The effects of gluteus maximus and abductor hallucis strengthening exercises for four weeks on navicular drop and lower extremity muscle activity during gait with flatfoot

Abstract

[Purpose] The purpose of the present study is to examine the effects of abductor hallucis and gluteus maximus strengthening exercises on pronated feet. [Subjects and Methods] The present study was conducted with 18 adults without no history of surgery on the foot or ankle. One group performed both gluteus maximus strengthening exercises and abductor hallucis strengthening exercises, while the other group performed only abductor hallucis strengthening exercises five times per week for four weeks. [Results] The group that performed both gluteus maximus and abductor hallucis strengthening exercises showed smaller values in the height of navicular drop than the group that performed only abductor hallucis strengthening exercises. The muscle activity of the gluteus maximus and the vastus medialis increased during heel-strike in the group that added gluteus maximus exercises, and the muscle activity of the abductor hallucis significantly increased in both groups. [Conclusion] Given the results of the present study, it can be suggested that strengthening the gluteus maximus while also performing exercises to correct the pronated foot is an effective method for achieving normal gait.

The Effects of 12 Weeks of Systematic and Functional Corrective Exercises on Body Posture of Students Suffering From Pronation Distortion Syndrome

“…The results are in line with the results of studies carried out by Lynn et al [39], Daneshpour et al [14], Sulowska et al [40], Young-Mi Goo et al [41], Mahdavi et al [42], and Najafi et al [43]. This compatibility can be explained as these studies have used corrective exercises similar to the exercises used in this study as well as the similar participants.…”

Effect of systematic corrective exercises on the static and dynamic balance of patients with pronation distortion syndrome: A randomized controlled clinical trial study

“…[ 9 ] They reported that the static balance, dynamic balance, and posture of the subjects in the experimental and control groups before corrective exercises were not different, but this trend was reversed after performing the corrective exercises, and the experimental group subjects had a better static balance, dynamic balance and posture compared to the pretest stage and the control group. [ 9 10 38 39 40 ] The reason for this alignment may be the use of the corrective exercises in these studies[ 9 10 ] similar to the exercises applied in the present study. Najafi et al .…”

Randomized Clinical Trial: The Effect of Exercise of the Intrinsic Muscle on Foot Pronation

“…This led to them concluding that the SFE could not be defended as a training method, but that it could improve posture control. According to their conclusion, foot posture was influenced not only by the short plantar muscle, but by a set of anatomic structures (i.e., extrinsic muscle, ligaments, and articulations) [2,36].…”
