Purpose: The purpose of this study was to identify the effect of active foot arch support on the muscles of lower extremity electromyographic activity during squat exercise in persons with pronated foot. Methods: The study subjects were 16 persons with pronated foot. They have no history of surgery in lower extremity and trunk and limitation of range of motion or pain when performing squat exercise. Each subject was measured the navicular drop (ND) to determine the pronated foot. And then the subjects were asked to perform three repetitions of a $90^{\circ}$ knee flexion squat in both conditions which are 1) preferred squat and 2) squat with active foot arch support. Results: Paired t-test revealed that squat with active foot arch support produced significantly greater EMG activities in abductor hallucis (p=0.00), proneus longus (p=0.03) and gluteus medius (p=0.04) than preferred squat. But the EMG activities of tibialis anterior, vastus medialis oblique and vastus lateralis were not showed significantly different between the both squat conditions. Conclusion: The findings of this study suggest that active foot arch support during squat increase the activities of lower extremity muscles which are the abductor hallucis, proneus longus and gluteus medius. Also, the abductor hallucis which is one of the planter intrinsic muscle and peroneus longus play a role in support of the foot arch and active foot arch support induced the increase of the activity of gluteus medius. Therefore active foot arch support can change the lower extremity biomechanics as well as passive foot support such as foot orthotics and taping.

Effectiveness of Arch Support Taping is Subjects With Excessive Foot Pronation: A Meta-analysis

So-yeon Park 한국전문물리치료학회 2019 한국전문물리치료학회지 Vol.26 No.4

Background: An excessive pronated foot is defined as a flattening or complete loss of the medial longitudinal arch. Excessive foot pronation is considered to have high risk factors of overuse injuries in the lower limb. Various treatments have been investigated in attempts to control excessive pronation. Objects: This meta-analysis identifies the effects of an anti-pronation taping technique using different materials. Methods: The electronic databases used include MEDLINE, the Physiotherapy Evidence Database(PEDro), Science Direct, the Korean Studies Information Service System (KISS), the Research Information Sharing Service (RISS), the Korea National Library, and the Korean Medical Database (studies published up to July 31, 2019). The database search used the following keywords: foot drop OR foot arch OR foot pronation OR flat foot (pes planus) AND taping OR support. Eight eligible studies were analyzed to determine the effectiveness of anti-pronation taping in study and control groups. Results: The overall random effect size (Hedges’ g) of the anti-pronation taping technique was 0.147(95% confidence interval [CI]: -.214 to .509). When the effect (Hedges’ g) was compared by the type of tape material, rigid tape (RT; Lowdye taping) was .213 (95% CI: -.278 to .704) and kinesiotape (KT; arch support taping) was -.014 (95% CI: -.270 to .242). Based on this meta-analysis, it was not possible to identify the extent to which anti-pronation taping was effective in preventing navicular drop, improving balance, or changing foot pressure. Only three of the eight eligible studies applied KT on excessive pronated feet, and the outcome measure areas were different to those of the RT studies. The KT studies used EMG data, overall foot posture index (FPI) scores, and rear foot FPI scores. In contrast, the RT studies measured navicular heights, various foot angles, and foot pressure. Conclusion: This review could not find any conclusive evidence about the effectiveness of any taping method for patients with pronated feet. Future studies are needed to develop the anti-pronation taping technique based on the clinical scientific evidence.

Purpose:The purpose of this study was to identify the effect of an arch support taping on navicular drop height and plantar pressure in the subjects with excessive pronated foot for 6 weeks. Methods:The fifteen subjects with the pronated foot group and the fifteen subjects with the normal foot group volunteered for this study. Both groups were applied arch support taping at 3 times a week during 6 weeks. Subjects were assessed navicular drop test to evaluate pronation of subtalar joint and plantar pressure on treadmill for pressure measuring system during walking with a bare foot state at pre- taping, after 3 weeks, and after 6 weeks. A two-way repeated analysis of variance design was used to examine the difference of navicular drop height and plantar pressure in the pronation foot group and the normal foot group. Results:The pronated foot group had significantly decreased both the navicular drop height and the plantar pressure under the medial midfoot than the normal foot group after 6 weeks(p<.01). Conclusions:This study proposed that an arch support taping can be support to lift navicular bone as well as to transfer the foot pressure from medial midfoot to lateral midfoot in individuals with excessive pronated foot.

Gyucheol Shin,Taeyoung Kim,Woochan Chun,Sookyoung Park 한국운동생리학회 2023 운동과학 Vol.32 No.3

PURPOSE: This study aimed to determine the correlations between foot posture features, intrinsic foot muscles (IFMs) thickness, and dynamic postural stability. METHODS: Forty-one male participants were divided into two groups according to quantified foot postures using the Foot Posture Index (FPI-6) scores: the neutral foot group (FPI-6 score: 0 to +5) and the pronated foot group (FPI-6 score: >+6). The IFMs thickness was measured using ultrasound images of the flexor digitorum brevis (FDB), flexor hallucis brevis (FHB), and abductor hallucis muscles. To investigate the association between IFMs thickness and dynamic postural stability, the Biodex Balance System (BBS) was used in a single-leg stance position with both the eyes open and closed. RESULTS: In the BBS tests, the pronated foot group demonstrated significant results in the eyes-closed condition (p<.05). In particular, the differences between the eyes open and closed conditions in postural stability indices were significantly greater in the pronated foot group than in the neutral foot group (p<.05). No significant differences in IFMs thickness between the two groups were observed; however, some subdomains of the FPI-6 demonstrated significant positive correlations with postural stability indices and significant negative correlations with IFMs thickness (p<.05). The talonavicular joint was associated with FDB thickness (R=-0.311). Moreover, the forefoot was correlated with FHB thickness (R=-0.327). CONCLUSIONS: The aforementioned results suggest that dynamic postural stability and IFMs thickness are affected by the foot type. Although no significant differences in IFMs thickness were observed, dynamic postural stability and IFMs thickness reduced as the foot displayed features of pronation. This indicates that postural control ability and IFMs are vulnerable to changes in foot posture

The purpose of this study was to examine the effects of customized foot orthotics during march in combat boots. Four volunteers with normal foot and six volunteers with excessive pronation foot among soldiers on service were fitted with foot orthotics. The Ground reaction forces signal from activity of Pre-After military marching. The marching was performed with a speed of 4.5 km/h. The experiment design for research wes composed two experimentation. The first experiment was to examine the ground reaction forces between normal foot and excessive pronator foot during march. The second experiment was to examine the ground reaction forces between wearing orthotics and no wearing orthotics. These data were analyzed by One-way ANOVA method and paired T-test method of SPSS(windows version 15.0). The result of the study were the maximum vertical impact peak and the maximum vertical loading rate on pronator foot tend to statistically significant increase after march. But the maximum vertical impact peak and the maximum vertical loading rate decrease the customized foot orthotics in volunteers with excessive pronation foot compared to volunteers with normal foot. Clinically, the application of orthotics for the soldiers with excessive pronation foot appears to keep nomal foot function and to decrease loading rate.

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

This study aimed to investigate the influence of walking on crural muscle tone and stiffness in individuals with bilateral pronated foot. This study consisted of 16 healthy male. Subjects were divided into a pronated foot group (n = 8) and a normal foot group (n = 8). The navicular drop test on both foot and muscle tone and stiffness in tibialis anterior muscle, medial gastrocnemius muscle, and peroneus longus muscle of both lower extremities were measured before and after 30 min of walking. In this study, the measured navicular drop test before walking was significantly different between pronated foot group and a normal group(p < .05). After 30 min of walking, significantly, increased medial gastrocnemius muscle stiffness of the non-dominant leg was found in the pronated foot group (p < .05). However, there was no significant difference in medial gastrocnemius muscle stiffness between the two groups (p > .05). Based on this study, pronated foot needs to be managed to prevent the abnormally increased medial gastrocnemius muscle stiffness.

김현욱 ( Hyun-wook Kim ),류영욱 ( Young-uk Ryu ) 대한물리의학회 2018 대한물리의학회지 Vol.13 No.2

PURPOSE: Stroke patients may develop an over-pronated foot, resulting in a lower medial longitudinal arch. This can lead to a structural change of the foot due to deformation of the musculoskeletal system. The purpose of this study was to examine the effects of modified low-dye taping on stroke patients with an excessively pronated foot. The effect of the taping on the foot after light daily activity was also examined. METHODS: The subjects consisted of 21 stroke patients with an excessively pronated foot, as measured by the navicular drop test. First, their navicular heights were measured at a relaxed standing position (measure 1) and while standing in the subtalar neutral position (measure 2). Modified low-dye taping was applied to each subject’s affected foot and the navicular height was then measured for the standing posture (measure 3). Finally, each subject walked around for 10 minutes and the navicular height was measured again (measure 4). RESULTS: Statistical analyses showed that the navicular height value at the relaxed standing position (measure 1) was significantly lower than for the other 3 measurements. That is, the modified low-dye taping was effective in maintaining a subtalar neutral position, even after a 10-minute walk, for stroke patients with an excessively pronated foot. CONCLUSION: The results suggest that modified low-dye taping applied to stroke patients with an excessively pronated foot could be an effective way to place the subtalar joint in a neutral position, and that its effect can be sustained for light daily activities.
