IRGL self-reported pain. Pain severity (VAS) QoL (VAS)
QoL seven question sum score
Activity restriction, ROM
Muscle strength
Observed activity restrictions
Healthcare utilisation, lifestyle behaviour, BMI
Significant MANOVA effects were found for pain, QoL, quadriceps, BMI, physically active lifestyle, and visits to the physical therapist. Most effects were moderate at post-test assessment and smaller at follow-up. No effects were found for range of ROM or functional tasks

IRGL self-reported disability, VAS pain in the past week Observed disability, Drug use NSAIDs/paracetamol, Global perceived effect, muscle strength & ROM hip, knee, physical activity At 24 weeks exercise treatment was associated with a small to moderate effect on pain during the past week (difference in change between the two groups −11.5 (95 % CI −19.7 to −3.3). At 36 weeks no differences were found between groups.

AIMS2-SF QoL, lower body, upper body, symptom & social. IPAQ physical activity, BMI, prescriptions. Health service utilisation Compared with the control group, for intervention group II, significant changes in the AIMS2-SF dimensions social (p < 0.001), symptom (p = 0.048), and lower body (p = 0.049) were identified. Radiographs (P = 0.031) and orthopaedic referrals (p = 0.044) decreased whereas prescriptions of pain relievers increased significantly.
