Table 4 Summary of outcome measures

From: The effects of a strength and neuromuscular exercise programme for the lower extremity on knee load, pain and function in obese children and adolescents: study protocol for a randomised controlled trial

Primary outcome parameters Instrument for data collection
 Overall peak external frontal knee moment and impulse 3D gait analysis during walking
Secondary outcome parameters
 Frontal and sagittal kinematics and kinetics for hip, knee and ankle joints 3D gait analysis during walking and stair climbing
 KOOS subscales (Austrian-German version) Knee function in daily living (ADL)
Knee function in sport and recreation (Sport/Rec)
Knee-related quality of life (QOL)
Knee pain and other symptoms
 Changes of function and strength of the targeted muscle groups Physical examination/orthopaedic status
 Adherence to training programme Percentage of completed sessions among the number of intended exercise sessions
 Ratings of knee-related pain 7-point ordinal scale (followed for the duration of the intervention)
Other outcome parameters
 Cardiopulmonary testing Symptom-limited cardiopulmonary exercise testing on a cycle ergometer
 Anthropometry Anthropometric measurements
 Body composition Bioimpedance analysis
 Nutritional status 24-hour recall method (daily, self-reported consumption of food-intake)
 Psychological status AD-EVA test inventory, Child Behaviour Checklist (CBCL/4-18 )
 Blood samples Growth hormones (GH, IGFBP3, AP) and inflammation (procalcin, TGF-α, IL-8) from venous blood samples
All measures will be recorded at baseline and follow-up unless stated otherwise
