rope is wrapped 21/2 times around said pulley. In operation, the pulley is running freely during hoisting and offers little resistance. In descending, however, the pulley is blocked by the return stop, and the rope slides over the surface of the pulley. The resulting friction takes up the greater part of the load suspended on the rope.
Furthermore, an emergency stop for the rope is often provided on the load the of the pulley. Essentially, said rope stop senses the running speed of the rope particularly in the descending direction. In the case of an excessive speed, the rope stop is released and directly blocks the rope.
However, in practice, the known hoisting/lowering apparatus of this type cause a considerable wear of the rope by overcrossing windings on the pulley,or not the episode disturbed the patient\'s sleep (episodes of nocturia) were recorded; the time of rising from and going to bed were also recorded. Efficacy analyses included mean and median changes from baseline to endpoint in the number of each of the following per 24 h: episodes of urgency, incontinence, nocturia and micturitions. The volume voided per micturition was also recorded. Patients without at least one on-treatment efficacy assessment were excluded from the analyses. In line with ICS guidelines for the presentation of data, symptom 'resolution'/'normalisation' rates were also examined, as well as an assessment of the 50% improvement in the symptoms of urgency, incontinence, number of micturitions and nocturia ([@b13]). Symptom 'resolution' was defined as the complete absence of symptoms at the study endpoint that were
