Introduction: Work-related musculoskeletal disorders (WMSDs) represent a major problem for society, employers, and employees. These kinds of problems can cause discomfort, pain, and poor work performance. Among physiotherapists, the 1-year prevalence of WMSD ranges from 28 to 96%. Most problems occur in the lower back, with a 1-year prevalence of up to 83%. This study aimed to determine the prevalence of WMSD on a sample of physiotherapists from Slovenia and to identify associations between demographic/anthropometric variables, job satisfaction, and physical activity with WRMD aiming to contribute to the development of effective prevention and control strategies. Methods: The extended Nordic musculoskeletal questionnaire was used to obtain data from a sample of 102 physiotherapists. Data were presented with descriptive statistics and processing was performed with the Spearman’s rank correlation coefficient for non-parametric variables. The level of statistical significance was set as p ≤ 0.05. Results: The 1-year prevalence of WMSD was 92.2%. One-year prevalence of WMSD was highest for the neck (64%) and lower back (63%). Higher age and more years of practice were correlated with WMSD for shoulders and ankles/feet areas. Several patients treated by a physiotherapist were a risk factor for difficulties in the neck and multiple body areas. The level of physical activity was not correlated with WMSD in different body areas. Conclusion: The prevalence of WMSD found in our study sample was among the highest compared to other countries, despite probably having similar working conditions as elsewhere in Europe. The first WMSD of Slovenian physiotherapists mostly did not occur in the first 5 years of practice as other studies reported, which could be explained as a result of a good educational training of young physiotherapists. Possible reasons for the high prevalence of WMSD could be that our study sample represented only secondary and tertiary levels of health care; another reason could also be non-ergonomic and hard working conditions during their careers. Physiotherapists are mostly adequately physically active, however, that did not turn out to be effective WMSD prevention in our sample. The relatively high prevalence is indicating the need for better interventions and prevention of WMSD in Slovenian physiotherapists.

The aim of the study was to evaluate the predictive validity of the Modified Fall Assessment Tool (MFAT) in a nursing home setting. The study involved 83 residents from a nursing home in Slovenia with an average age of 81 years. To determine the predictive characteristics of the MFAT, a receiver operating characteristic curve analysis was applied. During the observation period of 12 weeks, 18 residents fell. The fallers had a significantly higher history of falls, a higher number of diagnoses, more medication, and a higher MFAT score than the non-fallers. Using the estimated criterion of 20 points, the sensitivity of the MFAT score was 61%, its specificity was 80%, its classification accuracy was 64%, its positive likelihood ratio was 3.1, its negative likelihood ratio was 0.5, its positive predictive value was 46%, and its negative predictive value was 88%. The results showed that the MFAT is suitable for the prediction of falls and, hence, also the prevention of falls in nursing homes, whereby the recommended criterion score is 20 points.

We aimed to elucidate potential differential effects of hypoxia on cardiorespiratory responses during submaximal cycling and simulated skiing exercise between adults and pre-pubertal children. Healthy, low-altitude residents (adults, N=13, Age=40±4yrs.; children, N=13, age=8±2yrs.) were tested in normoxia (Nor: PO=134±0.4 mmHg; 940 m) and normobaric hypoxia (Hyp: PO=105±0.6 mmHg; ~3 000 m) following an overnight hypoxic acclimation (≥12-hrs). On both days, the participants underwent a graded cycling test and a simulated skiing protocol. Minute ventilation (V), oxygen uptake (VO), heart rate (HR) and capillary-oxygen saturation (SpO) were measured throughout both tests. The cycling data were interpolated for 2 relative workload levels (1 W·kg & 2 W·kg). Higher resting HR in hypoxia, compared to normoxia was only noted in children (Nor:78±17; Hyp:89±17 beats·min; p<0.05), while SpO was significantly lower in hypoxia (Nor:97±1%; Hyp:91±2%; p<0.01) with no between-group differences. The V, VO and HR responses were higher during hypoxic compared to normoxic cycling test in both groups (p<0.05). Except for greater HR during hypoxic compared to normoxic skiing in children (Nor:155±19; Hyp:167±13 (beats·min); p<0.05), no other significant between-group differences were noted during the cycling and skiing protocols. In summary, these data suggest similar cardiorespiratory responses to submaximal hypoxic cycling and simulated skiing in adults and children.

Determination of the thermal thresholds is used clinically for evaluation of peripheral nervous system function. The aim of this study was to evaluate reliability of the method of levels performed with a new, low cost device for determining cutaneous temperature sensitivity. Nineteen male subjects were included in the study. Thermal thresholds were tested on the right side at the volar surface of mid-forearm, lateral surface of mid-upper arm and front area of mid-thigh. Thermal testing was carried out by the method of levels with an initial temperature step of 2°C. Variability of thermal thresholds was expressed by means of the ratio between the second and the first testing, coefficient of variation (CV), coefficient of repeatability (CR), intraclass correlation coefficient (ICC), mean difference between sessions (S1-S2diff), standard error of measurement (SEM) and minimally detectable change (MDC). There were no statistically significant changes between sessions for warm or cold thresholds, or between warm and cold thresholds. Within-subject CVs were acceptable. The CR estimates for warm thresholds ranged from 0.74°C to 1.06°C and from 0.67°C to 1.07°C for cold thresholds. The ICC values for intra-rater reliability ranged from 0.41 to 0.72 for warm thresholds and from 0.67 to 0.84 for cold thresholds. S1-S2diff ranged from -0.15°C to 0.07°C for warm thresholds, and from -0.08°C to 0.07°C for cold thresholds. SEM ranged from 0.26°C to 0.38°C for warm thresholds, and from 0.23°C to 0.38°C for cold thresholds. Estimated MDC values were between 0.60°C and 0.88°C for warm thresholds, and 0.53°C and 0.88°C for cold thresholds. The method of levels for determining cutaneous temperature sensitivity has acceptable reliability.

The pendulum test is a method applied to measure passive resistance of the knee. A new and simple pendulum test with instrumentation based on infrared camera was used to evaluate knee stiffness and viscosity on a female human cadaver. The stiffness and viscosity were calculated based on the kinetic data. During the measurements, the periarticular and intraarticular soft tissue of the knee was gradually removed to determine the stiffness and viscosity as a function of the tissue removal rate. The measurements showed that the removal of tissue around the joint reduces the damping of leg oscillation, and therefore decreases the stiffness and viscosity. The contribution to knee joint damping was 10% for the skin, 20% for ligaments, and 40% for muscles and tendons. Tissue removal has a very large impact on the knee stiffness and viscosity.
