Impairment of motor function following peripheral nerve injury is a serious clinical problem. Generally nerve injury leads to erroneous control of muscle activity that results in gait and voluntary movement abnormalities followed by muscle atrophy. This article presents a review of studies on the effects of peripheral nerve injury on the motor system performed on animal models. We focused our attention on the results that are fundamental for better understanding of the degenerative and regenerative processes induced by nerve injury as well as of the mechanisms of structural changes in neuronal networks controlling movement. Quoted results are also important for clinical applications because they allow to develop new diagnostic and therapeutic techniques that can be used after nerve injury inducing motor deficits. However, till now no efficient therapy inducing satisfactory recovery was found. There is still a need to continue an advanced basic research directed to develop effective therapies. Thus the aim of this review is to compare the results of recent studies performed on various animal models in order to propose new methods for identification of mechanisms responsible for muscle deficits and propose targets for new pharmacological therapies.

The Spine Buddy® supportive pad was developed to be inserted underneath military backpacks to help disperse the heavy load of the backpack. The purpose of this study was to determine the impact the additional supportive pad had on static balance and a running gait while wearing a military backpack. Forty healthy subjects (age= 27.5 + 5.6 yrs, body height= 1.78 + 0.06 m, body mass= 86.5 + 14.0 kg: mean + SD) participated in a static single-leg balance test on a force plate with each lower limb while wearing a 15.9 kg military backpack for 30 s. Following this, participants were randomized to one of two interventions: 1) Intervention, which wore the Spine Buddy® supportive pad underneath their backpack or 2) Control, with no additional supportive pad. Post-intervention measurements of static single-leg balance were then recorded. Afterwards, a similar pre vs post testing schedule and randomization scheme was used to test the impact of the supportive pad on a 5 mph jogging gait using Vicon® cameras. Within-group data were analyzed with a 2-way repeated measures ANOVA. Statistically significant differences were not seen between the control and experimental group for balance and gait variables. Preliminarily, this suggests that the Spine Buddy® supportive pad causes no deleterious effect on static balance and a jogging gait in 18-45 year-old asymptomatic individuals.

Celem pracy było określenie zależności pomiędzy szkolną a całodniową aktywnością fizyczną 16-letnich dziewcząt i chłopców na podstawie tygodniowego monitoringu z wykorzystaniem krokomierzy. W badaniu uwzględniono również poziom całodziennej i szkolnej aktywności fizycznej uczniów mniej i bardziej aktywnych w czasie przed zajęciami w szkole. Przebadano 169 osób, w tym 93 dziewczęta i 76 chłopców ze szkół ponadgimnazjalnych regionu śląskiego. Badani nosili krokomierz przez 5 dni szkolnych zapisując liczbę wykonanych kroków w poszczególnych segmentach dnia (czas przed zajęciami w szkole, zajęcia w szkole i czas po zakończeniu zajęć w szkole) w specjalnie przygotowanych tabelach. Wyniki badań wskazały, że dziewczęta są bardziej aktywne pod względem liczby wykonywanych kroków w dni szkolne od chłopców. Dziewczęta i chłopcy spełniają rekomendację szkolnej liczby kroków w wymiarze 3 000. Zaobserwowano natomiast różnicę w aktywności fizycznej uwzględniając podział badanych na mniej i bardziej aktywnych w czasie przed zajęciami szkolnymi. Uczniowie mniej aktywni pod względem liczby kroków wykonanych przed rozpoczęciem zajęć w szkole nie spełniają zalecanej szkolnej rekomendacji aktywności fizycznej. Poszukiwanie rezerw aktywności fizycznej w całym dniu jest konieczne. Oprócz lekcji wychowania fizycznego szkoła powinna popularyzować aktywność podczas przerw międzylekcyjnych, ćwiczeń śródlekcyjnych, czy też zachęcać do aktywnej lokomocji przed i po zajęciach w szkole. Zachęcanie do zwiększonej liczby spacerów, aktywnego transportu do/ze szkoły, jazdy na rowerze, łyżworolkach wśród dzieci i młodzież jest ważnym elementem w przygotowaniu do całożyciowej aktywności i zdrowego stylu życia.

The aim of the work was to determine the relationship between school and all-day physical activity of 16-year-old girls and boys based on weekly monitoring using pedometers. The research also took into account the level of all-day physical activity of less and more active pupils before school classes. 169 people were examined, including 93 girls and 76 boys from secondary schools of the Silesian region. The subjects wore a pedometer for 5 school days, recording the number of steps performed in individual segments of the day (time before classes at school, during classes at school and time after completing classes at school) in specially prepared tables. The research results indicated that girls are more active in terms of the number of steps taken on school days from boys. Girls and boys meet the recommendation of the school number of steps in the dimension of 3 000. However, the difference in physical activity was observed, considering the division of respondents into less and more active in time before school classes. Students who are less active in terms of the number of steps taken before the start of classes at school do not meet the recommended school recommendation of physical activity. It is necessary to look for reserves of physical activity throughout the day. In addition to physical education lessons, the school should promote activity during breaks, mid-term exercises or encourage active locomotion before and after school classes. Encouraging an increased number of walks, active transport to/from school, cycling, roller skating among children and adolescents is an important element in the preparation for lifelong activity and a healthy lifestyle.
