Transtibial Powered Prostheses: Single and Dual Actuator Configurations
摘要
The actuator-derived powered prosthesis configuration enables a diversity of contextually specified applications. Current configurations incorporate single and dual actuator strategies. These types of powered prostheses satisfy mission specific objectives. Single actuator powered prosthetic designs generally enable powered plantar flexion and actuator established control of the prosthetic ankle–foot complex. Another unique single actuator powered prosthesis emphasizes dorsiflexion control primarily enabling toe clearance during swing phase. With the trend toward miniaturization, dual actuator configuration powered prostheses are now feasible. These powered prostheses provide more biomimetic representation as the ankle–foot complex is inherently segmented. Dual actuator powered prostheses have been demonstrated to provide further advances respectively of lifestyle activity opportunities.
