Relationship of footwear comfort, selected size, and lower leg overuse injuries among infantry soldiers

Background High rates of musculoskeletal injuries such as plantar fasciitis and stress fractures have been observed among physically active military personnel. During service time, infantry soldiers use issued boots daily that should fit well and provide comfort to prevent injuries and decrease lower extremity pain effectively. The association of military boot comfort with overuse injuries remains unclear. This study investigates the relationship between the chosen military boot size, perceived boot comfort and lower leg overuse injury. Methods During the cross-sectional study, 227 (males, n = 213; females, n = 14) active-duty infantry soldiers at a mean age of 29.5 years old, and with an average service time of 7.2 years were assessed for a history of overuse injury, footprint length, appropriate shoe size, and footwear comfort. Males with a history of overuse injury (n = 32) and non-injured age-matched controls (n = 34) were selected for detailed testing and establishing the possible relationship between footwear comfort and lower leg overuse injury. Results No relationship was found between footwear comfort and a history of lower leg overuse injury. N = 38 (57.6%) of study subjects were wearing an inappropriate shoe size daily. Inappropriate shoe size usage affected footwear comfort ratings significantly. Conclusions Study results showed that improper boot size was significantly related to comfort ratings but was not associated with a history of lower leg overuse injury.

RETRACTION: Open reduction internal fixation versus minimally invasive percutaneous fixation for calcaneus fractures: Mid-term outcomes and social consequences

Objectives: This study aims to evaluate the mid-term clinical, functional, radiological, and socioeconomic outcomes of calcaneus fractures treated with open reduction-internal fixation (ORIF) versus minimally invasive percutaneous fixation (MIPF). Patients and methods: A total of 48 patients (34 males, 14 females; mean age: 44.05 years; range, 19 to 64 years) who underwent either ORIF or MIPF for calcaneus fractures between January 2010 and January 2016 were retrospectively analyzed. The patients were divided into two groups as the ORIF group (n=36) and MIPF group (n=12). The American Orthopaedic Foot & Ankle Society (AOFAS) score, Maryland Foot Score (MFS), and the Short Form-36 (SF-36) scores were assessed for the clinical assessment. The mean duration of operation, mean length of hospitalization, pedobarographic gait analysis, the incidence of contralateral knee pain, increased shoe size, and change of profession due to significant heel pain were also evaluated. The Böhler’s angle, Gissane angle, and calcaneal varus were measured for radiological assessment. Results: There was a significant difference in the mean operation time (p=0.001) and length of hospitalization (p=0.001) between the two groups. There was no significant difference between the pre- and postoperative third-year Böhler’s and Gissane angles (p=0.05, p=0.07, p=0.09, respectively). There were no significant differences between the postoperative first-, second-, and third-year AOFAS, MFS, and SF-36 scores (p=0.57, p=0.55 p=0.85, p=0.64, p=0.21, p=0.51, p=0.20, p=0.15, p=0.22, respectively). Thirteen patients in the ORIF group and five patients in the MIPF group changed their job due to significant heel pain. The increased shoe size was correlated with the residual calcaneal varus (p=0.001). Conclusion: Both methods have pros and cons in the treatment of calcaneal fractures. Although MIPF is more advantageous in terms of operation duration and length of hospitalization, more favorable radiological results can be obtained with ORIF. Calcaneal varus should be corrected to prevent the increased shoe size and contralateral knee pain.

COMPARATIVE CHARACTERISTICS OF FOOT LENGTH AND SHOE SIZE IN MALE AND FEMALE ADOLESCENTS LIVING IN DIFFERENT GEOGRAPHICAL ZONES

The purpose of the study is to compare the length of the left and right feet, as well as the shoe size in 19 year old adolescents living in different geographical zones. Foot-measuring device was used to measure the length of the foot in 222 people living in various regions of Belarus and the Southern Urals. We assessed the size of shoes worn by girls and boys. The study was conducted at the same period of day in the interval from 12.00 to 13.00, in the same microclimate conditions (room temperature +20 C, relative humidity – 51%, air velocity – 0, 2 m/s. The findings obtained show an increase in the length of the foot in 19 year old girls compared to the average values in this age group. The girls living in the Grodno region had a 0.47 cm longer foot than the girls living in the Brest region and 0.5 cm longer than girls living in the Minsk region. There are differences in the size between the left and right feet for the girls living in the Grodno and Brest regions: for girls from the Grodno region, the difference is 0.04 cm, and for girls living in the Minsk region – 0.02 cm. The average foot length of 19-year-old girls living in the Grodno region of Belarus differs significantly (p<0.05) from the foot length of girls in the Southern Urals. The difference makes up 1.5118 cm of the right foot and 1.6384 cm of the left foot. The feet in the residents of the Brest region (right 1, 1330 cm, left-1, 1616 cm) is longer than that of 19-year-old girls in the Southern Urals. The difference in foot length between girls from the Minsk region and the southern Urals is 1, 0358 cm for the right foot, and 1, 0814 cm for the left. The feet of boys living in Belarus is longer than that of the boys from the Southern Urals for the right foot by 0.7921 cm and for the left foot by 0.8957 cm. 19-year-old residents of the Grodno region wear shoes of a larger size than the girls of the same age from the Southern Urals.

A Simple Foot Plantar Pressure Measurement Platform System Using Force-Sensing Resistors

Generally, there are two types of working style, i.e., some people work in sitting conditions, and the remaining work mostly in a standing position. For people working in a standing position, they can spend hours in a day doing their work standing. These people do not realize that it can cause medical issues, especially for the feet, namely biometric problems. In addition, several doctors in Indonesia are already aware of this issue and state that the biometric problems faced by those kinds of people can be predicted from the load distribution on the foot. However, the tool used by the doctors in Indonesia to measure biometric problems is not a digital tool. Therefore it is very difficult to measure and predict the biometric problems quantitatively. This study aims to develop a low-cost static load measuring device using force-sensing resistor (FSR) sensors. The measuring instrument is designed in the form of a pressure plate platform which consist of 30 FSR 402 sensors. The sensors are placed right underneath the display area of the foot, 15 sensors on the soles of the left and right feet. Ten students from the Department of Mechanical Engineering, Diponegoro University (five men and five women) were asked to stand on the platform. Each subject also measured foot length (FL) to estimate shoe size, foot area contact (FAC) for validation between genders, and foot type using the digital footprint tools. From the results of measurements obtained for the left foot in the medial mid foot area, i.e., in sensors 5 and 7, not exposed to the load, on almost all subjects except subject number 3 with a load of 0.196 kg on sensor 7. The highest average load occurs in the heel area i.e., sensor 1 measured 0.713 kg and the smallest average load occurs in the five sensors, with 0 kg. A static load gauge that is designed to be used to measure each leg area for subjects with a shoe size of 40–42 with low price to be held in hospital-orthopedic hospitals and biomechanical research centers.

Does the shoe really fit? Characterising ill-fitting footwear among community dwelling older adults: an observational cross-sectional study

Background : Falls in older people are common and can result in loss of confidence, fear of falling, restriction in activity and loss of independence. Causes of falls are multi-factorial. There is a paucity of research assessing the footwear characteristics among older people who are at high risk of falls, internationally and in the Irish setting. The aim of this study was to examine the proportion of older adults attending a geriatric day hospital in Ireland who were wearing incorrectly sized shoes. Methods : A consecutive sample of 111 older adults aged 60 years and over attending a geriatric day hospital in a large Irish teaching hospital was recruited. Demographic data including age, mobility, medications, co-habitation status, footwear worn at home and falls history were recorded. Shoe size and foot length were measured in millimetres using an internal shoe gauge and SATRA shoe size stick, respectively. Participants’ self-reported shoe size was recorded. Footwear was assessed using the Footwear Assessment Form (FAF). A Timed Up and Go (TUG) score was recorded. Functional independence was assessed using the Nottingham Extended Activities of Daily Living (NEADL) Scale. The primary outcome of interest in this study was selected as having footwear within the suggested range (10 to 15mm) on at least one foot. Participants who met this definition were compared to those with ill-fitting footwear on both feet using Chi-square tests, T-tests or Mann–Whitney U tests. Results : The mean difference between shoe length and foot length was 18.6mm (SD: 9.6mm). Overall, 72% of participants were wearing footwear that did not fit correctly on both feet, 90% had shoes with smooth, partly worn or fully worn sole treading and 67% reported wearing slippers at home. Participant age, TUG score and NEADL score were not associated with ill-fitting footwear. Conclusions : Wearing incorrectly fitting shoes and shoes with unsafe features was common among older adults attending geriatric day services in this study. A large number of participants reported wearing slippers at home.

Does the shoe really fit? Characterising ill-fitting footwear among community dwelling older adults: an observational cross-sectional study

Background Falls in older people are common and can result in loss of confidence, fear of falling, restriction in activity and loss of independence. Causes of falls are multi-factorial and include extrinsic factors such as unsafe footwear. Inappropriate footwear may increase the risk of falls. There is a paucity of research assessing the footwear characteristics among older people who are at high risk of falls, internationally and in the Irish setting. The aim of this study was to examine the proportion of older adults attending a geriatric day hospital in Ireland who were wearing incorrectly sized shoes. Methods A consecutive sample of 111 older adults aged 60 years and over attending a geriatric day hospital in a large Irish teaching hospital was recruited. Demographic data including age, mobility, medications, use of glasses, social support, footwear worn at home and falls history were recorded. Shoe size and foot length were measured in millimetres using an internal shoe gauge and SATRA shoe size stick, respectively. Subjects’ self-reported shoe size was recorded. Footwear was assessed using the Footwear Assessment Form (FAF). A Timed Up and Go (TUG) score was recorded. Participation was assessed using the Nottingham Extended Activities of Daily Living (NEADL) Scale. Those with shoes fitting on at least one foot were compared to those with ill-fitting footwear on both feet using Chi-square tests, T-tests or Mann–Whitney U tests. Results 72% of participants were wearing footwear that did not fit correctly on both feet according to our definition based on previous literature. Only 6% were wearing footwear that fitted correctly on both feet. 67% wore slippers at home. 90% had shoes with smooth, partly worn or fully worn sole treading. Participant age, TUG score and NEADL score were not associated with ill-fitting footwear. Conclusions Wearing incorrectly fitting shoes and shoes with unsafe features is common among older adults attending geriatric day services. The large number of participants who reported wearing slippers at home is also an important finding. Ill-fitting footwear and slippers are risk factors for falls thus warranting further investigation to help guide future falls prevention services at day hospitals.

Static electronic baropodometry in patients with metatarsalgia

Objective: To analyze the values obtained by electronic baropodometry in patients with metatarsalgia. Methods: A retrospective observational study of medical data (gender, height, weight, body mass index, foot laterality, shoe size and clinical diagnosis) and values obtained by static electronic baropodometry (load distribution and maximum and mean pressure) was performed. A total of 39 patients with clinical complaints of metatarsalgia were selected and subjected to static electronic baropodometry. Results: Female gender was more prevalent (58.9%) among patients, and 61.53% of the patients were overweight or obese. The mean maximum pressure was 1.76kgf/cm2, and the forefoot-to rearfoot load distribution ratio was 0.86. There was a significant correlation between body mass index and maximum pressure. No correlation was found with shoe size. Conclusion: The baropodometry values measured in this study were similar to those reported in the literature. Obese and overweight patients had a higher maximum pressure value, which suggests a higher risk of metatarsal pain in this population. Level of Evidence III; Diagnostic Studies; Study of non consecutive patients; Without consistently applied reference “gold” standard.
