Most of us can relate to the occasional ache or pain, especially after performing a task or activity that we wouldn't normally do. Lifting heavy furniture to help a friend move, or starting to train for that 10 km run you have always wanted to participate in are examples of activities that you may not be accustomed to doing on a regular basis. Delayed Onset Muscle Soreness, commonly referred to as "DOMS" is just that....muscular pain and discomfort that occurs up to 24 hours after an unaccustomed physical activity ends. Muscular pain peaks between 24 and 72 hours, and resolves between five and seven days. It is important to note that this type of muscular pain does not occur during the activity itself. People will often report that they did not experience any discomfort during the activity, however, the onset of pain was noted 24 hours or more after the activity was completed.
Symptoms of DOMS may include: pain to the affected muscle, stiffness that may reduce range of motion, swelling, tenderness to touch, and a decrease in muscle strength.
DOMS is common among athletes but can occur in any person that participates in activity at a greater intensity or duration than they would typically participate in. Other examples of activities that can evoke DOMS are: strength training, walking or running down hills, resisted cycling, or high impact activities such as jumping or aerobics. All of these activities require muscles to lengthen while forces are applied, which are referred to as eccentric muscle contractions. To get a clearer picture of the mechanism of injury, think of a person performing a bicep curl with a weight in their hand. As they flex their elbow lifting the weight upward a "concentric contraction" of the biceps muscle occurs. When the weight is lowered, and the elbow extends, the biceps muscle elongates while continuing to contract, creating an "eccentric contraction." It is this eccentric muscle contraction that is responsible for DOMS.
In addition to eccentric muscle contraction, several theories have been proposed to explain the specific mechanism of DOMS including: Muscle spasm, damage to muscle or connective tissue, inflammation, and/or Calcium build up within the injured muscle. Other researchers have further hypothesized that the most probable cause of DOMS may involve the combination of these theories. One suggestion is that eccentric exercise (as described above) may cause damage to the muscle and connective tissue, resulting in tissue inflammation, all of which causes pain post-exercise.
Prevention of DOMs involves slow progression of new exercises, helping muscles to adapt to new forces. In addition, the philosophy "no pain, no gain" does not apply when recovering from DOMS. Pushing through the pain may be detrimental to recovery as painful, weakened muscles may be more at risk for further injury. Treatment of DOMS may include rest, application of ice, physiotherapy modalities such as ultrasound and electrotherapy, massage, and/or compression of the affected muscles.
Please check with your primary health care provider to determine a diagnosis for your muscular pain and the most appropriate treatment plan for your condition.
The Achilles tendon is a tendon at the back of the leg that attaches the calf muscles (gastrocnemius, soleus, and plantaris) to the heel bone (calcaneus), and is considered to be the thickest tendon in the body. It is responsible for plantar flexion of the foot (pointing or pushing off from the toes), and flexion of the knee, which are especially important for walking. Tendinitis refers to inflammation of a muscle, which is most often due to repetitive motions or overuse. Other causes may include a sudden increase in activity, tight calf muscles, or bone spurs (extra bone growth) present where the tendon attaches to the heel bone. Pain and swelling are common symptoms of inflammation, which typically occur at the heel or along the tendon. The tendon may also be visibly red and warm to the touch, and it may be difficult to point or push off from your toes when standing. In addition, people that suffer from Achilles tendinitis will typically experience thickening of the tendon, stiffness in the morning, have an increase in pain following activity or exercise, and limited range of motion of the foot.
There are two types of Achilles tendonitis: Non-insertional Achilles tendinitis and insertional Achilles tendinitis. The non-insertional type affects the muscle fibers of the middle portion of the tendon, while the insertional type affects the muscle fibers that attach to the lower portion of the heel.
In terms of treatment, the concept of “RICE” as discussed in previous columns, applies to this type of injury. Rest, Ice, Compression, and Elevation of the Achilles tendon can be useful to relieve inflammation and pain. Physiotherapy treatment may also be beneficial in order to improve range of motion, strength, and further reduce pain and inflammation. Your physiotherapist may prescribe exercises designed to stretch the calf muscles and improve strength. Research has shown that performing specific eccentric exercises (strengthening while lengthening the muscle) is effective in the treatment of Achilles tendinitis. In addition, orthotics and supportive footwear often help to relieve pain by correcting poor foot mechanics. Please consult with your health care provider to determine which treatment options would be appropriate for you.
De Quervain's tenosynovitis is an inflammatory condition that affects the thumb. More specifically, the condition involves inflammation of the lining of the sheath (synovium) that surrounds two tendons of the thumb: Abductor Pollicis Longus and Extensor Pollicis Brevis. The inflammation prevents the tendons from gliding smoothly through a tunnel located on the thumb side of the wrist. When the synovium of these tendons becomes inflamed friction occurs with certain thumb and wrist movements, which ultimately causes pain and discomfort.
This condition is typically caused by repetitive movements and overuse. It can also be associated with pregnancy and rheumatoid disease. Prevalence of this condition is 0.5% for men and 1.3% for women among adults.
Symptoms of De Quervain's tenosynovitis are pain over the thumb side of the wrist, either gradual or sudden in nature. Grasping, pinching, or gripping objects with the use of the thumb may aggravate the pain. Swelling and inflammation may occur over the base of the thumb at the wrist.
To diagnose this condition the Finkelstein test is often performed. This test involves placing the thumb across the palm and then making a fist with the fingers over the thumb. The wrist is then bent toward the little finger. If pain is reproduced at the thumb side of the wrist, the test is considered to be positive.
Treatment may include the use of a thumb brace or splint, rest, modalities performed by a physiotherapist to reduce pain and inflammation, and specific exercises to improve function. Repetitive thumb and wrist movements should be avoided as much as possible, as well as forceful or painful movements. Please consult with your health care provider to determine the best treatment options for your condition.
Gout is a painful inflammatory condition caused by an increase in uric acid levels that result in the deposit of monosodium urate crystals in specific joints of the body. Uric acid is formed when purines (molecules containing nitrogen) are metabolized (broken down), which then combine with sodium in the body to form urate crystals. When urate levels in the blood reach 6.8 mg/dL there is a greater likelihood of the crystals forming and depositing in specific joints, causing pain, swelling, inflammation, and redness. If left untreated over time, these crystals can form larger lumps called tophi, which can lead to damage of the joint. Symptoms of gout include rapid onset of pain, usually during the night, with pain reaching its maximum within 6 to 12 hours of onset. Typically gout affects the big toe at the metatarsophalangeal joint, however, joints of the foot, ankle, knee, hand, and wrist can also be affected. Initial episodes of gout can be separated by years, but if left untreated episodes may become more frequent.
Gout typically occurs in men more than women, with the average onset being between the ages of 40 and 60. Medical conditions such as obesity, high blood pressure, diabetes, and reduced kidney function are associated with the onset of gout. In addition, medications such as diuretics, anti-hypertensives, and lipid lowering drugs can affect kidney function, and therefore alter the mechanism in which uric acid is broken down.
Diet can also play a role in the onset of gout. Research has shown that foods rich in purines are associated with increases in uric acid levels in the blood. Examples of purine-rich foods include: beef, pork, lamb, veal, organ meats (i.e. liver, heart), tuna, halibut, herring, sardines, shrimp, lobster, scallops, beer, wine, asparagus, cauliflower, beans, lentils, and spinach. Interestingly, consumption of cherries has been linked to lower uric acid levels.
The diagnostic gold standard for gout is joint aspiration, where a needle is inserted into the affected joint to draw out synovial fluid. The fluid is then analyzed for the presence of urate crystals. In addition, blood tests can also be performed to determine the levels of uric acid in the blood, however, elevated levels of uric acid can exist without the presence of any symptoms. Diagnostic imaging, such as CT, MRI, and ultrasound can also be used to determine the if tophi are present in chronic cases of gout.
Your doctor may prescribe certain medications that can help to reduce uric acid levels and inflammation. Certain NSAIDs (nonsteroidal anti-inflammatory drugs) are often prescribed at the onset of the symptoms, however, other medications that also help to reduce uric acid levels and inflammation may also be prescribed. Please consult with your physician to determine which medication(s) would be most effective for your condition. In terms of non-pharmacological treatment, rest, ice, and elevation are often helpful in reducing your symptoms. Your physiotherapist may also use modalities such as ultrasound or laser in the acute phase. Range of motion, strengthening, and/or stretching exercises of the affected joint can be performed between flare ups to maintain function. If your ability to walk is compromised due to pain, your physiotherapist may also recommend a gait aid, such as a cane, to prevent you from developing poor gait patterns. Please consult with your doctor and physiotherapist to determine the best treatment plan for you.
