Pinch differs from grip

Key pinch, tip pinch and three-point pinch are separate abilities. They fail separately and are trained separately.

Opposition is the thumb's job

Touching the thumb to each fingertip and to the base of the little finger is the range that opens jars and holds a pen.

Dexterity is trainable

Fine hand skill declines with disuse and improves with deliberate practice at any age.

Three couplets · two rounds · twelve minutes · hands that hold on

A

Pinch

Pinch strength test + opposition test
A1

Pinch strength test

60 s · slow reps

Pinch a set object for five seconds, rest five; count clean pinches and note any pain.

Easier gentler  ·  Harder firmer object

R1R2—
A2

Opposition test

10 reps · ×2

Thumb to each fingertip and to the base of the little finger; note how far it reaches.

Easier fewer targets  ·  Harder eyes closed

R1R2
B

Dexterity

Coin transfer test + thumb abduction test
B1

Coin transfer test

60 s · slow reps

Move coins one at a time between bowls for 60 s — count them and compare hands.

Easier larger objects  ·  Harder smaller objects

R1R2—
B2

Thumb abduction test

15 reps · ×2

Fifteen resisted thumb abductions each side; note which thumb fatigues first.

Easier gentler resistance  ·  Harder more resistance

C

Grip

Grip test + intrinsic hold test
C1

Grip test — Phase 3

60 s · slow reps

Pain-free grip, same object and method; compare with sessions 6 and 12.

Easier gentler  ·  Harder harder

Intrinsic hold test

3 × max · ×2

Hold the tabletop hand shape against light resistance to fatigue; time it.

Easier no resistance  ·  Harder more resistance

How to run it

  1. The thumb is forty per cent of hand function. It gets its own phase.
  2. Thumb-base arthritis loves the muscle beside the index finger — that one is trained every session here.
  3. Pinch is trained in a stable position: the thumb pad presses, the joint does not collapse.
  4. Dexterity is a skill. Practise it slowly and accurately before practising it fast.
