Evidence-based practice

• Mehrholz et al. Electromechanical and
  robot-assisted arm training for improving arm
  function and activities of daily living after
  stroke. Cochrane Database Syst Rev. 2008.
• Not more likely to improve their activities of
  daily living
• Arm motor function and strength of the paretic
  arm may improve.
• However, the results must be interpreted with
  caution
• variations between the trials in the duration,
  amount of training and type of treatment, and in
  the patient characteristics.
