Relieve sore, tight muscles at home

Your neck and shoulder muscles are designed to move, contract, and then relax.

But long hours at a desk, poor posture, workouts, lifting, and everyday stress can keep those muscles working for longer than they should.

Instead of fully relaxing, they can stay tense and overworked throughout the day. Over time, this can lead to stiffness, discomfort, and that tight feeling that makes even simple movement less comfortable.

Ultrasound Flex uses targeted therapeutic ultrasound designed to gently warm deeper muscle tissue.

This helps support muscle relaxation, circulation, and temporary relief from everyday tension and stiffness — all in simple 10–15 minute sessions at home.

When tight muscles don’t fully switch off

Muscle tension often isn’t caused by one bad day.

It can build gradually from hours of sitting, looking at screens, poor posture, physical work, or repeated training.

When muscles stay under constant strain, they may remain tense even after the activity is over.

Ultrasound Flex is designed to deliver gentle therapeutic ultrasound into the muscle tissue, helping support relaxation where that tightness develops.

So instead of only treating the surface, you can support tight, overworked muscles as part of your regular recovery routine.

More than temporary relief

When your neck or shoulders feel tight, stretching, painkillers, heating pads, or massage can feel helpful in the moment.

But temporary relief doesn’t always stop the tension from returning.

Ultrasound Flex offers a different approach by using therapeutic ultrasound to gently warm deeper muscle tissue and support circulation and natural muscle relaxation.

No appointments.

No waiting rooms.

Just convenient at-home support whenever your muscles need it.

Support everyday muscle recovery

Tight muscles can make turning your head, lifting your arm, training, or simply getting through the day feel less comfortable.

Regular 10–15 minute Ultrasound Flex sessions are designed to support muscle relaxation, circulation, and everyday recovery.

Whether your tension comes from desk work, poor posture, physical activity, or daily strain, Ultrasound Flex gives you a simple way to support sore, tight muscles from home.

Used in Physiotherapy for Decades

Therapeutic ultrasound has been used by physiotherapists for decades to support muscle relaxation, mobility, and recovery.

But regular clinic visits can be costly, time-consuming, and inconvenient.

4Brune Ultrasound Flex brings therapeutic ultrasound technology into a simple at-home format, giving you targeted support whenever it fits your routine.
