Abstract [en]

BACKGROUND

Walking with a lower-limb prosthesis while performing a secondary task (dual-tasking) has been suggested to increase demand on attentional resources, negatively affecting balance and gait performance.[1, 2] Brain imaging research has suggested that microprocessor-controlled prosthetic knees (MPKs) reduce attentional demands during single-task walking.[3] To date the effects of MPK on brain activity during dual-task walking has not been investigated.

AIM

To evaluate effects of single- and dual-task walking on cortical brain activity in individuals using a non-MPK or MPK and controls and compare differences between the 3 groups.

METHOD

A cross-sectional study was performed involving twenty-nine individuals with a transfemoral amputation or knee disarticulation who were provided with either a non-MPK or an MPK, and 16 controls. Functional near-infrared spectroscopy was used to evaluate cortical brain activity (oxygenated haemoglobin (oxyHb) concentration level changes) while participants walked on a stable level surface and simultanously performed 2 dual-task activities; 1) walking while sorting through keys; and, 2) walking in sequence around randomly number cones. Temporospatial variables was recorded for each activity.

RESULTS

Increased brain activity (oxyHb concentration level changes) were observed when a secondary task was added in the MPK-group (p=.000) and in the control group (p=.007). No significant differences were observed between single- and dual-task walking in the non-MPK group (p>.05). Significantly increased brain activity (oxyHb concentrations level changes) was observed during single-task walking in the non-MPK group when compared to the MPK-group and controls. Significantly different results in temporospatial parameters were also observed.

DISCUSSION AND CONCLUSION

Results suggest that dual-task walking increases cognitive demand in individuals fitted with MPKs and controls. The lack of difference with the non-MPK group may suggests that their maximum capacity was already reached during single-task walking.

Abstract [en]

Police working in active duty have a high prevalence of musculoskeletal pain, with lower back pain being the most frequently reported. As a part of uniform regulations, Swedish police are mandated to wear body armour and duty belts at all times during work. This study aimed to investigate the effect of different load carriage designs on in-vehicle sitting pressure and self-rated discomfort among police. Results showed less discomfort when wearing the alternate load carriage system incorporating a load-bearing vest and thigh holster compared to the standard load carriage system consisting of a duty belt. Pressures in the lower back were reduced when wearing the load-bearing vest whereas pressures in the upper back region increased. Relocating appointments away from the waist has the potential to improve sitting positions and the ergonomic situation for police when driving fleet vehicles.

Abstract [en]

Introduction: Conflicting evidence exists regarding the effects of knee orthoses on proprioception. One belief is that pressure applied by orthoses heightens kinesthetic awareness and that this affects balance. This study aimed to investigate effects of two different orthosis designs on kinesthetic awareness and balance in healthy individuals.

Methods: Twenty individuals (13 women) participated in this case series study. Each were tested wearing 1/no orthosis, 2/soft elastic orthosis and 3/non-elastic jointed orthosis. Pressure under orthoses was recorded. Kinesthetic awareness was investigated by testing Joint Position Sense (JPS) and Threshold to Detection of Passive Motion (TDPM). Balance was tested using a Modified Sensory Organization Test (mSOT).

Results: Non-elastic jointed orthoses applied the greatest pressure to the knee. With non-elastic jointed orthoses, TDPM was significantly poorer for pooled results (p= 0.02) and when the start position of the knee was 70 degrees (mean threshold = 0.6 º, 0.6 º, 0.7º for no-orthosis, elastic and jointed-orthoses; p= 0.03). No major differences were observed in JPS or balance and correlation between proprioception and balance was poor.

Conclusions: There may be a limit to the amount of pressure that should be applied to the knee joint by an orthosis. Exceeding this limit may compromise kinesthetic awareness.

Abstract [en]

Nurses play an important role in detecting, interpreting and deciding appropriate actions to take in order to care for patients in acute situations. Nevertheless, novice nurses are reported as feeling unprepared to provide appropriate care in acute situations. In order to address this issue, it is important to describe factors in nursing education and first year of practice that enable nurses to provide appropriate care in acute situations. 17 novice nurses were interviewed in this qualitative study. A phenomenographic analysis was applied and four categories were discovered: Integrating theory into practice, access to adequate support, experience-based knowledge and personality traits. Results suggest that a variety of factors contribute to novice nurses’ ability to provide appropriate care in acute situations. Experience of acute situations and the integration of theory and practice are pivotal in acquiring skills to provide appropriate care. To accomplish this, reflection, practice and/or applied training with a patient perspective is recommended.

Abstract [en]

This instructional course is intended for graduate and post-graduate students, as well as those actively involved in research within the Prosthetics and Orthotics field.

Literature searches are a necessary component of effective research. To identify and access suitable literature, researchers need to understand which databases are most appropriate, how they differ in terms of content and search structure, and how to develop a search strategy which optimizes the proportion of relevant literature sources. Additionally, scholarly journals are increasingly requiring authors to publish utilized search strings to allow duplication of results.

The choice of terms and syntax used to construct searches within literature databases have a major influence on the outcomes of a literature search. If this process is not conducted correctly, it can result in unnecessary identification of inappropriate sources or unintended omission of appropriate literature. This instructional course will be led by academic P&Os and librarians and will equip participants with the tools to develop an advanced search strategy for a prosthetics and orthotics related topic. In addition, the concept of validated search filters, also known as search hedges, will be introduced. These can be used to efficiently and accurately filter the evergrowing volume of literature. During the course, participants will be provided with a validated search hedge which has been developed by the instructional team to be utilized when conducting a systematic search for literature within the area of limb prosthetics.

Statement of the objective / learning objectives. Upon completion, the student will:

Understand the concept of a search hedge

Make informed decisions about the selection and use of literature databases

Independently develop a search strategy for a prosthetics and orthotics related topic
