Abstract: An arrangement for practizing walking comprises a treadmill (10) serving as a walking substrate, a harness (14) which may be mounted on a patient (11), a suspension cable (16) connectable to the harness, and a device (19) by which a lifting force of an adjustable magnitude may be applied on the patient (11) through the cable (16) and the harness (14). Said device (19) comprises a pulley (20) around which the cable (16) extends in a bight (41). This pulley (20) is arranged for limited movement in a direction transverse to its rotary axis (22) in order to permit a limited variation of the length of said bight (41). By means of an elastically yieldable force generating means (30), an adjustable force, which is substantially independent of the instantaneous position of said pulley (20), may be applied on the pulley (20) in a direction to cause said bight (41) of the cable (16) to assume its maximum length.
