Hip muscle response to a fatiguing run in females with iliotibial band syndrome

Impaired hip muscle function has often been cited as a contributing factor to the development of iliotibial band syndrome (ITBS), yet our full understanding of this relationship is not well established. The objective of this study was to examine the effect of fatigue on hip abductor muscle function in females with ITBS. Female runners, 20 healthy and 12 with a current diagnosis of ITBS, performed a treadmill run to fatigue. Prior-to and following the run to fatigue, gluteus medius strength and median frequency values (an indicator of fatigue resistance) were measured. Additionally, onset activation timing of the gluteus medius and tensor fascia latae was measured during overground running. Both healthy and injured runners demonstrated decreased gluteus medius strength following the run to fatigue (p = 0.01), but there was no interaction between groups (p = 0.78). EMG onset activation timing did not differ between groups for the gluteus medius (P = 0.19) and tensor fascia latae muscles (P = 0.52). Injured runners demonstrated decreased gluteus medius initial median frequency values suggestive of fatigue (P = 0.01). These findings suggest that the gluteus medius muscle of female runners with ITBS does not demonstrate gross strength impairments but does demonstrate less resistance to fatigue. Clinicians should consider implementation of a gluteus medius endurance training regimen into a runner’s rehabilitation program.     

Psychological aspects of scuba diving injuries: Suggestions for short-term treatment from a psychodynamic perspective

Dive medicine is described as an area of practice in which psychologists may choose to expand their clinical service and research activities. The author argues that most research studying risk behavior and sports take into account biological, behavioral or cognitive approaches, while ignoring unconscious conflict in risk-taking and injury management. The present paper uses a psychodynamically-oriented, interview-based approach to studying psychological reactions to decompression sickness in three experienced scuba divers. Brief interventions and their outcomes are described.     

脑外伤患者内隐记忆康复护理可行性研究

探讨脑外伤患者在高强度练习和准确反馈条件下,内隐学习知识效应和底层规则迁移易化能力。结果发现：①脑外伤患者在汉字整体偏好深加工的非显著特征学习与对照组一样有效;在笔划浅加工的显著特征学习,明显低于对照组;在自由回忆和再认的重复测验中,患者组与对照组存在显著性差异。②脑外伤患者学习记忆具有整体性、直观性、模糊抽象性、无意识性等特点。③脑外伤患者存在着内隐学习知识效应和内隐知识学习效应,且随着训练强化和训练方法的改进,有增强和外显记忆转化的趋势。     

EFFECT OF SUPPORTED EMPLOYMENT ON THE VOCATIONAL OUTCOMES OF PERSONS WITH TRAUMATIC BRAIN INJURY

This paper reports the job placement of 5 males with severe traumatic brain injury. An individual placement model of supported employment was used. All individuals were placed in competitive employment and received staggered intervention over time by trained employment specialists. A multiple baseline design across persons was used to evaluate results. All individuals had been unable to work consistently or at all in competitive work environments. The range of wages was $4.25 to $5.00 per hour with an average of 339 hours of employment specialist intervention time required per case. The major problems experienced by employment specialists were insubordinate and disruptive behaviors as well as other inappropriate social behaviors displayed at the job site.     

Adapting Cognitive Processing Therapy to Treat Co-Occurring Posttraumatic Stress Disorder and Mild Traumatic Brain Injury: A Case Study

This case study aims to provide evidence for the effectiveness of adapting a particular manualized cognitive behavioral therapy intervention to treat co-occurring posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI). This study presents the treatment of a woman who experienced co-occurring mTBI and PTSD following a motor vehicle accident, a dual diagnosis that was established through a flexible assessment approach involving interviews as well as standardized psychological, neuropsychological, and neurobehavioral testing. Treatment planning led to a-priori adaptation of Cognitive Processing Therapy (CPT) to treat both her PTSD symptoms and the sequelae associated with her mTBI. The therapist maintained fidelity to the manualized structure and content of CPT protocol, adapting portions of the treatment to add specific emphasis on issues of identity confusion and role loss in service of addressing these common functional impairments that can accompany mTBI. Discussion focuses on application of CPT for future treatment of comorbid PTSD and TBI amidst complicating factors, including role losses and medical and safety issues. This case study is especially relevant due to the prevalence of co-occurring PTSD and TBI across a variety of populations.     

A correlation between sickness or injury within two weeks,chronic diseases and fatigue among adults aged 18–45 years

To investigate the prevalence of fatigue, the relationship between sickness or injury within two weeks, chronic diseases and fatigue among adults aged 18–45 years. Thousand five hundred and seventy nine individuals were included in this cross-sectional study. The Chalder Fatigue Scale (CFS) was used to assess fatigue defined as CFS score ≥4. The prevalence of fatigue was 25% in this study. Our results showed that only sickness or injury within two weeks (odds ratio [OR]: 2.440) and chronic diseases (OR: 1.727) were significantly related to fatigue. Moreover, their ORs for fatigue remained the same in all models (binary logistic regression models with adjusting for demographic and health-related characteristics one by one). In conclusion, fatigue was prevalent among adults aged 18–45 years. Sickness or injury within two weeks and chronic diseases were the risk factors for fatigue independent of demographic and health-related characteristics.     

Secondary task engagement and disengagement in the context of highly automated driving

During highly automated driving (level 3 automation according to SAE International, 2014) people are likely to increase the frequency of secondary task interactions. However, the driver must still be able to take over control within a reasonable amount of time. Previous studies mainly investigated take-over behavior by forcing participants to engage in secondary tasks prior to take over, and barely addressed how drivers voluntarily schedule secondary task processing according to the availability and predictability of automated driving modes. In the current simulator study 20 participants completed a test drive with alternating sections of manual and highly automated driving. One group had a preview on the availability of the automated driving system in upcoming sections of the track (predictive HMI), while the other drivers served as a control group. A texting task was offered during both driving modes and also prior to take-over situations. Participants were free to accept or reject a given task, taking the situational demands into account. Drivers accepted more tasks during highly automated driving. Furthermore, tasks were rejected more often prior to take-over situations in the predictive HMI group. This was accompanied by safer take-over performance. However, once engaged in a task, drivers tended to continue texting even in take-over situations. The results indicate the need to discriminate different aspects of task handling regarding self-regulation: task engagement and disengagement.     

A review of social disinhibition after traumatic brain injury

Acquired social disinhibition refers to a debilitating behavioural syndrome commonly reported after a severe traumatic brain injury (TBI) and is characterized by inappropriate social behaviour, often described as immaturity and insensitivity towards others. These behaviours can have enduring effects on the social capability of the individual and their relationships with others. However, research into socially disinhibited behaviour after TBI has been thwarted by a lack of consensus in the literature on definition and measurement. This review provides an overview of our current understanding of the definition, measurement, prevalence, associated outcomes, neuropathology, and underlying mechanisms of social disinhibition after TBI. In addition, suggestions are made for future research to further our understanding of this syndrome with the eventual aim of rehabilitating problematic behaviours. It is concluded that an improved understanding of what causes disinhibited behaviour after TBI will be necessary for the development of effective treatment strategies aimed at the rehabilitation of underlying impairments.
