Tasks involved in the Glittre-ADL test. A chair was placed at one end of a corridor, and the patient was instructed to sit down on the chair before beginning the tasks. A bookcase with two shelves was placed at the opposite end of the corridor, and three objects weighing 1 kg each were placed on the shelves. Between the chair and the bookcase, there was an object consisting of two stairsteps. The participant wore a backpack with a certain weight (2.5 kg for women and 5 kg for men). Then, the participant was asked to stand up from the chair and travel towards the shelves, travel up and down the steps towards the other end of the corridor, and move the objects from the highest to the lowest shelf and then from the lowest shelf to the floor. Immediately after that, the individual had to move the objects from the floor to the lowest shelf and then from the lowest shelf to the highest shelf. After finishing these tasks, he/she had to return by climbing up and down the steps and sit on the chair. The participant had to repeat the entire route four more times
