Methods matter- construct validity of steps per day in patients with lumbar spinal stenosis
Purpose: This study aimed to evaluate the ability of a thigh-worn accelerometer to detect walking during daily life in individuals with Lumbar Spinal Stenosis (LSS). Two hypotheses were made regarding how walking measurements from the accelerometer, a walking test, and an ankle-worn StepWatch would relate in order for the accelerometer to be valid. The hypotheses were: (a) there is no difference b
