Hand Therapist Nigel Chua

Loaded trays on a bent-back wrist, three-plate carries, shaking and corkscrews. The wrist, thumb and elbow problems waiting and bar staff get, and the carrying changes that fix most of them.

A thin stylus pinched hard for hours, strokes drawn from the wrist, and a finger held on a shortcut key. The hand and wrist problems digital artists get, and the settings and setup changes that fix most of them.

Your whole body weight on your grip, upside down, with wrists and elbows at end of range. The forearm, elbow and wrist injuries pole and aerial athletes get, and the training changes that prevent them.

Shaping rice, long single-bevel knives, and raw fish handled with cold, nicked hands. The overuse problems, cuts, and fish-specific infections sushi chefs need to recognize early.

Thousands of throws, catches and wrist rotations per session. The forearm, wrist and finger injuries jugglers, poi spinners and contact jugglers get, and the practice changes that prevent them.

Thousands of light items a shift, each one rotated to find a barcode. The repeated-rotation injury checkout work causes, what the workstation does, and the thirty-second adjustment that matters.

One of the few jobs where the hands are the entire output, at a pace set by someone else. The repetition load, what it causes, and why team rotation is the only real control.

Rugby produces more hand fractures and dislocations than almost any team sport, in a culture of strapping it and playing on. The two injuries with deadlines, and the infection risk nobody mentions.

Holding two kilos at arm’s length for ten hours is a static load with a long lever. What each hand does, why the edit counts as part of the same load, and the changes that reduce it.

The drawing hand takes tension, the bow hand takes compression, and the injuries split cleanly between them. What each one produces, and why gripping the bow is both a form fault and a wrist problem.
