ABSTRACT

Objective: To make an initial assessment of the correlation between immersive virtual reality-based (ILBT) line bisection testing and paper-and-pencil-based line bisection (PLBT) testing in healthy subjects. Design: Diagnostic study. Setting: Research laboratory. Participants: Twenty healthy adults (51.5 [11.0] years old, 55% women; N=20). Interventions: Participants underwent an ILBT and a conventional PLBT in near space (NS) and more distant space (MDS). Correlations between the ILBT and PLBT, deviation rates in the NS and MDS, horizontal gaze distribution, and presence of virtual reality sickness (VRS) were evaluated. Main Outcome Measures: Correlation between the deviation rates of the PLBT and ILBT. Results: There was no significant correlation between the ILBT and PLBT for evaluating the deviation rate of the line bisection test (LBT). There was no significant difference in the deviation rate of the LBTs between the NS and MDS, but there was a significant difference in the horizontal line-of-sight distribution. VRS was not observed as an adverse event. Conclusions: In healthy adult subjects, our results suggested that there was no significant correlation between the deviation rates of the ILBT and PLBT. We also found that the ILBT is a useful and safe method for evaluating the horizontal line-of-sight distribution and percentage deviation of line segments from the center in the NS and MDS without inducing VRS.

ABSTRACT

The aim of this study was to assess the characteristics of visual search behavior in elderly drivers in reverse parking. Fourteen healthy elderly and fourteen expert drivers performed a perpendicular parking task. The parking process was divided into three consecutive phases (Forward, Reverse, and Straighten the wheel) and the visual search behavior was monitored using an eye tracker (Tobii Pro Glasses 2). In addition, driving-related tests and quality of life were evaluated in elderly drivers. As a result, elderly drivers had a shorter time of gaze at the vertex of the parking space both in direct vision and reflected in the driver-side mirror during the Forward and the Reverse phases. In contrast, they had increased gaze time in the passenger-side mirror in the Straighten the wheel phase. Multiple regression analysis revealed that quality of life could be predicted by the total gaze time in the Straighten the wheel phase (ß = -0.45), driving attitude (ß = 0.62), and driving performance (ß = 0.58); the adjusted R2 value was 0.87. These observations could improve our understanding of the characteristics of visual search behavior in parking performance and how this behavior is related to quality of life in elderly drivers.

ABSTRACT

Objective: To investigate the effects of walking with a cane on frontal plain bilateral hip joint loading in patients with late-stage unilateral hip osteoarthritis (OA). Design: Nonrandomized experimental design. Setting: Urban inpatient hospital. Participants: Adults (men, n=10; women, n=17) with osteoarthritis who were scheduled for total hip arthroplasty (N=27). Intervention: Gait with and without a T-cane was assessed using a 3-dimensional motion analysis system. Main Outcome Measures: Peak hip adduction moment and hip adduction moment impulse, vertical ground reaction force, and ground reaction force impulse were assessed under 4 different conditions: OA side vs non-OA side with non-cane gait, OA side vs non-OA side with cane gait, non-cane vs cane gait on OA side, and non-cane vs cane gait on non-OA side. The lateral trunk lean angle in the stance phase on both sides was compared between with and without a cane. Pain during walking with and without a cane was also determined using a visual analog scale (0=no pain; 100=most painful). Results: Walking with a cane reduced the peak hip adduction moment from an average of 0.76 to 0.57 Nm/kg (reduction approximately 25%) and the mean hip adduction moment impulse from 50.58 to 42.78 Nm/kg (reduction approximately 15%) on the affected side. Walking with a cane reduced the peak ground reaction force from an average of 10.15 to 9.20 N/kg but did not markedly affect the mean ground reaction force impulse on the affected side. The mean impulse of vertical ground force and hip adduction moment on the nonaffected side with a T-cane was larger than that without a cane (940.4 vs 899.2, 73.7 vs 68.8, respectively), albeit without statistical significance. The mean lateral trunk lean angle on the affected side was 5.85±3.95 degrees with a non-cane gait and 4.46±2.66 degrees with a T-cane gait, showing a significant difference. Furthermore, walking with a cane was associated with a significant decrease in the visual analog scale of pain from 42.1 to 26.4. Conclusion: These findings indicate that walking with a cane reduces the load and pain on the affected hip joint. The effect of the cane on the trunk lean was small, but it is worth noting that walking with a cane may increase the load on the healthy side.

ABSTRACT

Objectives: Stroke patients with hemiplegia can sometimes achieve independent life at home or in light care facilities after rehabilitation. This study examined the outcomes of rehabilitation in stroke patients with severe hemiplegia. Methods: This study included 50 patients with Brunnstrom recovery stage I-II hemiplegia at the start of rehabilitation for stroke. Good outcome after rehabilitation was defined as independent life with functional independence measure (FIM) score of 100 or greater. Predictors for post-rehabilitation functional recovery were statistically analyzed. Results: FIM scores of 100 or greater in 12 of 50 patients (24%) allowed independent life after stroke rehabilitation. According to univariate analysis, factors associated with a FIM score of 100 or greater and good prognosis after rehabilitation were younger age (<70 years), paralysis caused by intracerebral hematoma (ICH), no cortical lesions, short time from admission to comprehensive inpatient rehabilitation (CIR) for stroke (within 1 month), and good status at the start of early rehabilitation and CIR. Eleven of the 12 patients with good prognosis (FIM ≥100) had ICH and a basal ganglia lesion with no cortical damage. Analysis of the location of lesions suggested that many patients with basal ganglia ICH lesions and little cortical involvement have good prognoses. Conclusions: Stroke patients with severe hemiplegia showed a slightly different distribution of lesions between ICH and cerebral ischemia. Cortical involvement may be a prognostic factor for outcome after rehabilitation in stroke patients with severe hemiplegia. More aggressive rehabilitation interventions may be important for patients with severe hemiplegia, especially without cortical involvement.

ABSTRACT

INTRODUCTION: Patients with hip osteoarthritis (OA) show abnormal movement patterns, including the leaning of the trunk toward the affected limb (Duchenne limp). Patients with severe OA, especially those with OA due to hip dysplasia, show a lateral pelvic drop (Trendelenburg sign). AIM: The aim of this preoperative study is to investigate the relationship between superior migration of the arthritic femoral head, pain, and hip abductor muscle strength, and to clarify the relationship between the coronal plane gait patterns with pain and hip abductor muscle strength. METHODS: The subjects of this study were 18 patients with unilateral hip OA secondary to dysplasia. A radiographic analysis was performed on standardised anteroposterior pelvis films. The abductor muscle strength of the OA hip joint was measured with a handheld dynamometer. The tilt angle of the pelvis and trunk lean angle during gait were obtained using a 3-dimensional motion analysis system. Visual analogue scale (VAS) of pain was obtained after trial. RESULTS: The 2 lateral pelvic angle patterns at the mid-stance of the affected limb during gait were detected. 1 is a pattern that was pelvic rise, and the other was a contralateral pelvic drop. Subjects with pelvic drop showed more superior femoral migration than that with pelvic rise (r = 0.69 p < 0.01). VAS of pain correlate significantly with coronal trunk angle on mid-stance of affected limb during gait (r = 0.761, p < 0.01). CONCLUSION: The pelvic drop Trendelenburg sign was influenced by superior migration of the femoral head, whereas the trunk lean Duchenne limp was found to be affected by pain.

ABSTRACT

OBJECTIVE: Epidemiological longitudinal investigations of the association between not eating three meals regularly and changes in BMI and weight are scarce. The aim of this study was to investigate whether or not regularly eating three meals was associated with changes in BMI and weight in young Japanese men and women. METHODS: Study participants were 1241 men and 897 women aged 19.0±1.2 and 18.8±0.8years, respectively, who underwent health checkups at a university in Japan in 2001 as the baseline and subsequently in 2003. Weight and height were measured at baseline and 2years later. Whether an individual ate three meals regularly was determined by a self-report questionnaire in 2001. RESULTS: During the 2-year follow-up, the BMI gain was 0.347 for men and 0.067 for women. In the logistic regression analysis, for men, eating three meals irregularly was significantly associated with a 4% BMI gain (OR 1.60, CI 1.11-2.30), 6% BMI gain (OR 1.72, CI 1.12-2.63), 4kg weight gain (OR 2.01, CI 1.29-3.13), 6kg weight gain (OR 1.86, CI 1.02-3.37), and incidence of obesity (BMI ≧ 25)(OR 2.96, CI 1.22-7.17). For women, eating three meals irregularly was significantly associated with a 4% BMI loss (OR 1.99, CI 1.01-3.94), 6% BMI loss (OR 2.79, CI 1.29-6.03), 4kg weight loss (OR 3.85, CI 1.62-9.12), 6kg weight loss (OR 7.65, CI 2.06-28.46), and the incidence of underweight (OR 3.95, CI 1.32-11.89). CONCLUSIONS: The current results suggested that eating three meals irregularly was associated with subsequent BMI and weight gains for men and subsequent BMI and weight losses for women; both groups were around 20years of age. Self-reported eating behavior in this study might be used to screen and evaluate young Japanese men and women at high risk for changes in BMI and weight in a practical clinical setting.

ABSTRACT

Objective The supplementary motor area (SMA) is important for the prediction of post-operative symptoms after surgical resection of gliomas. We investigated the relationships between clinical factors and the resection range of SMA gliomas, and the post-operative neurological symptoms. Methods We retrospectively studied 18 consecutive surgeries for gliomas involving the SMA proper performed in 13 patients. Seven cases were recurrence of the tumour. Clinical factors and details of specific resection of the SMA proper (resection of posterior part, medial wall) and cingulate motor area (CMA) were examined. Results Eight cases suffered new post-operative neurological deficits. Six of these eight cases had transient deficits. Permanent deficits persisted in two cases with partial weakness or paresis, after rapid improvement of post-operative global weakness or hemiplegia, respectively. The risk of post-operative neurological deficits was not associated with the resection of the posterior part of the SMA proper or the CMA, but was associated with resection of the medial wall of the SMA proper. Surgery for recurrent tumour was associated with post-operative neurological deficits. The medial wall was frequently resected in recurrent cases. Discussion The frequency of post-operative neurological symptoms, including SMA syndrome, may be higher after resection of the medial wall of the SMA proper compared with the resection of only the lateral surface of the SMA proper.

ABSTRACT

This study retrospectively investigated 192 teenage speed and figure skaters with prior injuries documented by an athletes' questionnaire, who underwent a physical examination to assess their muscle tightness and generalized joint laxity. In all athletes, the degree of muscle tightness and joint laxity were measured by a standardized physical examination. A descriptive report of the types of injuries showed a predominance of fractures, ligament injuries, enthesitis, and lower back pain. Approximately 5% of all skaters tested positive for tightness, while 25.8% of figure skaters and 15.2% of speed skaters had generalized ligamentous laxity. Statistical testing showed an association between ankle sprains and muscle tightness, and an association between knee enthesitis and muscle tightness in skating athletes. There was also an association between lower back pain and generalized joint laxity, which held true only for the male skaters.

ABSTRACT

OBJECTIVE: The present study aimed to evaluate the quality of Internet information on the Mediterranean diet and to determine the relationship between the quality of information and the website source. DESIGN: Website sources were categorized as institutional, pharmaceutical, non-pharmaceutical commercial, charitable, support and alternative medicine. Content quality was evaluated using the DISCERN rating instrument, the Health On the Net Foundation's (HON) code principles, and Journal of the American Medical Association (JAMA) benchmarks. Readability was graded by the Flesch Reading Ease score and Flesch-Kincaid Grade Level score. SETTING: The phrase 'Mediterranean diet' was entered as a search term into the six most commonly used English-language search engines. SUBJECTS: The first thirty websites forthcoming by each engine were examined. RESULTS: Of the 180 websites identified, thirty-two met our inclusion criteria. Distribution of the website sources was: institutional, n 8 (25 %); non-pharmaceutical commercial, n 12 (38 %); and support, n 12 (38 %). As evaluated by the DISCERN, thirty-one of the thirty-two websites were rated as fair to very poor. Non-pharmaceutical commercial sites scored significantly lower than institutional and support sites (P = 0.002). The mean Flesch Reading Ease score and mean Flesch-Kincaid Grade Level were 55.9 (fairly difficult) and 7.2, respectively. The Flesch-Kincaid Grade Level score determines the difficulty of material by measuring the length of words and sentences and converting the results into a grade level ranging from 0 to 12 (US grade level). CONCLUSIONS: Due to the poor quality of website information on the Mediterranean diet, patients or consumers who are interested in the Mediterranean diet should get advice from physicians or dietitians.

ABSTRACT

OBJECTIVE: In Western countries, skipping breakfast is associated with a high prevalence of overweight and obesity. This meta-analysis aimed to determine if the same relationship exists in Asian and Pacific regions. METHODS: A systematic literature search was performed for observational studies using a cross-sectional design that examined the relationship between frequency of eating breakfast and overweight or obesity. Odds ratios (ORs) for overweight or obesity were pooled with a variance-based method. RESULTS: Nineteen studies (93,108 total participants and 19,270 overweight or obese cases) were included. The pooled OR [95% confidence intervals (CI)] of overweight or obesity for the lowest vs. highest category of breakfast frequency was 1.75 [1.57 to 1.95] (P<0.001). Between-study heterogeneity in the association's strength was highly significant (I-squared=36.4%, P<0.001), although a positive OR was shown in all but one included study. However, no study characteristics could be identified to explain the heterogeneity. CONCLUSION: This meta-analysis suggests that a positive association between skipping breakfast and overweight and obesity is globally observed regardless of cultural diversity among countries. Promoting the eating of breakfast in all populations may be beneficial.
