Aim: To examine the effect of treadmill walking on over-weight to obese females with unspecified mild ID (intellectual disability). Method: Randomized assignment to an aerobic exercise group (G1, n = 6) and control group (G2, n = 3). The G1 performed mild to moderate intensity walking for 25-45 minutes per exercise session, 3-5 times per week up to a weekly walking of 150 minutes, for 32 consecutive weeks. The G2 maintained routine daily activities. Results: The mean age of the study subjects was 57.2 ±7.5 year, BMI was significantly decreased at the conclusion of the intervention (P = 0.005). In the G1, the subcutaneous fat area was also significantly decreased (P = 0.005) but not in G2. No change was there in the visceral fat area of both groups. The quadriceps muscle maximal isometric muscle strength of the G1 and G2 did not change. Conclusion: Long term mild to moderate intensity of aerobic physical exercise for over-weight to obese women with ID is a feasible and effective plan in reducing subcutaneous fat mass, while muscle strength remains unchanged.
目的:探讨跑步机行走对未明确轻度智力残疾的肥胖女性超重的影响。方法:随机分为有氧运动组(G1, n = 6)和对照组(G2, n = 3)。G1进行轻度至中等强度的步行，每次运动25-45分钟，每周3-5次，每周步行150分钟，连续32周。G2维持日常活动。结果:研究对象的平均年龄为57.2±7.5岁，干预结束时BMI明显下降(P = 0.005)。G1组皮下脂肪面积明显减少(P = 0.005)， G2组无明显差异。两组的内脏脂肪区域没有变化。G1和G2组的四头肌最大等长肌力没有变化。结论:长期轻度至中等强度的有氧运动对超重肥胖ID女性是一种可行有效的减少皮下脂肪量的方案，同时肌肉力量保持不变。

Aim: This study aimed at evaluating (1) if the oral training effect on stroke related dysphagia differs between two different oral appliances, a palatal plate (PP) and an oral screen (OS), and (2) if the training effect remains at a late follow-up. Methods: We included patients with stroke-related dysphagia at two different time periods: the first group of 12 patients studied in 1997- 2 002 had to train with a PP, the other one of 14 patients studied in 2003-2008 had to train with an OS. All patients were evaluated by a swallowing capacity test (SCT), and by a self-assessed visual analogue scale (VAS) of water swallowing capacity at entry of the study, after 13 weeks of training, and at a late follow-up. Results: At end of treatment the SCT had normalized in 33% of PP patients and in 71% of OS patients. There was a significant SCT improvement difference between the PP and OS groups in the period from baseline to late follow-up (p < 0.002) in favor of the OS group. VAS as tested at baseline and at end of treatment did not differ significantly between the two groups. Training with PP and with OS produced remaining improvement of SCT and of VAS as assessed at a late follow-up. Conclusion: The outcome of OS training on SCT in patients with stroke-related dysphagia seems to be superior to PP training. The improvement as assessed with VAS did not differ between the two groups. Training with PP or OS gives a longstanding improvement of SCT and VAS.

Introduction and Purpose: Optimal social participation, which is the ultimate goal targeted by rehabilitation professionals for their clients, can be defined as perfect congruence between an individual's expectations and reality. Work-family dynamic requires balance between the different spheres of a worker's life. The purpose is to explore the perception of rehabilitation professionals regarding their optimal social participation based on work-family conciliation, and the factors they identify as influencing this participation. Method: Qualitative study with a phenomenological orientation among 13 rehabilitation professionals using an interview guide consisting of open questions. The data was audio-recorded and transcribed in full (verbatim) followed by content analysis. Analysis was carried out systematically to achieve a better understanding of the facts. A proportion of the analysis (approximately 10%) was coded by another team member for validation. Results: Participants were mostly women (12/13) aged 31 to 44 years having one to three children aged from 7 months to 12 years old. Optimality of participation is perceived as the ability (or not) to carry out important activities while fulfilling one's various responsibilities. Of the five environmental factors perceived to have an influence (financial aspects, spousal support, time, flexible work schedule, and family organization), family organization appears to be a determinant of possibility and thus greatly influences individual expectations. Conclusion: Work-life balance is a complex phenomenon that should be studied holistically rather than in a segmented mode.

Aim: The first aim of this cross-sectional survey was to assess the reasons given by people with traumatic spinal cord injury (tSCI) for leaving a job that they had secured after sustaining injury. The second aim was to examine the extent to which these reasons were compatible with a previously-developed framework for understanding organizational behaviors such as leaving a position of employment. Method: Thirty tSCI patients who left a position of employment which had been secured following the injury were interviewed, and asked to report the factors associated with their withdrawal from that position of employment. Results: A large number of factors were reportedly involved in the withdrawals. These factors mirrored were those which have been identified as influencing organizational behavior among the general workforce (characteristics of the individual, of the job, and of the wider environment). The ratio of factors involved was, respectively, 8:8:1. Within the environmental factors, micro-level factors were more prevalent than macro-level factors (in the ratio of 2:1). Conclusions: As many of the individual, job, and health-related reasons are essentially immutable, the environmental factors offer more promise for the development of preventive interventions to minimize unnecessary job loss. Prominent among these environmental factors targeted in interventions would be the workplace-related factor of social support.

Objective: This study evaluated variations in functional outcome for patients participating in a multidisciplinary acute inpatient rehabilitation program specific for brain tumors at a free standing acute inpatient rehabilitation hospital. Methods: Data was collected retrospectively for 45 patients with brain tumors admitted for inpatient rehabilitation from January 1, 2008 to May 1, 2009. Primary outcome measure included Functional Independence Measure (FIM) score on admission and discharge based on discharge disposition and acute oncological treatment group. Data was collected regarding length of stay and general patient demographic information. Results: Patients receiving chemotherapy and radiation while participating in inpatient rehabilitation had the greatest statistically significant gains inFIM, FIM-D, � FIM-T, discharge FIM-T, discharge FIM-M, and FIM-E. Patients who discharged to home for continued aggressive treatment had greatest gains inFIM, FIM-D, � FIM-T, discharge FIM-T, � FIM-M, discharge FIM-M, and FIM-E. Correlation data was also established between several variables. Conclusions: Inpatient rehabilitation stay for brain tumor patients resulted in improvements of FIM score for all disposition and acute oncological treatment groups, though statistically significant differences were noted within groups. Greatest improvements were noted for patients receiving both chemotherapy and radiation therapy and patients who discharged to home for continued aggressive oncological treatment.

The work presented in this article continues our investigation of such assisted navigation solutions where the main emphasis is placed not on sensor sets or sensor fusion algorithms but on the ability of the travelers to interpret and contextualize verbal route directions en route. This work contributes to our investigation of the research hypothesis that we have formulated and partially validated in our previous studies: if a route is verbally described in sufficient and appropriate amount of detail, independent VI travelers can use their O&M and problem solving skills to successfully follow the route without any wearable sensors or sensors embedded in the environment. In this investigation, we temporarily put aside the issue of how VI and blind travelers successfully interpret route directions en route and tackle the question of how those route directions can be created, generated, and maintained by online communities. In particular, we focus on the automation of path inference and present an algorithm that may be used as part of the background computation of VGI sites to find new paths in the previous route directions written by online community members, generate new route descriptions from them, and post them for subsequent community editing.

Purpose: A bladder control system for spinal cord injured (SCI) patients is needed that can be implanted with minimally invasive methods. New Permaloc bipolar electrodes consisting of 6 mm helical, wire, stimulating surfaces separated by 3 mm and a polypropylene securing barb (Synapse Biomedical Inc) were developed for this application. They are implanted on the bladder wall with a 16 gauge needle, a minimally invasive method. Methods: Seven swines were anesthetized, the lower urinary tract exposed and instrumented with pressure transducers. Four Permaloc TM electrodes were implanted following identification of effective bladder wall stimulation sites next to the ureters and dorsal neurovascular bundle. Bladder stimulation to induce high pressures was conducted at 40 Hz, 400 � s pulses, 5 s stimulation periods and a high stimulating current of 40 mA. Results: At the high stimulating current peak bladder pressures were low, ranging from 12±2 to15±3 cm H20, insufficient to induce urination. Urethral sphincter contractions occurred during high bladder pressure. A spinal reflex role for high sphincter pressures during stimulation was shown by similar high pressures recorded during a bladder squeeze test without stimulation. Conclusions: Stimulation with Permaloc TM bipolar electrodes at high currents produced insufficient bladder pressures for urination. Further modifications of the electrode such as greater separation of the bipolar stimulating surfaces or changes in the testing methods such as alternative animal models are needed to induce high bladder pressures without side effects.

Evaluation of patellar tracking has been suggested as an increasingly relevant diagnostic tool in patients with patellofemoral disorders. This study aimed to assess the accuracy of measuring in vivo patellar tracking with the use of a custom-made clamp. Nine healthy female college students participated. Sagittal-view fluoroscopy was used to track the movement of the clamp and the underlying patella of each subject's dominant leg during a lunge. The movement patterns (tilt angle and displacement) as well as the absolute angle/distance between the patella and clamp were investigated at 7 knee flexion angles (0°, 15°, 30°, 45°, 60°, 75°, and 90°). The patella and clamp showed similar movement patterns (tilt angle: r= 0.94, P= 0.002; displacement: r= 0.90, P= 0.007). The root mean squared error of less than 3.5° and 0.6 cm were identified below knee flexion 60°. The absolute angle significantly changed at knee flexion 90° compared to 0° (P= 0.016). The absolute distance between the upper edge of the patella and clamp significantly changed at knee flexion 60° to 90° as compared to 0° (all P< 0.05). The angle/distance change may represent an influence of a skin motion artifact manifesting beyond knee flexion 60°. With careful consideration, the custom-made clamp may offer reasonably accurate representations of patellar motion that can be used to further study patella pathologies and develop computational models.

The purpose of this study was to compare four common rehabilitation exercises used in physical therapy clinics for activating the vastus medialis oblique (VMO) and vastus lateralis (VL). Thirty-four subjects, aged 22-28 years, without patellofemoral pain syndrome (PFPS) (18 females and 16 males) were recruited. Subjects performed four exercises—straight leg raise with neutral and externally rotated hip positions (SLRN, SLRER), and short arc quad with neutral and externally rotated hip positions (SAQN, SAQER). The integrated electromyographic (iEMG) activity of the VMO and VL and were recorded, with means of the VMO, VL and VMO/VL compared across exercises. No significant difference was found for the VMO/VL ratio across the four exercises (p=0.147). However, for the VMO and VL individually, a significant difference was found (p=0.0001), SAQER was significantly greater than SLRN and SLRER; SAQN was significantly greater than SLRN and SLRER. These findings suggest that exercises including short arc quad knee extensions are more effective for both the VMO and VL activation than those incorporating straight leg raises, and potentially more beneficial in the rehabilitation of patients with PFPS.

Aim: This exploratory study assessed (1) the associations between three major types of social support (perceived, actual and structural) and post-injury daily functioning and (2) the ability of subjective-objective social support dyads to predict rehabilitation outcome among traumatic spinal cord injury (SCI) patients one-year post- discharge. Method: Using a prospective study design, 20 SCI patients of workforce age discharged from the Royal Talbot Rehabilitation Hospital, Melbourne, Australia during 2007 were assessed on a range of demographic, injury and social support variables. Post-injury daily functioning was assessed 12-months post-discharge. Results: Bivariate analyses revealed that the three major types of social support were associated with better post-injury daily functioning. Multivariate analyses revealed that the dyad of (subjective) perceived social support and (objective) community integration was the best predictor of successful rehabilitation outcome. For all three social support dyads, the subjective component contributed greater unique variance to the overall predictive ability of the model than did the accompanying objective component. Conclusions: Use of psychometrically sound scales that incorporate objective and subjective measures of social support may provide a more effective means of evaluating the contribution of social support to rehabilitation outcome, plus indicate whether desired social support levels satisfactorily match those received.
