Everyday technology — laptops, phones, tablets, and game controllers — has made almost everyone vulnerable to a repetitive stress injury (RSI). Younger generations are especially exposed, because their muscles and tendons are already under tension from growth. And when a child or teen complains of a sore wrist or aching shoulder, it's often dismissed as "growing pains." Left alone, a temporary problem can become a lasting one.
What parents should know: the most common repetitive stress injuries in children are tendonitis, bursitis, and carpal tunnel syndrome, and they're driven mainly by two habits — long, unbroken use of technology and carrying too much weight. Better posture, properly sized equipment, regular breaks, and a lighter backpack prevent most of them.
Preventing RSIs is part of building healthy study habits for kids from elementary school through college. Here's what to watch for and what to change.
Key takeaways
- Tendonitis, bursitis, and carpal tunnel syndrome all occur in kids and teens, not just adults.
- Teens are especially at risk because injuries can affect growth plates, where bones lengthen.
- Overuse of technology and overloaded backpacks are the two behaviors most linked to RSI in young people.
- Persistent pain, swelling, tingling, or weakness is not "growing pains" — have it checked.
What Are the Most Common Repetitive Stress Injuries in Children?
The three most common are tendonitis, bursitis, and carpal tunnel syndrome — the same conditions adults get from repetitive work. Each causes pain and swelling around the joints and, if untreated, can lead to temporary or long-term loss of motion.
| Condition | What it is | Signs to watch for | Common triggers in kids |
|---|---|---|---|
| Tendonitis | Inflammation of a tendon | Pain with movement, tenderness, mild swelling | Gaming controllers, long typing sessions, heavy texting |
| Bursitis | Inflammation of a bursa, the fluid-filled sac that lets a tendon glide over bone | Aching, stiffness, swelling near a joint such as the shoulder or elbow | Repetitive arm movements, leaning on elbows, heavy one-strap bags |
| Carpal tunnel syndrome | Pressure on the median nerve at the wrist | Pain, tingling, numbness, or weakness in the hand and fingers | Bent wrists while typing or gaming for long stretches |
Teens deserve extra attention. Their growth plates — the areas near the ends of bones where new bone forms as they lengthen — are more vulnerable to repeated stress, so an overuse injury during a growth spurt can be harder to shake.
Why Is RSI in Teens Becoming More Common?
RSI in teens is more common because young people spend more hours than ever on keyboards, phones, and controllers, often in postures and at furniture that don't fit them. Rising academic pressure adds long homework sessions on top of recreational screen time.
Two behaviors are linked most closely to RSIs in children and adolescents: overusing technology and carrying too much weight.
How Does Technology Overuse Cause Injuries?
Technology overuse causes injuries through repetition plus poor positioning: thousands of keystrokes, taps, or button presses made with bent wrists and raised shoulders. Computers, video games, and phones are all linked to extended use that can lead to tendonitis, bursitis, and carpal tunnel syndrome.
Computers and homework
Computers are designed for adult bodies, so their very use can cause problems for children. A monitor set too high or a keyboard just out of reach causes discomfort that builds over time. Aim for:
- Forearms roughly parallel to the floor, with elbows near 90 degrees and wrists straight.
- Feet flat on the floor — add a footrest if they don't reach.
- The top of the screen roughly level with the eyes; an adjustable monitor arm or laptop stand makes this easy across different body sizes.
- An adjustable chair with lumbar support for older kids and teens who study for long periods.

Kids gaming injuries
Kids gaming injuries usually come from marathon sessions slumped on a couch or bed, with wrists bent around a controller and the neck craned toward the screen. Encourage a supported seat, the screen at a comfortable distance, and a break at the end of every match or level. Our guide to gaming without the aches covers chairs, keyboards, and controller habits in more depth.
Texting and phones
Constant text messaging contributes to thumb, hand, and wrist injuries. Children and teens should avoid texting for long stretches and stop when they feel discomfort. Alternating hands and holding the phone higher, closer to eye level, takes stress off the joints and the neck.
Handwriting
Younger children can develop hand pain from gripping pencils too tightly during long writing assignments. Choosing the right grip and writing surface reduces that pressure.
How Does Carrying Too Much Weight Contribute?
Overloaded backpacks strain the back, neck, and shoulders, especially when carried on one side. At most, a child should carry 15 to 20 percent of their body weight in a backpack, and some doctors recommend staying closer to 10 percent to protect the spine and lower back.
- Pack heavy items in the main compartment closest to the back to even the load.
- Leave anything not needed for the next few hours in a locker or classroom.
- Choose an ergonomic backpack with wide padded straps, a waist strap that shifts weight to the hips, and smaller compartments that keep contents from shifting.
How Can Parents and Teachers Prevent RSIs?
Parents and teachers prevent RSIs by teaching good technique, fitting equipment to the child, and building in breaks. Use this quick prevention checklist:
| Area | Prevention habit |
|---|---|
| Breaks | Stand, stretch, and look away from the screen every 20–30 minutes |
| Setup | Feet supported, wrists straight, screen near eye level |
| Equipment | Child-sized keyboard and mouse, footrest, adjustable chair for teens |
| Devices | Limit long texting and gaming sessions; switch hands and activities |
| Carrying | Two straps, lighter load, heavy items close to the back |
| Symptoms | Take pain, tingling, or weakness seriously and see a doctor if it persists |

Frequently Asked Questions
Can children get carpal tunnel syndrome?
Yes. Although it's more common in adults, children and teens who spend long hours typing, gaming, or texting with bent wrists can develop carpal tunnel symptoms such as tingling, numbness, and hand weakness. Any persistent symptoms should be evaluated by a doctor.
How do I know if it's growing pains or an RSI?
Growing pains typically affect the legs, often at night, and aren't tied to a specific activity. Pain that shows up in the hands, wrists, elbows, or shoulders during or after repetitive activities like gaming or typing is more likely an overuse problem and worth discussing with your pediatrician.
How long should kids game or type without a break?
Aim for a short break every 20 to 30 minutes — standing up, shaking out the hands, and looking across the room. Ending sessions at natural stopping points, like the end of a level, makes breaks easier to stick to.
Can video games cause injuries in kids?
Long gaming sessions can contribute to thumb, wrist, neck, and back strain, especially when kids play slumped on a couch with bent wrists. A supported seat, regular breaks, and a sensible screen distance reduce the risk.
