StrengthThumbPalmisometricoppositionLow riskPhases 2, 3, 4

Goal

Axial thenar RIM builds endurance with lower joint compression than pinch.

Motion taxonomy (reference)

Also called: RIM · thenar isometric

Best for

  • Thenar endurance without pinch compression
  • CMC irritability

Default dose

Reps8
Frequency2× daily
Sets / time2 rounds

8 reps • 2 sets • 4s hold • 2×/day

Equipment

Towel or soft pad

Avoid when

  • Acute thenar space infection
  • Unstable CMC

Measurement targets

  • Hold seconds

Setup

  • Place a folded towel or soft pad on a table.
  • Rest the thenar eminence on the pad with wrist neutral.

Steps

  1. 1Press the thenar straight down into the pad without sliding.
  2. 2Hold steady submaximal pressure.
  3. 3Relax between reps.

Cues

  • Pressure through the muscle bulk, not the CMC corner alone.

Common mistakes

  • Rolling into extreme opposition to force load.

Stop if you feel

Stop rules

  • Sharp pain (≥ 4/10)
  • Increasing swelling during or after
  • New or worsening numbness or tingling
  • Color change in fingers (pale, blue, red)
  • Wound opens, drains, or feels hot
  • Next morning is worse than the day before

Progressions

  • Slightly firmer pad stack when symptom-free.

Regressions

  • Lift hand 1 mm off pad — hover isometric.
Continue your rehab

What to do next — not a dead end
