Evaluating the use of a thermoplastic socket in Kenya: A pilot study.

BACKGROUND

Many people with amputations who live in low-resourced settings struggle to access the workshops where qualified prosthetists provide appropriate care. Novel technologies such as the thermoplastic Confidence Socket are emerging, which could help facilitate easier access to prosthetic services.

OBJECTIVES

The objective of this study was to evaluate the satisfaction and the performance of transtibial prosthesis featuring the Confidence Socket.

STUDY

DESIGN

This is a longitudinal repeated-measures design study.

METHODS

A convenience sample of 26 participants who underwent transtibial amputation were fitted with the Confidence Socket. The performance of the socket was evaluated after a follow-up period between 1 month and 6 months using the L test of functional mobility and the amputee mobility predictor. Satisfaction with the prosthesis was measured using the Trinity Amputation and Prosthetic Experience Scales and purposefully designed 7-point Likert scales.

RESULTS

Ten of the 26 participants returned for follow-up. Perceived activity restriction and L test times improved significantly at follow-up, but the self-reported satisfaction with the Confidence Socket was lower at follow-up compared with that after fitting.

CONCLUSIONS

The Amparo Confidence Socket represents a potentially viable alternative to improve access to appropriate prosthesis in Kenya, but some aspects of users' self-reported satisfaction should be further investigated.
