Repetitive Strain Injury (RSI): Causes, Symptoms, and Treatment

What Is a Repetitive Strain Injury?

Repetitive strain injury (RSI) is a term that describes a range of conditions caused by overuse or misuse of muscles, tendons, nerves, and joints in the body. RSI can affect various parts of the body, such as the neck, shoulders, wrists, hands, elbows, and knees. Some common examples of RSI are carpal tunnel syndrome, tennis elbow, and trigger finger.

RSI is a common and serious problem that can affect anyone who performs repetitive or strenuous tasks. By understanding what RSI is and how to prevent and treat it, one can protect their health and well-being.

Causes Of Repetitive Strain Injury in the Wrist

The causes of repetitive strain injury (RSI) in the wrist are various factors that put excessive stress or pressure on the wrist joint and the surrounding tissues. Some of the common causes of RSI in the wrist are:

• Repetitive motions: Performing the same or similar movements with the wrist over and over again can cause inflammation and damage to the tendons, muscles, nerves, and ligaments in the wrist. Examples of repetitive motions that can cause RSI in the wrist are typing, clicking a mouse, playing an instrument, knitting, or using a hand tool.
• Forceful exertions: Applying too much force or pressure with the wrist can also lead to RSI in the wrist. Examples of forceful exertions that can cause RSI in the wrist are lifting heavy objects, gripping something tightly, or punching or hitting something.
• Awkward postures: Holding the wrist in an unnatural or uncomfortable position for a prolonged period of time can also cause RSI in the wrist. Examples of awkward postures that can cause RSI in the wrist are bending, twisting, or extending the wrist, or resting the wrist on a hard or sharp edge.
• Vibration: Exposure to vibration from machines or tools can also cause RSI in the wrist. Examples of vibration that can cause RSI in the wrist are using a power drill, a chainsaw, a jackhammer, or a lawn mower.
• Cold temperatures: Working in cold environments can also cause RSI in the wrist. Cold temperatures can reduce blood circulation and increase stiffness and sensitivity in the wrist.

RSI in the wrist can affect people in different professions that involve any of the above-mentioned causes of RSI. Some examples of professions that are at risk of developing RSI in the wrist are:

• Office workers: Office workers who use computers, keyboards, mice, or other devices for long hours can develop RSI in the wrist due to repetitive motions, forceful exertions, and awkward postures. Office workers should take frequent breaks, adjust their workstations, use ergonomic equipment, and do some stretching exercises to prevent RSI in the wrist.
• Musicians: Musicians who play instruments such as piano, guitar, violin, or drums can develop RSI in the wrist due to repetitive motions, forceful exertions, and awkward postures. Musicians should warm up before playing, practice with proper technique, use appropriate equipment, and rest their wrists regularly to prevent RSI in the wrist.
• Construction workers: Construction workers who use tools such as hammers, saws, drills, or wrenches can develop RSI in the wrist due to repetitive motions, forceful exertions, vibration, and cold temperatures. Construction workers should wear gloves, use anti-vibration tools, limit their exposure to vibration and cold, and take breaks to prevent RSI in the wrist.

RSI Symptoms

Repetitive strain injury symptoms in the wrist are the signs and indicators that show that the wrist has been injured or damaged due to overuse or misuse. RSI symptoms in the wrist can vary depending on the type and severity of the injury, but some of the common symptoms are:

• Pain: Pain is one of the most common and noticeable RSI symptoms in the wrist. The pain can be sharp, dull, throbbing, burning, or aching. The pain can be felt in the wrist itself or radiate to the hand, fingers, forearm, or elbow. Wrist pain can be worse when moving, using, or resting the wrist.
• Stiffness: Stiffness is another common RSI symptom in the wrist. The stiffness can make it hard to move or bend the wrist normally. The stiffness can also affect the range of motion and flexibility of the wrist. The stiffness can be more pronounced in the morning or after a period of inactivity.
• Swelling: Swelling is a RSI symptom in the wrist that indicates inflammation or fluid buildup in the wrist joint or surrounding tissues. The swelling can make the wrist look larger, red, or warm. The swelling can also cause pressure and discomfort in the wrist.
• Numbness: Numbness is a RSI symptom in the wrist that occurs when the nerves in the wrist are compressed or irritated. The numbness can make the wrist feel tingling, prickling, or pins and needles sensations. The numbness can also affect the sensation and function of the hand and fingers.
• Weakness: Weakness is a RSI symptom in the wrist that results from muscle fatigue or damage in the wrist. The weakness can make it difficult to grip, hold, or lift objects with the wrist. The weakness can also affect the coordination and dexterity of the hand and fingers.

Some specific types of RSI in the wrist have their own distinctive symptoms. For example:

• Carpal tunnel syndrome: Carpal tunnel syndrome is a type of RSI in the wrist that affects the median nerve that runs through a narrow passage called the carpal tunnel in the wrist. Carpal tunnel syndrome causes numbness, tingling, pain, and weakness in the thumb, index finger, middle finger, and half of the ring finger.
• Tennis elbow: Tennis elbow is a type of RSI in the wrist that affects the tendons that attach the forearm muscles to the outer side of the elbow. Tennis elbow causes pain, tenderness, and inflammation on the outer side of the elbow that can radiate to the wrist and forearm.
• Trigger finger: Trigger finger is a type of RSI in the wrist that affects the tendons that bend the fingers. Trigger finger causes pain, stiffness, and locking of one or more fingers in a bent position that can be released with a snap.

RSI symptoms in the wrist should not be ignored or dismissed as they can worsen over time and lead to chronic problems such as arthritis, nerve damage, or disability. Therefore, it is important to seek medical attention if RSI symptoms persist or interfere with daily activities.

Diagnosis

Repetitive strain injury diagnosis is the process of identifying and confirming the presence and type of RSI in the wrist or other parts of the body. RSI diagnosis is done by healthcare professionals such as doctors, physiotherapists, or occupational therapists. RSI diagnosis can involve the following steps:

• Medical history: The healthcare professional will ask the patient about their symptoms, when and how they started, what activities or factors trigger or worsen them, and how they affect their daily life. The healthcare professional will also ask about the patient's medical history, such as any previous injuries, illnesses, medications, or allergies.
• Physical examination: The healthcare professional will examine the patient's wrist or other affected areas for signs of RSI, such as pain, swelling, stiffness, numbness, tingling, weakness, or reduced function. The healthcare professional will also check the patient's range of motion, strength, reflexes, and sensation in the wrist or other affected areas. The healthcare professional may also perform some specific tests to diagnose certain types of RSI, such as:
  • Phalen's test: The patient bends their wrists and presses the backs of their hands together for about a minute. This test can help diagnose carpal tunnel syndrome by causing numbness or tingling in the fingers.
  • Tinel's sign: The healthcare professional taps on the patient's wrist over the median nerve. This test can help diagnose carpal tunnel syndrome by causing a shock-like sensation in the fingers.
  • Cozen's test: The patient makes a fist and extends their elbow while the healthcare professional presses on the outer side of their elbow. This test can help diagnose tennis elbow by causing pain or tenderness in the elbow.
  • Finkelstein's test: The patient bends their thumb into their palm and wraps their fingers around it. Then they bend their wrist toward their little finger. This test can help diagnose trigger finger by causing pain in the thumb or finger.
  • Imaging tests: The healthcare professional may order some imaging tests to rule out other possible causes of the patient's symptoms or to confirm the diagnosis of RSI. Some of the common imaging tests for RSI are:
    • X-ray: An X-ray uses electromagnetic waves to create images of bones and joints. An X-ray can help detect fractures, arthritis, or other abnormalities in the wrist or other affected areas.
    • Ultrasound: An ultrasound uses sound waves to create images of soft tissues such as muscles, tendons, nerves, and ligaments. An ultrasound can help detect inflammation, swelling, tears, or compression in the wrist or other affected areas.
    • MRI: An MRI uses magnetic fields and radio waves to create detailed images of soft tissues and bones. An MRI can help detect damage, inflammation, or compression in the wrist or other affected areas.

RSI diagnosis is important to determine the cause and extent of the patient's condition and to plan the appropriate treatment and prevention strategies. RSI diagnosis can also help avoid complications such as chronic pain, nerve damage, or disability. Therefore, it is advisable to consult a healthcare professional if one experiences persistent or severe RSI symptoms in the wrist or other parts of the body.

Repetitive Strain Injury Treatments

Repetitive strain injury treatments in the wrist are the methods and strategies that can help relieve the symptoms, heal the injury, and prevent further damage to the wrist or other parts of the body. RSI wrist treatment can vary depending on the type and severity of the condition, but some of the common treatments are:

• Medication: Medication is a RSI wrist treatment that can help reduce pain, inflammation, and swelling in the wrist. Some of the common medications for RSI wrist treatment are:
  • Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs are drugs that can help lower inflammation and pain in the wrist. Some examples of NSAIDs are ibuprofen, naproxen, or aspirin.
  • Analgesics: Analgesics are drugs that can help relieve pain in the wrist. Some examples of analgesics are acetaminophen, codeine, or tramadol.
  • Corticosteroids: Corticosteroids are drugs that can help reduce inflammation and pain in the wrist. They can be taken orally or injected into the wrist joint or surrounding tissues.
• Physiotherapy: Physiotherapy is a RSI wrist treatment that involves exercises, stretches, massages, and other techniques that can help improve the function, strength, flexibility, and circulation of the wrist. Physiotherapy can also help prevent stiffness, scar tissue formation, and muscle atrophy in the wrist.
• Occupational therapy: Occupational therapy is a RSI wrist treatment that involves modifying the work environment, equipment, and habits that can cause or worsen RSI in the wrist. Occupational therapy can also help teach ergonomic principles, proper posture, and stress management techniques that can help prevent RSI in the wrist.
• Surgery: Surgery is a RSI wrist treatment that involves repairing or removing damaged tissues or structures in the wrist that cause RSI. Surgery is usually considered as a last resort when other treatments fail to provide relief or improvement. Some examples of surgery for RSI wrist treatment are:
  • Carpal tunnel release: Carpal tunnel release is a surgery that involves cutting the transverse carpal ligament that forms the roof of the carpal tunnel in the wrist. This can help relieve pressure on the median nerve that causes carpal tunnel syndrome.
  • Tendon release: Tendon release is a surgery that involves cutting or loosening the tendons that cause trigger finger or tennis elbow. This can help restore normal movement and function of the fingers or elbow.
  • Joint replacement: Joint replacement is a surgery that involves replacing a damaged or worn-out joint in the wrist with an artificial one. This can help restore mobility and function of the wrist.

RSI wrist treatment is important to avoid complications such as chronic pain, nerve damage, or disability.
