Using motion analysis and electromyography, the findings suggest that free ankle motion may improve load symmetry during sit-to-stand, but not during lifting. These results highlight that free prosthetic ankle motion could enhance load symmetry during specific functional movements, suggesting that its effectiveness may depend on the type of activities.<\/span><\/div>\n<div dir=\"auto\">\n<p>&nbsp;<\/p>\n<div dir=\"auto\"><\/div>\n<div dir=\"auto\">\n<div dir=\"auto\"><span><img loading=\"lazy\" decoding=\"async\" class=\"\"
