ADL | Task description |
|---|---|
Turning door handle - one-handed - standing | A door-handle, mounted on a wooden post at 24 cm high, was fixed at the corner of a foldable crate. Participants were standing with their heels at a taped line at 35 cm from the edge of the table. The door handle was placed right in front of the participants’ affected arm at 25 cm from the edge of the table. Participants turned the door handle down and up with their prosthesis hand. |
Lifting crate - two-handed - standing | Participants were standing with their heels at a taped line at 35 cm from the edge of the table. They lifted a foldable crate of 37 x 25 x 19 cm (length x width x height, total weight 1,54 kg) with both hands from the affected to the unaffected side, over a box of 29 x 29 x 17 cm (length x width x height) that was located in front of the participant, at the edge of the table. Tape signs at 20 cm left and right of the box indicated start and end position of the crate. The crate had to be placed beyond these signs. |
Closing and opening zip - two-handed - standing | Participants were fitted with a custom-made jacket with a zip (22 cm long) at the front, starting at hip height. Participants grabbed the zipper with their prosthesis hand and closed and opened the zip, while supporting the jacket with their unaffected hand. Participants were allowed to pass the zipper with their unaffected hand to their prosthesis hand when grabbing it. |
Lifting object - one-handed - seated | A box of 29 x 29 x 17 cm (length x width x height) was placed in front of the participant, at the edge of the table. A wooden cylinder (7 cm diameter, 14 cm high) was placed 14 cm next to the wooden box and 14 cm from the edge of the table, at the affected side of the participant. The participant grabbed the cylinder at its upper side and placed it on the top of the box, at the marked middle point. |
Stirring into cup - one-handed - seated | A cup filled with water was placed in front of the participant at 25 cm from the edge of the table. Participants picked up the spoon with their prosthesis hand, stirred 5 times, and released the spoon. Participants were allowed to pass the spoon with their unaffected hand to their prosthesis hand when grabbing it. |
Handling cutlery - two-handed - seated | A piece of clay (5 cm long) was placed in front of the participant at 25 cm from the edge of the table. Participants held a fork in their prosthesis hand and a knife in their unaffected hand. From this starting position, participants fixated the clay with the fork, and cut it with the knife. |
