Since the thorax and pelvis are primary determinants of normal and pathological walking, it is important to know how gait performance is influenced when the trunk is constraint. The objective of this study is to investigate the effect of a thoracolumbosacral orthosis (TLSO) on gait performance in healthy adults during overground walking. Methods: Fourteen healthy volunteers walked with and without TLSO. Outcome measures consisted of spatiotemporal parameters and clinically important joint angular time profiles of the lower limbs. Joint angular time profiles were assessed in the sagittal, frontal and transversal plane. A paired t-test was used for discrete parameters and spm1d for assessing the joint angular time profiles. Results: Walking with a constraint resulted in decreased stride time and step time, increased step width and cadence. In the sagittal plane, no significant differences were observed regarding joint kinematics in the hip, knee and ankle. In the frontal plane, decreased adduction during stance and abduction during swing was observed in the hip. In the transversal plane, increased external rotation of the hip and increased internal rotation of the ankle was seen when wearing a contstraint. Conclusions: Wearing a TLSO can already bring forth significant changes in gait performance, suggesting an important relationship between trunk movements and mobility.

The study aimed to examine the influence of body composition and menopause characteristics on certain temporal parameters of the behavior of vertical and anteroposterior components of ground reactive forces, as well as the vertical and anteroposterior rates on the walking of postmenopausal women. The sample consisted of 67 postmenopausal women, average age 59 years. Body composition was assessed by octapolar bioimpedance and ground reactive force by the Kistler force platform. Vertical loading rate correlated positively with age (r = 0.02) and negatively with weight (r = –0.33). The relationship between the rates of vertical loading and unloading associated positively with menopause time (r = 0.27) but negatively with weight (r = –0.27). Vertical unloading rate showed a negative association with abdominal visceral adiposity (r = –0.27). The relationship between the times of the intermediate and final phases of the support correlated significantly with abdominal visceral adiposity (r = 0.25) and fat mass (r = 0.24). The study suggests that fat mass and abdominal visceral adiposity affect the support time, and increased abdominal visceral adiposity implies a slower pre-suspension phase during the walking of postmenopausal women. Hormone replacement therapy was shown to be an enhancer of steeper vertical loading and anteroposterior unloading and longer time in the double support phase, indicating a greater stability of postmenopausal women when walking.

Producenci odbiorników GPS wychodząc naprzeciw oczekiwaniom sportowców oraz uczestników różnych rekreacyjnych form ruchu, proponują wiele łatwych w użyciu przenośnych urządzeń umożliwiających odbiór sygnałów nawigacji satelitarnej GPS. W artykule dokonano porównania charakterystyk technicznych oraz przedstawiono wyniki badań ośmiu urządzeń GPS wykorzystywanych w sporcie, w podziale na trzy grupy: odbiorniki dedykowane do dyscyplin sportowych, ogólnodostępne rejestratory oraz telefony komórkowe wykorzystujące pomiary GNSS. Ocenę dokładności wyznaczeń przeprowadzono w oparciu o badania dokładności powtarzalnej i przewidywanej na punkcie geodezyjnym POLREF 5501 w Rybinie. Jednocześnie zaprezentowano uwagi autorów dotyczące przydatności urządzeń GPS w monitorowaniu lokomocji człowieka. Wyniki pomiarów stanowią pierwszy etap prac badawczych, których celem jest ocena przydatności zróżnicowanych technik pomiarowych GNSS w badaniu lokomocji w sporcie.

Producers of GPS receivers nowadays offer many easy to use, mobile units for amateur and professional sportsmen. The article compares technical aspects of different GPS devices and presents the results of tests of eight GPS sport-receivers. The selected GNSS units were divided into groups: dedicated to sports, dataloggers and implemented in mobile phones. The tests were carried out using repeatable and predictable accuracy measurements done on the geodetic network point located in Rybina (POLREF 5501). The geodetic coordinates were transformed in Gauss-Kruger projection to conformal x, y coordinates and statistical distributions were calculated. The article also presents a discussion on other, important in the functional point of view, GPS receiver characteristics, used by sportsmen.

Nowoczesne metody rehabilitacji nie zastąpią adaptacji pacjenta do wózka inwalidzkiego oraz nauki poruszania się na nim. Wózek inwalidzki stanowi podstawę lokomocji dla osób ze znacznym uszkodzeniem rdzenia oraz dla pacjentów paraplegików z nie-wielkimi niedowładami, ale obciążonych współistniejącymi chorobami układu krążenia i oddechowego. Istotny element stanowi wyposażenie pacjenta w odpowiedni wózek i poduszkę przeciwodleżynową. Wszystkie działania mają na celu przeciwstawienie się statycznemu trybowi życia osoby po urazie rdzenia kręgowego, zwiększenie niezależności funkcjonalnej, poprawienie jakości życia i profilaktykę powikłań medycznych.

The modern methods can not replace the adaptation of a patient toa wheel chair and education on its operation. The wheel chair is still the basis of locomotion for people with considerable spinal cord damage, as well as for patients-paraplegics with small paresis, but who are loaded with co-existing illnesses of circulatory and respiratory systems. The essential element in rehabilitation is patient's equipment and ortopedic supports, such as: a wheel chair and anti-decubitus ulcers pillows. The aim of all of these activities is to prevent the static lifestyle of paraplegics, to improve the quality of life and to prevent medical complications.

Hiking trails have been growing in popularity in the health and well-being promotion. Consequently, the foot became an object of study in order to understand the discomfort and pain in the lower limb. The aims of the work were: 1) to detect tendencies for behaviour of maximum values of plantar pressure (MaxP) during the walk on different slopes, 2) to contribute to the methodology of the difficulty level of hiking trails. Equations show strong tendencies (R2 > 0.8) of behaviour of MaxP in the lateral zones of the heel, 4th and 5th metatarsus as well as in the plantar zone of the hallux. The analysis of the difficulty level of the hiking trails branches deserves a separate presentation, including the technical difficulty analysis (with a compulsory emphasis on the biomechanics) and information on the caloric consumption and on the slopes of each branch.

The three-dimensional analysis of the locomotion was carried out in a patient after resection of the medial meniscus in the left knee joint, using Vicon system. Examinations were performed two times. On the basis of the first examination an intensive three-month physiotherapy was planned and carried out. Angular changes of lower limb joints and changes of length of the selected muscles were taken into consideration.
