Wrists bent at angles, shoulders hunched forward, neck craned toward a screen
En un momento en que las pantallas se han convertido en el horizonte cotidiano de millones de jóvenes, el Ministerio de Salud del Perú advierte que las horas acumuladas frente a teclados y controles están dejando una huella silenciosa en manos y muñecas. Lo que comienza como una postura incómoda puede convertirse, con el tiempo, en una lesión crónica que limita la vida diaria. La medicina conoce estas condiciones desde hace décadas, pero su aparición masiva entre adolescentes y adultos jóvenes representa un capítulo nuevo en la historia del cuerpo humano frente a la tecnología.
- El uso prolongado de dispositivos digitales con mala postura está generando una ola silenciosa de lesiones crónicas en manos y muñecas entre jóvenes peruanos.
- El síndrome del túnel carpiano y la tenosinovitis de De Quervain —antes asociados a trabajadores adultos— ahora afectan a adolescentes que pasan horas jugando o programando.
- Los síntomas como hormigueo, entumecimiento y debilidad en las manos suelen ignorarse hasta que interfieren con actividades básicas, lo que agrava el pronóstico.
- La especialista del Instituto Nacional de Rehabilitación emitió guías concretas: pausas cada 50 minutos, altura de escritorio adecuada y ejercicios de estiramiento como medidas inmediatas.
- El mensaje oficial es urgente: atender los primeros síntomas hoy puede evitar que una generación entera cargue con dolor crónico mañana.
Los jóvenes peruanos pasan horas sin precedentes frente a teclados y consolas de videojuegos, y el Ministerio de Salud ha comenzado a alertar sobre las consecuencias físicas de esa rutina. La doctora Doris Apaza Muñoz, especialista en rehabilitación del Instituto Nacional de Rehabilitación, emitió orientaciones formales ante el crecimiento notable de lesiones musculoesqueléticas en adolescentes y adultos jóvenes.
El problema central es el efecto acumulativo de las posturas forzadas: muñecas dobladas, hombros encorvados, cuello inclinado hacia la pantalla. Con el tiempo, estas posiciones dañan músculos, huesos y articulaciones. La lesión más frecuente es el síndrome del túnel carpiano, causado por la compresión del nervio mediano en la muñeca debido a movimientos repetitivos y mala posición de las manos. Los pacientes sienten hormigueo, entumecimiento o debilidad, síntomas que suelen empeorar de noche o tras largas sesiones frente a la pantalla.
Otra lesión común es la tenosinovitis de De Quervain, una inflamación de los tendones del pulgar provocada por el agarre constante de controles, teléfonos y otros dispositivos. El dolor puede volverse agudo y limitar incluso movimientos simples.
La prevención exige cambios concretos: mantener la muñeca alineada con el antebrazo, hacer pausas de cinco minutos cada cincuenta de actividad, usar un escritorio a unos 75 centímetros de altura y elevar la pantalla al nivel de los ojos. El uso de teclados y ratones externos también reduce los ángulos incómodos que imponen los portátiles.
La advertencia es clara: estas lesiones son evitables si se actúa a tiempo. Cualquier señal de hormigueo o debilidad persistente merece una evaluación especializada, porque ignorar los síntomas tempranos puede traducirse en dolor crónico que acompañe a toda una generación.
Young people in Peru are spending unprecedented hours hunched over keyboards and gaming consoles, and the country's health ministry is now sounding an alarm about what that posture is doing to their hands and wrists. The problem is not new in medicine, but its scale among teenagers and young adults has grown sharply enough that Dr. Doris Apaza Muñoz, a rehabilitation specialist at Peru's National Rehabilitation Institute, felt compelled to issue formal guidance on prevention.
The issue centers on what happens when the body holds unnatural positions for extended periods. Forced postures—wrists bent at angles, shoulders hunched forward, neck craned toward a screen—do more than cause temporary discomfort. Over time, they create lasting damage to muscles, bones, and the joints that connect them. The sedentary nature of gaming and computer work compounds the problem: the body stays still while specific small muscles and tendons bear repetitive strain.
The most common injury Apaza Muñoz encounters is carpal tunnel syndrome, a condition in which the median nerve becomes compressed at the wrist. It typically develops from the combination of repetitive keyboard and mouse movements paired with poor hand positioning. Patients report tingling, numbness, a pins-and-needles sensation, loss of feeling, or weakness in the hands—symptoms that often intensify at night or after long gaming sessions. The condition can progress to the point where basic tasks become difficult.
A second frequent injury is De Quervain's tenosynovitis, an inflammation of the tendons that control thumb movement. It arises from the constant gripping and repetitive motions required by game controllers, smartphones, and other handheld devices. The pain can be sharp and limiting, making even simple pinching motions uncomfortable.
Prevention, according to the specialist, requires deliberate changes to how young people set up their gaming and work spaces. The wrist should remain straight and aligned with the forearm—not bent upward or to the side when using a mouse or keyboard. Every fifty minutes of activity should be interrupted by a five-minute break dedicated to stretching the neck, wrists, and back. A standard desk height of approximately 75 centimeters, with a chair adjusted so the arms rest level with the work surface, creates a foundation for neutral posture. Stress balls or elastic bands can build strength and flexibility in the fingers. The laptop screen should be elevated to eye level, and external keyboards and mice should replace the built-in versions that force awkward angles.
The health ministry's message is clear: these injuries are preventable, but they require attention now, before they become chronic. Any sign of tingling, numbness, or persistent hand weakness warrants a visit to a health facility for evaluation by a specialist. The cost of ignoring early symptoms is a generation of young people managing long-term hand and wrist pain that could have been avoided with better habits established today.

Why is this happening now, specifically? Hand injuries from repetitive work aren't new.
The scale is new. Gaming and esports have exploded among young people in Peru—hours every day, often in makeshift setups with no ergonomic thought. It's the volume and the age of the people affected that's changed.
So it's not that the injury itself is different, just that more teenagers are getting it?
Exactly. Carpal tunnel has existed for decades in factory workers and typists. But now you have 14-year-olds developing it. That's the alarm.
What makes De Quervain's different from carpal tunnel?
Location and cause. Carpal tunnel is about nerve compression at the wrist. De Quervain's is inflammation of the tendons that move your thumb—it comes from gripping controllers and phones. Same root cause, different anatomy.
If someone feels tingling at night, is that already serious?
It's a warning. It means the nerve is already irritated. That's when you need to see a specialist, before it becomes constant pain that doesn't go away even when you rest.
The fifty-minute break recommendation—is that based on research, or just practical advice?
It's practical ergonomic guidance. The idea is that micro-breaks prevent the cumulative strain that leads to injury. You're giving tissues time to recover before damage accumulates.
What happens if someone ignores the early signs?
It becomes chronic. Pain that persists whether you're gaming or not. Loss of grip strength. Difficulty with everyday tasks. That's when you're looking at months of rehabilitation, not prevention.
