[PMID: 36219599 PMCID: PMC9553044 DOI: 10.1371/journal.pone.0275178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 09/12/2022] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Low-dye taping (LTD) is widely used by athletes and medical practitioners but the research regarding its impacts on athletic performance is lacking. This study investigated the effects of using low-dye taping on plyometric performance and muscle activities in recreational basketball players with overpronated feet. METHODS Twelve collegiate males with at least three years basketball training experience and navicular drop (ND) value ≥10 mm performed the navicular drop, drop jump and countermovement jump tests. Surface electromyography of selected lower limb muscles were observed during bilateral free squat. All tests in non-taped (NT) and taped (TAP) conditions were counterbalanced using repeated crossover study design. Paired t-test with an alpha level of 0.05 and non-clinical magnitude-based decision (MBD) with standardized effects were used to analyze data. RESULTS Contact time and reactive strength index (RSI) in the TAP condition were significantly shorter (p = 0.041) and higher (p<0.01) than the NT condition respectively. No significant difference in CMJ performance between NT and TAP was observed. MBD demonstrated clear effects on both ND (standardized effect: -1.54±0.24), flight time (standardized effect: 0.24±0.30), contact time (standardized effect: -0.27±0.21), RSI (standardized effect: 0.69±0.35) and eccentric activities of inferior gluteus maximus (standardized effect: 0.23±0.35), gluteus medius (standardized effect: 0.26±0.29) and tibialis anterior (standardized effect: 0.22±0.06). CONCLUSIONS LDT is effective in correcting overpronated feet by increasing ND height. Meanwhile, it provides a small increase in RSI and gluteal muscle activity during the eccentric (down) phase of the bilateral squat, and without affecting CMJ performance. Conditioning coaches or therapists may use LDT to enhance gluteal activation for reducing injury occurrence and reactive strength performance in drop jump tasks.

Abstract
PURPOSE This cross-sectional study aimed to investigate the effects of foot arch deformities on physical characteristics, muscular strength, and motor function in older women depending on the presence or absence of pain. METHODS Overall, 145 community-dwelling women aged 65 to 90 years were included in this study. We measured the foot arch height ratio (AHR, dorsal height/truncated foot length) and classified participants with AHR values above, below, or within 1.5 standard deviations into the high-arched group (HAG), Low-Arched Group (LAG), or normal-arched group (NAG), respectively. We also compared body characteristics (age, height, weight, body mass index (BMI), and skeletal mass index), muscle strength (handgrip strength and intrinsic foot strength (IFS)), and locomotive function (two-step value and gait speed) among the three groups. RESULTS Locomotive examination and muscle strength showed significant differences among the three groups only in the presence of pain; in the two-step test, HAG, NAG, and LAG values were 0.98 cm/cm, 1.19 cm/cm, and 1.18 cm/cm, respectively. The IFS measured 19.2 N, 24.2 N, 31.0 N, respectively, in the HAG, NAG, and LAG. CONCLUSION This study suggests that decreased IFS affects the mobility function of high-arched feet in older women. Although there was no significant difference in the evaluation of pain, HAG showed the highest average value, which is considered to contribute to the decreased two-step value. It has been suggested that a high-arched foot in the presence of pain is associated with IFS weakness and may affect the decline of mobility function in older women.

Abstract
Objective To investigate effects of taping techniques on arch deformation in adults with pes planus. Methods The following databases were searched up to March 2020, including Web of Science, Pubmed, EBSCO, CNKI and Cochrane Library. Heterogeneity and publication bias were assessed by I2 index and funnel plots, respectively. In addition, Cochrane scale was used to evaluate the quality of research. Results Navicular height for three antipronation taping techniques significantly increased immediately post tape compared with baseline (mean difference = 4.86 mm, 95% CI = 2.86–6.87 mm, Z = 4.75, p < 0.001). The highest increase was observed in Augmented low-Dye (ALD). Modified low-Dye (MLD) was second only to ALD (p<0.001). Navicular height after walking for 10 min was much higher than baseline (p<0.001), with MLD decreased smaller than ALD. Conclusions ALD was the most effective taping technique for controlling foot arch collapse immediately post tape compared with baseline, followed by MLD. By contrast, MLD could possibly performed better than ALD in maintaining immediate navicular height after walking for 10 min. Low-Dye could make resting calcaneal stance position closer to neutral position. Although positive effects of Navicular sling, low-Dye and Double X taping interventions were observed, they could not maintain this immediate navicular height effect after a period of higher intensity weight-bearing exercise.

Abstract
Background Kinesio Tape® (KT) is an elastic therapeutic tape that is applied to the skin for treatment of sport-related injuries. Its application has been purported to facilitate the neuromuscular system, thus altering skeletal muscle activity to increase joint range of motion and improve performance. Due to its proposed therapeutic effect, KT may benefit individuals with excess foot pronation in order to decrease pain and improve function. Unfortunately, current research regarding the ability of KT to alter foot biomechanics is limited. Purpose The purpose of this study was to determine if the application of KT to the ankle and lower leg would alter static foot posture, plantar pressure, and foot motion during walking in individuals with foot pronation. Study Design Prospective Cohort Study. Methods Thirty participants (10M/20F) were recruited for this study. Each participant had their dorsal arch height and midfoot width measured prior to the application of the KT. In addition, their dynamic rearfoot eversion and plantar pressure was recorded during walking using an electrogoniometer and plantar pressure system. After these measurements were collected, KT was applied to their right foot and lower leg in order to attempt to facilitate activity in the posterior tibialis muscle. After applying the tape, the above measurements were repeated. Results None of the variables measured were statistically significantly different between the pre-test and post-test. Conclusion Application of KT did not result in a change in static foot posture, plantar pressure, and frontal plane rearfoot motion during walking. As such, KT cannot be recommended as a treatment for reducing excessive foot pronation where such a goal would be beneficial. Level of Evidence Level 3.

Abstract
OBJECTIVES To develop a clinical prediction rule (CPR) to identify patients with plantar heel pain (PHP) likely to benefit from biomechanical anti-pronation taping (BAPT). DESIGN A prospective cohort study. SETTING An outpatient rehabilitation department in a general hospital. PARTICIPANTS Seventy-five patients with PHP. MAIN OUTCOME MEASURES After completing a series of physical examinations, all patients received BAPT and were evaluated with a numeric rating scale for pain intensity, the patient-specific functional scale and foot function index (FFI) for function, and the global rating of change for perceived improvement. RESULTS Twenty-eight patients achieved a successful outcome. A CPR with 6 significant variables was identified by a multivariate logistic regression: FFI score less than 33.3, hip adduction angle of the most affected side was greater than the contralateral side, ankle plantarflexors and hip abductors on the most affected side were not weaker than those on the contralateral side, ankle invertors on the most affected side were weaker than the contralateral side, and having more than 2 painful sites in the low back and lower extremity regions. If 5 or more of the 6 predictors were presented, the probability of success increased from 37% to 80%. CONCLUSIONS A CPR has been developed to identify patients with PHP likely to benefit from BAPT.

Abstract
Medial tibial stress syndrome (MTSS) is one of the most common exercise-induced leg pain. The navicular drop (ND) was identified as a risk factor for MTSS. This study aimed to evaluate the short-term effects of sports taping applied to the supporting lower leg during sitting, standing, walking, and jogging to restrict the ND in healthy elite athletes.Twenty-four healthy elite athletes without a history of exercise-induced pain or injuries in the lower limbs participated in this study (median age: 21.00 years; 1st--3rd quartiles; 19.25-22.00). The 4 taping conditions were used: rigid taping (RT), kinesiology taping (KT), placebo taping (PT), and non-taping (NT). The order of taping techniques was randomly assigned. Normalized navicular height (NH), ND, and normalized ND evaluated using 3-dimensional motion analysis, and normalized peak plantar pressure (PP) were compared in 4 taping conditions during sitting, standing, walking, and jogging.During sitting, the normalized NH of RT is higher than that of NT, KT, and PT (χ = 17.30, P = .001), while during jogging, the normalized NH of RT is higher than that of NT and PT (χ = 10.55, P = .014). The normalized peak PP of NT is higher than that of PT (χ = 8.871, P = .031) in the lateral midfoot region.This study showed the RT technique maintained NH during sitting and jogging, and the RT technique could be an effective preventive and treatment strategy for MTSS.

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.

Abstract
[Purpose] The purpose of the present study was to examine the effects of toe-spread (TS) exercises and hip external rotator strengthening exercises for pronated feet on lower extremity muscle activities during stair-walking. [Subjects and Methods] The participants were 20 healthy adults with no present or previous pain, no past history of surgery on the foot or the ankle, and no foot deformities. Ten subjects performed hip external rotator strengthening exercises and TS exercises and the remaining ten subjects performed only TS exercises five times per week for four weeks. [Results] Less change in navicular drop height occurred in the group that performed hip external rotator exercises than in the group that performed only TS exercises. The group that performed only TS exercises showed increased abductor hallucis muscle activity during both stair-climbing and -descending, and the group that performed hip external rotator exercises showed increased muscle activities of the vastus medialis and abductor hallucis during stair-climbing and increased muscle activity of only the abductor hallucis during stair-descending after exercise. [Conclusion] Stair-walking can be more effectively performed if the hip external rotator muscle is strengthened when TS exercises are performed for the pronated foot.

Abstract
CONTEXT Arch tapings have been used to support the arch by increasing navicular height. Few researchers have studied navicular height and plantar pressures after physical activity. OBJECTIVE To determine if taping techniques effectively support the arch during exercise. DESIGN Crossover study. SETTING Athletic training research laboratory. PATIENTS OR OTHER PARTICIPANTS Twenty-five individuals (13 men, 12 women; age = 20.0 ± 1.0 years, height = 172.3 ± 6.6 cm, mass = 70.1 ± 10.2 kg) with a navicular drop of more than 8 mm (12.9 ± 3.3 mm) volunteered. INTERVENTION(S) All individuals participated in 3 days of testing, with 1 day for each tape condition: no tape, low dye, and navicular sling. On each testing day, navicular height and plantar pressures were measured at 5 intervals: baseline; posttape; and after 5, 10, and 15 minutes of running. The order of tape condition was counterbalanced. MAIN OUTCOME MEASURE(S) The dependent variables were navicular height in millimeters and plantar pressures in kilopascals. Plantar pressures were divided into 5 regions: medial forefoot, lateral forefoot, lateral midfoot, lateral rearfoot, and medial rearfoot. Separate repeated-measures analyses of variance were conducted for each dependent variable. RESULTS Navicular height was higher immediately after application of the navicular-sling condition (P = .004) but was reduced after 5 minutes of treadmill running (P = .12). We observed no differences from baseline to posttape for navicular height for the low-dye (P = .30) and no-tape conditions (P = .25). Both the low-dye and navicular-sling conditions increased plantar pressures in the lateral midfoot region compared with the no-tape condition. The low-dye condition created decreased pressure in the medial and lateral forefoot regions compared with the no-tape condition. All changes were identified immediately after application and were maintained during running. No changes were noted in plantar pressures for the no-tape condition (P > .05). CONCLUSIONS Both taping techniques effectively changed plantar pressures in the lateral midfoot, and these changes were sustained throughout the 15 minutes of exercise.

Abstract
PURPOSE/BACKGROUND No evidence exits regarding the magnitude of the change in foot posture following the "modified reverse-6" (MR6) taping procedure, either alone or in combination with the "low-dye" (LD) taping technique. The purpose of this study was to investigate the change in the height and width of the midfoot after application of the MR6 and the MR6 plus the LD (MR6+LD) taping technique and determine how long those changes last. METHODS Eleven individuals (2 female and 9 male) were recruited for this study and were tested under each of two experimental conditions, the MR6 and the MR6+LD taping technique. The order of testing for the two conditions was randomly determined. For each condition, the height and width of the midfoot at 50% of each subject's foot length was initially measured and then again immediately following the application of the tape. These measurements were repeated four hours later immediately prior to running two miles on a treadmill, again immediately after running, and finally after another four hours. RESULTS The dorsal arch height increased significantly with both the MR6 and MR6+LD taping, but only the MR6+LD remained statistically greater after four hours, a bout of exercise and again at the end of the day. The mean width of the midfoot significantly decreased with both taping procedures. The change in the width of the midfoot remained significantly decreased in both taping conditions after exercise and throughout the day. CONCLUSIONS Both taping procedures are able to significantly change the height and width of the medial longitudinal arch of the foot, but the change lasted longer when the two taping procedures were combined.

Abstract
Positional faults are considered a possible underlying mechanism mimicking the symptoms of a joint sprain. Despite numerous clinical studies indicating the presence of positional faults, there is limited evidence of imaging studies confirming positional faults. This case report is a preliminary study that offers clinical and ultrasonographic evidence of a proximal positional fault of the radius, treated successfully with manual therapy techniques. Three weeks after a bike fall on the outstretched hand, the patient in this study presented with right wrist pain and a lack of progress with conventional conservative treatment (NSAIDs, rest and immobilization). Clinical findings indicating a proximal positional fault of the radius included pain during active pronation increased by associating a passive movement of the radius in a proximal direction and it was reduced by associating a passive movement of the radius in a distal direction. Ultrasonographic (US) images showed a reduction of radio-capitellar distance on the right side (11.4 mm) compared to the left side (13.3 mm). A positive response with a distal mobilization of the radius supported the proximal positional fault of the radius. After two manual therapy sessions, the patient had recovered normal asymptomatic function. The outcomes used to assess function and pain were active pronation range of motion, the Spanish version of the DASH questionnaire and a 0-10 numeric pain rating scale. Each measure was conducted prior and after each treatment session and one week post treatment. The patient was re-examined at 6 months follow-up, during which US images, demonstrated a normalization of the right radio-capitellar distance.

Abstract
STUDY DESIGN Case-control. OBJECTIVES The specific aim of this study was to examine the association between abnormal foot arch postures and a history of shoulder or elbow surgery in baseball pitchers. BACKGROUND Pitching a baseball generates forces throughout the musculoskeletal structures of the upper and lower limbs. Structures such as the longitudinal arch of the foot are adaptable to stresses over time. Repeated pitching-related stresses may contribute to acquiring abnormal foot arch postures. Inversely, congenitally abnormal foot arch posture may lead to altered stresses of the upper limb during pitching. METHODS A convenience sample of 77 pitchers was recruited from a Division I university team and a professional baseball franchise. Subjects who had a history of shoulder or elbow surgery to the pitching arm were classified as cases. Subjects who met the criteria for classification of pes planus or pes cavus based on longitudinal arch angle were classified as having abnormal foot arch posture. Odds ratios were calculated to examine the association between abnormal foot arch posture and pitching-arm injury requiring surgery. RESULTS Twenty-three subjects were classified as cases. The odds of being a case were 3.4 (95% confidence interval: 1.2, 9.6; P = .02) times greater for subjects with abnormal foot arch posture and 2.9 (95% confidence interval: 1.0, 8.1; P = .04) times greater for subjects with abnormal foot posture on the lunge leg. CONCLUSION Abnormal foot arch posture and a surgical history in the pitching shoulder or elbow may be associated. Because the foot and its arches are adaptable and change over time, the pathomechanics of this association should be further explored.

An important question regarding the use of taping is whether it can be applied consistently from one therapist to the next, from one session to the next or from one day to the next. Thus, the purpose of this study was to determine whether the "modified" Reverse-6 taping procedure using elastic tape could be applied to produce a consistent within-day and between-day change in the height and width of the medial longitudinal arch for a single clinician as well as between clinicians. A second purpose was to determine if the amount of general clinical experience influenced this consistency. METHODS Fifteen asymptomatic individuals (10 female and 5 male) with a mean age of 28.7 years were recruited to participate in this study. The height and width of the midfoot at 50% of each subject's foot length was measured in standing using a digital gauge and caliper. These measurements were done twice on the same day, on two different days and again by two clinicians with different levels of experience before and after having their feet taped using the "modified" Reverse-6 taping technique using elastic tape. Both clinicians received a one-hour training session on how to apply the taping technique and were also given a DVD showing the technique that they could review. In addition to descriptive statistics, intra-class correlation coefficients (ICC) were used to assess each clinician's within-day and between-day reliability. Between-clinician reliability was also determined. RESULTS The mean dorsal arch height and midfoot width before the application of tape was 62.7 and 78.9 mm. The mean dorsal arch height and width after the application of tape was 66.6 and 78.8 mm. The within-day reliability ICC(2,1) values for the two clinicians ranged from .865 to .991. The between-day reliability ICC(2,1) values for the two clinicians ranged from .874 to .985. The between-clinician reliability ICC(2,1) values ranged from .918 to .993. CONCLUSIONS The results of this study indicate that the "modified" Reverse-6 foot taping technique using elastic tape can be used by more than one therapist for the same patient as well as from one session to the next with excellent reliability. LEVEL OF EVIDENCE Level 2, Prospective Cohort Study.

One-week time course of the effects of Mulligan's Mobilisation with Movement and taping in painful shoulders. ACTA ACUST UNITED AC 2013; 18:372-7. [PMID: 23391760 DOI: 10.1016/j.math.2013.01.001] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2012] [Revised: 12/29/2012] [Accepted: 01/04/2013] [Indexed: 11/20/2022]
Abstract
Previous research suggests that Mulligan's Mobilisation-with-Movement (MWM) technique for the shoulder produces an immediate improvement in movement and pain. The aims of this study were to investigate the time course of the effects of a single MWM technique and to ascertain the effects of adding tape following MWM in people with shoulder pain. Twenty-five participants (15 males, 10 females), who responded positively to an initial application of MWM, were randomly assigned to MWM or MWM-with-Tape. Range of movement (ROM), pressure pain threshold (PPT) and current pain severity (PVAS) were measured pre- and post-intervention, 30-min, 24-h and one week follow-up. Following a one-week washout period, participants were crossed over to receive a single session of the opposite intervention with follow-up measures repeated. ROM significantly improved with MWM-with-Tape and was sustained over one week follow-up (p < 0.001; 18.8°, 95% confidence intervals (CI) 7.3-30.4), and in PVAS up to 30-min follow-up (38.4 mm, 95% CI 20.6-56.1 mm). MWM demonstrated an improvement in ROM (11.8°, 95% CI 1.9-21.7) and PVAS (40.4 mm, 95% CI 27.8-53.0 mm), but only up to 30-min follow-up. There was no significant improvement in PPT for either intervention at any time point. MWM-with-Tape significantly improved ROM over the one-week follow-up compared to MWM alone (15.9°, 95% CI 7.4-24.4). Both MWM and MWM-with-Tape provide a short-lasting improvement in pain and ROM, and MWM-with-Tape also provides a sustained improvement in ROM to one-week follow-up, which is superior to MWM alone.

Abstract
BACKGROUND The low-Dye technique serves to limit hindfoot pronation and medial arch collapse. Few studies exist that investigate the effects on medial arch deformation from a biomechanical perspective. METHODS Kinematic data was collected using a Motion Analysis System. Foot function of 21 healthy adults was assessed during the stance phase of gait. Subjects were evaluated prior to and immediately following the low-Dye tape application, as well as at 48 h. Foot deformation was assessed during the stance phase of gait using the calcaneus, navicular and 1st metatarsal head markers to calculate the medial longitudinal arch angle (MLA) and the dynamic arch height index (dAHI). Paired t-tests were used to assess low-Dye tape effectiveness. RESULTS There was a significant 19.3% reduction in MLA immediately after application of the tape. However only 4.01% reduction remained in deformation after 48 h. The MLA deformation findings were consistent with the AHI change, showing a significant change in the arch deformation between Pre and Post0 low-Dye taping. The effects were short-lived. CONCLUSIONS There are measurable changes to medial arch height and amount of arch height deformation during gait following low-Dye taping. Although changes were present immediately after application, results were diminished 48 h after application.

Abstract
OBJECTIVE To determine the effects of augmented low-dye (ALD) taping and a heel-pain orthosis (HPO) on pain, peak plantar pressure (PPP), and mean plantar pressure (MPP) while walking and jogging. DESIGN Cross-over study design. SETTING University clinical laboratory. PARTICIPANTS Seventeen physically active or sedentary individuals with plantar fasciitis. INTERVENTIONS Both PPP and MPP were evaluated after 45 seconds of walking and jogging during the 3 interventions (control, ALD, HPO) under 4 areas of the foot: lateral rearfoot and forefoot, and medial rearfoot and forefoot. Pain was assessed during each intervention (at 60-second mark) using the visual analog scale (VAS). MAIN OUTCOME MEASURES Peak plantar pressure, MPP, and VAS. RESULTS The ALD produced a decrease in walking MPP (44.66 ± 14.46) under the lateral rearfoot compared with the control (57.92 ± 22.18; P = 0.024) and in jogging MPP (55.05 ± 18.27) compared with the control (67.22 ± 20.95; P = 0.002) and HPO (68.51 ± 17.57; P = 0.002). Scores of VAS decreased with the application of HPO (7.12 ± 10.08; P < 0.002 and 12.15 ± 15.61; P < 0.003) and ALD (6.24 ± 5.71; P < 0.006 and 10.09 ± 8.87; P < 0.001) while walking and jogging when compared with the control (17.32 ± 17.86 and 26.65 ± 22.38). CONCLUSIONS Although the HPO and ALD produced statistically and clinically decreased VAS scores while walking and jogging, further research is needed beyond these preliminary findings to determine long-term outcomes related to pain relief.

Abstract
Several studies have already reported that specific foot/ankle muscle reinforcement strategies induced strength and joint position sense performance enhancement. Nevertheless the effects of such protocols on sprint performance and plantar loading distribution have not been addressed yet. The objective of the study is to investigate the influence of a 5-wk foot/ankle strength training program on plantar loading characteristics during sprinting in adolescent males. Sixteen adolescent male athletes of a national training academy were randomly assigned to either a combined foot/ankle electromyostimulation and resistance training (FAST) or a control (C) group. FAST consisted of foot medial arch and extrinsic ankle muscles reinforcement exercises, whereas C maintained their usual training routine. Before and after training, in-shoe loading patterns were measured during 30-m running sprints using pressure sensitive insoles (right foot) and divided into nine regions for analysis. Although sprint times remained unchanged in both groups from pre- to post- training (3.90 ± 0.32 vs. 3.98 ± 0.46 s in FAST and 3.83 ± 0.42 vs. 3.81 ± 0.44 s in C), changes in force and pressure appeared from heel to forefoot between FAST and C. In FAST, mean pressure and force increased in the lateral heel area from pre- to post- training (67.1 ± 44.1 vs. 82.9 ± 28.6 kPa [p = 0.06]; 25.5 ± 17.8 vs. 34.1 ± 14.3 N [p = 0.05]) and did not change in the medial forefoot (151.0 ± 23.2 vs. 146.1 ± 30.0 kPa; 142.1 ± 29.4 vs. 136.0 ± 33.8; NS). Mean area increased in FAST under the lateral heel from pre- to post- (4.5 ± 1.3 vs. 5.7 ± 1.6 cm(2) [p < 0.05]) and remained unchanged in C (5.5 ± 2.8 vs. 5.0 ± 3.0 cm(2)). FAST program induced significant promising lateral and unwanted posterior transfer of the plantar loads without affecting significantly sprinting performance. Key pointsWe have evaluated the effects of a foot/ankle strength training program on sprint performance and on related plantar loading characteristics in teenage athletes, and this have not been examined previously.Our results showed no significant pre- to post- changes in sprint performance.This study revealed initially a lateral transfer and secondly a posterior transfer of the plantar loads after the foot/ankle strength training program.

Abstract
STUDY DESIGN Case-control and reliability study. OBJECTIVES To compare foot and ankle characteristics between individuals with and without patellofemoral pain syndrome (PFPS) and to identify reliable weight-bearing foot and ankle measurements for use in future research on PFPS. BACKGROUND PFPS is a common presentation to sports medicine and orthopaedic clinics. Characteristics of the foot and ankle are often linked with PFPS development, although evidence to support this link is equivocal and there is a lack of consensus on how best to evaluate these characteristics. METHODS A variety of weight-bearing foot and ankle measurements were evaluated by 3 raters of varying experience in 20 individuals with PFPS and 20 controls matched by age, sex, height, and body mass. Between-group comparisons were made for each measurement using data from an experienced podiatrist blinded to group assignment of the participants. Intrarater and interrater reliability was compared between all measurements using the first 15 participants from each group. RESULTS Between-group comparisons showed that the individuals in the PFPS group had a more pronated foot posture when assessed by the foot posture index and longitudinal arch angle, and for all measurements relative to subtalar joint neutral. Foot posture index, normalized navicular drop, and calcaneal angle relative to subtalar joint neutral measurements also possessed high reliability in both groups when used by experienced raters. Reliability was not influenced by rater experience or the presence of PFPS for relaxed-stance foot posture measurements. Both tester inexperience and the presence of PFPS reduced reliability for all measurements of foot posture relative to subtalar joint neutral and measurement of weight-bearing ankle dorsiflexion. CONCLUSION The foot posture index, normalized navicular drop, and calcaneal angle relative to subtalar joint neutral are all reliable and sensitive to group differences when used in a population with PFPS. Individuals with PFPS possess a more pronated foot posture and increased foot mobility compared to controls. Prospective evaluation of these measurements is now required to determine whether they contribute to the development of PFPS.

Abstract
The frequent occurrence of flexible flatfoot raises the question of its pathologic status. There may be cultural overtones resulting in the consideration that flat feet are always pathologic. Parents may believe that their own flat feet were successfully treated when they were children and wish the same for their offspring. Few studies attempt to answer the question of the natural history of this condition. This article reviews the available literature dealing with the natural history, comorbidities, recommendations for treatment, expansion of biomechanical theory, and classification of flatfoot. Issues associated with imaging of flatfoot and the design of studies to validate the effects of treatment are also reviewed.

Abstract
BACKGROUND Although extreme values of arch height have been associated with increased risk for overuse injury, knowledge is limited regarding the association between arch height and plantar pressure distributions during gait. The primary purpose of this study was to explore which plantar pressure measurements during gait were associated with static arch height and arch height index. METHODS Static arch height, arch height index, and dynamic plantar pressure distributions were collected for 1000 subjects (566 males, 434 females, 30.6 [SD 8.0] years, 171.1 [SD 9.3]cm, 76.9 [SD 14.7]kg). A hierarchical regression analysis was performed to determine the most parsimonious set of plantar pressure parameters associated with arch height. The predicted values were used to calculate dynamic arch height index. Correlation and residual analysis were performed to assess the association between statically and dynamically determined arch height indices. FINDINGS A 5-variable model (F = 296.6; P < 0.001) was able to describe the relationship between static arch height and the dynamic foot during gait (R =0 .77 [95% CI = 0.75-0.80]). The correlation between the static and dynamically determined arch height indices was r = 0.60 (95% CI = 0.53, 0.63), with a mean residual of 0.000 (SD 0.015). INTERPRETATION A multivariate model generated by plantar parameters during gait was able to predict 60% of the variability in static arch height. This model consisted of variables that appear to be clinically plausible and inform the association between static arch height and dynamic foot posture. Future researchers should address the association between statically and dynamically determined AHI values with lower extremity overuse injuries.

Abstract
In order to determine if the use of antipronation taping could be used to direct foot orthoses prescription, seven high school athletes with lower extremity or foot pain caused by overuse stress were taped for 3 days during practice sessions. A visual pain scale and the Foot and Ankle Ability Measure sports subscale were used to monitor pain and function improvement caused by taping. If the taping was effective, foot orthotics were fabricated and posted according to the change in foot posture created by the tape. After wearing the foot orthotics for 4 weeks, all athletes reported a substantial short-term (4-week) reduction in pain and an increase in function. The results of this case series indicate that changes in foot posture created by taping can be used to guide foot orthosis prescription.

Abstract
Athletes with persistent anterolateral ankle discomfort may have developed sinus tarsi syndrome (STS). Sinus tarsi syndrome develops from excessive motions of the subtalar joint that results in subtalar joint synovitis and infiltration of fibrotic tissue into the sinus tarsi space. Physical therapists treating athletes with ankle conditions should examine the talocrural and subtalar joints for signs of hypermobility as injuries can affect both of these important articulations of the lower extremity. Localized ankle discomfort to the sinus tarsi space and feelings of instability with pronation and supination movements of the subtalar joint will help identify STS. Intervention for this condition will focus on enhancing subtalar joint stability and function of the lower extremities. The purpose of this clinical commentary is to discuss the etiologies and signs of STS and describe the components of an intervention plan appropriate for athletes with STS.

Abstract
OBJECTIVE The purpose of this study was to determine the arch height ratio in a large cohort of subjects as well as to assess the reliability and validity of the foot measurements utilized in the study. METHOD Eight hundred and fifty subjects, 393 women and 457 men, consented to participate in the study. The dorsal arch height, total foot length, and the truncated foot length were used to calculate two variations of the arch height ratio. In addition to determining within- and between-rater measurement reliability, radiographs were used to establish validity. RESULTS The truncated arch height ratio can be estimated using the total foot length, unless toe deformities are present in the individual being assessed. All foot measurements had high levels of intra- and inter-rater reliability and the validity of measuring the dorsal arch height while standing with equal weight on both feet was established. CONCLUSIONS This investigation provides normative values from a large cohort of healthy female and male subjects for two variations of the arch height ratio. The arch height ratio is a reliable and valid measurement that may prove useful to clinicians and researchers for the classification of foot posture.

Abstract
BACKGROUND Low-dye (LD) taping is commonly used to reduce rearfoot pronation. No studies have previously investigated the effectiveness of LD taping using both plantar pressure distribution (F-Scan) and 3-D (CODA) analysis of rearfoot motion. METHODS 20 healthy subjects with a navicular drop test exceeding 10 mm participated in the study. T tests were used to determine whether significant (p < 0.05) differences in plantar pressure and rearfoot motion occurred with LD taping. RESULTS LD taping resulted in statistically significant increases in peak plantar pressure in the lateral midfoot (p = 0.000), along with significant decreases in pressure in the medial forefoot (p = 0.014), and the medial (p = 0.000) and lateral hindfoot (p = 0.007). No significant changes occurred in the medial midfoot (p = 0.794) or lateral forefoot (p = 0.654). When assessed using motion analysis, taping resulted in a statistically significant decrease in rearfoot pronation (p = 0.006), supination (p = 0.025) and total rearfoot range of motion (p = 0.000). The mean rearfoot position during stance was not significantly different however (p = 0.188). CONCLUSION LD taping is associated with alterations in peak plantar pressure in the midfoot and forefoot that indicate reduced pronation with LD taping. However, LD taping appears to reduce both pronation and supination in the rearfoot, rather than simply reducing pronation, when assessed using 3D motion analysis. Therefore, it would appear that LD taping does indeed reduce pronation, by restricting rearfoot motion in general, rather than pronation specifically. The degree of change observed with LD taping was however very small, and further research is needed to clarify the clinical significance of these initial findings.

Abstract
PURPOSE : To evaluate the initial effects of antipronation taping (APT) on foot posture and electromyographic (EMG) activity of tibialis anterior (TA), tibialis posterior (TP), and peroneus longus (PL) muscles during walking. METHODS : Five asymptomatic individuals who exhibited lower medial longitudinal arch height on a clinical assessment of gait walked on a treadmill for 10 min before and after the application of an APT technique-specifically, the augmented low-Dye. Arch height (AH) in standing as well as peak and average amplitude, duration, time of onset, and time of offset of recorded EMG activity during walking were analyzed for each condition. RESULTS : APT produced a mean (95% confidence interval (CI)) increase in AH of 12.9% (6.5-19.3; P = 0.005). Mean (95% CI) reductions in peak and average EMG activation of TA (peak: -23.9% (-34.0 to -13.9); average: -7.8% (-13.6 to -2.0)) and TP (peak: -45.5% (-77.3 to -13.7); average: -21.1% (-41.6 to -0.6)) were observed when walking with APT (P < 0.05). The APT also produced a small increase in duration of TA EMG activity of 3.7% (0.9-6.5) of the stride cycle duration, largely because of an earlier onset of EMG activity (4.4%; -8.1 to -0.8 of a stride cycle; P < 0.05). CONCLUSION : APT reduces activity of the TA and TP muscles during walking while increasing AH, which provides preliminary evidence of its role in reducing the load of these key extrinsic muscles of the ankle and the foot. Follow-up study is required to evaluate these findings.

Abstract
CONTEXT Taping and orthoses are frequently applied to control excessive foot pronation to treat or prevent musculoskeletal pain and injury of the lower limb. The mechanism(s) by which these devices bring about their clinical effects are at best speculative and require systematic evaluation. OBJECTIVE To determine the initial effect of the augmented low Dye taping technique (ALD) on plantar foot pressures during walking and jogging. DESIGN Within-subjects, repeated-measures randomized control trial. SETTING Gait research laboratory. PATIENTS OR OTHER PARTICIPANTS Fifteen women and 7 men with an average age of 28.0 +/- 7.4 years who were asymptomatic. INTERVENTION(S) Participants walked and jogged along a 12-m walkway before and after the application of ALD. The untaped side served as the control. MAIN OUTCOME MEASURE(S) Peak and mean maximum plantar pressure data were calculated for the medial and lateral areas of the rear and midfoot and the medial, central, and lateral forefoot areas. Thus, a 3-factor model was tested: condition (ALD, control) x time (preapplication, postapplication) x area (medial and lateral rearfoot and midfoot and medial, central, and lateral forefoot). RESULTS Significant 3-way interactions were present for both peak and mean maximum plantar pressure during walking (F (6,126) = 9.55, P = .006 and F (6,126) = 11.36, P = .003, respectively) and jogging (F (6,126) = 5.76, P = .026 and F (6,126) = 4.56, P = .045, respectively) tasks. The ALD predominantly increased plantar pressures in the lateral midfoot during walking and jogging. In addition, tape reduced mean maximum pressure at the medial forefoot and at the medial rearfoot during walking. CONCLUSIONS The ALD, which has previously been shown to reduce excessive pronation, produced significant increases in lateral midfoot plantar pressures, thereby providing additional information to be considered when the mechanism(s) of action of such a treatment are modeled.
