The potential of cineplasty in the contemporary society
Investigating a historical technique for prosthetic hand control
This graduation project explores the contemporary relevance of cineplasty, a historical surgical technique that directly couples a muscle to a prosthetic device to provide intuitive mechanical control and natural proprioceptive feedback. Although cineplasty declined after the rise of non‑invasive myoelectric prostheses, its unique sensory advantages raise the question of whether a modernised version could still offer value today. A scoping review, literature research, semi‑structured interviews, shadowing sessions, and stakeholder mapping were conducted to assess its feasibility and desirability. Findings show that existing scientific evidence is limited and historically dated, while expert interviews highlight a clear trade‑off between proprioceptive benefits and concerns regarding aesthetics, surgical invasiveness, and alignment with modern patient expectations. Users increasingly prioritise appearance, and non‑surgical solutions, which places cineplasty at a disadvantage despite its functional strengths. Through iterative design exploration and expert‑validated prototyping, the project identifies a specific user group that may benefit from a renewed form of cineplasty. A modernised version is proposed, including surgical adaptations for improved cosmetic outcomes and a protective Cover to conceal and safeguard the cineplastic connection. Overall, cineplasty presents both promising opportunities and significant constraints, warranting further research and modernised design approaches.
