Grip strength in the dominant hand correlates well with certain anthropometric variables such as height, weight, BMI and total arm length and correlates indirectly with certain questionnaires [ 1– 5].
Certain questionnaires were reduced in length to reduce interview time for participants (e.g., the Discrimination Questionnaire was reduced, drug use questions were removed).
During the one year follow-up after the end of phototherapy (t=4 to t=9), we deliberately did not apply certain questionnaires (see fig 1).
