“…The surfaces were chosen such that the stiffness of two surfaces, PU and SS25, were similar and the percentage of energy loss of SS60 and SS25 were similar as these two physical properties have been shown to improve comfort and to reduce impact loads and injuries (Basford and Smith, 1988;Brodsky et al, 1988;Cook et al, 1985;Schwellnus et al, 1990). The laser scans and the analyses related to the castings clearly showed that mid-foot plantar shapes were significantly different, even though the rear-foot and forefoot were fixed and the same among the three surfaces.…”

Effects of surface characteristics on the plantar shape of feet and subjects’ perceived sensations

Orthotics and other types of shoe inserts are primarily designed to reduce injury and improve comfort. The interaction between the plantar surface of the foot and the load bearing surface contributes to foot and surface deformations and hence to perceived comfort, discomfort or pain. The plantar shapes of 16 participants' feet were captured when standing on three support surfaces that had different cushioning properties in the mid-foot region. Foot shape deformations were quantified using 3D laser scans. A questionnaire was used to evaluate the participant's perceptions of perceived shape and perceived feeling. The results showed that the structure in the mid-foot can change shape, independent of the rear-foot and forefoot regions. Participants were capable of identifying the shape changes with distinct preferences towards certain shapes. The cushioning properties of the mid-foot materials also have a direct influence on perceived feelings. This research has strong implications for the design and material selection of orthotics, insoles and footwear.

“…Some studies have found that neoprene insoles reduce transmitted forces better than viscoelastic insoles (Brodsky et al, 1988). Cook et al (1985) attributed the increase in risk of stress fractures to a loss of mechanical support or the shock-absorbing properties of the midsole of footwear.…”

“…This may suggest that differences in the training environments may influence the results. Future studies should better characterize the training environment as well as degree of shock absorbency, durability, and other important characterisfics of insoles (22). Soldiers In the U.S. Army have used running shoes for physical training since the early 19B0s.…”

ABSTRACT (Maximum 200 words)Attrition is the failure of an enlisted service member to be retained in service v/ithin the first term of enlistment. This paper emphasizes health/fitness-related aspects of attrition but also covers demographic and psychosocial factors. Overall 3-year military attrition steadily rose fi-om 26% in 1985 to 31% in 1995. Demographic and psychosocial risk factors for attrition include lower educational attaiiunent, female gender, White ethnicity, lower Armed Forces Qualification Test scores, lower moral character (less conformance to laws, rules and regulations), moral waivers, pre-service job instability, and less time in the Delayed Entry Program. The age-attrition relationship appears to be bimodal with higher attrition when youngest, decreasing in 19-23 year olds, and rising again after that. Attrition for mental health reasons is associated with pre-service physical/sexual abuse, previous mental health counseliag, previous treatment with medication, previous psychiatric hospitalization, low motivation, pessimism toward training, depression, lack of self-reliance, and referral to a mental health facility. Attrition is also higher among those waivered for hearing problems, skin disorders, back disorders, and prior knee injuries. Other health-related risk factors include pre-service injury, injuries during basic training, a history of prior cigarette smoking, low physical activity prior to service, greater body weight, higher body mass index and lower physical fitness. Strategies to reduce attrition include prescreening by biographical questionnaires, compensatory screening, individual behavioral health counseling, and realistic job previews. Senior leadership initiatives have a powerful effect on attrition. Attrition also appears to be reduced by increasing physical fitness prior to basic training, the Physical Training and Rehabilitation Program, and the Pre-Initial Entry Training Program (for National Guard). ."""""""""""""""""""." -lnitial Entry Training Program,,,,,,,,,,,,,,,,,,,,,,,,,,..... For the purposes of this paper, attrition was defined as the failure of an enlisted service member to be retained in service during their contracted first term of enlistment. This manuscript reviews a wide range of factors influencing attrition but the primary interest is in health-related factors. SUBJECT TERMS PATTERN OF ATTRITION OVER TIME AND REASONS FOR ATTRITION.Overall 3-year military attrition steadily rose from 26% in 1985 to 31% in 1995. About 1/3 of attrition occurred in the first 6 months of service, about V2 within the first year, and the remainder in the subsequent 2 year period. Separations within the first 6 months of service were associated with performance proble...

Abstract. Anatomical insoles and additions have a corrective action on the footwear user. They are intended to reduce and adequately distribute plantar pressure among support points, thus minimising the stress these points can undergo. Such customised components have traditionally been manufactured by subtractive techniques, i.e. by milling a sheet of material. Latest advances in additive manufacturing (AM) techniques and, in particular, the popularisation of 3D printing by fused deposition modelling (FDM), have opened new ways for the production of anatomical insoles. These technologies allow additional functionalities to be added, as for instance the use of materials with antimicrobial properties, or, at a structural level, zonal control in 3D design to increase cushioning capacity. The latter cannot be achieved by traditional manufacturing techniques, in that the inside of the element is not accessible. However, there are no CAD tools available for the design and production of insoles, which are specifically oriented to take advantage of the benefits that AM can bring about. This paper describes a new methodology intended for the functionalisation of anatomical insoles through a systematic approach. On the one hand, internal structures are automatically obtained by parametric design; on the other hand, the 3D geometry of the insole or addition is adequately processed so that it can be printed by FDM, thus circumventing the constraints of this production technique.
