Objective

To compare the risk of falls and fall predictors in patients with Parkinson disease (PD), multiple sclerosis (MS), and stroke using the same study design.

Design

Multicenter prospective cohort study.

Setting

Institutions for physical therapy and rehabilitation.

Participants

Patients (N=299) with PD (n=94), MS (n=111), and stroke (n=94) seen for rehabilitation.

Interventions

Not applicable.

Main Outcome Measures

Functional scales were applied to investigate balance, disability, daily performance, self-confidence with balance, and social integration. Patients were followed for 6 months. Telephone interviews were organized at 2, 4, and 6 months to record falls and fall-related injuries. Incidence ratios, Kaplan-Meier survival curves, and Cox proportional hazards models were used.

Results

Of the 299 patients enrolled, 259 had complete follow-up. One hundred and twenty-two patients (47.1%) fell at least once; 82 (31.7%) were recurrent fallers and 44 (17.0%) suffered injuries; and 16%, 32%, and 40% fell at 2, 4, and 6 months. Risk of falls was associated with disease type (PD, MS, and stroke in decreasing order) and confidence with balance (Activities-specific Balance Confidence [ABC] scale). Recurrent fallers were 7%, 15%, and 24% at 2, 4, and 6 months. The risk of recurrent falls was associated with disease type, high educational level, and ABC score. Injured fallers were 3%, 8%, and 12% at 2, 4, and 6 months. The only predictor of falls with injuries was disease type (PD).

Conclusions

PD, MS, and stroke carry a high risk of falls. Other predictors include perceived balance confidence and high educational level.  相似文献

Objectives

To compare physiological impairments between persons with multiple sclerosis (MS) with a history of falls and persons with MS without a history of falls, and to investigate the association between physiological impairments and dynamic balance.

Design

Cross-sectional study.

Setting

University motion analysis laboratory.

Participants

Persons with MS (N=55; 27 recurrent fallers and 28 nonfallers). Participants were classified as fallers if they self-reported ≥2 falls in the previous 6 months.

Interventions

None.

Main Outcome Measures

Physiological impairment was assessed with sensorimotor delays, spasticity, plantar cutaneous sensation, and the sensory, cerebellar, and pyramidal subscales of the Expanded Disability Status Scale (EDSS). Dynamic balance was assessed using the average and variability of margin of stability and variability of trunk accelerations.

Results

Compared with nonfallers, fallers had lower plantar sensation, longer sensorimotor delays, more spasticity, and more impairment in the pyramidal and cerebellar subscales of the EDSS. Additionally, these impairments were all moderately to strongly correlated with worse dynamic balance.

Conclusions

This study highlights the multifactorial nature of instability in persons with MS. A better understanding of the physiological mechanisms of dynamic instability in persons with MS can be used to improve methods of monitoring disease progression, identifying which impairments to target through interventions, and appropriately evaluating intervention efficacy.  相似文献

Objective

To identify predictors for employment status after 10 years in a cohort of people with multiple sclerosis (MS), with the aim to increase knowledge concerning factors present at an early stage that are important for working life and work-life balance.

Design

A 10-year longitudinal observational cohort study.

Setting

University hospital.

Participants

A consecutive sample of people with MS (N=154) of working age were included at baseline, of which a total of 116 people participated in the 10-year follow-up; 27 people declined participation and 11 were deceased.

Interventions

Not applicable.

Main Outcome Measures

Baseline data on personal factors and functioning were used as independent variables. Employment status 10 years after baseline, categorized as full-time work, part-time work, and no work, was used as the dependent variable. A generalized ordinal logistic regression was used to analyze the predictive value of the independent variables.

Results

Predictors for full- or part-time work after 10 years were young age (P=.002), low perceived physical impact of MS (P=.02), fatigue (P=.03), full-time work (P=.001), and high frequency of social/lifestyle activities (P=.001) at baseline. Low perceived physical impact of MS (P=.02) at baseline also predicted full-time work after 10 years.

Conclusions

This study underlines the complexity of working life for people with MS, and indicates that it may be valuable to give more attention to the balance between working and private life, both in clinical practice and future research, to achieve a sustainable working life over time.  相似文献

Objective

This study examined aerobic capacity, upper leg muscular strength, and static postural control as correlates of the energetic cost of walking (Cw) in moderate multiple sclerosis (MS) mobility disability.

Design

Cross-sectional study.

Setting

University-based laboratory.

Participants

Persons (N=44) with MS (aged 48.43±8.64 years) who have reached a benchmark of moderate mobility disability (ie, Expanded Disability Status Scale scores between 4.0 and 6.0) participated in the study.

Main Outcome Measures

Cw was based on (1) net oxygen consumption collected using a portable metabolic unit and (2) walking speed during the 6-minute walk test. Participants underwent standard assessments of peak aerobic capacity, upper leg muscular strength, and static postural control.

Results

The data were analyzed using bivariate correlation and linear regression analyses. Cw was inversely correlated with peak oxygen consumption (r=–.308, P<.05), peak power output (r=–.548, P<.00), and peak torque at 75° knee flexion (r=–.340, P<.05), whereas Cw was positively correlated center of pressure area sway (r=.319, P<.05), and mediolateral sway velocity (r=.411, P<.05). 40.3% of variance in Cw was explained by peak power output (β=–.526, P<.01) and mediolateral sway velocity (β=.339, P<.05).

Conclusion

Our findings demonstrate that aerobic power and postural sway may be important correlates of Cw in moderate MS mobility disability. Peak power output reflects a person’s physiological functional reserve that is directly relevant for understanding the penalty of walking impairment on the energetic demands of walking. The association between mediolateral postural sway and Cw suggests that mechanical inefficiency controlling the trajectory of the body’s center of pressure during ambulation may contribute to the elevated Cw.  相似文献

Objective

To assess the effects of an 8-week aquatic exercise training program on functional capacity, balance, and perceptions of fatigue in women with multiple sclerosis (MS).

Design

Randomized controlled design.

Setting

Referral center of an MS society.

Participants

Women (N=32; mean age ± SD, 36.4±8.2y) with diagnosed relapsing-remitting MS. After undergoing baseline testing by a neurologist, participants were allocated to either an intervention (aquatic training program, n=17) or a control group (n=15).

Interventions

The intervention consisted of an 8-week aquatic training program (3 supervised training sessions per week; session duration, 45–60min; 50%–75% estimated maximum heart rate).

Main Outcome Measures

Six-minute walk test (6-MWT), balance (Berg Balance Scale [BBS]), and perceptions of fatigue (Modified Fatigue Impact Scale; [MFIS]) at baseline and after the 8-week intervention. Differences over time between the experimental and control groups were assessed by a 2×2 (group by time) repeated-measures analysis of variance.

Results

Thirty-two women completed the 8-week aquatic training intervention (experimental group, n=17; control group, n=15). All outcome measures improved in the experimental group: 6-MWT performance (pretest mean ± SD, 451±58m; posttest mean ± SD, 503±57m; P<.001); BBS (pretest mean ± SD, 53.59±1.70; posttest mean ± SD, 55.18±1.18; P<.001), and MFIS (pretest mean ± SD, 43.1±14.6; posttest mean ± SD, 32.8±5.9; P<.01). A significant group-by-time interaction was evident between the experimental and control groups for 6-MWT (P<.001, partial eta2p2]=.551), BBS (P<.001, ηp2=.423), and MFIS (P<.001, ηp2=.679).

Conclusions

Aquatic exercise training improved functional capacity, balance, and perceptions of fatigue in women with MS.  相似文献

Objective

To examine moderators of treatment effects in a randomized controlled trial comparing a telehealth self-management intervention with a telehealth multiple sclerosis (MS) education intervention for fatigue, pain, and mood in adults with MS.

Design

Secondary analysis of a single-blind randomized controlled trial.

Setting

Community.

Participants

Adults with MS and chronic fatigue, chronic pain, and/or moderate depressive symptoms (N=163) recruited from across the United States.

Interventions

Two 8-week, telephone-delivered symptom interventions delivered 1:1: a self-management intervention (n=75) and an MS education intervention (n=88).

Main Outcome Measures

Outcome measures were fatigue impact pain interference, and depressive symptom severity assessed at baseline and posttreatment. Potential moderators of treatment effects assessed at baseline were demographics (age, sex, and education), clinical characteristics (disease duration and disability severity), symptoms (perceived cognitive impairment and pain intensity), baseline levels of the treatment outcomes (pain interference, fatigue impact and depressive symptom severity), and cognitive behavioral factors (pain catastrophizing, fatigue catastrophizing, self-efficacy, and patient activation).

Results

Moderation analyses found significant moderation for fatigue impact but not for pain intensity or depressive symptom severity. Baseline patient activation interacted with treatment group to predict fatigue impact at posttreatment (P=.049). Among participants with high baseline patient activation, the self-management group reported significantly less fatigue at posttreatment than the education group. No other variables moderated the study outcomes.

Conclusions

At the group level, participants responded to both interventions, regardless of disease characteristics, demographics, symptom levels, and cognitive behavioral factors. Self-management and education are both potentially beneficial symptom treatments that may be recommended to individuals with MS and chronic pain, fatigue, and/or depressive symptoms.  相似文献

Objectives

To examine the effect of experimental knee pain on perceived knee pain and gait patterns and to examine the efficacy of transcutaneous electrical nerve stimulation (TENS) on perceived knee pain and pain-induced knee gait mechanics.

Design

Crossover trial.

Setting

Biomechanics laboratory.

Participants

Recreationally active, individuals without musculoskeletal pain aged 18 to 35 years (N=30).

Interventions

Thirty able-bodied individuals were assigned to either a TENS (n=15) or a placebo (n=15) group. All participants completed 3 experimental sessions in a counterbalanced order separated by 2 days: (1) hypertonic saline infusion (5% NaCl); (2) isotonic saline infusion (0.9% NaCl); and (3) control. Each group received sensory electrical stimulation or placebo treatment for 20 minutes, respectively.

Main Outcome Measures

Perceived pain was collected every 2 minutes using a 10-cm visual analog scale (VAS) for 50 minutes and analyzed using a mixed model analysis of covariance with repeated measures. Gait analyses were performed at baseline, infusion, and treatment. Sagittal and frontal knee angles and internal net joint torque across the entire stance were analyzed using a functional data analysis approach.

Results

Hypertonic saline infusion increased perceived pain (4/10cm on a VAS; P<.05) and altered right knee angle (more flexion and less abduction; P<.05) and internal net joint torque (less extension and greater abduction; P<.05) across various stance phases. TENS treatment reduced perceived pain and improved right sagittal gait abnormalities as compared with placebo treatment (P<.05).

Conclusions

This pain model increases perceived pain and induces compensatory gait patterns in a way that indicates potential quadriceps weakness. However, TENS treatment effectively reduces perceived pain and restores pain-induced gait abnormalities in sagittal knee mechanics.  相似文献

Objective

To determine whether a powered ankle-foot orthosis (AFO) that provides dorsiflexor and plantar flexor assistance at the ankle can improve walking endurance of persons with multiple sclerosis (MS).

Design

Short-term intervention.

Setting

University research laboratory.

Participants

Participants (N=16) with a neurologist-confirmed diagnosis of MS and daily use of a prescribed custom unilateral passive AFO.

Interventions

Three 6-minute walk tests (6MWTs), 1 per footwear condition: shoes (no AFO), prescribed passive AFO, and portable powered AFO (PPAFO). Assistive devices were worn on the impaired limb.

Main Outcome Measures

Distance walked and metabolic cost of transport were recorded during each 6MWT and compared between footwear conditions.

Results

Each participant completed all three 6MWTs within the experimental design. PPAFO use resulted in a shorter 6MWT distance than did a passive AFO or shoe use. No differences were observed in metabolic cost of transport between footwear conditions.

Conclusions

The current embodiment of this PPAFO did not improve endurance walking performance during the 6MWT in a sample of participants with gait impairment due to MS. Further research is required to determine whether expanded training or modified design of this powered orthosis can be effective in improving endurance walking performance in persons with gait impairment due to MS.  相似文献

Objective

To provide a preliminary evaluation of the effectiveness of an online resource for job seekers with multiple sclerosis (MS).

Design

Randomized controlled design.

Setting

Community-dwelling cohort.

Participants

Adults (N = 95) with relapsing-remitting or progressive MS were randomly assigned to one of two groups. Forty-five accessed an email delivered, 7 module resource, Work and MS, over a 4 week period. Waitlist control participants (n=50) were offered the opportunity to access Work and MS 4 weeks postenrollment.

Main Outcome Measures

Primary outcomes focused on vocational interests (My Vocational Situation Scale) and self-efficacy in job-seeking activities (Job-Procurement Self Efficacy Scale). Secondary outcomes focused on perceived workplace difficulties (Multiple Sclerosis Work Difficulties Questionnaire [MSWDQ]), optimism (Life Orientation Test – Revised), and mood (Patient Health Questionnaire-9).

Results

Intention-to-treat analyses revealed pre-post gains: participants who accessed Work and MS reported improved confidence in their career goals (My Vocational Situation Scale g=.55; 95% confidence interval [CI], .14–.96; P=.008) and positively reappraised potential workplace difficulties (MSWDQ g range, .42–.47; P range, .023–.042). The effect on job self-efficacy was not significant, but changed in the expected direction (g=.17; 95% CI, –.23 to .57; P=.409). Completer data revealed larger, significant effect estimates (g range, .52–.64; P range, .009–.035).

Conclusions

Findings provide preliminary support for the utility of a job information resource, Work and MS, to augment existing employment services. The results also suggest the need to test employment-ready interventions in a larger study population. This might include the addition of online peer support to increase intervention compliance.  相似文献

Objective

To compare the effects of classic progressive resistance training (PRT) versus eccentric strength-enhanced training (EST) on the performance of functional tests and different strength manifestations in the lower limb of people with multiple sclerosis (PwMS).

Design

Experimental trial.

Setting

Strength training program.

Participants

PwMS (N=52; 19 men, 33 women) belonging to MS associations from the Castilla y León, Spain.

Interventions

Participants were assigned to 1 of 2 groups: a control group that performed PRT or an experimental group that performed EST. In both groups, the knee extensor muscles were trained for 12 weeks.

Main Outcome Measures

Before and after 12 weeks of training, maximal voluntary isometric contraction and 1 repetition maximum (1RM) of the knee extensors were evaluated, as were the Chair Stand Test (CST) and Timed 8-Foot Up and Go (TUG) functional tests.

Results

No differences were found between the groups in the initial values for different tests. Intragroup comparisons found significant differences in CST (F=69.4; P<.001), TUG (F=40.0; P<.001), and 1RM (F=57.8; P<.001). For intergroup comparisons, EST presented better results than PRT in the CST (EST, 4.7%±2.8%; PRT, 1.9%±2.8%; F=13.1; P=.001) and TUG (EST, ?2.9±4.7; PRT, ?.41±5.6; F=5.6; P=.022).

Conclusions

In PwMS, EST leads to improvements in 1RM, TUG, and CST that are similar to those of PRT. However, for patients who participated in this study, the EST seems to promote a better transfer of strength adaptations to the functional tests, which are closer to daily-living activities.  相似文献

Objective

To assess the diagnostic and clinical utility of the 2-item Generalized Anxiety Disorder Scale (GAD-2) for screening anxiety symptoms in individuals with multiple sclerosis (MS).

Design

Cross-sectional.

Setting

University-affiliated MS neurology and rehabilitation center.

Participants

The sample comprised adults (N=99) (ages 19-72; mean ± SD=46.2±13.0; 75% women) with a physician-confirmed MS diagnosis who were receiving care in a university-affiliated MS center. Disease durations ranged from 1 to 37 years (mean ± SD=10.7±8.4).

Interventions

Not applicable.

Main Outcome Measures

Participants completed the 7-item Generalized Anxiety Disorder Scale (GAD-7) and GAD-2. Internal consistency was calculated for both measures. Area under the receiver operating characteristics curve (AUC), the 95% confidence interval for the AUC, and Youden’s J were calculated to determine the optimal GAD-2 cutoff score for identifying clinically significant anxiety symptoms, as defined by the previously validated GAD-7 cutoff score of ≥8.

Results

Internal consistency was excellent for the GAD-7 (Cronbach α=.91) and acceptable for the GAD-2 (α=.77), and the measures were highly correlated (r=.94). The GAD-2 had excellent overall accuracy for identifying clinically significant anxiety symptoms (AUC=0.97; 95% confidence interval, 0.94-1.00). A GAD-2 cutoff score of ≥3 provided an optimal balance of good sensitivity (0.87) and excellent specificity (0.92) for detecting clinically significant anxiety symptoms. Alternatively, a cutoff score of ≥2 provided excellent sensitivity (1.00) and fair specificity (0.76).

Conclusions

The GAD-2 is a clinically useful and psychometrically valid tool for screening anxiety symptoms in MS rehabilitation and neurology care settings. Importantly, this tool has the potential to identify individuals with MS who are at risk for anxiety disorders and who may benefit from rehabilitation psychology interventions to ultimately improve functioning and quality of life.  相似文献

Objective

To determine the extent to which the content of the Quality of Life in Neurological Disorders (Neuro-QoL) covers the International Classification of Functioning, Disability and Health (ICF) Core Sets for multiple sclerosis (MS), stroke, spinal cord injury (SCI), and traumatic brain injury (TBI) using summary linkage indicators.

Design

Content analysis by linking content of the Neuro-QoL to corresponding ICF codes of each Core Set for MS, stroke, SCI, and TBI.

Setting

Three academic centers.

Participants

None.

Interventions

None.

Main Outcome Measures

Four summary linkage indicators proposed by MacDermid et al were estimated to compare the content coverage between Neuro-QoL and the ICF codes of Core Sets for MS, stroke, MS, and TBI.

Results

Neuro-QoL represented 20% to 30% Core Set codes for different conditions in which more codes in Core Sets for MS (29%), stroke (28%), and TBI (28%) were covered than those for SCI in the long-term (20%) and early postacute (19%) contexts. Neuro-QoL represented nearly half of the unique Activity and Participation codes (43%–49%) and less than one third of the unique Body Function codes (12%?32%). It represented fewer Environmental Factors codes (2%?6%) and no Body Structures codes. Absolute linkage indicators found that at least 60% of Neuro-QoL items were linked to Core Set codes (63%?95%), but many items covered the same codes as revealed by unique linkage indicators (7%?13%), suggesting high concept redundancy among items.

Conclusions

The Neuro-QoL links more closely to ICF Core Sets for stroke, MS, and TBI than to those for SCI, and primarily covers activity and participation ICF domains. Other instruments are needed to address concepts not measured by the Neuro-QoL when a comprehensive health assessment is needed.  相似文献

Objective

To identify preoperative risk factors associated with posthospitalization falls over an approximate 2-year postoperative period in patients undergoing both hip and knee arthroplasty.

Design

A longitudinal cohort design.

Setting

Communities surrounding 4 urban university–based medical centers.

Participants

Adults (N = 596) with hip or knee arthroplasty over a 9-year period and followed yearly.

Interventions

Not applicable.

Main Outcome Measures

The primary outcome measure was a self-reported history of falls over the 2-year postoperative period. A fall was recorded when the participant reported landing on the floor or ground. Preoperative predictors of falls derived from previous evidence included preoperative fall history, depressive symptom severity, narcotic use, age, activity level, and comorbidity. Multinomial regression analysis was performed to determine factors that predicted either a single fall or multiple falls during a 2-year postoperative period.

Results

Preoperative predictors of multiple postoperative falls were a preoperative history of falls, depressive symptoms, and hip vs knee arthroplasty. Patients with hip arthroplasty were more than twice as likely (odds ratio, 2.26; 95% confidence interval, 1.21–4.20) as patients with knee arthroplasty to have multiple self-reported falls in the first 2 postoperative years. No predictors were found for persons who reported falling only once postoperatively. Findings were generally supported in a sensitivity analysis.

Conclusions

Clinicians involved in the pre- and postoperative care of persons undergoing hip or knee arthroplasty can use these findings to inform fall risk screening and intervention delivery to reduce fall risk in patients who are at risk for multiple falls after hip or knee arthroplasty.  相似文献

Background

Employment in those with disability is an important rehabilitation goal, along with achieving some measure of functional independence and is at the same time one of the most difficult goals to achieve. The number of people with disabilities participating in adaptive sports has been increasing steadily over the years. A few studies have looked at the relationship between physical fitness and employment status in those with disability, but there have been no studies that focused on the results of organized adaptive sports events affecting employment outcome.

Objective

To determine whether participation in the National Veterans Wheelchair Games (NVWG) has a positive impact on employment in those with disability.

Study Design

Prospective, cross-sectional survey.

Setting

2015 NVWG in Dallas, Texas (nonclinic setting).

Participants

A total of 338 survey participants; 36 surveys were excluded due to incompletion.

Methods

Veterans who participated at the 2015 NVWG were given the opportunity to complete a 2-page survey. Survey participants received $5.00 gift card as compensation.

Main Outcome Measurements

Percentage of those who perceived NVWG made a difference in attaining employment, risk ratio analyses.

Results

A total of 50% of the participants stated that the NVWG made a difference in attaining employment. Those currently working were 1.5 times more likely to say that the NVWG had a positive effect on employment than those not currently working (P < .01). Those who felt that the NVWG had a positive effect on employment attended 3-4 more wheelchair games on average than those reporting that the NVWG did not have an impact on employment (P < .001). Positive responses were obtained from the Likert scale distribution.

Conclusions

Our study suggests that participating in the NVWG provides psychosocial support to the veterans and may have a positive influence in employment outcomes.

Objective

To examine the safety and efficacy of using a clitoral vacuum suction device (CVSD) versus vibratory stimulation (V) to treat orgasmic dysfunction in women with multiple sclerosis (MS) or spinal cord injury (SCI).

Design

Randomized clinical trial.

Setting

Two academic medical centers.

Participants

Women (N=31) including 20 with MS and 11 with SCI.

Intervention

A 12-week trial of the use of a CVSD versus V.

Main Outcome Measures

Female Sexual Function Inventory (FSFI) and Female Sexual Distress Scale (FSDS).

Results

Twenty-three women (18 MS, 5 SCI) completed the study including 13 of 16 randomized to CVSD and 10 of 15 randomized to V. There was a statistically significant increase in total FSFI score (P=.011), desire (P=.009), arousal (P=.009), lubrication (P=.008), orgasm (P=.012), and satisfaction (P=.049), and a significant decrease in distress as measured by FSDS (P=.020) in subjects using the CVSD. In subjects who used V, there was a statistically significant increase in the orgasm subscale of the FSFI (P=.028). Subjects using the CVSD maintained improvements 4 weeks after treatment.

Conclusions

CVSD is safe and overall efficacious to treat female neurogenic sexual dysfunction related to MS and SCI. V is also safe and efficacious for female neurogenic orgasmic dysfunction; however, results were limited to the active treatment period. Because of ease of access and cost, clinicians can consider use of V for women with MS or SCI with orgasmic dysfunction. CVSD is recommended for women with multiple sexual dysfunctions or for whom V is ineffective.  相似文献

Objective

To examine self-regulation strategies as correlates of physical activity in persons with multiple sclerosis (MS).

Design

Cross-sectional, or survey, study.

Setting

University-based research laboratory.

Participants

Convenience sample of persons with MS (N=68).

Interventions

Not applicable.

Main Outcome Measures

Exercise Self-Efficacy Scale (EXSE), 12-item Physical Activity Self-Regulation Scale (PASR-12), and Godin Leisure-Time Exercise Questionnaire (GLTEQ).

Results

Correlation analyses indicated that GLTEQ scores were positively and significantly associated with overall self-regulation (r=.43), self-monitoring (r=.45), goal-setting (r=.27), reinforcement (r=.30), time management (r=.41), and relapse prevention (r=.53) PASR-12 scores. Regression analyses indicated that relapse prevention (B=5.01; SE B=1.74; β=.51) and self-monitoring (B=3.65; SE B=1.71; β=.33) were unique predictors of physical activity behavior, and relapse prevention demonstrated a significant association with physical activity behavior that was accounted for by EXSE.

Conclusions

Our results indicate that self-regulatory strategies, particularly relapse prevention, may be important correlates of physical activity behavior that can inform the design of future behavioral interventions in MS.  相似文献

Background

We reported previously that young men with chronic spinal cord injury (SCI) have a greater prevalence of testosterone deficiency compared with an age-matched, healthy control population. Young men with SCI also are at increased risk for developing cardiometabolic dysfunction after injury. It is unclear whether testosterone deficiency is associated with heightened cardiometabolic risk in men with SCI.

Objective

To investigate associations among levels of testosterone in young men with chronic SCI and surrogate markers of cardiometabolic risk.

Design

Secondary cross-sectional analysis.

Setting

Rehabilitation research centers in Washington, DC, and Miami, Florida.

Participants

Men (n = 58) aged 18-45 years with chronic (≥1 year), motor complete SCI without comorbidities or use of testosterone therapy.

Methods

Plasma concentrations of testosterone, lipids, inflammatory markers (C-reactive protein and interleukin-6), percent hemoglobin A1c, glucose, and insulin were measured in a fasting state using standard assays. A 2-hour oral glucose tolerance test and Framingham Risk Score were assessed for each subject. Body composition was assessed by dual X-ray absorptiometry scan.

Main Outcome Measurements

Surrogate markers of cardiometabolic risk among men based on the level of total testosterone (TT; ≤300, 301-500, or >500 ng/dL) and free testosterone (fT; ≤9 or >9 ng/dL). Comparisons were made between men with normal and low TT or fT.

Results

Framingham Risk Score was significantly greater in men with low fT (P < .05). Percent body fat (P < .05) and waist-to-hip ratio (P < .05) but not body mass index (P > .08), were greater in men with low TT or low fT. Men with low TT or low fT had lower high-density lipoprotein cholesterol levels (P < .05) without differences in fasting triglycerides (P > .1) or low-density lipoprotein cholesterol (P > .07). Men with low TT had greater levels of inflammatory markers C-reactive protein (P < .05) and interleukin-6 (P < .05). Men with low TT or low fT had greater fasting glucose (P < .05) and greater insulin resistance (P < .04), without differences in percent hemoglobin A1c (P > .8).

Conclusions

In young men with chronic SCI who undergo an accelerated aging process postinjury, hypogonadism is associated with an unfavorable cardiometabolic risk profile. Further research is needed to determine whether a causal relationship exists between hypogonadism and heightened cardiometabolic risk in men with SCI and whether routine screening for testosterone deficiency is warranted in this population.

Objective

To verify the effects of structured home-based exercises without supervision by a physical therapist in patients with early-stage amyotrophic lateral sclerosis (ALS).

Design

A historical controlled study that is part of a multicenter collaborative study.

Setting

Rehabilitation departments at general hospitals and outpatient clinics with a neurology department.

Participants

Patients (N=21) with ALS were enrolled and designated as the home-based exercise (Home-EX) group, and they performed unsupervised home-based exercises. As a control group, 84 patients with ALS who underwent supervised exercise with a physical therapist for 6 months were extracted from a database of patients with ALS and matched with the Home-EX group in terms of their basic attributes and clinical features.

Intervention

The Home-EX group was instructed to perform structured home-based exercises without supervision by a physical therapist that consisted of muscle stretching, muscle training, and functional training for 6 months.

Main Outcome Measures

The primary outcome was the score on the ALS Functional Rating Scale–Revised (ALSFRS-R), which is composed of 3 domains: bulbar function, limb function, and respiratory function. The score ranges from 0 to 48 points, with a higher score indicating better function.

Results

In the Home-EX group, 15 patients completed the home-based exercises for 6 months, and 6 patients dropped out because of medical reasons or disease progression. No adverse events were reported. The Home-EX group was found to have a significantly higher respiratory function subscore and total score on the ALSFRS-R than the control group at follow-up (P<.001 and P<.05, respectively).

Conclusions

Structured home-based exercises without supervision by a physical therapist could be used to alleviate functional deterioration in patients with early-stage ALS.  相似文献

Objectives

To (1) examine and compare dual-task performance in patients with multiple sclerosis (MS) and healthy controls (HCs) using mathematical problem-solving questions that included an everyday competence component while performing an upper extremity fine motor task; and (2) examine whether difficulties in dual-task performance are associated with problems in performing an everyday internet task.

Design

Pilot study, mixed-design with both a within and between subjects' factor.

Setting

A nonprofit rehabilitation research institution and the community.

Participants

Participants (N=38) included persons with MS (n=19) and HCs (n=19) who were recruited from a nonprofit rehabilitation research institution and from the community.

Interventions

Not applicable.

Main Outcome Measures

Participant were presented with 2 testing conditions: (1) solving mathematical everyday problems or placing bolts into divots (single-task condition); and (2) solving problems while putting bolts into divots (dual-task condition). Additionally, participants were required to perform a test of everyday internet competence.

Results

As expected, dual-task performance was significantly worse than either of the single-task tasks (ie, number of bolts into divots or correct answers, and time to answer the questions). Cognitive but not motor dual-task cost was associated with worse performance in activities of everyday internet tasks.

Conclusions

Cognitive dual-task cost is significantly associated with worse performance of everyday technology. This was not observed in the motor dual-task cost. The implications of dual-task costs on everyday activity are discussed.  相似文献

Objectives

To determine the efficacy of a web-based transfer training module at improving transfer technique across 3 groups: web-based training, in-person training (current standard of practice), and a waitlist control group (WLCG); and secondarily, to determine subject factors that can be used to predict improvements in transfer ability after training.

Design

Randomized controlled trials.

Setting

Summer and winter sporting events for disabled veterans.

Participants

A convenience sample (N=71) of manual and power wheelchair users who could transfer independently.

Interventions

An individualized, in-person transfer training session or a web-based transfer training module. The WLCG received the web training at their follow-up visit.

Main Outcome Measure

Transfer Assessment Instrument (TAI) part 1 score was used to assess transfers at baseline, skill acquisition immediately posttraining, and skill retention after a 1- to 2-day follow-up period.

Results

The in-person and web-based training groups improved their median (interquartile range) TAI scores from 7.98 (7.18–8.46) to 9.13 (8.57–9.58; P<.01), and from 7.14 (6.15–7.86) to 9.23 (8.46–9.82; P<.01), respectively, compared with the WLCG that had a median score of 7.69 for both assessments (baseline, 6.15–8.46; follow-up control, 5.83–8.46). Participants retained improvements at follow-up (P>.05). A lower initial TAI score was found to be the only significant predictor of a larger percent change in TAI score after receiving training.

Conclusions

Transfer training can improve technique with changes retained within a short follow-up window, even among experienced wheelchair users. Web-based transfer training demonstrated comparable improvements to in-person training. With almost half of the United States population consulting online resources before a health care professional, web-based training may be an effective method to increase knowledge translation.  相似文献
