“Text neck” sounds like a throwaway term, but it describes a genuinely measurable musculoskeletal problem — and if you spend hours a day looking down at a phone, there’s a good chance it’s contributing to your neck and shoulder pain.

The physics of looking down

Your head weighs roughly 4.5-5.5kg in a neutral position. But most people don’t hold their phone at eye level — they look down at somewhere between a 45 and 60 degree angle. At that angle, the effective load on the cervical spine has been estimated at around 27kg (roughly 50-60 pounds) of force — several times the head’s actual weight, simply due to leverage.

Held for a few seconds, that’s nothing. Held for hours a day, every day, it’s a completely different story for the muscles trying to hold your head up against that load.

What the research actually finds

Studies looking specifically at smartphone use and musculoskeletal symptoms have found neck pain, headaches and shoulder pain are the most commonly reported issues among frequent users — with neck pain reported by roughly two-thirds of people surveyed in one study, and shoulder pain by over 40%. The association was strongest among people using their phones for more than five hours a day, which describes a large share of the population now.

Why this creates a persistent pattern, not just a passing ache

The forward head posture involved in “text neck” doesn’t just strain the neck in the moment — it changes muscle activity patterns over time. Certain muscles (particularly the upper trapezius and suboccipitals) end up chronically overworked trying to compensate, while deeper stabilising muscles become inhibited. This is exactly the kind of pattern that tends to show up on our Neck & Shoulder Pain page — trigger points and referred pain that persist well beyond any single day’s phone use, because the underlying postural load never really lets up.

What actually helps (beyond “look at your phone less”)

Reducing phone time and holding devices higher obviously helps, but for most people that’s not a realistic full fix — the postural load has usually already created real, physical trigger points and muscle imbalances that don’t just resolve because you changed a habit. This is where targeted treatment comes in:

• Dry needling directly releases the trigger points in the upper trapezius, levator scapulae and suboccipital muscles that build up from sustained forward head posture.
• Motor point needling with electrostimulation can help reset muscles that have become chronically inhibited or overworked, restoring more normal activation patterns rather than the compensatory ones your body adapted into.

A habit worth building anyway

Even with treatment, small habit changes help maintain the results — holding your phone higher, taking regular breaks to look up and roll your shoulders back, and being mindful of posture during long scrolling or reading sessions. But if the pain and tension are already well established, habit changes alone usually aren’t enough to unwind it.
