Fig 1 The Strathclyde Upper-Limb Activity Monitor (SULAM) and data logger (left) and the SULAM being worn by participant (right). The SULAM was attached to the outer aspect of both upper limbs along the following reference points: acromion process, lateral epicondyle, and lateral border of the radius.

Fig 2 Result of classification of movement and range. (A) The output signal from the SULAM when an able-bodied participant is performing different task (abbreviations: A, drinking; B, eating; C, combing hair; D, answering telephone). The signal from the SULAM can depict the upper-limb activity as the movement and position of the wrist with respect to the shoulder. (B) The result of classification of movement (M) and nonmovement (NM). (C) The result of classification of range. Note that only those samples classified as movement were considered for the classification of range. Abbreviations: above-S, movement above shoulder position; below-MT, movement below midtrunk position; upper-T, movement between midtrunk position and shoulder position.

Fig 3 (A) Equality plot of total movement time and (B) maximum displacement above shoulder position. There was a significant difference in the total movement time between arms for both groups (able-bodied: P=.000; stroke: P=.000). The equality line indicates values where there is the same movement time for both upper limbs.
