简要总结
This randomized controlled trial aims to investigate the effects of neuromuscular and Pilates exercise programs compared with a control group in young adults with dynamic knee valgus (DKV). Thirty-six participants were randomly assigned to neuromuscular, Pilates, or control groups. The intervention groups completed a supervised exercise program three times per week for six weeks (18 sessions).
The primary outcome is the frontal plane projection angle (FPPA) during single-leg tasks. Secondary outcomes include muscle strength, balance, and vertical jump performance.
详细描述
This prospective, single-blind randomized controlled trial was designed to evaluate the comparative effects of Pilates and neuromuscular exercise training on lower extremity alignment and postural control in young adults with dynamic knee valgus (DKV). Ethical approval was obtained from the Istanbul Atlas University Non-Interventional Scientific Research Ethics Committee (Approval No: E-22686390-050.99-41964, 03/05/2024).
A total of 45 participants aged 18-24 years, all right-leg dominant, were initially enrolled and randomized into three groups: Pilates, neuromuscular exercise, and control (15 in each group). Randomization was performed using computerized allocation. Due to dropouts, 36 participants (12 per group) completed the study between June and August 2024.
The interventions consisted of a 6-week supervised program (18 sessions, 3 times per week). Both Pilates and neuromuscular protocols were progressive in intensity, incorporating resistance bands, core stabilization, and functional balance exercises. The control group did not receive any intervention but underwent the same baseline and post-intervention assessments.
The primary outcome was the frontal plane projection angle (FPPA) during single-leg squat and single-leg drop jump tasks, measured using 2D video analysis.
The secondary outcomes included:

研究组 & 干预措施
Pilates Exercise Group
Participants in this group completed a 6-week supervised Pilates exercise program, with 18 sessions. The program included mat-based and resistance band exercises focusing on core stabilization and postural alignment.
干预措施: Pilates Exercise Program (Behavioral)
Neuromuscular Exercise Group
Participants in this group performed a progressive neuromuscular training program for 6 weeks, with 18 supervised sessions. The program emphasized balance, proprioception, dynamic stability, and strengthening of lower extremity muscles.
干预措施: Neuromuscular Exercise Program (Behavioral)
Control Group
Participants in this group did not receive any exercise intervention during the 6-week period. They underwent the same baseline and post-intervention assessments as the experimental groups but continued with their usual daily activities.
结局指标
主要结局
Frontal Plane Projection Angle (FPPA)
时间窗: At baseline (Day 1) and following completion of 6 weeks of intervention (Week 6)
Participants performed a single-leg vertical drop jump from a 20 cm platform with the dominant leg while keeping their hands on the waist. Knee valgus angle at landing was recorded using 2D video analysis with a camera placed 3 m in front at a height of 45 cm.
次要结局
- Isometric Strength of Gluteus Medius(At baseline (Day 1) and following completion of 6 weeks of intervention (Week 6))
- Isometric Strength of Rectus Femoris(At baseline (Day 1) and following completion of 6 weeks of intervention (Week 6))
