The purpose of this study was to determine which of several crutch -fittingtechniques best predicts ideal crutch length. ldeal crutch length is defined as thelength of the crutch, including accessories, obtained during stance when the crutchtip is 6 inches (15.2 cm) lateral and 6 inches(15.2 cm) anterior to the fifth toe andthe axillary pad is 2.5 inches(6.4 cm) below the axillary fold. Forty four volunteerswere measured for crutches using each of the following methods:(l) 77% of actualheight , (2) actual height minus 40.6 cm, (3) actual height minus 45.7 cm, (4)olecranon to opposite third finger tip, (5) olecranon to opposite fifth finger tip, (6)77% of arm span, (7) arm span minus 40.6 cm, (8) anterior axillary fold to heelplus 5.1 cm, (9) anterior axillary fold to heel plus 10.2 cm, (10) ideal crutch length. Of the techniques studied, the two involving anterior axillary fold to heel werefound to be good predictors: anterior axillary fold to heel plus 5.1 crn and anterioraxillary fold to heel plus 10.2 cm. Finally, two additional length estimates werederived using linear regression analyses. These estimates provided the best overallpredictors based on anterior axillary fold to heel and actual height.
