Training Induced Reduction of Lower-limb Joint Loads During Locomotion in Obese Children

Not Applicable

Completed

• Conditions: Pediatric Obesity; Lower Extremity Biomechanics
• Interventions: Other: Strength and neuromuscular exercise programme

• Registration Number: NCT02545764
• Lead Sponsor: St. Pölten University of Applied Sciences

Brief Summary

Childhood obesity is one of the most critical and accelerating health challenges throughout the world. It is a major risk factor for developing varus/valgus misalignments of the knee joint. The combination of misalignment at the knee and excess body mass may result in increased joint stress and damage to articular cartilage. A training programme, which aims at developing a more neutral alignment of the trunk and lower limbs during movement tasks may be able to reduce knee loading during locomotion. Despite the large number of guidelines for muscle strength training and neuromuscular exercises that exists, most are not specifically designed to target the obese children and adolescent demographic.

The purpose of this study is to evaluate a training programme which combines strength and neuromuscular exercises specifically designed to the needs and limitations of obese children and adolescents and analyse the effects of the training programme from a biomechanical and clinical point of view.

Primary Outcome Measures

Name	Time	Method
Overall peak external frontal knee moment and impulse	Baseline and 12 weeks	Assessed by 3D gait analysis during walking

Secondary Outcome Measures

Name	Time	Method
Adherence to the training programme	Participants will be followed for the duration of the intervention (12 weeks)	Adherence will be considered as the percentage of actually completed sessions during the intervention period among the number of intended exercise sessions.
Physical examination	Baseline and 12 weeks	Changes of function and strength of the targeted muscle groups will be assessed by a physical therapist. Therefore, a hand-dynamometer to investigate differences in muscle strength will be used.
Knee Injury and Osteoarthritis Outcome Score (KOOS)	Baseline and 12 weeks	The Austria-German version of the Knee Injury and Osteoarthritis Outcome Score will be used to assess the participants' opinion about their knee.
Gait pattern	Baseline and 12 weeks	Kinematics and external joint moments for the sagittal and frontal plane for hip, knee and ankle joints as well as spatio-temporal parameters will be assessed by 3D gait analysis during walking and stair climbing.
Ratings of knee related pain	Participants will be followed for the duration of the intervention (12 weeks)	Ratings of knee related pain will be assessed using a 7-point ordinal scale.
