The interior of the ambulances are made of seamless medical grade fiber reinforced polymer (FRP) panels and joint-less medical grade polyurethane antiabrasive epoxy flooring which is antistatic, antibacterial, antifungal, antiskid, and antifire. This type of interiors is easy to clean and maintain sterile and hygienic.

Bioactive composite sandwich, consisting of Glass or Carbon Fibre Reinforced Composites (G-FRC or C-FRC) laminates and a core of Bioactive Glass (BG) particles, have also been considered for cranioplasty. G-FRC based on a methacrylic resin matrix coated with BG granules has shown the potential to promote the healing process of calvarial bone defects in rabbits (Tuusa et al. 2008). Soon after, G-FRC based on a dimethacrylic resin matrix incorporating BG granules was used, on humans, for a complex clinical case of a patient undergoing repetitive cranioplasty. The G-FRC/BG explant (after 27 months) showed osteoid formation together with small clusters of mature hard tissue being observed at the margin of the cranioplasty, suggesting that this composite represents a feasible method for calvarial reconstruction (Posti et al. 2016). A G-FRC/BG cranioplasty, based on a photopolymerized dimethacrylic resin matrix and a highly porous BG structure, has also shown antimicrobial and osteoconductivity features (Aitasalo et al. 2014). The advantage of using a photo-cured G-FRC laminate sandwich in conjunction with a BG core is that the material can be precisely layered before polymerization occurs and high load-bearing capability can be expected if the external composite laminates are properly spaced (Piitulainen et al. 2017). A three-year follow-up investigation on paediatric patients with a large cranial defect restored with a thin G-FRC laminate and a core BG scaffold concluded that this composite is a safe and a functional solution for restoring cranial defects in paediatric populations (Piitulainen et al. 2015). C-FRP medical grade implants consist of a woven carbon fabric impregnated with a biocompatible thermoset epoxy matrix. Each C-FRP lamina is laid-up on the positive templates of the cranial defect, and a 3 years follow-up on 27 patients has shown no postoperative complications (Saringer et al. 2002). Although some complications such as infection and adverse reactions may occur, excellent cranioplasty restorations through C-FRP have been observed on a wider sample (Wurm et al. 2004).

There are a few limitations to this study. First, using VA electronic medical records as our measure for medication count likely underestimates medication count by omitting medications from outside pharmacies, over-the-counter, vitamins, other supplements, and those from inpatient hospitalizations. However, we likely have an accurate measure of the number of medications from the VA that participants were consuming as we defined medication count utilizing pharmacy fill/refill data rather than prescription data alone. Second, the sample studied was predominantly male and of relatively younger age (mean age 56) compared to the geriatric population in which the frailty phenotype has been more completely characterized (typically >65 years old) (Clegg et al., 2013; Fried et al., 2001). Third, the VACS aFRP, similar to the MACS FRP does not account for weakness, which is included in the phenotype developed by Fried (Akgun et al., 2014).

The test stand is equipped with an epoxy fiber reinforced plastic (FRP) headform, which has the characteristics of light weight, high strength and good electrical insulation. The tensile strength of the headform is 150 MPa and the axial elastic modulus is 24 GPa. If the stress applied to the headform is 10 MPa, the strain on the headform is less than 0.1%, which can meet the rigidity requirements of the headform in the impact resistance test of the helmet. The headform is designed to imitate the shape of the human head, and the size meets the requirements of EU standards [27]. The headform used for the test is shown in Figure 2.
Joint motion restrictions and exaggerate muscular activities during fingertip-to-floor test in case of patients with chronic low back pains? A pilot study

The physical examination of patients with chronic Low Back Pain (cLBP) is mainly relying on physical impairment tests. Enhancement of hip and spinal flexibility is often a treatment goal of exercise therapy in patients with cLBP. Thus validated tests, like Fingertip-to-Floor (FTF) test, is needed. For that, the patient bend forward and attempt to reach for the floor with their fingertips. In relation to radiography and level of pain (evaluated with Visual Analog Scale or VAS), FTF test has been previously shown reliable in patients with LBP and validated (Perret et al. 2001). So this test is currently used before and after Functional Restoration Program (FRP). However, this test has been criticized for not measuring isolated lumbar flexion Range of Motion. Forward bending range is effectively also based on pelvic, hip, thoracic spine, dural and shoulder mobility, as illustrated with Index of Trunk Mobility (Delpierre et al. 2018). Participation in a FRP results in improved muscle strength, endurance, and physical activity. So, FTF-test give limited information of the strategies used by patients, independently of limiting parameters as joint motions restrictions and muscular activity. These two limiting parameters could be evaluated with external work (Wext) in walking condition. Wext corresponds to the mechanical work performed to move the Center of Mass (CoM), a point assimilated to the body, affected by the mass of body and subjected to external forces. In case of gait analysis, Wext is dependent of joint motion restrictions (Mahaudens and Mousny 2010) and muscular activity (Zollinger et al. 2016). But, gait is associated to higher displacements of CoM in comparison to FTF-test. It seems interesting to evaluate Wext before and after FRP. So, based on retrospective data, considering that FRP tends to limit joint motion restriction and strategies of avoidance that improves FTF test, the purpose of this pilot study was to compare VAS, FTF measure and Wext before and after FRP. We hypothesized that, associated to lower FTF outcome measure, Wext is significantly lower after FRP.
