An Examination of Motivation in Physical Therapy Through the Lens of Self-Determination Theory: Implications for Game Design

Paper Information

• Subject Area: Exploring the application of motivation and game design in physical therapy through Self-Determination Theory (SDT)
• Keywords: Games, Motivation, Physical Therapy, Rehabilitation, Self-Determination Theory

Research Background and Issues

• Identified Problems or Challenges:

  • Many games designed for physical therapy focus on functional outcomes, neglecting the potential to optimize design by learning from therapists' practical experiences.
  • Game design often centers on data-driven performance adjustments, lacking adaptation based on patients' psychological states and contextual factors.
  • While motivation is widely recognized as critical in physical therapy, there is a lack of systematic theoretical guidance.

• Why It Matters:

  • Motivating patients is crucial for improving the effectiveness and sustainability of therapy, especially in physical therapy for children and adolescents.
  • Insufficient motivational support may lead to failed treatment plans or reduced efficiency.

• Research Motivation and Related Work:

  • In the fields of Human-Computer Interaction (HCI) and game studies, there is limited research leveraging therapists' practical methods in the design of therapeutic games.
  • Self-Determination Theory has demonstrated its potential for understanding motivation and guiding practice in psychology, education, and sports.

Proposed Solution

• Proposed Solution:

  • Use Self-Determination Theory as a theoretical framework to analyze therapists' practical methods through interviews, deriving insights for game design.

• Innovative Aspects:

  • Systematically analyze how therapists adapt their sessions to motivate patients using two sub-theories (Basic Psychological Needs Theory and Organismic Integration Theory).
  • Identify underutilized strategies in game design from therapeutic practices, such as focusing more on patients' emotional states and avoiding negative feedback.

• Implementation Steps:

  • Conduct semi-structured interviews with 12 therapists, focusing on how they tailor therapy to meet patients' needs and stimulate motivation.
  • Design interview questions based on SDT-related keywords, such as autonomy, competence, and relatedness.
  • Apply thematic analysis to systematically examine therapists' motivational strategies and conversational adjustments.

Research Findings

• Specific Findings:

  • Therapists intuitively apply Basic Psychological Needs Theory to support patients' experiences of competence, relatedness, and autonomy. This includes providing detailed feedback, avoiding experiences of failure, and using rewards to enhance motivation.
  • While therapists recognize the importance of autonomy, they often limit patient choices to ensure therapeutic goals are met, offering superficial choices (e.g., reward items) as psychological compensation.

• Advantages Compared to Existing Solutions:

  • Integrating therapeutic practices offers a new perspective for game design, focusing not only on skill and task alignment but also on patients' emotions, physical conditions, and environmental factors.
  • Proposes methods to avoid patient failure in games, contrasting with traditional game design's failure feedback mechanisms.

• Experimental or Evaluation Results:

  • Therapists' strategies successfully enhance patient motivation, such as through positive feedback, task difficulty adjustments, and fostering friendly therapeutic relationships.
  • Data indicates that therapists effectively use rewards and external feedback to promote patient engagement but lack structured methods to support intrinsic motivation.

• Limitations and Future Directions:

  • Limitations:

    • The study is based on a small sample (12 therapists) and a specific geographic region (Belgium).
    • Patients' perspectives or experiences were not fully explored.

  • Future Directions:

    • Expand target groups to include adult therapists and a broader population.
    • Develop an SDT-based game framework and evaluate its practical effectiveness.
    • Explore autonomy support issues in therapy more deeply from the patients' perspective.

In summary, this study provides a set of theory-driven game design recommendations through an empirical analysis of motivation theory, aiming to better serve physical therapy patients.
