There are no known studies on the changes in walking ability in patients with transfemoral amputations returning to daily activities after prosthetic gait training. The ability to walk after discharge may vary depending on an individual’s physical, psychological, and social factors. This study compared spatiotemporal variables and lower limb coordination ability at the end of training and one year after the end of training in seven unilateral transfemoral amputees and analyzed the factors affecting walking ability. The study results confirmed that there was no significant difference in spatiotemporal parameters such as walking speed and lower limb coordination ability after one year of training, and walking ability was well maintained after training. Five out of seven (71.4%) participants in this study returned to work, and there was a strong correlation between employment and gait improvement (r = 0.806, p < .05). In conclusion, activities such as social participation, employment, and exercise were very important factors in maintaining and improving an individual’s walking ability. The findings are intended to be used as basic data to provide guidelines for maintaining the health of lower limb amputees.

The number of amputees is increasing globally due to various accidents or diseases such as diabetes. Among them, there are many patients with upper limb amputations, especially those with hand or finger amputations. As a result, it is highly possible that many people need prosthetic limbs. Most of the prosthetic limbs currently commercialized are products that implement only models without function. Additionally, prosthetic limbs, which have been actively studied in recent years, have many sensors and actuators, providing excellent capabilities inperforming various tasks. However, it is difficult for partial amputees such as finger amputations to use because it targets the entire hand under the wrist. Thus, we propose to develop a wearable finger that can be used by patients with partially amputated fingers. This paper designs the structure of the wearable finger prosthesis and performs the dynamic modeling of the linkage used in the structure. Also, simulation using RecurDyn software is conducted to estimate motion and contact force.
