Conditions & Injuries

Piano is a volume problem: tiny forces, enormous repetitions, and a wrist that barely moves. What it loads, what the bench height does, and the condition that isn’t an injury at all.

The only position where hands are the tool. The finger injuries keepers accumulate, how to tape properly, and the one that quietly causes permanent deformity if it’s missed.

A fielder’s injury has nothing in common with a spinner’s. Finger injuries from catching, what spin bowling does to the skin and joints, and the palm fracture that hides on X-ray.

Bowler’s thumb is a nerve injury that barely exists outside this sport. What it feels like, why ball fit is the whole treatment, and the rest of what ten-pin does to a hand.

Precision pinch, vibration and fixed wrist angles, for hours. What dentistry does to hands, which instrument changes are worth making, and the marker that means you already have a problem.

Writing hand pain is a grip problem plus a volume problem. How to tell you’re gripping too hard, how to build handwriting tolerance before exams, and the one presentation that isn’t overuse at all.

The fretting hand and the picking hand fail in completely different ways. What goes wrong in each, the setup changes that reduce load more than any exercise, and the problem that isn’t an injury at all.

Skiers fall holding a pole, so the thumb takes it. Snowboarders put a palm down, so the wrist does. Which injury belongs to which sport, and why both get dismissed as sprains.

Grip, vibration and weight through an extended wrist, for hours. Arm pump, the two nerve compressions riders get, what the throttle position does, and the crash injuries gloves hide.

CrossFit asks the hands to hang, grip near-maximally and absorb friction in the same hour. Rips, wrist extension, pulley injuries and the elbow pop that ends a season — plus what actually prevents them.
