Whole-body angular momentum is influenced by bone-anchored limb use and amputation level during walking.

The study lacked a control group of able-bodied individuals or successful socket users who did not receive bone-anchored limbs. It was a retrospective design with a convenience sample, meaning factors like time since amputation, residual limb length, and prosthesis alignment were not controlled. Only level-surface walking was analyzed, so results may not apply to higher-demand activities like trip recovery or uneven terrain. The text reports a numerical value for the socket prosthesis that appears inconsistent with the stated direction of the finding, requiring verification against the original figures.

The authors received research support from the N.I.H. and non-U.S. government entities. No specific commercial conflicts of interest were declared in the provided text.

Do not interpret the reduced angular momentum as a proven reduction in actual fall rates. The study measured a biomechanical proxy for balance, and the authors explicitly state that future work is needed to confirm that bone-anchored limb use objectively reduces falls.
