Summary of approaches for evaluation of rehabilitation movements.

Approach	Advantage	Disadvantage	Reference
Discrete movement score approaches	Efficient and achieve high accuracy	Cannot track diverse degrees of functional abilities	[37], [45]—[48], [55], [71], [74], [106], [183], [185]—[187]
Rule-based approaches	Provide multiple performance scores; less computation complexity	New rehabilitation exercises require different rules to be designed	[33]—[36], [49], [50], [61], [62], [73], [126], [127], [156], [182], [191]—[195]
Template-based approaches	Avoid the process of making rules; Can reflect the level of motor ability	Only give a overall score for exercise performance	[39]—[41], [52], [53], [55], [57], [96], [97], [103], [128], [138], [140], [143], [145], [148], [156], [190], [196]
