AB  - A paucity of objective outcome measures exists for assessing movement disorders, 
      including degenerative lumbar spinal stenosis (LSS). Fitts's Law provides a novel 
      approach to clinical outcome measurement since performance is resistant to 
      learning, and task difficulty can be altered. The objective of the present study 
      was to compare, using a Fitts's task, movement performance of individuals with 
      and without LSS to determine if motor difficulties that arise with LSS impede the 
      planning, initiation, or execution of deliberate lower limb movements. Twelve 
      pre-surgical LSS patients and twelve control participants from the community 
      performed a Fitts's Law (foot reaching) task, while LSS participants also 
      completed pain and disability questionnaires. Fitts's Law was evident for both 
      groups, however the LSS group's movements were more adversely impacted as task 
      difficulty increased. Specifically, the LSS group's movement time and time to 
      peak velocity (ttPV) increased as task index of difficulty increased, while peak 
      velocity decreased. Correlations between ttPV and leg pain, and with stenosis 
      impairment severity respectively, provided evidence that less support leg pain 
      and less stenosis impairment severity yield faster ttPV in the moving leg at the 
      highest index of difficulty. Therefore a lower extremity Fitts's Law task 
      captured differences in the planning and execution of leg movements between 
      healthy and LSS populations.
