitive, weight-bearing actions such as jumping or running may help alleviate pain. Ice affected area for 10 minutes at a time to reduce swelling and inflammation. Consult your family physician, physical therapist, or podiatrist to perform a manipulation if the cuboid bone is suspected to be dislocated.
Altitude training involves spending several weeks at a higher altitude (preferably over 2000 m or 8000 ft above sea level) to adapt the body physiologically. At elevations greater than 1200 m or 3950 ft, there is a decrease in atmospheric pressure which reduces the partial pressure of oxygen in inspired air. This causes decreased arterial oxygen levels and leads to increased ventilation and cardiac output, along with an elevation in heart rate. Performance will decrease for individuals that have not acclimatized to the change in pressure and are consequently exposed to a risk of high-altitude illnesses.
Acclimatization is the process of adapting to the decrease in oxygen concentration at a specific altitude. With acclimatization, there will be an increase in heart rate, blood pressure, bicarbonate excretion, respiratory frequency and volume along with a reduction in plasma volume. To compensate for the decreased arterial oxygen levels, erythropoietin (EPO), a hormone in the body, will trigger more red blood cell production to aid in oxygen delivery to the muscles. Training at high altitudes allow athletes to produce additional red blood cells that will provide a greater cardiovascular effect on performance at competitions held at lower elevations.
Acclimatization requires an altitude exposure of more than 1 week. Staged ascents promote gradual and partial acclimatization when an individual resides at a moderate elevation before ascending to a higher elevation to reduce the adverse consequences of rapid ascent. The first stage of ascending should be greater than 3 days at a moderate altitude. Remaining at a moderate altitude for 3 to 7 days will reduce the symptoms and risk of altitude sickness. However, a time period of 6 to 12 days will improve athletic performance.
High-altitude illnesses can occur at elevations above 2500 m. Mild altitude illness can occur between 2000 and 2500 m.
Acute mountain sickness ( is commonly experienced by individuals 6 to 12 hours after ascending to elevations above 2500 m with the prevalence and severity increasing with higher altitudes. Symptoms include: headaches, nausea, dizziness, and sleep disturbance. Some risk factors may be a lack of previous acclimatization, history of migraines, age of 46 and above, or being a female. Symptoms typically resolve within 1 to 2 days with rest or with non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin. If symptoms become severe, descend immediately or use supplemental oxygen.
High-altitude cerebral edema (HACE) is a more severe form of altitude illness. Symptoms include: truncal ataxia (loss of body control), decreased consciousness, mild fever, and coma. If a headache is poorly responding to NSAIDs, then this is an indication of acute mountain sickness progressing to (HACE).
High-altitude pulmonary edema (HAPE) presents with a loss of stamina, dyspnea, dry cough, cyanosis (bluish skin), or pink, frothy sputum (phlegm). The risk of HAPE increases with increased altitude and faster ascents. HAPE occurs when fluid accumulates in the lungs due to rapid altitude ascent or ascent accompanied by strenuous exercise. Untreated HAPE may result in death approximately 50% of the time.
Prevention of high-altitude illnesses involve acclimatization before exposure, slow ascent, and appropriate pharmaceuticals for the corresponding illness. For mild AMS, take a rest day or descend 500 to 1000 m if there is no improvement in symptoms. For severe AMS, descend immediately and use supplemental oxygen at 2 to 4 L per minute. A hyperbaric may also be used for severe AMS. AMS may be treated with NSAIDs or acetazolamine. For severe AMS, use an appropriate dosage of dexamethasone.
Descend immediately if symptoms of HACE or HAPE are experienced. Use supplemental oxygen at 2 to 4 L per minute or a hyperbaric bag. Consider dexamethasone for HACE and nifedipine for HAPE. Consult a physician for more information on which drugs to use.
Preparing for a competition in another country takes weeks in advance to properly adapt the body to new environmental conditions. There are a number of aspects to consider when travelling abroad such as the climate, elevation, pollution, accommodations, food, water, vaccinations, and emergency plans.
Travelling in another country entails eating a wide variety of exotic foods. Avoid risk of food contamination by avoiding tap water with ice, peeled fruits, shellfish, and buffet style meals. Bring a water filter or water purification tablets. It is recommended to eat foods that are similar to the foods you would eat at home. Scout potential restaurants nearby and determine what to items to pack if necessary.
Avoid high-fiber foods before competition and limit fat as well as protein intake prior to activity. Consume carbohydrates such as bread, rice, or pasta prior to competition. Eat a large meal at least 3 to 4 hours before the competition to allow for adequate digestion. A small snack will take approximately 1 hour to be properly digested.
Ensure the coaching staff, medical aids, and/or you yourself are familiar with the medical personnel at the facilities as well as the ambulance and emergency procedures. Apply for the appropriate travel insurance. Remember to pack any required medications and a small first-aid kit. For any acute sprains, immediately rest, apply ice, compress, and elevate the injured part. This is known as the R.I.C.E. method.
For colder environments, wear layers of clothing with the innermost layer being made out of lightweight polyester or polypropylene, the middle layer made out of polyester fleece or wool, and the outer layer as protection from the wind or rain. Use clothing vents and adjust insulation to reduce sweat accumulation. Only wear the outer layer if it is windy or rainy.
For warmer environments, wear breathable, lightweight materials and protect yourself from the sun with proper coverage by wearing a hat, sunglasses, long sleeves or a thin jacket. Bring sunscreen and proper footwear.
Ever wondered whether to use ice or heat for your sore muscles, your healing fracture, or any injury? Both ice and heat have been commonly used to treat an array of injuries, but when to use either one is critical in preventing further damage and promoting faster recovery.
Acute irritation or inflammation of a muscle, ligament, or tendon is typically treated with ice. The cold application reduces inflammation and numbs the pain, especially when the superficial tissues are red, hot, and swollen. The inflammatory response associated with damage to tissues is a defence mechanism in the human body that lasts for the first several days to protect against infection. The response involves immediate changes to blood flow, increased permeability of blood vessels, and flow of white blood cells to the affected site.
Ice can be used for gout flare-ups, headaches, sprains, and strains. It is crucial to apply ice to the site of injury during the first 48 hours post-injury to minimize swelling. For soft tissue injuries such as muscle strains or ligament sprains, an ice massage involving elevation of the injured body part above the heart and circular movement of an ice pack around the affected area may promote faster recovery of these acute injuries. Apply for 10 minutes at a time, then take a break from icing for another 10 minutes. Repeat this process 3 to 5 times a day. Remember to wrap the ice pack in a dry cloth or towel.
Heat can also be used for headaches, sprains, and strains as well as arthritis or tendinosis. Heat causes blood vessels to dilate which increases blood flow and relaxes tight or stiff muscles and joints. Do not use heat during the initial inflammatory response as this will further aggravate the site of injury. For minor injuries, applying heat for 15 to 20 minutes at a time may be sufficient to relieve tension. However, longer periods of heat application such as 30 minutes to an hour may be required for major chronic injuries. Hot baths, steamed towels, or moist heating packs can be used as different heat options.
Recent research has shown that nearly 40% of 7 to 18 year old baseball players endure elbow and shoulder pain during their baseball season. Nearly half of these injured players report their ongoing participation despite having pain. A recent epidemiological study of ulnar collateral ligament (UCL) injuries in athletes 17 to 20 years old reported the number of UCL reconstructions has increased dramatically for this age group. Early education and detection of elbow injuries in throwing sports may help reduce the number of overuse injuries from developing.
“Little league elbow,” or known as medial epicondyle apophysitis, is most commonly found in young throwers. Sports such as baseball, softball, tennis, or golf, can result in this overuse injury to the growth plate on the inside of the elbow. Repeated stress to the growth plates may cause inflammation and lead to pain or swelling. Serious injury may even result in separation of the growth plate from the rest of the bone. Players may also experience a reduced range of motion and a decreased ability to throw hard or far. A child experiencing any symptoms involving their arm should cease activity and see a pediatric specialist or their family physician. X-rays may be required to determine the extent of damage.
Prevention begins with identifying causative factors early in the season and adhering to strict guidelines such as the pitch count for young players and the duration of participation in a given year. Total body conditioning that involves strengthening the hip, back, and legs may help reduce the strain on the athlete’s arms. See below for exercises on how to stretch and strengthen the forearm.
Acute sprains and strains may impede performance and delay return to a sport. Proper management, treatment, and prevention is essential to recovering effectively. An athlete must first understand the definition and recognize the differences between a “sprain” and a “strain.” A sprain is defined as a violent overstretching of one or more ligaments in a joint. A sprain can result in pain, tenderness, swelling or bruising at the joint. A strain is defined as a stress or direct injury to the muscle or tendon. A strain may also cause pain when moving or stretching the injured muscle, but can also cause muscle spasms.
1) Grade I – Mild Strain: slightly pulled muscle with no muscle or tendon tears and no loss of strength and low levels of pain
2) Grade II – Moderate Strain: partial tearing of the muscle or tendon at the bone attachment with reduced strength, moderate pain levels
3) Grade III – Severe Strain: complete rupture of muscle-tendon-bone attachment with separation, substantial loss in strength and high levels of pain
1) Grade I – Mild Sprain: minor tearing of some ligament, no loss of function
2) Grade II – Moderate Sprain: partial rupture of portion of ligament, moderate loss of function
3) Grade III – Severe Sprain: complete rupture of ligament or separation of ligament from bone, substantial loss of function
2) ICE: Sudden cold may help constrict capillaries and blood vessels to slow or restrict internal bleeding. Place an ice pack between a towel or dry cloth. Apply ice every hour for 10 to 20 minutes at a time.
3) COMPRESS: Compression can help reduce swelling post-injury. Wrap the injured part firmly with an elasticized bandage, compression sleeve, or a cloth. Do NOT wrap the cloth too tightly as it may cut off blood circulation and lead to more swelling.
4) ELEVATE: Elevate the injured part about level of the heart to reduce swelling and pain. Place a soft object such as a pillow or piece of clothing to use as a prop below the body part.
Continue to follow the above RICE method for two to three days post-injury. Daily stretching may help loosen the muscle. Key to prevention is to stretch the tight muscles and strengthen the weak muscles.
Watch the videos below on how to recover from a common ankle sprain or shoulder strain:
A catastrophic cervical spinal cord injury occurs with structural distortion of the cervical spinal column due to actual or potential damage to the spinal cord. Damage above the C5 vertebrae in the spinal column results in the greatest risk of immediate sudden death for an athlete. Above this level, damage may impair the spinal cord’s ability to transmit respiratory or circulatory control from the brain. Effective acute care is critical in preventing permanent dysfunction or death in an athlete as a biochemical cascade of events can occur during the initial 24 to 72 hours post-injury.
|Common symptoms include: visible wounds, fractures, swelling, facial bruising, altered state of consciousness, bleeding, stiff neck|
