The Effect of Prosthetic Limb Sophistication and Amputation Level on Self-reported Mobility and Satisfaction With Mobility.
Daniel C Norvell, Alison W Henderson, David C Morgenroth and 4 others
PMID 38561145WHAT IT FOUND
Prosthesis sophistication affects mobility and satisfaction differently by amputation level.
For transtibial amputees, higher sophistication improved satisfaction but not advanced mobility. For transfemoral amputees, higher sophistication improved advanced mobility but not satisfaction.
Key findings
01For transtibial amputees, intermediate sophistication was associated with higher mobility satisfaction compared to basic, but not with achieving advanced mobility.
02For transfemoral amputees, intermediate sophistication was associated with nearly 10 times the odds of achieving advanced mobility compared to basic, but not with mobility satisfaction.
03Advanced sophistication showed no significant association with mobility satisfaction for either amputation level.

What it does not show
The study population was exclusively Veterans, who may have different access to prosthetic components than the general population. There were very few female participants. The sample size for transfemoral amputees was small, leading to wide confidence intervals and less precise estimates for this group. The study did not account for baseline mobility status, socket fit, or alignment, which can influence outcomes. A 21% response rate for patient-reported outcomes may introduce selection bias, although participants were similar to non-participants.
Declared interests
The study was supported by the U.S. Government, non-Public Health Service funding. No specific commercial conflicts of interest were reported in the provided text.
The easy way to misread this
Do not assume that more sophisticated prostheses universally improve both mobility and satisfaction. The benefits are specific to amputation level: intermediate components improved satisfaction for transtibial patients but mobility for transfemoral patients, and advanced components did not significantly improve satisfaction for either group.
