Cues
- Stay relaxed; precision over speed.
Common mistakes
- Pinching too hard.
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
- Time the chain length completed.
Regressions
- Larger clips.
What to do next — not a dead end
Suggestions use body region, goal, motion type, and allowed phases — not your medical record. After surgery or a flare, follow your clinician first.
