Article Snippet: Walsh et al. (2011) [ ] , To assess the validity and reliability of a portable quantitative balance measurement technology compared to the force plate (the gold standard) Cohort: 2 participants (1M, 29; 1F, 22) , AMTI (Advanced Mechanical Technology) force plates Tactex high density (HD) pressure sensor mat SHIMMER IMU sensor (used for syncing pressure sensor and force plate systems) Participant stands on pressure mat wearing IMU sensor , • The two Berg Balance Scale (BBS) estimates of each participant in successive trials, using lasso model with automatic segmentation of data, have a mean absolute error of 1.44 points • The proposed technique predicts accurate functional balance of the elderly people and has the potential to act as a surrogate of BBS test. However, the cohort is too small, only 2 participants , • Portable alternative to a force plate system means there is potential for remote use • Laptop is used to collect data and needs trained professional to operate, making system appropriate for community care or use in care facilities • Additional IMU unit required for syncing adds complexity to the setup.
