  Data collection instrument and scale Time points
Secondary outcome measures:
 Activity performance MAP-Hand, mean of 18 standardized and up to five patient specific activities, respectively, rating scale 1–4, 1 is no problems t1, t2*, t3, t4, t5
 Physical function and symptoms in the arm, shoulder and hand Quick-Dash, sum-score range 1–100, 1 = good function t1, t3, t4, t5
 Current situation with regards to main reason for wanting surgery Numeric rating scale: 0–10, 0 is as bad as could be t1, t3, t4, t5
 Pain at rest Numeric rating scale: 0–10, 0 is no pain. Both hands. t1, t3, t4, t5
 Grip strength In Newton by the Grippit; maximum, mean and last of 20 recordings over a 10 s interval, both hands t1, t3, t4, t5
 Pain following measure of grip strength Numeric rating scale: 0–10, 0 is no pain, both hands t1, t3, t4, t5
Tertiary outcomes:
 Current pain in thumb selected for surgery Numeric rating scale: 0–10, 0 is no pain t1, t3, t4, t5
 Painful finger joints Examination by a trained OT of presence of pain yes/no in CMC1, MCP, PIP and DIP-joints in both hands t1, t3, t4, t5
 Finger flexion Flexion deficit in millimetre of the II, III, IV and V finger of both hands t1, t3, t4, t5
 Range of motion thumb MCP In degrees by a goniometer, both hands t1, t3, t4, t5
 Range of motion thumb IP In degrees by a goniometer, both hands t1, t3, t4, t5
 Palmar abduction thumb In degrees by a pollexograph, both hands t1, t3, t4, t5
 Abduction CMC1 In degrees by a pollexograph, both hands t1, t3, t4, t5
 Pinch strength In Newton by the Grippit; maximum, mean and last of 20 recordings over a 10 s interval, both hands t1, t3, t4, t5
 Pain following measure of pinch strength Numeric rating scale: 0–10, 0 is no pain, both hands t1, t3, t4, t5
 Pain following exercising Exercise diary, numeric rating scale: 0–10, 0 is no pain t3
 Satisfaction with HOA care at current centre Numeric rating scale: 0–10, 0 is very dissatisfied t3, t4, t5
