The effectiveness of occupational therapy in restoring the functional state of hands in rheumatoid arthritis patients.
(65/332)
The aim of the study was to evaluate the effectiveness of occupational therapy in rheumatoid arthritis patients with impaired hand function. Standardized Functional Independence Measure was employed in order to evaluate the functional status of the patients and impaired activities. A dynamometer was used for the measurements of muscular strength of hands and a goniometer, for the range of motion of the wrist. Totally, we have examined 120 rheumatoid arthritis patients. They were divided into two groups: 60 patients in each. Occupational therapy was applied only to the patients of the first group. The mean age of Group 1 patients was 53.4+/-1.8 years, the mean age of Group 2 patients was 52.0+/-1.9 years. The mean duration of the disease was 11.5+/-2.6 years and 12.1+/-2.4 years, respectively. The effectiveness of therapy was considered ineffective if, after the completion of the course of occupational therapy, no increase in Functional Independence Measure score for patients with rheumatoid arthritis was observed. When the score increased from 1 to 3, we considered this as moderate effectiveness; when the score increased to 4-6, we evaluated the effectiveness of occupational therapy as good, and when the score of 7 was attained, effectiveness of occupational therapy was considered as very good. In Group 1, the moderate effectiveness of occupational therapy was determined in 31.7% of patients; good effectiveness, in 61.7%; and very good effectiveness, in 3.3% of rheumatoid arthritis patients. In Group 2, the moderate effectiveness of treatment was determined in 48.3% of patients and good effectiveness, in 5% of rheumatoid arthritis patients. CONCLUSIONS. Hand function (the strength of fingers and hands, the range of motion of the wrist) significantly improved in patients with rheumatoid arthritis after completion of a course of occupational therapy (p<0.05). The improvement of hand functions in patients with rheumatoid arthritis led to increased ability to take food and drink, to wash themselves, to put the clothes on the upper and lower parts of the body and take them off, to use the toilet, a bathtub or a shower, to walk, to manage a wheelchair, and to do personal hygiene (p<0.05).

Community based occupational therapy for patients with dementia and their care givers: randomised controlled trial.
(66/332)
OBJECTIVE: To determine the effectiveness of community based occupational therapy on daily functioning of patients with dementia and the sense of competence of their care givers. DESIGN: Single blind randomised controlled trial. Assessors were blinded for treatment allocation. SETTING: Memory clinic and day clinic of a geriatrics department and participants' homes. PARTICIPANTS: 135 patients aged > or =65 with mild to moderate dementia living in the community and their primary care givers. INTERVENTIONS: 10 sessions of occupational therapy over five weeks, including cognitive and behavioural interventions, to train patients in the use of aids to compensate for cognitive decline and care givers in coping behaviours and supervision. MAIN OUTCOME MEASURES: Patients' daily functioning assessed with the assessment of motor and process skills (AMPS) and the performance scale of the interview of deterioration in daily activities in dementia (IDDD). Care giver burden assessed with the sense of competence questionnaire (SCQ). Participants were evaluated at baseline, six weeks, and three months. RESULTS: Scores improved significantly relative to baseline in patients and care givers in the intervention group compared with the controls (differences were 1.5 (95% confidence interval 1.3 to 1.7) for the process scale; -11.7 (-13.6 to -9.7) for the performance scale; and (11.0; 9.2 to 12.8) for the competence scale). This improvement was still significant at three months. The number needed to treat to reach a clinically relevant improvement in motor and process skills score was 1.3 (1.2 to 1.4) at six weeks. Effect sizes were 2.5, 2.3, and 1.2, respectively, at six weeks and 2.7, 2.4, and 0.8, respectively, at 12 weeks. CONCLUSIONS: Occupational therapy improved patients' daily functioning and reduced the burden on the care giver, despite the patients' limited learning ability. Effects were still present at 12 weeks, which justifies implementation of this intervention. TRIAL REGISTRATION: Clinical Trials NCT00295152 [ClinicalTrials.gov]. (+info)
Reliability of the ICF Core Set for rheumatoid arthritis.
(67/332)
BACKGROUND: The comprehensive ICF Core Set for rheumatoid arthritis (RA) is a selection of 96 categories from the International Classification of Functioning, Disability and Health (ICF), representing relevant aspects in the functioning of RA patients. OBJECTIVES: To study the reliability of the ICF Core Set for RA in rheumatological practice, and to explore the metric of the qualifiers' scale. METHODS: 25 RA patients from an outpatient department of rheumatology were interviewed using the ICF Core Set for RA (76% females, mean (SD) age 57.5 (12.5) years, disease duration 15.9 (14.6) years). Interviews were performed independently by both a physiotherapist and an occupational therapist on the same day and again after one week by one of them. The severity of the patients' problems was quantified on a qualifier scale ranging from 0 (no problem) to 4 (complete problem). Analyses of intra-rater and inter-rater agreement, kappa statistics, and Rasch analyses were applied. RESULTS: Mean intra-rater (inter-rater) complete agreement for all categories was seen in 59% (47%) of observations, ranging from 29% (0%) to 96% (80%) for individual categories. Weighted kappa statistics with value > or =0.4 showed reliability in 86% of categories within raters, and in 43% of categories between raters. Improved inter-rater and intra-rater reliability was observed with a reduced number of qualifiers for the categories. CONCLUSIONS: Inter-rater and intra-rater reliability of the ICF Core Set of RA was low to moderate. The metric of the qualifiers' scale may be improved by reducing the number of qualifiers to three for all components. (+info)
Little therapy, little physical activity: rehabilitation within the first 14 days of organized stroke unit care.
(68/332)
OBJECTIVE: To examine rehabilitation interventions and resulting physical activity patterns of patients managed in acute stroke units to help inform development of a randomized controlled trial of very early rehabilitation. DESIGN: An open observational study of patient activity and therapist report of patient interventions. A survey of stroke unit resources. METHODS: Patients less than 14 days post-stroke from 5 metropolitan stroke units were observed over 2 consecutive weekdays at 10-minute intervals between 08.00 h and 17.00 h. Physical activity, location and person(s) present were ascertained at each observation. Therapists completed treatment records. Senior staff completed stroke unit surveys. RESULTS: Patients after stroke (n=58) were with therapists 5.2% of the observed day. Few patients (17.1%) received daily therapy by more than one therapist. When patients received therapy, average session times were 24 minutes of physiotherapy, 23 minutes of occupational therapy and 33 minutes of speech pathology. The more time that family members were present, the longer the treatment time. Four to 11 min of upper-limb therapy was provided. Muscle weakness and left hemiparesis were associated with less upper-limb activity. CONCLUSION: These acute stroke care units were resourced according to recommended staff-patient ratios. Patients received little therapy and had low levels of physical activity. (+info)
The efficacy of interactive lecturing for students with diverse science backgrounds.
(69/332)
Learning is an active process, and, as such, interactive lectures are considered as the educational best practice. This study investigated the efficacy of interactive lecturing in a module of eight respiratory physiology lectures in a second-year Physiology course with two distinct subcohorts: students with strong science backgrounds and those without. The comparison of student performance in the summative examinations of respiratory physiology allowed us to evaluate the efficacy of interactive lecturing for each subcohort. Formal teaching evaluations were used to gauge the students' perception of interactive lectures. To further validate our findings, we repeated the study in the following year. The introduction of interactive lecturing significantly improved learning outcomes, with this improvement being maintained for the period of this study. Furthermore, students with limited prior knowledge, who had typically performed very poorly in this module, achieved a similar learning outcome to those students with a good science background. From these summative results and the students' perceptions, we concluded that students that are alert, motivated and interested in the subject, and engaged in learning activities and that are being encouraged to think and receive constant feedback on their progress will become confident in their learning abilities and have improved learning outcomes.

Development and validation of a German version of the joint protection behavior assessment in patients with rheumatoid arthritis.
(70/332)
OBJECTIVE: Joint protection (JP) is an important part of the treatment concept for patients with rheumatoid arthritis (RA). The Joint Protection Behavior Assessment short form (JPBA-S) assesses the use of hand JP methods by patients with RA while preparing a hot drink. The purpose of this study was to develop a German version of the JPBA-S (D-JPBA-S) and to test its validity and reliability. METHODS: A manual was developed through consensus with 8 occupational therapist (OT) experts as the reference for assessing patients' JP behavior. Twenty-four patients with RA and 10 healthy individuals were videotaped while performing 10 tasks reflecting the activity of preparing instant coffee. Recordings were repeated after 3 months for test-retest analysis. One rater assessed all available patient recordings (n = 23, recorded twice) for test-retest reliability. The video recordings of 10 randomly selected patients and all healthy individuals were independently assessed for interrater reliability by 6 OTs who were explicitly asked to follow the manual. Rasch analysis was performed to test construct validity and transform ordinal raw data into interval data for reliability calculations. RESULTS: Nine of the 10 tasks fit the Rasch model. The D-JPBA-S, consisting of 9 valid tasks, had an intraclass correlation coefficient of 0.77 for interrater reliability and 0.71 for test-retest reliability. CONCLUSION: The D-JPBA-S provides a valid and reliable instrument for assessing JP behavior of patients with RA and can be used in German-speaking countries. (+info)
Feasibility and results of a randomised pilot-study of pre-discharge occupational therapy home visits.
(71/332)
BACKGROUND: Pre-discharge home visits aim to maximise independence in the community. These visits involve assessment of a person in their own home prior to discharge from hospital, typically by an occupational therapist. The therapist may provide equipment, adapt the home environment and/or provide education. The aims of this study were to investigate the feasibility of a randomised controlled trial in a clinical setting and the effect of pre-discharge home visits on functional performance in older people undergoing rehabilitation. METHODS: Ten patients participating in an inpatient rehabilitation program were randomly assigned to receive either a pre-discharge home visit (intervention), or standard practice in-hospital assessment and education (control), both conducted by an occupational therapist. The pre-discharge home visit involved assessment of the older person's function and environment, and education, and took an average of 1.5 hours. The hospital-based interview took an average of 40 minutes. Outcome data were collected by a blinded assessor at 0, 2, 4, 8 and 12 weeks. Outcomes included performance of activities of daily living, reintegration to community living, quality of life, readmission and fall rates. RESULTS: Recruitment of 10 participants was slow and took three months. Observed performance of functional abilities did not differ between groups due to the small sample size. Difference in activities of daily living participation, as recorded by the Nottingham Extended Activities of Daily Living scale, was statistically significant but wide confidence intervals and low statistical power limit interpretation of results. CONCLUSION: Evaluation of pre-discharge home visits by occupational therapists in a rehabilitation setting is feasible, but a more effective recruitment strategy for a main study is favored by application of a multi-centre setting.

Reliability of near-infrared spectroscopy measures of cerebral oxygenation and blood volume during handgrip exercise in nondisabled and traumatic brain-injured subjects.
(72/332)
We compared the test-retest reliability of near-infrared spectroscopy (NIRS) measures of cerebral oxygenation and blood volume during a rhythmic handgrip exercise in 13 nondisabled subjects and 25 subjects with moderate to severe traumatic brain injury (TBI). Subjects with TBI (average Glasgow Coma Scale score = 4.2, average time since injury = 21 mo) had completed an acute brain injury rehabilitation program. After 2 min of rest, each subject performed 60 s of maximal rhythmic handgrip contractions with the right hand in two trials 24 to 48 h apart. We used NIRS to measure cerebral oxygenation and blood volume responses from the left prefrontal lobe. Both groups' cerebral oxygenation and blood volume increased during handgrip contractions. The change in cerebral oxygenation was significantly lower in subjects with TBI compared with nondisabled subjects. Intraclass correlations between the two trials for cerebral oxygenation and blood volume were 0.83 and 0.80, respectively, in nondisabled subjects and 0.70 and 0.64, respectively, in subjects with TBI. The findings indicate that NIRS is a reliable noninvasive technique for evaluating cerebral oxygenation and blood volume changes during motor function. NIRS can be useful in monitoring recovery of cerebral oxygenation during rehabilitation of patients with TBI. (+info)
