Black-white differences in patient characteristics, treatments, and outcomes in inpatient stroke rehabilitation

Horn SD, Deutscher D, Smout RJ, DeJong G, Putman K. Black-white differences in patient characteristics, treatments, and outcomes in inpatient stroke rehabilitation.

Objective

To describe racial differences in patient characteristics, nontherapy ancillaries, physical therapy (PT), occupational therapy (OT), and functional outcomes at discharge in stroke rehabilitation.

Design

Multicenter prospective observational cohort study of poststroke rehabilitation.

Setting

Six U.S. inpatient rehabilitation facilities.

Participants

Black and white patients (n=732), subdivided in case-mix subgroups (CMGs): CMGs 104 to 107 for moderate strokes (n=397), and CMGs 108 to 114 for severe strokes (n= 335).

Interventions

Not applicable.

Main Outcome Measure

FIM.

Results

Significant black-white differences in multiple patient characteristics and intensity of rehabilitation care were identified. White subjects took longer from stroke onset to rehabilitation admission and were more ambulatory prior to stroke. Black subjects had more diabetes. For patients with moderate stroke, black subjects were younger, were more likely to be women, and had more hypertension and obesity with body mass index greater than or equal to 30. For patients with severe stroke, black subjects were less sick and had higher admission FIM scores. White subjects received more minutes a day of OT, although black subjects had significantly longer median PT and OT session duration. No black-white differences in unadjusted stroke rehabilitation outcomes were found.

Conclusions

Reasons for differences in rehabilitation care between black and white subjects should be investigated to understand clinicians' choice of treatments by race. However, we did not find black-white differences in unadjusted stroke rehabilitation outcomes.     

Land-Based Versus Pool-Based Exercise for People Awaiting Joint Replacement Surgery of the Hip or Knee: Results of a Randomized Controlled Trial

Gill SD, McBurney H, Schulz DL. Land-based versus pool-based exercise for people awaiting joint replacement surgery of the hip or knee: results of a randomized controlled trial.

Objective

To compare the preoperative effects of multidimensional land-based and pool-based exercise programs for people awaiting joint replacement surgery of the hip or knee.

Design

Randomized, single-blind, before-after trial.

Setting

Physiotherapy gymnasium and hydrotherapy pool.

Participants

Patients awaiting elective hip or knee joint replacement surgery.

Interventions

Land-based (n=40) or pool-based exercise program (n=42). Each 6-week program included an education session, twice-weekly exercise classes, and an occupational therapy home assessment.

Main Outcome Measures

Participants were assessed immediately before and after the 6-week intervention, then 8 weeks later. Primary outcomes were pain and self-reported function (Western Ontario and McMaster Universities Osteoarthritis Index) and patient global assessment. Secondary outcomes were performance-based measures (timed walk and chair stand) and psychosocial status (Medical Outcomes Study 36-Item Short-Form Health Survey mental component score). Pain was also measured before and after each exercise class on a 7-point verbal rating scale.

Results

Although both interventions were effective in reducing pain and improving function, there were no postintervention differences between the groups for the primary and secondary outcomes. However, the pool-based group had less pain immediately after the exercise classes.

Conclusions

While our multidimensional exercise-based interventions appeared to be effective in reducing disability in those awaiting joint replacement surgery of the hip or knee, there were no large differences in the postintervention effects of the interventions. However, pool-based exercise appeared to have a more favorable effect on pain immediately after the exercise classes.     

Self-Management Improves Outcomes in Persons With Limb Loss

Wegener ST, Mackenzie EJ, Ephraim P, Ehde D, Williams R. Self-management improves outcomes in persons with limb loss.

Objective

To test the acceptance and effectiveness of a community-based self-management (SM) intervention designed to improve outcomes after limb loss. A priori hypothesis was that an SM intervention will be more effective than standard support group activities in improving outcomes.

Design

Randomized controlled trial.

Setting

General community.

Participants

Intervention (N=287) and control participants (N=235) with major limb loss.

Intervention(s)

Nine, 90-minute SM group sessions delivered by trained volunteer leaders. Retention rates at immediate postintervention and 6-month follow-up were 97% and 91% for the SM group.

Main Outcome Measure(s)

Primary outcomes were depression, positive mood, and self-efficacy. Secondary outcomes were improved functional status and quality of life.

Results

By using intent-to-treat analyses, the odds for being depressed are significantly lower for those in SM group, 50% less likely at treatment completion (95% confidence interval [CI]=0.3-0.9) and 40% less likely at the 6-month follow-up (95% CI=.03-1.1). Treatment completers have a 70% reduction in likelihood of being depressed at posttreatment (P<.01) and this persists at six months (P<.05). For those in the SM group, functional limitations were significantly lower at 6 months (P<.05), and general self-efficacy was significantly higher at immediate posttreatment (P<.05) and at 6 months (P<.05). Treatment completers have generally significantly larger effect sizes at all follow-up points. Pain intensity, self-efficacy for pain control, and quality of life were not significantly different between the groups. Subgroup analyses indicated the impact of the intervention was greater for participants who were less than 3 years postamputation, participants who were less than 65 years of age, or participants who showed at least 1 secondary condition at baseline.

Conclusions

The study provides evidence that SM interventions can improve the outcomes of persons with limb loss beyond benefits offered by support groups.     

Goals of physiotherapy interventions can be described using the International Classification of Functioning, Disability and Health

Objective

To provide an example of how goals of physiotherapy interventions and their typical patterns can be described using the International Classification of Functioning, Disability and Health (ICF).

Design

Cross-sectional study.

Setting

Acute hospital.

Participants

One hundred patients with neurological, musculoskeletal or cardiopulmonary conditions requiring physiotherapy interventions in University Hospital Zurich between January 2003 and October 2003.

Main outcome measures

The case record form consisted of two parts: a standardised questionnaire for functioning and health of the patient; and a standardised record form for physiotherapy interventions. Both parts were based on the ICF.

Results

The mean age of the subjects was 58.2 years (standard deviation 15.9), the median age was 60.5 years and 44% were female. The most frequent intervention goals in patients with neurological conditions were: muscle power functions; muscle tone functions; control of voluntary movement functions; changing basic body position; maintaining a body position; and transferring oneself. The most frequent intervention goals for cardiopulmonary patients were: functions of the cardiovascular system; and respiration functions. The most frequent intervention goals in patients with musculoskeletal conditions were: sensation of pain; stability of joint functions; muscle power functions; muscle tone functions; and muscle endurance functions.

Conclusion

By using the ICF as a framework and linguistic support, intervention goals can serve as standardised documentation for physiotherapy interventions, their evaluation and planning.     

The effectiveness of massage with and without dimethyl sulfoxide in preventing pressure ulcers: a randomized, double-blind cross-over trial in patients prone to pressure ulcers

Background

Although guidelines advise against massage, it is one of the methods widely regarded and used by nurses to prevent pressure ulcers (PU).

Objectives

The purpose of this study was to examine the effectiveness of different variations of massage in preventing pressure ulcers.

Methods

A randomized, double-blind cross-over design, in which patients of nursing homes who are prone to PU underwent two of the three possible interventions; ‘position changes only’, ‘massaging with an indifferent cream’ and ‘massaging with a dimethyl sulfoxide (DMSO) cream’.

Results

The results of three interventions did not differ significantly. DMSO did not fulfil the expectations raised by literature and a previous pilot-study.     

A randomized clinical trial of an activity and exercise adherence intervention in chronic pulmonary disease

Steele BG, Belza B, Cain KC, Coppersmith J, Lakshminarayan S, Howard J, Haselkorn JK. A randomized clinical trial of an activity and exercise adherence intervention in chronic pulmonary disease.

Objectives

To evaluate the effectiveness of an exercise adherence intervention to maintain daily activity, adherence to exercise, and exercise capacity over 1 year after completion of an outpatient pulmonary rehabilitation program.

Design

A 2-group, experimental design was used with randomization into intervention and usual care groups.

Setting

Outpatient pulmonary rehabilitation program in a university-affiliated medical center.

Participants

One hundred six subjects (98 men; 98 with chronic obstructive pulmonary disease) with a mean age of 67 years and chronic lung disease.

Intervention

Twelve-week adherence intervention (weekly phone calls and home visit) including counseling on establishing, monitoring, and problem-solving in maintaining a home exercise program.

Main Outcome Measures

Primary outcomes included daily activity (accelerometer), exercise adherence (exercise diary), and exercise capacity (six-minute walk test). All measures were performed at baseline, after the pulmonary rehabilitation program (8wk), after the adherence intervention (20wk), and at 1 year.

Results

A rank-based analysis of covariance showed less decline at 20 weeks in exercise adherence (intervention mean, +3min; control mean, −13min; P=.015) and exercise capacity (intervention mean, −10.7m; control mean, −35.4m; P=.023). There were no differences in daily activity at 20 weeks or any differences in any primary variable at 1 year.

Conclusions

The intervention enhanced exercise adherence and exercise capacity in the short term but produced no long-term benefit. These findings are in part attributed to the disappointing measurement characteristics of the accelerometer used to measure daily activity. The intervention was acceptable to participants. Further study is needed to fashion interventions that have more persistent benefit.     

Comparison of Trunk Proprioception Between Patients With Low Back Pain and Healthy Controls

Lee AS, Cholewicki J, Reeves NP, Zazulak BT, Mysliwiec LW. Comparison of trunk proprioception between patients with low back pain and healthy controls.

Objective

To determine whether proprioceptive impairments exist in patients with low back pain (LBP). We hypothesized that patients with LBP would exhibit larger trunk proprioception errors than healthy controls.

Design

Case-control study.

Setting

University laboratory.

Participants

24 patients with nonspecific LBP and 24 age-matched healthy controls.

Interventions

Not applicable.

Main Outcome Measures

We measured trunk proprioception in all 3 anatomical planes using motion perception threshold, active repositioning, and passive repositioning tests.

Results

LBP patients had significantly greater motion perception threshold than controls (P<.001) (1.3±0.9° vs 0.8±0.6°). Furthermore, all subjects had the largest motion perception threshold in the transverse plane (P<.001) (1.2±0.7° vs 1.0±0.8° for all other planes averaged). There was no significant difference between LBP and healthy control groups in the repositioning tasks. Errors in the active repositioning test were significantly smaller than in the passive repositioning test (P=.032) (1.9±1.2° vs 2.3±1.4°).

Conclusions

These findings suggest that impairments in proprioception may be detected in patients with LBP when assessed with a motion perception threshold measure.     

Do smokers with chronic obstructive pulmonary disease report their smoking status reliably? A comparison of self-report and bio-chemical validation

Background

Chronic obstructive pulmonary disease (COPD) is predominantly caused by cigarette smoking and is considered a worldwide preventable chronic illness. Smoking cessation is considered the primary intervention for disease management and nurses should play a major role in assisting patients to stop smoking. Currently there is a lack of professional consensus on how cessation interventions should be evaluated. The vast array of biochemical markers reported in the literature can be confusing and can make the comparisons of results difficult.

Objective

To validate self-report data on smoking with exhaled carbon monoxide in patients with chronic obstructive pulmonary disease over twelve months.

Design

We performed a secondary analysis of a previously published randomized controlled trial evaluating nursing interventions to assist respiratory patients to stop smoking.

Setting

Northern Ireland's Regional Respiratory Centre.

Participants

A total of 91 cigarette smokers attending secondary care for the treatment for COPD participated in the study.

Method

Self-reported smoking status and cigarettes smoked per day were compared to exhaled carbon monoxide readings at baseline, 2, 3, 6, 9 and 12 months. The cut-off value of ≤10 ppm was used to identify non-smokers. The p-values are based on Pearson's correlation coefficient and Kappa Coefficient as appropriate.

Results

Findings suggest self-reported smoking status and cigarette consumption amongst patients with chronic obstructive pulmonary disease was highly consistent with exhaled carbon monoxide results (p = 0.001-0.003).

Conclusion

The majority of patients with chronic obstructive pulmonary disease reliably report their cigarette consumption.     

The impact of limitations in physical, executive, and emotional function on health-related quality of life among adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

Ness KK, Gurney JG, Zeltzer LK, Leisenring W, Mulrooney DA, Nathan PC, Robison LL, Mertens AC. The impact of limitations in physical, executive, and emotional function on health-related quality of life among adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study.

Objective

To examine associations between limitations in physical performance, executive function, and emotional health (activity domains) and either social role attainment or health-related quality of life (HRQOL) in adult survivors of childhood cancer.

Design

Cross-sectional analysis.

Setting

Cancer survivors living in the community; previously treated for childhood cancer at one of 26 institutions.

Participants

Subjects included 7147 (76.8%) of 9307 eligible adult members of the Childhood Cancer Survivor Study who completed a follow-up questionnaire between 2002 and 2004.

Interventions

Not applicable.

Main Outcome Measures

Demographic information was used to classify social roles and the Medical Outcomes Survey 36-Item Short-Form Health Survey to ascertain HRQOL. Questions from the National Health Interview Survey were used to represent physical performance; from the Brief Symptom Inventory to classify emotional health; and from the Behavioral Rating of Executive Function to describe executive function. Multivariate logistic regression was used to examine the association between limitations in activity domains, role attainment, and HRQOL.

Results

In this cohort, 18.1% reported deficits in physical performance, 10.5% in emotional health, and 14.0% in executive function. In adjusted models, when compared with survivors who reported no limitations, those with physical performance, executive function, or emotional health deficits were less likely to be employed, married, or have incomes greater than $20,000 a year. Limitations in executive function or emotional health were associated with no health insurance. Limitations in any activity domain were associated with poor HRQOL. Emotional health limitations had the most impact, with odds ratios from 3.18 (physical performance summary) to 25.81 (mental health).

Conclusions

The results of these analyses show the need for development and testing of interventions to remediate limitations in activity domains, because they negatively impact role attainment and HRQOL.     

Paraplegia after aortic aneurysm repair versus traumatic spinal cord injury: functional outcome, complications, and therapy intensity of inpatient rehabilitation

Yokoyama O, Sakuma F, Itoh R, Sashika H. Paraplegia after aortic aneurysm repair versus traumatic spinal cord injury: functional outcome, complications, and therapy intensity of inpatient rehabilitation.

Objective

To compare outcomes, complications, and therapy intensity of inpatient rehabilitation in patients with paraplegia caused by spinal cord injury associated with aortic aneurysm repair (SCI-AA) versus patients with traumatic spinal cord injury (SCI).

Design

Case-controlled study.

Setting

SCI unit in a rehabilitation center.

Participants

Seventeen patients with SCI-AA and 17 patients with traumatic SCI.

Intervention

Standard rehabilitation therapy for SCI.

Main Outcome Measures

Length of stay (LOS) in acute and rehabilitation hospitals; FIM instrument scores; FIM change; FIM efficiency; complications; therapy intensity; and ambulatory state and return to community at discharge.

Results

No significant differences were noted in acute and rehabilitation LOS and admission FIM scores. Discharge FIM scores, FIM change, and FIM efficiencies were significantly lower in the SCI-AA group, which had many complications related to AA and SCI. Intensity of rehabilitation sports therapy in the SCI-AA group was significantly lower than that of the traumatic SCI group, but total therapy intensity did not differ significantly. Both had similar rates of return to ambulatory state and discharge to the community.

Conclusions

SCI-AA patients had many complications that interfered with rehabilitation therapy, and could not achieve functional gains comparable to those with traumatic SCI. However, both groups achieved comparable success with return to ambulatory state and discharge to the community.     

Relatives' Criticism Influences Adjustment and Outcome After Traumatic Brain Injury

Weddell RA. Relatives' criticism influences adjustment and outcome after traumatic brain injury.

Objectives

To apply some of the methods developed to study the effects of relatives' expressed emotion (EE) on psychiatric relapse rates and to test the prediction that relatives' criticism and psychiatric distress would be associated with outcome and emotional distress after traumatic brain injury (TBI).

Design

Retrospective cohort design with correlational analyses of quantitative and qualitative measures of TBI outcomes.

Setting

The author interviewed participants in the hospital. The research assistant interviewed close relatives at home.

Participants

Participants and relatives (N=78) were interviewed 34.3±15.2 months (mean ± SD) after a severe TBI.

Interventions

None.

Main Outcome Measures

Dependent variables in a series of hierarchical linear regression models were participants' scores on the Zung Depression Scale, Spielberger Trait Anxiety Inventory, State-Trait Anger Expression Inventory, an Anger Towards Relative questionnaire constructed for this study, and Extended Glasgow Outcome Scores. Participant-independent variables were social class, posttraumatic amnesia, Wechsler Memory Scale-Delayed Recall score, WAIS-R intelligence quotient, and a short version of the Smell Identification Test. Relative independent variables were the number of critical comments directed toward participants in the interview and psychiatric distress as measured by the General Health Questionnaire.

Results

The contributions of variance associated with relative independent variables (predominantly criticism) were significant in stage 2 of most hierarchical regression analyses after the adjustments for variance associated with participant independent variables made in stage 1.

Conclusions

Future application of EE research methods is warranted. If the present results are replicated, then evidence-based family interventions developed by EE researchers to reduce criticism might also improve TBI outcomes.     

Structural Equation Modeling of the Relationships Between Participation in Leisure Activities and Community Environments by People With Mobility Impairments

Hollingsworth H, Gray DB. Structural equation modeling of the relationships between participation in leisure activities and community environments by people with mobility impairments.

Objective

To examine the linkages between the constructs of participation and the environment for a set of leisure activities (attending concerts, attending movies, attending sporting events).

Design

Self-report surveys of the influence of the environment on participation were analyzed using structural equation modeling. Temporal, evaluative, and health-related aspects of leisure activities were selected as latent variables associated with participation. The environmental construct consisted of the latent variables of the influence on participation of the natural, interpersonal, built, background, and supportive environments.

Setting

Midwestern United States.

Participants

A purposive sample of people (N=604) with mobility limitations.

Intervention

None.

Main Outcome Measures

Measures of relationships between participation in leisure activities and the environment of people with mobility limitations.

Results

Structural equation modeling can be an important tool for empirically examining the contributions of the component latent variables of participation and the environment.

Conclusions

A model that fits participation by people with disabling conditions in their environment can provide guidance for community-based interventions and person-based therapies.     

Measuring Participation as Defined by the International Classification of Functioning, Disability and Health: An Evaluation of Existing Measures

Resnik L, Plow M. Measuring participation as defined by the International Classification of Functioning, Disability and Health: an evaluation of existing measures.

Objectives

The content and theoretic underpinning of measures designed to assess participation, disability, and handicap vary widely, and few authors have attempted to compare the content of existing measures. The objectives of this study were to use the International Classification of Functioning, Disability and Health (ICF) taxonomy to (1) evaluate the participation content of measures and (2) identify the most comprehensive measures.

Design

We searched PubMed, Cumulated Index of Nursing and Allied Health Literature, and Health and Psychosocial Instruments databases to identify appropriate measures. Content analysis was conducted by classifying participation-related items of each measure into 1 or more of the 9 activities and participation chapters of the ICF taxonomy.

Setting

Not applicable.

Participants

We evaluated 40 generic and condition-specific self-report measures that met study inclusion criteria.

Interventions

Not applicable.

Main Outcome Measures

The most comprehensive measures were identified and coded by using second- and third-level ICF codes.

Results

Five measures containing participation items linked to all 9 chapters were the Community Living Skills Scale, the Assessment of Life Habits, Mayo-Portland Adaptability Inventory, the participation measure for postacute care, and the Psychosocial Adjustment to Illness Scale. The breadth and coverage of these 5 measures were compared.

Conclusions

We identified 5 measures that had items that were linkable to all 9 chapters of activities and participation; however, these measures differed in specifics of coverage and the approach to assessing participation. These findings can be used by clinicians and researchers to select the most comprehensive participation outcome measure for their populations.     

Long-term clinical benefits and costs of an integrated rehabilitation programme compared with outpatient physiotherapy for chronic knee pain

Background

Chronic knee pain is a major cause of disability in the elderly. Management guidelines recommend exercise and self-management interventions as effective treatments. The authors previously described a rehabilitation programme integrating exercise and self-management [Enabling Self-management and Coping with Arthritic knee Pain through Exercise (ESCAPE-knee pain)] that produced short-term improvements in pain and physical function, but sustaining these improvements is difficult. Moreover, the programme is untried in clinical environments, where it would ultimately be delivered.

Objectives

To establish the feasibility of ESCAPE-knee pain and compare its clinical effectiveness and costs with outpatient physiotherapy.

Design

Pragmatic, randomised controlled trial.

Setting

Outpatient physiotherapy department and community centre.

Participants

Sixty-four people with chronic knee pain.

Interventions

Outpatient physiotherapy compared with ESCAPE-knee pain.

Outcomes

The primary outcome was physical function assessed using the Western Ontario and McMaster Universities Osteoarthritis Index. Secondary outcomes included pain, objective functional performance, anxiety, depression, exercise-related health beliefs and healthcare utilisation. All outcomes were assessed at baseline and 12 months after completing the interventions (primary endpoint). ANCOVA investigated between-group differences.

Results

Both groups demonstrated similar improvements in clinical outcomes. Outpatient physiotherapy cost £130 per person and the healthcare utilisation costs of participants over 1 year were £583. The ESCAPE-knee pain programme cost £64 per person and the healthcare utilisation costs of participants over 1 year were £320.

Conclusions

ESCAPE-knee pain can be delivered as a community-based integrated rehabilitation programme for people with chronic knee pain. Both ESCAPE-knee pain and outpatient physiotherapy produced sustained physical and psychosocial benefits, but ESCAPE-knee pain cost less and was more cost-effective.Clinical Trial Registration No.: ISRCTN63848242.     

Gender differences in patient perceptions of involvement in myocardial infarction care

Background

Gender differences in the clinical presentation, treatment and outcomes of myocardial infarction (MI) have been demonstrated. However, few studies have examined gender differences in patients' perceptions of involvement in MI care, and whether differing levels of involvement might be associated with gender differences in treatment and outcome.

Aim

To examine possible gender differences in MI patients' perceptions of their involvement during hospitalization.

Methods

Questionnaire study conducted in 2005-2006 among MI patients under the age of 75 at eleven hospitals. Patient ratings of their involvement during hospitalization were analyzed for age-stratified gender differences.

Results

Younger (< 70 years of age) female MI patients placed significantly more value on shared decision-making than younger (< 70) men. More than one third of patients would have liked to be more involved in their care during hospitalization and discharge planning, with women significantly more dissatisfied than men. Significantly fewer younger female patients discussed secondary preventive lifestyle changes with cardiology staff prior to hospital discharge.

Conclusion

Significant age-specific gender differences exist in MI patient ratings of, and satisfaction with, involvement during hospitalization. Further study is needed regarding the possible role of involvement in the recognized gender differences in the treatment and outcomes of MI.     

Activation of lumbar paraspinal and abdominal muscles during therapeutic exercises in chronic low back pain patients

Arokoski JP, Valta T, Kankaanpää M, Airaksinen O. Activation of lumbar paraspinal and abdominal muscles during therapeutic exercises in chronic low back pain patients. Arch Phys Med Rehabil 2004;85:823-32.

Objectives

To assess the activities of paraspinal and abdominal muscles during therapeutic exercises for the treatment of patients with nonspecific chronic low back pain (CLBP), and to study the effects of active physical rehabilitation on these activities.

Design

A cross-sectional study comparing muscle activities during 18 stabilization exercises, and a prospective follow-up of patients with CLBP during rehabilitation.

Setting

Rehabilitation clinic in university hospital in Finland.

Participants

Nine volunteers (5 men, 4 women) aged 27 to 58 years.

Intervention

Three months of active outpatient rehabilitation (4 to 6 times in a rehabilitation clinic, supplemented with self-motivated exercise at home) supervised by a physiotherapist.

Main outcome measures

Surface electromyography was recorded bilaterally from L5 level paraspinal, rectus abdominis, and obliquus externus abdominis muscles. The recorded signal was averaged and normalized to the maximal electromyographic amplitude obtained during the maximal voluntary contraction. The measurements were taken before and after the exercise treatment period.

Results

CLBP patients showed variable trunk muscle activity patterns during the different therapeutic exercises, similar to those that we reported earlier in healthy subjects. The maximal trunk isometric extension (pre, 147.3±75.9Nm; post, 170.1±72.3Nm) and flexion (pre, 72.0±37.9Nm; post, 93.5±42.5Nm) torques did not show a significant changes during the exercise period. However, trunk rotation-flexion torque (pre, 52.9±26.5Nm; post, 82.4±65.8Nm) increased significantly (35.8%) after the exercise period (P<.05). The corresponding maximal electromyographic amplitudes of back and abdominal muscles remained unchanged. Disability, as assessed by visual analog scale and Oswestry Disability Index, did not change.

Conclusions

The CLBP patients performed therapeutic exercises with similar abdominal and back extensor muscle activities in the same way as the healthy subjects in our earlier studies. In this study, active physical rehabilitation had no effect on the abdominal and back muscle activities or on pain and functional disability indices.     

Evaluation of postural control in quiet standing using center of mass acceleration: comparison among the young, the elderly, and people with stroke

Yu E, Abe M, Masani K, Kawashima N, Eto F, Haga N, Nakazawa K. Evaluation of postural control in quiet standing using center of mass acceleration: comparison among the young, the elderly, and people with stroke.

Objective

To determine center of mass (COM) acceleration usefulness in the evaluation of postural control during quiet standing.

Design

Three-group comparison design.

Setting

A research laboratory.

Participants

Poststroke subjects (n=12), healthy elderly subjects (n=22), and healthy young subjects (n=25).

Interventions

Not applicable.

Main Outcome Measures

With a force platform, postural sway was evaluated by using the standard deviations of COM acceleration and center of pressure (COP) and COM (COP-COM) in which COP-COM represents the distance between the COP and the COM.

Results

COM acceleration and COP-COM variables were greater in the poststroke group than in the healthy groups (elderly and young) in the mediolateral (ML) direction. Both variables in the anteroposterior (AP) direction were greater in the poststroke group and the elderly group than in the young group. Furthermore, the correlations between COM acceleration and COP-COM in each group in each direction were shown to be significantly high (r range, .906-.979; P<.001).

Conclusions

COM acceleration was useful in the evaluation of postural control during quiet standing when comparing the young, the elderly, and poststroke patients. Additionally, COM acceleration and COP-COM in both the AP and ML directions during quiet standing were significantly and highly correlated. Thus, we proposed that COM acceleration can be an alternative and convenient measure instead of COP-COM in the evaluation of postural control.     

Issues and challenges for development of a sustainable service model for people with spinal cord injury living in rural regions

Middleton JW, McCormick M, Engel S, Rutkowski SB, Cameron ID, Harradine P, Johnson JL, Andrews D. Issues and challenges for development of a sustainable service model for people with spinal cord injury living in rural regions.

Objective

To develop and implement a service model for people with spinal cord injury (SCI) living in rural regions.

Design

Service development, pilot evaluation study.

Setting

Regional and remote areas of the state of New South Wales, Australia.

Participants

Persons with SCI, caregivers, and health professionals.

Intervention

Phase 1 included initial needs analysis, followed by education and resource development tailored to needs of rural health professionals, caregivers, and persons with SCI. Phase 2 included coordination, professional support, and network development by part-time rural key worker and metropolitan-based project officer, documenting health- and service-related issues.

Main Outcome Measures

Self-perception of confidence as a result of education as well as reported issues, adverse health events, and barriers to service provision.

Results

Clinician confidence in managing people with SCI improved after education. Various health-related, environmental, and psychosocial issues were reported. Limited availability of resources and health infrastructure, particularly in more isolated or smaller towns, challenged service provision. Rural key workers played a central role in supporting local clinicians and service providers, improving communication and service coordination between rural health professionals and metropolitan SCI services.

Conclusion

Education and support for rural workforce that may be limited in numbers and capacity, and a model facilitating communication and coordination between services, are essential for improving health outcomes of rural people with SCI.
