The present invention relates to the field of disease tracking and potentially even diagnostics. Specifically, it relates to a method of assessing a muscular disability and, preferably, spinal muscular atrophy (SMA) in a subject comprising the steps of determining at least one performance parameter from a dataset of pressure measurements of the individual finger strength from said subject using a mobile device, and comparing the determined at least one performance parameter to a reference, whereby the muscular disability and, preferably, SMA will be assessed. The present invention also relates to a mobile device comprising a processor, at least one pressure sensor and a database as well as software which is tangibly embedded to said device and, when running on said device, carries out the method of the invention as well as the use of such a device for assessing a muscular disability and, preferably, SMA.本發明係關於疾病追蹤及甚至可能診斷之領域。明確言之，本發明係關於一種評估一對象之肌肉失能及較佳地脊髓性肌肉萎縮症(SMA)之方法，該方法包括以下步驟：使用一行動裝置從來自該對象之個別手指力量之一壓力量測資料集判定至少一個效能參數，及比較該經判定至少一個效能參數與一參考，藉此將評估該肌肉失能及較佳地SMA。本發明亦係關於一種行動裝置，其包括一處理器、至少一個壓力感測器及一資料庫以及軟體，該軟體有形地嵌入至該裝置且在於該裝置上運行時實行本發明之方法以及使用此一裝置用於評估肌肉失能及較佳地SMA。
