Table 2 Subjective feedback of the participants

From: Evaluation of new suspension system for limb prosthetics

Subject no. Subject’s preference Mobility grade Subjective feedback
1 Seal-In 1 K4 He did not feel any pain at the distal of his residual limb with the Seal-In and the new suspension system during walking. He experienced more confidence and also stated that the Seal-In was more suitable than the other suspension systems. While removing the prosthesis was more challenging, he preferred to use the seal-in system.

2 Seal-In 4 K3 He was more satisfied with the silicone liners compared to the PTB with Pelite liner. After changing to silicone liner (TSB socket), he did not have pain at the distal end of the residual limb, and the wound was healed after two weeks. He felt more confident with the silicone liner and different lock systems (pin/lock, magnet or HOLO). Among the four systems in this study, he preferred the HOLO, the magnetic system, and the pin/lock system.

3 Seal-In 4 K3 He did not feel any pain at the distal of residual limb with the seal-in and the new suspension system. However, he had pain during donning and doffing with the seal-In liner. He stated that the seal-in was more suitable during walking, but wearing and removing the prosthesis was extremely more difficult compared to the other suspension systems.

4 Seal-In 4 K2 It was very difficult to use the seal-In due to upper limb weakness; he preferred the hook and loop, pin/lock and magnetic systems mostly due to easy donning and doffing.

5 Seal-In 4 K2 He did not feel pain with the seal-in and the new suspension system. Nevertheless, he preferred the new suspension system due to its advantages of easy donning and doffing. He was not happy with the tearing noise during doffing the prosthesis.

6 Seal-In 4 K3 Pain at the end of the socket was less with the TSB socket compared to the PTB socket. He was satisfied with the pin/lock, hook/loop and magnetic systems while he felt more socket fit and less rotation inside the socket with the seal-in. He mentioned that he is not going to use the seal-in due to the difficulty in donning and doffing.

7 Seal-In 3 K3 He felt more socket fit and higher confidence with the seal-in during walking but he was not satisfied with the donning and doffing procedures. He preferred to use the pin/lock and magnetic systems. He was not happy with the hook/lop system due to the sound developed during doffing the prosthesis.

8 Seal-In 4 K3 He was happier with the pin/lock and HOLO systems due to easy donning and doffing procedures. Also, he felt less traction at the end of the socket with HOLO and seal-in system.

9 Seal-In 4 K2 He felt more comfortable at the distal end with the seal-in and the new suspension system, and he was more confident during walking. Regarding the donning and doffing, he preferred the pin/lock and HOLO system. He chose the pin/lock as his first choice due to easy donning and doffing.
