An occupational therapist (OT) will incorporate participants' preference, goals, and current function to co-create UL exercise activities with participants. The exercise activities will be based on real-life activities that participants are familiar with. During the 6-week TeleRehab period, participants will complete 30 one-hour sessions of UL exercise activities, on their own without immediate supervision.

An occupational therapist (OT) will incorporate participants' preference, goals, and current function to select UL exercise activities with participants from the RehabKit program software. During the 6-week TeleRehab period, participants will complete 30 one-hour sessions of UL exercise activities, on their own without immediate supervision.

Participants will self-initiate rehabilitative activities through the HAHE program.

Participants will be seated at a table, face a rectangular box that is divided into two square compartments of equal dimensions on the left and right sides by means of a partition. At the beginning of the test, 150 1-inch blocks are in the same compartment. The task is to move as many blocks as possible, one at a time, from one compartment to the other using one arm only.

Participants will be assessed 4 weeks before intervention (Time 1), immediately before (Time 2) and immediately after intervention (Time 3). The investigators will measure the change between Time 1 and Time 2 (baseline change), and the change between Time 2 and Time 3 (treatment change). The outcome measure is the difference between the two changes.

The test quantitatively measures UL motor ability through 15 timed and functional tasks - forearm to table, forearm to box, extend elbow, extend elbow with weight, hand to table, hand to the box, reach and retrieve, lift can, lift pencil, lift paper clip, stack checkers, flip cards, turn key in lock, fold towel, and lift basket.

Participants will be assessed 4 weeks before intervention (Time 1), immediately before (Time 2) and immediately after intervention (Time 3). The investigators will measure the change between Time 1 and Time 2 (baseline change), and the change between Time 2 and Time 3 (treatment change). The outcome measure is the difference between the two changes.

The standardized short forms for adults evaluate anxiety, depression, fatigue, UL function, lower limb function, cognitive function, emotional and behavioral dyscontrol, positive affect and well-being, sleep disturbance, ability to participate in social roles and activities, satisfaction with social roles and activities, stigma, and communication.
