Skin Biopsies

Our previous studies have shown that severely atrophic Quadriceps muscles of spinal cord injury (SCI) patients suffering with complete conus and cauda equina lesions, and thus with permanent denervation-induced atrophy and degeneration of muscle fibers, were almost completely rescued to normal size after two years of home-based Functional Electrical Stimulation (h-bFES). Since we used large surface electrodes to stimulate the thigh muscles, we wanted to know if the skin was affected by long-term treatment. Here we report preliminary data of morphometry of skin biopsies harvested from legs of 3 SCI patients before and after two years of h-bFES to determine the total area of epidermis in transverse skin sections. By this approach we support our recently published results obtained randomly measuring skin thickness in the same biopsies after H-E stain. The skin biopsies data of three subjects, taken together, present indeed a statistically significant 30% increase in the area of the epidermis after two years of h-bFES. In conclusion, we confirm a long term positive modulation of electrostimulated epidermis, that correlates with the impressive improvements of the FES-induced muscle strength and bulk, and of the size of the muscle fibers after 2-years of h-bFES.

Significant Difference

Abstract Background: Few studies have examined the long-term consequences of using peroneal nerve functional electrical stimulation (FES) for people with multiple sclerosis (MS). This study examines orthotic effects on a longitudinal cohort and explores additional benefits of FES on self-reported measures such as joint pain. Methods: One hundred forty-five people with foot drop and MS were included (mean age, 52 [range, 28–74] years). Orthotic effects, unassisted walking speed, and clinically important differences (ie, ≥0.05 and ≥0.10 m/s) were derived from walking speed over 10 m. Visual analogue scales examined joint pain, walking effort, trips, confidence, and quality of life. Measures were taken on day 1, after 6 months, and at 2, 3, 4, and 5 years. Results: A significant difference was found overall for walking with FES compared with walking without FES for the 5-year period (P < .001). Despite a significant decline in overall unassisted walking speed at baseline (0.58 m/s) compared with 5 years later (0.46 m/s) (P < .001), participants achieved an orthotic effect with (0.52 m/s) versus without (0.46 m/s) FES after 5 years (P < .001). A significant decrease in joint pain was found after 6 months compared with day 1 (P = .004), which was maintained after 5 years (P < .001). Conclusions: Despite progression of MS, long-term users of FES still benefit from an orthotic effect after using FES for 5 years. The study highlights the need for further work to assess the perceived benefits of FES regarding the experience of joint pain.

As part of the work, a theoretical and experimental study (based on running dynamic tests) of the running qualities of empty hopper cars, converted from cement trucks and mineral trucks, was conducted. Computer simulation of the dynamics of empty hopper wagons converted from cement and mineral wagons depending on the condition of the track, the technical condition of the wagons and the weight of the container, the repeated presence of maximum vertical deviations and horizontal deviations of the track. A significant disadvantage of the railway transport of Ukraine is the limitation of the speed of trains with individual freight cars in an empty state, which are equipped with carts model 18-100. Among the reasons for the descent of the wheels of cars from the rails are: malfunctions of the running gear of the cars (fracture of the side frames and spring beams of the carts, malfunctions of the roller bearings of the axle box), wear of friction damper elements, unacceptable deviations and upgrades. As part of the work, a theoretical and experimental study (based on running dynamic tests) of the running qualities of empty hopper cars, converted from cement trucks and mineral trucks, was conducted. Computer modeling of the dynamics of empty hopper wagons, converted from cement and mineral wagons depending on the condition of the track, the technical condition of the wagons and the weight of the container and studies of the dependence of the wheel stability on the east.
