Effects of Meaningful Action Observation Therapy on Occupational Performance, Upper Limb Function, and Corticospinal Excitability Poststroke: A Double-Blind Randomized Control Trial.

Introduction: Action observation therapy (AOT) is a mirror neuron-based approach that has been recently used in poststroke rehabilitation. The main goal of this study was to investigate the effectiveness of AOT of occupations and tasks that are meaningful for chronic stroke patients on occupational performance, upper-extremity function, and corticospinal changes. Method: A randomized control trial was designed to compare between experimental (n = 13) and control groups (n = 14). In both groups, the execution of meaningful tasks was practiced, but the videos of those tasks were just shown to the experiment group. Instead, patients in the control group watched nature videos as a placebo. Clinical outcomes were evaluated using the Canadian Occupational Performance Measure (COPM), Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), and Box-Block Test (BBT) on 3 occasions: baseline, post (at 4 weeks), and follow-up (at 8 weeks). The assessments of central motor conduction time (CMCT) for abductor policis brevis (APB) and extensor indicis (EI) were only recorded at baseline and posttreatment. Both assessors of clinical and neurophysiological outcomes were blinded to the allocation of subjects. Result: Finally, the results of outcomes in 24 patients who completed the study were analyzed. In both groups, significant improvements after treatment were seen for most outcomes (p ≤ 0.05). These changes were persistent until follow-up. There were significant differences in COPM performance (p = 0.03) and satisfaction (p = 0.001) between the experimental and control groups. In contrast, other clinical assessments such as FMA, ARAT, and BBT did not show significant differences between the two treatments (p ≥ 0.05). The results of CMCT related to APB showed a more significant change in the experiment group compared to the control group (p = 0.022). There was no difference in change detected between the two groups for CMCT related to EI after treatments. Conclusion: Observation and execution of meaningful activities can enhance the effects of simply practicing those activities on occupational performance/satisfaction and corticospinal excitability poststroke.

The Effect of ICF-Core Set-Based Occupational Therapy Interventions on the Function and Satisfaction of Individuals with Chronic Stroke: A Randomized Clinical Trial.

Stroke can affect all aspects of a person's health and functioning. Therefore, it is important occupational therapists, have a comprehensive understanding of various levels of function and the factors affecting function. The ICF (International Classification of Functioning, Disability, and Health) and the selections of ICF categories or Core Sets relevant for people with a specific health condition, offer a model for intervention. This study aimed to investigate the effect of ICF-CS-based occupational therapy interventions on the function and satisfaction of individuals with chronic stroke. This study was designed as a randomized, single-blind, parallel-group clinical trial. Twenty-five patients with stroke were randomly assigned to the control group (which received traditional occupational therapy) or the treatment group (Stroke ICF-CS based occupational therapy). Patients were evaluated before and after the intervention (two months, three sessions per week, 45 minutes each session), as well as two weeks after the end of the intervention, using Fugl-Meyer and COPM (Canadian Occupational Performance Measure) tools. The independent T-test, Chi-square, and ANOVA with repeated measures were used to analyze the data. The results showed that the interaction effect of time and group was not significant in none of the Fugl-Meyer test sections (p > 0. 05), but it was significant in the performance and satisfaction of COPM (p < 0.05). The results suggest that ICF-CS-based occupational therapy interventions may assist persons with chronic stroke improve their functional level and satisfaction.

Predictors of mental health among parents of children with cerebral palsy during the COVID-19 pandemic in Iran: A web-based cross-sectional study.

BACKGROUND: Caring for children with cerebral palsy (CP) for many aspects of their lives may affect caregiver's psychological health. Emergence of COVID-19 put added pressure on caregivers. AIMS: The aim of this study was to investigate the psychological health of Iranian caregivers of children with CP and associated risks during a lockdown period. METHODS: Using online snowball sampling, 160 caregivers of children with CP participated in this web-based cross-sectional study. The Hospital Anxiety and Depression Scale (HADS), Perceived Stress Scale (PSS-4), Caregiver Difficulties Scale (CDS), and a demographic questionnaire were administered. Hierarchical multiple linear regression analysis was applied to identify risk factors related to caregiver psychological health. OUTCOMES AND RESULTS: Mental health problems were prevalent; (depression = 45.0% and anxiety = 40.6%). Significant correlations were found between CDS and HADS-Anxiety (r = 0.472, P < 0.001), HADS-depression (r = 0.513, P < 0.001), and perceived stress (PSS) related to COVID-19 (r = 0.425, P < 0.001). After controlling for demographic and clinical variables, burden (CDS) was found to significantly predict caregiver anxiety, depression and stress. Furthermore, several demographic characteristics (being married, low educational level and low income) were significantly related to high HADS Anxiety scores. For depression, only having a physical problem was significantly related to HADS among demographic variables. No significant correlations were found between PSS-4 and demographic variables. CONCLUSIONS AND IMPLICATIONS: During COVID-19 outbreak, the mental health of caregivers of children with CP is affected by multiple factors such as burden of care and demographic characteristics. Due to the importance of well-being among caregivers of disabled children, a comprehensive plan including psychological consultation, remote education, or in-person handouts for the self-care or handling of the children and adequate distance support may enable better mental health for these caregivers.

Effectiveness of Self-Action Observation Therapy as a Novel Method on Paretic Upper Limb and Cortical Excitability Post-Stroke: A Single-Subject Study.

Background: Action Observation Therapy (AOT) is a top-down approach that has been recently introduced in the rehabilitation of neurological disorders mainly after stroke. The main goal of this study was to investigate the effects and feasibility of a new technique in AOT procedure (called self-AOT) following periods of no treatment and routine AOT intervention on upper limb motor function, occupational performance and neurophysiological changes in a stroke patient. Methods: A single-subject A-B-A-C design was used and a 58-year-old woman with a 3-year history of left hemiplegia poststroke participated in this study. In the baseline (A1, A2) phases, the patient received no treatment. In the first intervention (B phase), she received a 4-week AOT, and in the second intervention (C phase), a 4 week of Self-AOT was practiced. In all phases, upper limb motor recovery as a target outcome was evaluated on 4 occasions using the Fugl-Meyer assessment. Upper limb function, dexterity and spasticity were assessed using Action Research Arm Test, Box-Block Test and Modified Modified Ashworth Scale respectively. Occupational Performance/Satisfaction was assessed with Canadian Occupational Performance Measure and to assess neuroplasticity, Motor Evoked Potential was recorded by Transcranial Magnetic Stimulation. Visual analysis, slope, and percentage of non-overlapping data were used for assessing the changes between phases. Results: Percentage of non-overlapping data and slopes indicated that motor recovery had clinically relevant improvements after both interventions compared to baselines. Other outcomes also showed improvements except for spasticity of wrist/elbow flexors and Motor Evoked Potential of opponens indicis. Conclusion: Self-AOT may be as effective as other procedures of AOT for improving upper limb motor function, occupational performance/satisfaction, and cortical excitability post-stroke.

Effect of Early Physical Activity Programs on Motor Performance and Neuromuscular Development in Infants Born Preterm: A Randomized Clinical Trial.

Introduction: Although the survival rate of infants born preterm has increased, the prevalence of developmental problems and motor disorders among this population of infants remains the same. This study investigated the effect of physical activity programs in and out of water on motor performance and neuromuscular development of infants born preterm and had induced immobility by mechanical ventilation. Methods: This study was carried out in Al-Zahra hospital, Tabriz. 76 premature infants were randomly assigned into four groups. One group received daily passive range of motion to all extremities based on the Moyer-Mileur protocol. Hydrotherapy group received exercises for shoulders and pelvic area in water every other day. A combination group received physical activity programs in and out of water on alternating days. Infants in a containment group were held in a fetal position. Duration of study was two weeks 'from 32 through 33 weeks post menstrual age (PMA). Motor outcomes were measured by the Test of Infant Motor Performance. Neuromuscular developmental was assessed by New Ballard scale and leg recoil and Ankle dorsiflexion items from Dubowitz scale. Data were analyzed using SPSS version 13. Results: TIMP and neuromuscular scores improved in all groups. Motor performance did not differ between groups at 34 weeks PMA. Postural tone of leg recoil was significantly higher in physical activity groups post intervention. Conclusion: Physical activities and containment didn't have different effects on motor performance in infants born preterm. Leg recoil of neuromuscular development items was affected by physical activity programs.

Combined effect of botulinum toxin and splinting on motor components and function of people suffering a stroke.

BACKGROUND: Spasticity is one of the problems after a stroke. Due to this increase in muscle tone, patients are confronted with problems in motor control and difficulties in activities of daily living and complications such as shortness and contracture. The aim of this study was to examine the effects of the simultaneous use of both splint and botulinum toxin-A (BTX-A) injection on spasticity, range of motion and upper extremity function in a 3-month period. METHODS: In this study a comparison was done between three groups of interventions, conducted in rehabilitation clinics in Tehran. Sixty people with chronic stroke were recruited. Based on the inclusion criteria, a total of 39 stroke patients after completing the consent forms were entered to intervention groups; splint or botulinum toxin injection or combined splint/botulinum toxin injection. They were followed up about three months and the evaluations were done monthly. Goniometry was the method to measure the range of motion, and Modified Ashworth Scale was used to examine the spasticity and the upper extremity function was scored based on Fugl- Meyer Assessment. Statistical analysis was done using SPSS 17. And ANOVAs was used for comparison between groups and times. Significance was set at 0.05. RESULTS: All outcome measures were improved within each group but the differences between splint group and BTX-A group and the BTX-A-splint group was not significant in most outcomes during the 3 periods (first evaluation until end of the first month, the end of first month until the end of second month, the end of second month until the end of the third month) (p>0.05). The results also showed that the changes in elbow`s spasticity (p=0.05) and wrist`s spasticity (p=0.007) and upper extremity function (p=0.04) were obvious between the three groups over the 3-months and the difference in the group of combined use of botulinum toxin, and the splint was more than other groups. CONCLUSION: In this study, the effects of botulinum toxin injection and Volar-Dorsal Wrist/Hand Immobilization splint and the combined use of botulinum injection and splint were obvious in all groups but was not significantly different between the interventions in a 3-month follow-up.

Cross-cultural validation of the Persian version of the Functional Independence Measure for patients with stroke.

PURPOSE: To translate and cross-culturally adapt the Functional Independence Measure (FIM) into the Persian language and to test the reliability and validity of the Persian FIM (PFIM) in patients with stroke. METHOD: In this cross-sectional study carried out in an outpatient stroke rehabilitation center, 40 patients with stroke (mean age 60 years) were participated. A standard forward-backward translation method and expert panel validation was followed to develop the PFIM. Two experienced occupational therapists (OTs) assessed the patients independently in all items of the PFIM in a single session for inter-rater reliability. One of the OTs reassessed the patients after 1 week for intra-rater reliability. RESULTS: There were no floor or ceiling effects for the PFIM. Excellent inter-rater and intra-rater reliability was noted for the PFIM total score, motor and cognitive subscales (ICC(agreement)0.88-0.98). According to the Bland-Altman agreement analysis, there was no systematic bias between raters and within raters. The internal consistency of the PFIM was with Cronbach's alpha from 0.70 to 0.96. The principal component analysis with varimax rotation indicated a three-factor structure: (1) self-care and mobility; (2) sphincter control and (3) cognitive that jointly accounted for 74.8% of the total variance. Construct validity was supported by a significant Pearson correlation between the PFIM and the Persian Barthel Index (r = 0.95; p < 0.001). CONCLUSIONS: The PFIM is a highly reliable and valid instrument for measuring functional status of Persian patients with stroke. IMPLICATIONS FOR REHABILITATION: The Functional Independence Measure (FIM) is an outcome measure for disability based on the International Classification of Functioning, Disability and Health (ICF). The FIM was cross-culturally adapted and validated into Persian language. The Persian version of the FIM (PFIM) is reliable and valid for assessing functional status of patients with stroke. The PFIM can be used in Persian speaking countries to assess the limitations in activities of daily living of patients with stroke.

Low frequency repetitive transcranial magnetic stimulation to improve motor function and grip force of upper limbs of patients with hemiplegia.

BACKGROUND: Stroke is the most common and debilitating neurological disorder among adults, and is a sudden onset of neurological signs caused by brain blood vessels impairments. OBJECTIVES: Some new therapeutic methods focus on the use of magnetic stimulation to produce therapeutic effects by inducing the currents. The aim of this study is to determine the effects of rTMS plus routine rehabilitation on hand grip and wrist motor functions in patients with hemiplegia, and compare with pure routine rehabilitation programs. PATIENTS AND METHODS: In this study, 12 patients with hemiplegia were randomly divided in two groups. Control group, received the rehabilitation program with placebo magnetic stimulation, and the experimental group, received magnetic stimulation with routine rehabilitation program for 10 sessions for three times per week. Pre and post evaluations of treatment performed using Barthel and Fugl-Meyer indices and dynamometers. RESULTS: In the control group, Barthel and Fugl-Meyer indices showed significant improvement (P = 0.01, P = 0.00), while in the experimental group, significant improvement in Barthel and Fugl-Meyer indices and dynamometers has been observed (P = 0.01, P = 0.00, P = 0.007). CONCLUSIONS: rTMS can improve hand muscle force and functions of patients with chronic hemiplegia, while conventional treatment is not effective.
