PERBANDINGAN EFEKTIVITAS STRENGTHENING EXERCISE DAN PROPRIOCEPTIVE TRAINING TERHADAP RISIKO FLAT FOOT PADA SISWA DAN SISWI DI SMP NEGERI 13 KOTA MALANG

Background: Navicular drop is an important indicator for evaluating the stability
of the medial arch of the foot. A high navicular drop value indicates reduced arch
stability, which can lead to musculoskeletal problems, particularly in adolescents
who are active in sports.
Objective: This study aims to identify the most effective intervention method for
improving foot stability and biomechanical function among students at SMP Negeri
13 in Malang City, using the Navicular Drop Test.
Methods: This study employed an observational-analytical design with a
comparative study approach, involving 50 students divided into two groups. One
group performed strengthening exercises, while the other underwent proprioceptive
training for four weeks.
Results: Analysis using the Paired Sample T-Test in the strengthening exercise
group showed a decrease from 14.63 ± 3.26 mm to 12.66 ± 3.32 mm (p = 0.000).
In the proprioceptive training group, the NDT value changed from 15.47 ± 2.89 mm
to 13.93 ± 2.90 mm (p = 0.000). A comparison between the groups using an
independent T-test showed that strengthening exercises resulted in a more
significant reduction (-1.97 ± 0.51 mm) compared to proprioceptive training (-1.54
± 0.46 mm), with a p-value of 0.003.
Conclusion: There is a difference in effectiveness between strengthening exercises
and proprioceptive training, with strengthening exercises being more effective in
reducing the navicular drop test results among male and female students at SMP
Negeri 13 in Malang City.
