| The objective of this study is to examine homogeneous amputee populations in Thailand and Vietnam and develop a statistical method by which appropriate socket shapes and sizes are specified to meet the needs of these groups.;Anthropometric measurements were collected from transtibial residual limbs of 15 patients in Thailand and 25 patients in Vietnam. Despite the small sample sizes, it was possible to approximate the measurements with a normal distribution. A principal components analysis indicated that two components could describe the limbs: the first describing a general shape and the second describing slight modifications to that shape. Partitioning the principal component distributions to create three shapes and two sizes per shape with up to three liners to be worn, it was possible to achieve a 36% primary fit and 64% secondary fit in the Thai sample population, and a 36% primary fit%, 56% secondary fit, and 8% tertiary fit in the Vietnam sample: Subsequently, rectification models were applied based on current prosthetic practices and recommendations were made for specific socket dimensions for manufacturing.
