“…In this current study, dyslipidaemia, hypertension, and abdominal obesity were the most prevalent metabolic variables—all of which have been associated with reduced gait velocity in older adult populations. Ashan et al (2023) reported reduced gait velocity in hypertensive older adults compared to normotensive older adults ( 16 ), and a recent longitudinal study reported a greater rate of yearly decline in gait velocity with hypertensive patients compared to normotensive patients ( 17 ). In addition, the negative effects of obesity have been clearly demonstrated in adults.…”

BackgroundThe association between poor gait and functional movement ability and metabolic syndrome (MetS) has been well established in older adults. A continuous cardiometabolic risk score, MetSindex, may more easily identify individuals at risk for cardiometabolic disease who do not yet meet the stringent criteria for a formal MetS diagnosis. Although the association between MetS and gait velocity is well established in older adults, no such relationship has been identified in younger adults; a group experiencing a rapid increase in the development of MetS.MethodsMetSindex was determined for 21 young adults using standard procedures. Gait velocity was measured as participants completed a ten-meter walk test. Spatiotemporal parameters of gait were also derived using a motion capture system. Simple linear regression was used to determine the relationship between MetSindex and gait velocity, as well as MetSindex and spatiotemporal parameters of gait.ResultsThere was a large inverse relationship between MetSindex and gait velocity. A large inverse relationship was also observed between MetSindex and cadence, and a large positive relationship was observed between stance time and double limb support time.ConclusionsGait velocity slows in young adults who do not necessarily meet the criterion for positive diagnosis of MetS—but demonstrate an increased risk for MetS and cardiovascular disease through higher MetSindex scores. The mechanism underlying reduced gait velocity may be fewer, but not shorter steps. Determining easy-to-use surrogates of MetS (e.g., gait velocity) may help combat the growing prevalence of MetS by increasing access to preventative approaches.

“…Gait is a functional rhythmical movement, and complex fluctuations of unknown origin appear in the normal pattern among healthy individuals [14,15]. Although significant variation of gait is most often observed in movement disorders [16], few studies have looked at changes in the coefficient of variation of gait parameters (variability) as a risk factor or as a result of an injury [17]. Psoriatic arthritis patients showed higher stride variability [18], while patients with traumatic brain injury had increased step width variability [19].…”

Footwear usage could be a promising focus in reducing musculoskeletal injury risk in lower extremities commonly observed among the military. The goal of this research was to find potential gait-related risk factors for lower leg overuse injuries. Cases (n = 32) were active-duty infantry soldiers who had suffered an overuse injury in the previous six months of service before enrolling in the study. The control group (n = 32) included infantry soldiers of the same age and gender who did not have a history of lower leg overuse injury. In the gait laboratory, individuals were asked to walk on a 5-m walkway. Rearfoot eversion, ankle plantar/dorsiflexion and stride parameters were evaluated for barefoot and shod conditions. Barefoot walking was associated with higher stride time variability among cases. According to the conditional regression analysis, stride time variability greater than 1.95% (AUC = 0.77, 95% CI (0.648 to 0.883), p < 0.001) during barefoot gait could predict lower leg overuse injury. Increased barefoot gait variability should be considered as a possible predictive factor for lower leg overuse injury in the military, and gait with military boots masked stride-related differences between soldiers with and without lower leg overuse injury.

“…Several studies have reported an association between lower extremity injuries and military boots ( Gait is a cyclic movement, and in healthy individuals, whether they are soldiers or civilians, complex fluctuations of unknown origin arise in the typical pattern (Hausdorff et al, 1995;Winter, 1984). Although significant variation in gait parameters is most observed in movement disorders (Ahsan et al, 2023), few studies have examined changes in gait variability as a risk factor or as a result of an injury among the military (Strongman & Morrison, 2020). Further research is required to promote evidence-based strategies that could minimise MSKI in the military across countries, and to establish medical gait and foot screening guidelines.…”

Biomechanical Aspects of Military Footwear Usage and their Relationship with Lower Extremity Overuse Injuries. Doctoral Thesis

Professional military service involves high-intensity physical training, including field training exercises and marching, which increase the risk of musculoskeletal injuries (MSKIs). In the military, MSKIs represent a significant medical concern, leading to an increased financial strain on military healthcare and a decrease in military preparedness. Acute and overuse lower extremity MSKIs are more common in the knee, lower leg, and foot. The role of military footwear in the development of overuse injuries is currently unresolved, and more research is suggested on the relationship between military footwear and overuse injuries. The purpose of this work was to determine the incidence of overuse MSKI in the lower and investigate its possible relationship with military footwear usage among the Latvian Land Forces. The research was carried out on infantry soldiers during their annual medical examinations at the Military Medical Support Centre of the Latvian National Army Logistic Command from 2018 to 2020. In a cross-sectional study on the epidemiology of MSKI, a total of n = 227 active duty infantry soldiers participated. Among study participants, 42.7 % had a history of lower extremity injuries, with a higher prevalence of overuse injuries in the lower leg. Study participants who wore inappropriate size of military boots reported lower comfort ratings for all parameters, irrespective of their history of injuries. Gait analysis was performed barefoot and wearing military boots during the case-control study (n = 66) where subjects were divided into groups according to their history of overuse injuries. Both groups showed an elevation in the foot contact angle, while simultaneously showing a reduction in the eversion of the rearfoot and the angular velocities of the ankle when wearing military footwear. The conditional logistic regression model revealed that stride time variability (OR = 2.71, 95 % CI 1.31 – 5.60) during barefoot gait demonstrated statistical significance in predicting the risk of lower leg overuse injury. The optimal threshold for stride time variability was determined to be 1.95 %, which could effectively predict the occurrence of lower leg overuse injuries, showing a sensitivity of 56 % and a specificity of 88 %. Based on research findings, walking in military footwear improves stability and encourages gait symmetry, and the risk of overuse injuries to the lower extremities does not appear to be influenced by gait with footwear. The research results support the importance of further investigating gait variability as a possible risk factor for MSKI and lay the groundwork for the establishment of guidelines for medical gait and foot screening in the military. The Doctoral Thesis was developed at the Rehabilitation Research Laboratory of Rīga Stradiņš University and the Latvian National Army Logistic Command Military Medical Support Centre Defence: at the public session of the Promotion Council Basic Medicine on 2 April 2024 at 10.00 remotely via online platform Zoom. 3.1 Basic Medicine; Sub-Sector – Medical Biomechanics.
