What is carpal tunnel and why is it relevant in the workplace?

The carpal tunnel is a narrow passageway inside the wrist made of bones and ligaments. Running through it is the median nerve, which controls sensation and movement in parts of the hand. When this tunnel becomes compressed or inflamed, the median nerve is squeezed, resulting in pain, tingling and weakness. This is what we call carpal tunnel syndrome. In the workplace, especially in environments where repetitive hand or wrist motions are routine, think keyboard work, assembly line tasks, using of handheld tools or prolonged driving, the risk of developing carpal tunnel rises sharply

Recognising the signs of carpal tunnel syndrome

People often describe the early stages of carpal tunnel as a tingling or “pins and needles” sensation in the thumb, index and middle fingers. Others may notice numbness at night that wakes them from sleep or a tendency to drop objects due to weakened grip strength. Over time, pain may spread up the arm and tasks that once seemed effortless become more difficult. Being aware of these signs matters. Workers may not immediately attribute their discomfort to carpal tunnel, especially if it develops slowly. Early recognition makes intervention more effective and can prevent the condition from worsening.

Understanding what causes carpal tunnel syndrome

Repetitive motion is a key factor, but it isn’t the only one. Forceful gripping, awkward wrist positions, vibration from tools and prolonged computer use all increase strain on the wrist. Beyond workplace activity, certain health conditions such as diabetes, arthritis and pregnancy can also make someone more susceptible. What links all these factors is pressure within the carpal tunnel itself. Whenever the structures inside swell or the space narrows, the median nerve becomes compressed. This is why risk assessments must consider both job role and the individual’s health profile.

Preventing carpal tunnel before it develops

Ergonomics, the science of fitting the job to the worker rather than the worker to the job, plays a central role in building safer workplaces. Adjustable chairs, desks at proper heights, split keyboards, cushioned mouse pads and well-balanced tools all reduce strain on the wrist. Regular breaks to stretch and reposition hands can also give the median nerve time to recover. Education is equally important. Workers who understand the risks of repetitive motion are better equipped to avoid unnecessary strain and flag symptoms early.

Treating carpal tunnel once it appears

When carpal tunnel syndrome does develop, treatment options vary depending on severity. In mild cases, simple changes such as resting the wrist, using a supportive splint at night or applying cold packs can ease symptoms. Physiotherapy and specific exercises to stretch and strengthen the wrist and hand muscles often help. If symptoms persist, healthcare professionals may recommend corticosteroid injections to reduce inflammation or, in more advanced cases, surgery to relieve pressure on the median nerve. The important thing is that treatment should be guided by a qualified clinician.

How employers can support workers with carpal tunnel syndrome

Employers have both a legal and a moral duty to protect workers from occupational hazards. When it comes to carpal tunnel syndrome, this means more than just making adjustments after a diagnosis. Risk assessments, ergonomic workplace design and safety training is essential. For workers already affected, reasonable accommodations should be introduced, such as modifying duties, offering adaptive equipment and providing time for medical appointments. Maintaining confidentiality and showing empathy, makes it easier for workers to be forthcoming about their condition and symptoms.

Bringing it all together

Carpal tunnel syndrome may start with a tingle in the fingers, but if left unaddressed it can become a life-altering condition. At MOHS our experiences prove that the best outcomes occur when employers and employees work together. By combining ergonomic design, health education and timely intervention, organisations can reduce the toll of carpal tunnel syndrome and create workplaces where everyone’s hands, and livelihoods, are protected.
