Long-term outcome of equestrian injuries in children

Purpose: To investigate the possible development of long-term disabilities arising from paediatric equestrian injuries.

Method: All patients, aged 17 years or younger, treated in a hospital setting because of an equestrian injury during a five-year period received a questionnaire. A reference population and healthy friends served as controls.

Results: Four years post-injury, 41 of the 100 respondents still experienced disabilities following the injury. The median Injury Severity Score was 4. Absenteeism from school lasted 2 weeks, and from horse riding, 4 months. Compared to the reference population, the results of the Child Health Questionnaire were poorer considering most of its subscales. In comparison with the friends, the patients only scored lower on 'physical functioning'. The risk factors concerning poor long-term outcomes were being an advanced rider, sustaining injuries other than fractures of the extremities or sustaining subsequent injuries following the riding accident.

Conclusions: Although equestrian injuries in children are minor to moderate in their severity, these injuries are significant considering that a large proportion of patients experience long-term disabilities.     

Role of disengagement failure and attentional gradient in unilateral spatial neglect - a longitudinal study

Purpose: To assess the importance of 'disengagement failure' and 'attentional gradient' in unilateral spatial neglect (USN) and in recovery from neglect.

Method: Eight right-hemisphere-damaged stroke patients performed the standardized Behavioural-Inattention-Test battery for visual neglect, line-bisection tests, and two computerized reaction-time (RT) tasks: a variant of Posner's 'Spatial-Cueing' paradigm (with special emphasis on the magnitude of leftward disengagement time) and a signal-detection task (marking the spatial gradient of attention by the distribution of RTs to target stimuli in different spatial locations). The correlation between the different measures was assessed at two points in time, before and after a period of rehabilitation treatment.

Results: A recovery pattern could be identified in both RT paradigms. However, the correlation between standard measures of neglect and performance on both, spatial-cueing and signal-detection tasks, was weak.

Conclusion: Neither difficulty disengaging attention from an ipsilesional stimulus nor changes in the attentional gradient can fully explain the processes underlying USN and its recovery. A large interpersonal variance exists among USN patients in the expression of disengagement and other spatial-attention deficits. Hence, individual patients should be tested by measuring different factors known to play a role in USN. This information is crucial for assigning the appropriate treatment for each patient in accord with the specific deficit revealed.     

Is social participation associated with quality of life of older adults with physical disabilities?

Purpose: To explore the relationships between subjective quality of life and social participation of older adults with physical disabilities.

Method: A cross-sectional design was used with a convenience sample of 46 people aged 60 to 90 living in the community. Subjective quality of life was estimated with the Quality of Life Index and social participation with the Assessment of Life Habits.

Results: Only a weak relationship was found between total scores of quality of life and social participation. Interpersonal relationships, responsibilities, fitness and recreation were the categories of social participation most associated with quality of life. Social roles were more associated with quality of life than daily activities. Finally, satisfaction with the accomplishment of life habits was also more associated with quality of life than the performance itself.

Conclusions: The importance of social participation in regard to the quality of life of older persons with physical disabilities living in the community is partially supported by these findings. Other studies are needed to clarify how social participation influences quality of life in this population.     

Functional outcome in patients with critical illness polyneuropathy

Purpose: To evaluate the functional outcome of intensive care patients with critical illness polyneuropathy (CIP), 6 and 12 months after the onset.

Methods: Design: A prospective observational cohort study and a cross-sectional study.

Setting: University hospital in the Netherlands.

Patients: Eight consecutive intensive care patients with CIP for the prospective study and eight patients diagnosed with CIP in the past 6 months for the cross-sectional study.

Main outcome measures: Functional outcome regarding body functions and structure, activities, participation and perceived quality of life.

Results: Nine patients (56%) died within one year. Functional outcome, participation and subjective health status in survivors varied widely at 6 and 12 months. After 12 months, physical functioning was improved in all patients. However activities related to mobility outdoors, autonomy, participation and quality of life were restricted in most patients.

Conclusions: The majority of survivors have persistent functional disabilities in activities, reduced quality of life and restrictions in autonomy and participation one year after the onset of CIP. Prolonged rehabilitation treatment is necessary for an increasing number of intensive care patients who develop CIP, in order to reduce handicaps and achieve optimal autonomy and social participation.     

Measuring fatigue in people with multiple sclerosis

Objective: To compare methods of assessing fatigue.

Design: Cross sectional.

Setting: Community.

Subjects: Forty Multile Sclerosis (MS) patients and 20 healthy controls.

Main outcome measures: Fatigue questionnaires, SDSA dot cancellation test, finger tapping test, TEA Lottery.

Results: The MS patients had significantly higher levels of fatigue than the controls on the Task Induced Fatigue Scale, Fatigue Severity Scale and Fatigue Impact Scale. The Task Induced Fatigue Scale completed whilst imagining oneself driving and the Fatigue Assessment Instrument did not differentiate between MS patients and controls. Finger tapping differentiated between MS patients and controls but there was no significant difference between MS patients and controls on visual and auditory concentration tests. A factor analysis indicated that questionnaire measures of fatigue were inter-related but independent of objective test performance.

Conclusions: Questionnaire measures can be used to assess fatigue in people with MS. The FSS differentiated MS patients from controls and is relatively short. It was therefore recommended for clinical use.     

The efficiency of electromagnetic field treatment in Complex Regional Pain Syndrome Type I

Introduction: Complex Regional Pain Syndrome Type I is a pathological condition that occurs without evident nerve injury and follows a course characterized by severe pain.

Purpose: The aim of this study is to assess whether or not electromagnetic field treatment administered with calcitonin and exercise has positive effects on clinical improvement, scintigraphic assessment and bone markers compared to calcitonin and exercise administration.

Method: In this randomized double-blind, placebo-controlled study, 40 patients with Complex Regional Pain Syndrome Type I, that developed after a Colles fracture were included in the assessments and were administered calcitonin and exercise treatment for 6 weeks. In addition to this treatment, half the patients received electromagnetic field treatment, and the other half received placebo treatment. The patients were evaluated at the beginning and end of treatment with clinical parameters, scintigraphic assessment and biochemical markers.

Results: Although we found some significant improvements in our evaluation criteria, we could not find a significant statistical difference between groups.

Conclusions: The absence of a significant difference between the two groups in the assessment parameters has been interpreted as evidence that electromagnetic field treatment does not provide additional benefit to calcitonin and exercise treatment.     

Microswitch clusters to support responding and appropriate posture of students with multiple disabilities: three case evaluations

Purpose: This study extended the evaluation of microswitch clusters to support responding and appropriate posture with three students with multiple disabilities.

Method: Initially, a baseline level was established for the target response selected for each student. Then, Intervention I was implemented to increase the frequency of that response through the presentation of favourite stimuli. During Intervention II, the response was followed by favourite stimuli only if the microswitch cluster detected it in combination with appropriate posture. Post-intervention checks were carried out within 2 or 3 months from the end of Intervention II.

Results and conclusions: All students showed an increase in the frequency of the target response during Intervention I and in the percentage of times the response occurred in combination with appropriate posture during Intervention II. These changes lasted over time. The importance of microswitch clusters to enhance the performance of students with multiple disabilities was underlined.     

A comparison of consumer-directed and agency-directed personal assistance services programmes

Purpose: To compare a consumer-directed personal assistance services (PAS) programme with an agency-directed PAS programme.

Method: A convenience sample was used for this cross-sectional study with one data collection point. Outcomes were compared for consumer-directed and agency-directed PAS. Hierarchical regressions were also used to determine the predictors of outcomes across PAS programmes. In-home interviews were conducted by a trained data collector from April 2000 to December 2001.

Results: Participants in the consumer-directed programme reported more choices over PAS and satisfaction with PAS. Self-reported outcomes were primarily predicted by the following variables: service arrangement, type of provider, importance of directing PAS, health status, number of personal assistants used in past 12 months, sufficient PAS hours received, and social support.

Conclusions: Consumer-directed PAS enhances outcomes for many persons with disabilities. Self-reported outcomes are affected by many factors that could be addressed in PAS programme development.     

Barriers to accessing safe motherhood and reproductive health services: the situation of women with disabilities in Lusaka, Zambia

Purpose: To ascertain how well health services in Lusaka, Zambia currently meet the safe motherhood and reproductive health care needs of women who have physical impairment leading to disability.

Methods: A qualitative study was conducted in Lusaka, Zambia. In-depth tape-recorded interviews were conducted with 24 purposively selected women with disabilities and with 25 safe motherhood/reproductive public sector health service providers. Qualitative analysis was conducted using NVivo software.

Results: Women with disabilities encounter various social, attitudinal and physical barriers to accessing safe motherhood and reproductive health (RH) services in this particular setting. The strong desire for children and affection can increase vulnerability to sexual exploitation. At the same time, a generalized assumption among reproductive health service providers that women with disabilities will not be sexually active, and not require RH services, leads to increased vulnerability to sexually transmitted infection including HIV. Once pregnant, traditional beliefs about transmission of disabilities can create barriers to integration in ante-natal clinics. Nurse-midwives' fear of delivery complications in women with physical impairments can also result in routine over-referral to a tertiary maternity facility which is outside the locality and harder for women with mobility limitations to get to.

Conclusion: Greater understanding of the influences underpinning societal attitudes towards sexuality and disability in this setting, and more extensive communication between health care staff and women with disabilities would facilitate positive action towards improving safe motherhood and reproductive health services for women with disabilities.     

Strength and endurance training of an individual with left upper and lower limb amputations

Purpose: The purpose of this article is to describe the development of a strength and endurance training programme designed to prepare an individual with a left glenohumeral disarticulation and transtibial amputation for a bike trip across the USA.

Method: The subject was scheduled for training three times per week over a two-month period followed by two times per week for an additional two months. Training consisted of a resistance training circuit using variable resistance machines, cycling using a recumbent stationary bike, and core stability training using stability ball exercises. Changes in strength were assessed using 10 RM tests on the resistance machines and changes in peak VO₂ were monitored utilizing the Cosmed K4b²® pulmonary function tester.

Results: The subject demonstrated a 30.3% gain in peak VO₂. The subject's 10 RM for left single limb leg press increased 36.8% and gains of at least 7.7% were seen for all other muscle groups tested.

Conclusion: The strength and endurance training programme adapted to compensate for this subject's limb losses was effective in increasing both strength and peak VO₂. Adapting exercise programmes to compensate for limb loss may allow individuals with amputations to participate in physically challenging activities that otherwise may not be available to them.     

Impact of middle ear effusion on balance performance in children

Middle ear effusion (MEE) is a common childhood disease characterized by accumulation of fluid in the middle ear. MEE treatment focuses on the resultant conductive hearing loss. Recently, researchers have investigated the potential effects of MEE on balance.

Purpose: The purpose of this study was to compare balance of children with MEE to that of healthy children and to examine whether a relation exists between balance skills and the degree of muscle strength.

Methods: Twenty children with MEE and twenty healthy children aged 4.5 - 7.5 years underwent balance and strength sub-tests of Bruininks - Oseretsky Test of Motor Performance (BOTMP) and electronystagmography recordings (ENG). Parents completed a questionnaire designed to elicit their perceptions of their child's balance abilities in daily living activities.

Results: MEE children performed significantly worse than did the control group on BOTMP balance sub-test. BOTMP strength subtest indicated that children with MEE had poorer muscle strength than the control group, although the difference was not significant. ENG results showed no pathologic recordings in both study group and control group. Finally, a significant correlation was found between parents' responses on the questionnaire and their child's performance on BOTMP balance subtest.

Conclusions: MEE may negatively impact children's balance, while muscle strength is less affected. Furthermore, the BOTMP appears to be a sensitive assessment of balance disturbances in children with MEE.     

Performance of activities of daily living in multiple sclerosis

Purpose: To assess the performance of activities of daily living (ADL) in individuals with moderate to severe multiple sclerosis (MS).

Method: A total of 12 men and 32 women with MS (Expanded Disability Status Scale, EDSS, 6.0 - 8.5) were studied. The performance of personal ADL (P-ADL) and instrumental ADL (I-ADL) was assessed with the Functional Independence Measure (FIM) and the Assessment of Motor and Process Skills (AMPS).

Results: Twenty-four of the 44 individuals were rated dependent in P-ADL by the FIM motor score, mainly due to limitations in some areas of self-care and in transfers and locomotion. Only three individuals were rated dependent by the FIM cognitive score, indicating no or little cognitive disability. Two thirds of the individuals who were rated independent/modified independent in P-ADL by the FIM were rated dependent in I-ADL by the AMPS. Only the FIM motor score was significantly related to the EDSS score, indicating that ADL performance and disease severity is weakly related.

Conclusions: Moderate to severe MS reduces the ability to perform both P-ADL and I-ADL. An individual with MS can be independent in P-ADL but still unable to perform I-ADL satisfactorily. Assessments of both P-ADL and I-ADL are advocated to evaluate ADL performance in order to implement appropriate management strategies for individuals with MS.     

Client,needs assessor and agency-related factors predicting allocation of electric scooters to community-dwelling elderly in The Netherlands: a vignette study

Purpose: To determine what client factors predict allocation of an electric scooter and to determine what needs assessor and agency factors explain variation in decision-making by long-term care needs assessors concerning clients requesting electric scooters.

Method: Hypothetical case vignettes were sent to needs assessors allocating services for the elderly, and questionnaires were used to obtain organizational and individual needs assessor data. Multilevel logistic regression analysis provided random and fixed effects.

Results: The decision whether or not to allocate an electric scooter was influenced primarily by the clients' driving safety, their disabilities and whether or not there were possibilities to stall the electric scooter. Transportation goals and the clients' activity level were not taken into account. There was some random variation on the level of needs assessors.

Conclusions: A system whereby all clients who request an electric scooter, have disabilities that limit mobility, have shown to be safe drivers and have a shed to stall the scooter are allocated a scooter may be more appropriate in maintaining elderly persons' independence and preventing social isolation. Regular evaluation afterwards and extra driving lessons may prevent allocation of scooters to clients who do not use them.     

Key factors in the development of lower limb co-ordination: implications for the acquisition of walking in children with cerebral palsy

Purpose: This paper explores differences in walking development between normal children and those with cerebral palsy and discusses their clinical implications.

Method: A literature review (MEDLINE, RECAL) of walking development in normal children and those with cerebral palsy, including the use of walking aids.

Results: Normal neonates display reflexive stepping, at 8 months supported walking and then independent walking emerge at about 12 months. Transition from the wide-based, high stepping gait to narrower base, heel-toe gait with arm swing occurs within 6 months of walking. Gait is mature by 7 years. Children with cerebral palsy have delayed walking. Prognostic factors include retained reflexes, age of head control and of independent sitting. They retain kinematic and muscle activation patterns seen in supported walking. Older children show co-contraction patterns and lose range of motion at leg joints. Walking aids have been studied for energy consumption, but only independent walking patterns are described. Treadmills and partial weight relief have been used for walking training.

Conclusions: Children with cerebral palsy fail to achieve the transition from supported stepping to mature gait patterns. Assessment tools to identify gait maturity need to be developed so that treatment that promotes transitions can be promoted and effectively monitored.     

A comparison of the grip force distribution in natural hands and in prosthetic hands

Purpose: The aim of this study is to analyse the grip force distribution for different prosthetic hand designs and the human hand fulfilling a functional task.

Method: A cylindrical object is held with a power grasp and the contact forces are measured at 20 defined positions. The distributions of contact forces in standard electric prostheses, in a experimental prosthesis with an adaptive grasp, and in human hands as a reference are analysed and compared. Additionally, the joint torques are calculated and compared.

Results: Contact forces of up to 24.7 N are applied by the middle and distal phalanges of the index finger, middle finger, and thumb of standard prosthetic hands, whereas forces of up to 3.8 N are measured for human hands. The maximum contact forces measured in a prosthetic hand with an adaptive grasp are 4.7 N. The joint torques of human hands and the adaptive prosthesis are comparable.

Conclusions: The analysis of grip force distribution is proposed as an additional parameter to rate the performance of different prosthetic hand designs.     

Leisure-time physical activity and secondary conditions in women with physical disabilities

Purpose: To examine the relationship between secondary conditions and leisure-time physical activity participation (LTPA) in women with physical disabilities.

Method: A survey was conducted in a metropolitan urban USA area of women (n = 170) with physical disabilities including MS, CP, polio, arthritis, TBI, and CVA among others and aged 21 - 65 years. Outcome measures were LTPA, secondary conditions (numbers and severity), and functional status.

Results: Respondents experienced 11.99 ( ± 6.05) secondary conditions in the past year, self-rated their severity as 'moderate problems', and reported moderate levels of functional impairment. LTPA participation (excluding calisthenics/exercise) was reported to be 2.90 ( ± 5.12) times/week with 39.4% reporting no participation. After controlling for the interaction between severity of secondary conditions and functional status, the secondary conditions of physical deconditioning and isolation were significantly and inversely related to LTPA participation (r = - 0.164, p = 0.036; r = - 0.156, p = 0.045, respectively).

Conclusion: Reported secondary conditions of physical deconditioning and isolation are inversely related to the ability of moderately impaired women with physical disabilities to participate in LTPA when functional status was controlled and should be considered in efforts to increase involvement in this health promoting behaviour.     

Impairments, disabilities and health related quality of life after treatment for breast cancer: a follow-up study 2.7 years after surgery

Purpose: The aim of this study was to assess impairments, disabilities and health related Quality of Life (QOL) after treatment of breast cancer and to analyse the relationship between treatment modalities, impairments, disabilities and health related QOL.

Method: Fifty-five patients who underwent a modified radical mastectomy or a segmental mastectomy with axillary lymph node dissection were retrospectively assessed with a mean follow up of 2.7 years after treatment. Impairments were assessed by means of measuring active shoulder range of motion, grip strength, arm volume and pain. Disabilities were assessed by means of the Shoulder Disability Questionnaire (SDQ) and health related QOL was assessed by means of the RAND 36-item Health Survey (RAND-36).

Setting: University Hospital Groningen (The Netherlands).

Results: Pain (60%) and reduction of grip-strength (40%) were the most frequent impairments found. The prevalence of impaired range of motion and oedema was 9 - 16% respectively 15%. Mean group score of the SDQ was 33.7 (sd: 32.1) and mean scores of the RAND-36 differed significantly for physical functioning, vitality and health perception to that of a female norm group. Radiotherapy and chemotherapy were significant factors in the prediction of impaired range of motion. Pain and restricted range of motion explained 61% respectively 12% of the variance in disability (SDQ). In the prediction of health related QOL, pain, grip strength and arm volume were significant factors respectively in six, three and two domains.

Conclusions: Pain is the most frequent assessed impairment after breast cancer treatment with strong relationship to perceived disability and health related QOL. Disability is mild and health related QOL (RAND-36) differed in three of the nine domains with a female norm group.     

Functional evaluation of vascular hemiparetics and traditional Japanese houses

Purpose: To study the functional status of vascular hemiparetics in outpatient clinics in Japan.

Method: Following five functional tasks were evaluated to (1) pick up a pencil from the floor, (2) stand up from the floor, (3) sit up straight, (4) squat, (5) ambulate as far as possible. Patients were asked whether they added handrails and used a bed or a Japanese Futon.

Results: Sixty-three of 85 patients were able to pick up a pencil from the floor and to stand up from the floor. Patients with poor motor recovery of the lower extremities were able get into and out of a bathtub as well as patients with good motor recovery. All patients who could not ambulate for more than 100 m and could not stand up from the floor began to use beds after their strokes.

Conclusions: Ninety-five per cent of patients who could stand up from the floor were able to get into and out of bathtubs. All of the patients who could not stand up from the floor started to use beds.
