Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Supervised progressive strength training with elements like (SNG)
Participants will be randomized to SNG and perform training sessions (60-70 minutes) twice weekly, over 12 weeks, commencing 8 exercises for the lower extremities in 3 sets of 10 repetitions with an intensity of 12 repetitions maximum. Individual progression, quality of exercise, number of sets, repetitions, and additional training weights will be monitored and adjusted throughout the intervention period by experienced physiotherapists
Supervised progressive strength training including elements of neuromuscular exercise intervention (SNG)
Participants will be randomized to SNG and will perform training sessions (60-70 minutes) twice weekly, over a duration of 12 weeks, commencing 8 exercises for the lower extremities in 3 sets of 10 repetitions with an intensity of 12 repetitions maximum. Individual progression, quality of exercise, number of sets, repetitions, and additional training weights will be monitored
home based low-intensity weight-bearing exercise protocol
Participants allocated to CON will receive written and verbal instructions regarding 4 home-based (low-intensity), weight-bearing exercises for the lower extremities, to be performed twice weekly. This intervention is designed to resemble usual care in cases where persistent knee muscle strength deficits would be discovered and considered a clinical issue.
