Some jobs may require a person to stand or sit in one place for long periods, whereas others call for frequent repetitive motions, which over time, can cause serious injuries and physical harm to the body.
The following are some of the most common repetitive motions that may eventually lead to injuries:
- Using a computer mouse
- Working on an assembly line
- Using a cash register
- Scanning items
- Using tools/machinery
- Frequent lifting of heavy objects
- Moving cargo/inventory
- Carrying heavy items
Furthermore, people who work in certain conditions are more likely to develop repetitive motion injuries. Inadequate ergonomics, cold temperatures, and poor posture are examples of such conditions.
Injuries can be divided into two categories:
- Traumatic injuries
- Cumulative injuries
Traumatic injuries are the result of one-time incidents, such as a fall, whereas cumulative injuries are the result of repeated stress and damage over time.
Any physical injury caused by the repeated use of muscles, nerves, tendons, or other body parts is referred to as a repetitive motion injury, also known as a repetitive stress injury or repetitive strain injury.
What are the most common repetitive motion injuries?
Anyone who works in a job that requires them to perform the same tasks involving certain movements repeatedly is at risk of repetitive motion injuries.
The most common repetitive motions injuries include:
- Tendons are bands of fibrous tissues that connect muscles to bones. Although tendons are extremely strong, repetitive motion can cause tendinitis (inflammation of tendons).
- The shoulders, biceps, and elbows are the most common places for this inflammation to appear.
- A bursa is a cushioning sac present at various joints. There are over 150 bursae in your body, most of which are found in the elbows, knees, and hips.
- Bursitis occurs when that sac becomes inflamed and irritated due to pressure and repetitive movements.
Carpal tunnel syndrome
- Caused by a pinched median nerve in the wrist, which is usually the result of prolonged exposure to vibration or repeated forceful pressure.
- Tingling, numbness, and pain in the hand are all possible symptoms.
- Inflammation of a tendon and its protective sheath.
- It can result in joint pain, swelling, and stiffness.
Thoracic outlet syndrome
- A group of disorders is caused by compression of blood vessels or nerves in the thoracic outlet (the space between your collarbone and your first rib).
- This can result in shoulder and neck pain, as well as numbness in your fingers.
What are common signs and symptoms of repetitive motion injuries?
The signs and symptoms of repetitive motion injuries depend on the body part which is prone to repeated use in daily life.
Common signs and symptoms include:
- Severe pain
- Could be a burning, aching, or shooting pain
- Could be local or widespread
- May get exacerbated after a long session of repeated use
- Fatigue and weakness
- Tingling, numbness, or loss of sensation
- Lack of strength
- Lack of control or coordination
- Reduced flexibility or range of motion
In addition to these symptoms, some behavioral changes may occur in the affected individual, who may:
- Avoid using the affected part.
- Find alternative ways to cope with daily tasks.
- Avoid wearing or buying certain kinds of clothing because it is too difficult to put them on.
What are treatment options for repetitive motion injuries?
Repetitive motion injury treatment varies depending on the area affected, the severity of the condition, and whether any underlying conditions are present.
Common treatment options may include:
- Medication: To alleviate pain, anti-inflammatory medications (such as aspirin or ibuprofen), muscle relaxants, or antidepressants may be used.
- Heat or ice therapy: Ice or heat therapy can help reduce swelling and pain.
- Splinting: Offers support and strength.
- Injections: Steroid injections may be recommended for some people.
- Surgery: Often used as a last resort when other treatments are ineffective or unlikely to provide relief.
- Physiotherapy: To reduce stress on the affected area and improve its strength and function, exercises, bracing, and manual therapy are combined with patient education.
Prevention can be better than treatment in people who are at risk of repetitive motion injuries. You should always try to take regular breaks from your repetitive activity, such as standing up and walking around or simply wiggling your fingers and flexing your wrists regularly. Activity modification can help reduce symptoms and speed healing.
An ergonomic workplace redesign is generally a good idea. It is best to speak with your employer, who may be able to make accommodations for you.

BursitisA bursa is a fluid-filled sac found in the joints that cushions them. Bursitis is an inflammation of the bursae, most commonly caused by repetitive motion. Bursitis can be caused by a bacterial infection and should be treated with antibiotics. Doctors also recommend icing and resting the joint.
What Is the Best Thing to Do for Carpal Tunnel Syndrome?Managing pain from carpal tunnel syndrome may include rest, wearing a wrist splint and performing special wrist exercises. In more severe cases, medications and surgery may be required.
Bursitis Symptoms and TreatmentsDiagnosed with bursitis? Learn about treatment and prevention for trochanteric bursitis, as well as hip, knee, shoulder and other bursitis types.
Carpal Tunnel SyndromeCarpal tunnel syndrome is a condition in which irritation of the wrist's median nerve causes tingling and numbness of the thumb, index, and the middle fingers. Treatment of carpal tunnel syndrome depends on the severity of the symptoms and the nature of any disease that might be causing the symptoms.

De Quervain's TenosynovitisDe Quervain's tenosynovitis is inflammation of the tendon on the side of the wrist at the base of the thumb. De Quervain's tenosynovitis can be caused by a simple strain injury to the extensor pollicus longus tendon. Typical causes include stresses such as lifting heavy grocery bags by the loops, and lifting up gardening pots. Treatment for de Quervain's tenosynovitis includes any combination of rest, ice, anti-inflammatory medication, and/or cortisone injections.
Hamstring InjuryHamstring injuries may range from minor strains to major ruptures. A hamstring injury causes spasm, tightness, and tenderness. More severe injuries may cause swelling and bruising. While most hamstring injuries heal without surgery, a complete rupture would require surgery.
Head Injury (Brain Injury)In the United States, head injuries are one of the most common causes of death and disability. Head injuries due to bleeding are generally classified by the location of the blood within the skull, these include epidural hematoma, subdural hematoma, subarachnoid bleed, intracranial bleed, sheer injury, edema, and skull fracture. Some common symptoms of a head injury include vomiting, bleeding from the ear, speech difficulties, paralysis, difficulty swallowing, and body numbness. Treatment of a head injury depends on the type and severity of the injury.
Rotator Cuff Tear and InjuryRotator cuff injury is damage to any of the four tendons that stabilize the shoulder joint. Shoulder pain and tenderness are common symptoms. Rotator cuff disease treatment depends on the severity of the shoulder injury.
