Clinical characteristics of the CRPS participants.

# = patient number; Pain = average pain over the last 2 days rated on a visually presented numeric rating scale ranging from 0 to 10; T° affected (C°) = temperature of the affected hand in degree Celsius; T° unaffected (C°) = temperature of the unaffected hand in degree Celsius; T° diff = temperature difference between the affected–unaffected hand in degree Celsius; Volume affected (ml) = volume of the affected hand in milliliter; Volume unaffected (ml) = volume of the unaffected hand in milliliter; Volume diff = volume difference between the affected–unaffected hand in milliliter; DASH score = score calculated from the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; Activity affected-unaffected = Average vector magnitude count of the affected hand minus the count of the unaffected hand, as assessed with accelerometers, nr = data not recorded. Paired sample t-tests between the affected and unaffected hands for the volume and temperature parameters were not significant (all t(14) ≤ |.704|, p ≥ .493).
