Area of Science:

  • Neurorehabilitation
  • Robotics in Medicine
  • Digital Health

Background:

  • Technological advancements challenge the traditional view of a limited recovery window post-stroke.
  • Robot-assisted therapy and serious games are emerging as novel rehabilitation tools.

Purpose of the Study:

  • To evaluate the effectiveness of robot-assisted therapy combined with a serious game for rehabilitation and motor assessment in chronic stroke patients.
  • To explore the correlation between robotic device output, game metrics, and clinical motor function scales.

Main Methods:

  • Assessed 8 chronic stroke patients using robot-assisted therapy and a serious game over 386 training sessions.
  • Utilized clinical motor scales (e.g., Fugl-Meyer upper extremity scale) for assessment.
  • Calculated robotic device output (mean force, force-position correlation) and game score elements (collisions, rewards, total score).

Main Results:

  • Some patients showed marginal to significant motor function improvements after a 10-week protocol.
  • Strong correlations were found between robotic parameters (mean force) and game metrics (collisions) with clinical motor scale scores.
  • Linear regression indicated these parameters are independent predictors of motor scale scores.

Conclusions:

  • Robot-assisted therapy integrated with serious games can facilitate clinical improvements in chronic stroke patients.
  • Robotic and game metrics show strong associations with clinical outcomes and can serve as predictors for rehabilitation progress.
