Study: NCT04714047

Intervention type: OTHER
Group type: EXPERIMENTAL
Intervention: Progressive Resistance Training and no booster sessions
Description: An initial 12-week exercise intervention, consisting of 1-hour group sessions of progressive resistance training supervised by a physiotherapist 2 times per week.~The sessions consist of a 10-minute submaximal warm up on an exercise bike followed by 50 minutes of PRT with exercises targeting the muscles of the hip and knee joints; leg press, hip extension, hip abduction, hip flexion and knee extension. The progression will be in line with guidelines provided by the American College of Sports Medicine. The intensity will follow repetition maximum (RM) targets, from 12 RM for the first week towards 8 RM for the last weeks.~After the 12 weeks, this group consists of patients who are randomized to receive no further treatment. For the following 9 months, these patients are given a membership to a fitness center where they are encouraged to continue the same exercise regime.

The intensity will follow repetition maximum (RM) targets, from 12 RM for the first week towards 8 RM for the last weeks.~After the 12 weeks, this group consists of patients who are randomized to receive 4 booster sessions (at 1, 3, 5 and 7 months after termination of the initial 12 week intervention). Additionally, for the following 9 months, these patients are given a membership to a fitness center where they are encouraged to continue the same exercise regime without supervision.

Intervention type: OTHER
Group type: ACTIVE_COMPARATOR
Intervention: Neuromuscular exercise and no booster sessions
Description: An initial 12-week exercise intervention, consisting of 1-hour group sessions of progressive resistance training supervised by a physiotherapist 2 times per week.~The sessions consist of a 10-minute submaximal warm up on an exercise bike followed by 50 minutes of NEMEX training with exercises focused on stability, postural function, postural orientation, lower extremity muscle strength, and functional exercises. Progression is made when an exercise is performed with good sensorimotor control and good quality of the performance and with minimal exertion and adequate control of the movement.~After the 12 weeks, this group consists of patients who are randomized to receive no further treatment. For the following 9 months, these patients are given equipment and encouraged to continue the same exercise regime at home without supervision.
