Doctors Link Prolonged Screen Use to Muscle and Joint Strain

Extended use of computers and smartphones can contribute to neck and back pain, eye fatigue, and discomfort in the hands and wrists, according to health experts cited by NPR, The Times of India and Gulf News in reports published between October 17 and October 22, 2026. Doctors and physical therapists recommend regular movement, ergonomic adjustments and breaks to reduce physical strain without eliminating digital devices from daily life. Adults in the United States spend an average of 9.5 hours sitting each day, according to NPR.

Research conducted by Columbia University Medical Center in 2023 found that walking for five minutes every 30 minutes was the most effective strategy tested for reducing the potential harms of prolonged sitting. More than 20,000 participants in an NPR Body Electric challenge tested the walking routine and reported improved productivity and reduced fatigue.

Physical therapist Vinh Pham recommends movements that improve thoracic spine mobility to address discomfort associated with slouching. His 3D T-spine rotation exercise combines side bending, backward bending and twisting to help the spine move through different positions.

The exercise involves standing with one foot crossed behind the other, raising one arm overhead and placing the opposite arm behind the body before rotating toward the rear foot. The movement is repeated 10 times on each side. Prolonged screen viewing can also cause digital eye strain because the eyes must maintain close focus. Symptoms may include tired eyes, headaches and blurred vision.

Biomechanist Katy Bowman and physical therapist Leada Malek advise changing positions throughout the day rather than trying to maintain one supposedly perfect posture. Alternating between sitting, standing, reclining and walking can reduce the time the body spends in a fixed position. Malek, author of Science of Stretch, describes useful positions as adaptable and dynamic, meaning people should be able to move between them easily. Bowman and Malek share a principle commonly used by physical therapists: "Your best posture is your next posture."

Ergonomic adjustments can also reduce strain during computer use. Professional ergonomist Meg Honan recommends positioning monitors at eye level and keeping keyboards and mice low enough to prevent users from raising their shoulders while typing. For laptop users, an external keyboard and mouse can allow the screen to sit higher while the arms remain relaxed.

NPR reports that this arrangement can also reduce the repetitive strain associated with using a trackpad. Children face similar concerns as digital devices become increasingly common in education and recreation. In an October 17 report, The Times of India cited pediatrician Dr.

Akshay Mehta, a Consultant Neonatologist and Paediatrician at Motherhood Hospital in Greater Noida, who described neck pain, upper and lower back discomfort, stiffness and headaches among children aged 8 to 16 seen in clinical practice.

Mehta said the duration and manner of screen use, rather than screens alone, are important considerations. Prolonged forward bending forces the neck, shoulder and back muscles to work continuously to support the head.

Using laptops on beds, sofas or floors can make it harder for children to maintain a neutral posture. Mehta recommends suitable chairs and tables, screens positioned near eye level, regular movement breaks, adequate sleep, daily stretching and outdoor physical activity. Persistent pain, symptoms that interfere with sleep or everyday activities, frequent headaches, numbness, weakness or changes in posture warrant medical evaluation, according to Mehta.

He advises parents to encourage safer technology habits rather than banning devices entirely. Smartphone use presents a separate challenge for the hands and wrists. Gulf News reported on October 19 that UAE specialists found insufficient scientific evidence to establish that smartphone use directly causes osteoarthritis or rheumatoid arthritis, although repeated tapping, swiping and gripping can strain muscles, tendons and surrounding soft tissues.

Dr. Tania Sultana Memon, a Rheumatology Specialist at NMC Royal Hospital DIP Dubai and a member of the Middle East Arthritis Foundation, said device weight, grip and usage patterns influence the strain placed on the hands.

Large or heavy phones may increase muscular fatigue when held for extended periods, particularly in one hand. Repetitive movements without sufficient rest can also aggravate discomfort during smartphone use, laptop typing and mouse operation. Memon explained that phone-related strain can produce aching around the thumb and wrist that may improve with rest and reduced repetitive movement. Osteoarthritis involves joint damage, while rheumatoid arthritis is an autoimmune condition that causes joint inflammation.

Osteoarthritis can cause pain during gripping, opening jars or turning keys, as well as stiffness after rest and bony bumps around finger joints. Morning stiffness often subsides within 30 minutes. Rheumatoid arthritis can cause persistent pain, swelling, warmth and prolonged morning stiffness, often affecting several joints in both hands. Some people also experience unusual fatigue, and symptoms alone may not establish the underlying condition.

Dr. Chaitanya D, a Consultant Orthopaedic, Hand and Microsurgeon at Medcare Orthopaedics & Spine Hospital, said prolonged repetitive movements without adequate rest are a greater concern than occasional phone use. The thumb is particularly vulnerable because it performs many of the movements required for typing, scrolling and navigating a screen.

Mobile gaming can add strain through sustained gripping and rapid, repetitive tapping. Switching hands, supporting a phone on a surface or in the palm, and taking regular breaks can reduce the workload on the same muscles and tendons. People with persistent pain, joint swelling or prolonged morning stiffness should seek medical assessment rather than assume their symptoms are caused solely by device use.

Gulf News also described a published two-case report titled Cellular Phone Overuse as A Cause for Trapeziometacarpal Osteoarthritis: A Two Case Report. The report included a 33-year-old woman who experienced wrist pain after using her smartphone for several hours daily, with an MRI showing inflammation around the joint at the base of her thumb.
