Single-Limb Single Hop Test for Distance
ICF category	Measurement of activity limitation, jumping
Description	The distance a patient travels when a single hop on 1 limb is performed.
Measurement method	The patient stands on the uninvolved limb, with toes on the starting line. The patient hops as far as possible forward and lands on the same limb. The distance hopped is measured from the starting line to the point where the patient’s heel landed. The patient is given 2 practice trials and 2 recorded trials. Testing is repeated on the involved limb. Wearing a functional knee brace is recommended for all patients postinjury or less than 1 year postsurgery.
Nature of variable	Continuous
Units of measurement	Centimeters
Measurement properties	Test-retest reliability Healthy individuals: ICC_2,3 = 0.92, SEM = 4.61 cm, MDC₉₅= 12.78 cm¹³⁶ Mean distance: 208.08–208.24 cm LSI reliability in patients with ACL reconstruction¹²⁹ ICC_2,1= 0.92 MDC₉₀= 8.09% Range of mean LSI at 16 weeks post-ACL reconstruction = 81.0%–82.9% Mean LSI at 22 weeks post-ACL reconstruction = 88.2%
