A Delphi Panel of People With Parkinson's Disease Regarding Responsibility: Toward a Preliminary Taxonomy

IMPORTANCE

A sense of agency is associated with complex occupation-related responsibilities. A taxonomy can guide clinicians in enhancing responsibility in patients with Parkinson's disease (PwPD).

OBJECTIVE

To (1) discover levels of responsibility in occupations for PwPD and (2) propose a taxonomy for occupations.

DESIGN

A two-round Delphi study with PwPD and a one-round Delphi study with international experts.

SETTING

Electronic survey.

PARTICIPANTS

PwPD (N = 75) and international experts (N = 8).

OUTCOMES AND MEASURES

PwPD expressed their levels of an inherent sense of responsibility for each occupation (1 = very low responsibility, 5 = very high responsibility). International experts rated their level of agreement (5 = strongly agree, 1 = strongly disagree) with each dimension of the taxonomy. A consensus was determined to have been reached if the interquartile range was ≤1 and 70% agreement in two adjacent categories was achieved.

RESULTS

Thirty-three occupation categories were deemed as having very high to moderate responsibility for PwPD. Consequences of actions and the presence of others made up the two-dimensional responsibility taxonomy. Occupations have more challenging responsibility characteristics when they are performed with free choice, a level of high physical effort, alone, and with moral consequences.

CONCLUSIONS AND RELEVANCE

This study yielded the first consensus among PwPD regarding responsibility in occupations as well as a classification system for charting the complexity of responsibility in occupations. The occupation list we have created can be beneficial to health care professionals when providing interventions or conducting outcome assessments. Plain-Language Summary: When planning interventions for patients with Parkinson's disease, it can be helpful for clinicians to be aware of patients' perspectives regarding their sense of responsibility to perform occupations. The use of a systematic sequence of challenging occupations with responsibility attributes ranging from less complex to more complex can help enhance patient occupational participation.

Comparing Telerehabilitation and In-Person Interventions in School-Based Occupational Therapy for Specific Learning Disorder A Randomized Controlled Trial

Objective

This study investigated the efficacy of telerehabilitation (TR) in school-based Occupational Therapy (OT) for children with Specific Learning Disorder (SLD), focusing on occupational competence and parental satisfaction, aiming to contribute empirical insights to the discourse on the educational well-being of this population.

Materials & Methods

The study adopted a Randomized Controlled Trial (RCT) design involving 31 children diagnosed with SLD, implementing TR and in-person interventions alongside a control group. Outcome measures included the School Self-Concept Inventory, Child Occupational Self-Assessment (COSA), and Canadian Occupational Performance Measurement (COMP), analyzed using descriptive and inferential statistics (ANOVA, post hoc tests).

Results

Both TR and in-person interventions exhibited significant enhancements in academic self-efficacy (F=23.96, p<0.001, Partial ȵ²=0.461), occupational competence (F=70.59, p<0.001, Partial ȵ²=0.716), and parent satisfaction (F=17.03, p<0.001, Partial ȵ²=0.378) compared to the control group. Notably, no significant differences emerged between the TR and in-person groups, emphasizing their comparable effectiveness in improving outcomes.

Conclusion

In conclusion, the study demonstrated the efficacy of TR and in-person interventions in school-based OT for children with SLD. The cohesive outcomes in academic self-efficacy, occupational competence, and parental satisfaction highlight TR as a versatile modality. This research, grounded in robust methodology, encourages further exploration of TR's transformative role in enhancing the holistic well-being of children with SLDs.

Antibiotic resistance pattern and pathological features of avian pathogenic Escherichia coli O78:K80 in chickens

Abstract Avian pathogenic Escherichia coli (APEC) induces colibacillosis, an acute and systemic disease, resulting in substantial economic losses in the poultry sector. This study aimed to investigate the antibiotic resistance pattern associated with frequent virulence gene distribution in APEC O78:K80 that may cause pathological alterations in chickens. The antibiogram profile showed high resistance to erythromycin, chloramphenicol, tetracycline, ampicillin, and co-trimoxazole, followed by intermediate resistance to ciprofloxacin, levofloxacin, enrofloxacin, norfloxacin, nitrofurantoin, and doxycycline hydrochloride, and sensitive to amikacin, streptomycin, gentamicin, and colistin. Virulence gene distribution identifies eight (irp-2, iutA, ompT, iss, iucD, astA, hlyF, iroN) genes through a conventional polymerase chain reaction. APEC O78:K80 caused significantly high liver enzyme concentrations, serum interleukin-6 and tumor necrosis factor-alpha levels in experimental birds. Also, infected birds have hypoproteinemia, hypoalbuminemia, and hyperglobulinemia. Necropsy examination revealed fibrinous perihepatitis and pericarditis, congested lungs, intestinal ecchymotic hemorrhages and necrotizing granulomatosis of the spleen. Histopathological examination depicted hepatocellular degeneration, myocardial necrosis, interstitial nephritis, intestinal hemorrhages and lymphopenia in the spleen. This study is the first evidence to assess the antibiotic resistance profile linked with virulence genes and clinicopathological potential of APEC O78:K80 in chickens in Pakistan, which could be a useful and rapid approach to prevent and control the disease by developing the control strategies.

A comparison of the effects of occupation-based interventions with and without responsibility feedback and conventional interventions on participation in people with idiopathic Parkinson's disease: study protocol for a randomized controlled trial

BACKGROUND

Parkinson's disease (PD) is a neurodegenerative disorder with debilitating motor and non-motor symptoms which affect participation in meaningful occupations. Occupation-based interventions can improve participation in people with PD. Evidence for incorporating structured and intensive occupational therapy by considering the concept of responsibility is lacking for this population. This trial will compare the effects of occupation-based interventions with and without responsibility feedback and conventional interventions on participation in people with idiopathic PD.

METHODS

A total of 45 people with PD, between 35 and 85 years old and Hoehn and Yahr stages between I to III, will be recruited from movement disorder centers for this three-armed study. Participants will be randomized into three groups (occupation-based interventions with responsibility feedback, occupation-based interventions without responsibility feedback, and conventional interventions). All participants will receive intervention for 24 sessions during a period of 12 weeks (2 sessions per week). The primary outcome measure will be participation satisfaction. Participation frequency and restriction, self-perceived performance, performance satisfaction, motivation, volition, sense of agency, responsibility, physical activity, community integration, activities of daily living (ADL), instrumental ADL, upper extremity function, balance, fatigue, and quality of life will be measured as secondary outcome measures. All outcomes will be measured at baseline, session 9, session 17, post-intervention (week 13), and follow-up (week 25).

DISCUSSION

This home-based high-intensity, structured, client-centered, and occupation-based intervention will be conducted by utilizing the concept of responsibility. This proposed trial may result in enhanced participation that would benefit other motor and non-motor symptoms in people living with PD. Findings from this proposed study are expected to expand the knowledge of clinicians and help them in evidence-based decision-making processes.

Low-dose carboplatin modifies the tumor microenvironment to augment CAR T cell efficacy in human prostate cancer models

Chimeric antigen receptor (CAR) T cells have transformed the treatment landscape for hematological malignancies. However, CAR T cells are less efficient against solid tumors, largely due to poor infiltration resulting from the immunosuppressive nature of the tumor microenvironment (TME). Here, we assessed the efficacy of Lewis Y antigen (LeY)-specific CAR T cells in patient-derived xenograft (PDX) models of prostate cancer. In vitro, LeY CAR T cells directly killed organoids derived from androgen receptor (AR)-positive or AR-null PDXs. In vivo, although LeY CAR T cells alone did not reduce tumor growth, a single prior dose of carboplatin reduced tumor burden. Carboplatin had a pro-inflammatory effect on the TME that facilitated early and durable CAR T cell infiltration, including an altered cancer-associated fibroblast phenotype, enhanced extracellular matrix degradation and re-oriented M1 macrophage differentiation. In a PDX less sensitive to carboplatin, CAR T cell infiltration was dampened; however, a reduction in tumor burden was still observed with increased T cell activation. These findings indicate that carboplatin improves the efficacy of CAR T cell treatment, with the extent of the response dependent on changes induced within the TME.

Effects of an Occupation-Based Intervention on Hand and Upper Extremity Function, Daily Activities, and Quality of Life in People With Burn Injuries: A Randomized Controlled Trial

IMPORTANCE

Occupational performance and function are affected in people with burn injuries to the hand and upper extremity; this can lead to the development of some disabilities and endanger quality of life.

OBJECTIVE

To investigate the effects of occupation-based intervention on hand and upper extremity function, daily activities, and quality of life in people with burn injuries.

DESIGN

Randomized controlled trial.

SETTING

Specialized burn hospital in Iran.

PARTICIPANTS

Patients (N = 20) with burn injuries to the hand and upper extremity.

INTERVENTIONS

The control group received only traditional rehabilitation, and the intervention group received traditional rehabilitation and took part in the Cognitive Orientation to daily Occupational Performance (CO-OP) protocol (18 sessions, 45 min/day, for both groups).

MEASURES

Assessments included the CO-OP; Michigan Hand Outcomes Questionnaire; Shortened Disabilities of the Arm, Shoulder and Hand Questionnaire; Modified Barthel Index; World Health Organization Quality-of-Life Scale-Brief; a visual analogue scale; measurements with a goniometer and dynamometer; and the figure-of-eight method. These evaluations were conducted with both groups before the rehabilitation program commenced and at Wk 2, 6, and 14 (follow-up).

RESULTS

The results showed that there were notable changes in all the study variables except edema in both groups. However, these changes (p [V] ≤ .05) were not statistically significant between the two groups.

CONCLUSIONS AND RELEVANCE

According to the results, the occupation-based interventions are as effective as traditional therapeutic interventions for the improvement of hand and upper extremity function, ability to perform daily activities, and quality of life in people with burn injuries. What This Article Adds: The CO-OP protocol, as an occupation-based intervention, can improve hand performance, ability to perform daily activities, and quality of life in people with burn injuries, and thus it can be useful in rehabilitation clinics.

Consensus on Feedback Statements That Create Responsibility Among People With Parkinson's Disease: A Delphi Study

IMPORTANCE

Sense of agency is associated with a sense of responsibility, which is essential to performing goal-directed occupations.

OBJECTIVE

To reach consensus on a set of extrinsic feedback statements that have the potential to create a sense of responsibility among patients with neurological disorders in the course of performing daily or social occupations.

DESIGN

Anonymous Delphi study with two rounds with international experts and one round with Irani patients with Parkinson's disease (PD).

SETTING

Electronic survey.

PARTICIPANTS

One hundred experts and 73 patients with idiopathic PD.

OUTCOMES AND MEASURES

Experts and patients anonymously rated (5 = strongly agree/very effective, 4 = agree/effective, 3 = neither agree nor disagree/uncertain, 2 = disagree/ineffective, 1 = strongly disagree/very ineffective) their level of agreement with each survey statement and the effectiveness of each statement in creating a sense of responsibility in the course of performing daily or social occupations. Consensus was set as an interquartile range of ≤1 and ≥70% agreement in two adjacent categories of a Likert scale.

RESULTS

In the experts' first round, consensus was reached on the level of agreement and effectiveness of 18 statements. In the second round, final consensus was achieved on all statements. In the one patient round, patients reached consensus on all statements. Finally, 34 statements were rated as 4 or 5 in terms of agreement and effectiveness, based on the opinions of experts and patients.

CONCLUSIONS AND RELEVANCE

This study has produced a collection of feedback statements that might be useful in occupation-based interventions. What This Article Adds: Extrinsic responsibility feedback delivered while administering occupation-based interventions may increase volition, motivation, and engagement.

Occupations to Enhance Responsibility Among Patients With Parkinson's Disease: An International Delphi Study

IMPORTANCE

The ability to perform voluntary actions is disrupted in Parkinson's disease (PD). Voluntary activities play a critical role in generating sense of agency, which underpins the concept of responsibility for people's daily occupations and their outcomes. According to this concept, the dearth of research regarding the concept of responsibility in rehabilitation hampers practitioners in delivering evidence-based care.

OBJECTIVE

To generate a list of occupations that enhance an inherent sense of responsibility among people with PD that is based on consensus among experts.

DESIGN

An anonymous and iterative Delphi study with two rounds.

SETTING

Electronic survey.

PARTICIPANTS

One hundred sixteen experts participated in the first round of the study, and 95 participated in the second round.

OUTCOMES AND MEASURES

Panelists rated the level of inherent responsibility in each occupation and the importance of types of patient-related information on a 5-point Likert scale. Consensus was defined as reaching an interquartile range of >1.

RESULTS

In the first round, consensus was reached on 19 occupations and all 38 types of patient-related information. Also, an additional 15 occupations and 16 types of patient-related information were added to the lists. Consensus was reached for all occupations and patient-related information presented in the second round.

CONCLUSIONS AND RELEVANCE

Our results indicate that 61 occupations were deemed to enhance a moderate to a very high inherent sense of responsibility among people with PD. In addition, a wide range of patient-related information is considered very important or important while these occupation-focused interventions are delivered. What This Article Adds: Subjective knowledge of one's actions and their consequences lies behind people's daily occupations. Considering this knowledge when administering occupation-focused interventions can be beneficial for individuals with PD.

Comparison of the DiagnosticAccuracy of Common Balance Measurement Tools in Community-Dwelling OlderAdults

Introduction: Balance screening has been identified as a major predictor of falls in the elderly. The current study compares the diagnostic accuracy of various balance instruments in community-dwelling older adults. Materials and Methods: In this cross-sectional study, 145 older adults were recruited. The Berg balance scale (BBS), Fullerton advanced balance (FAB) scale, dynamic gait index (DGI), performance-oriented mobility assessment (POMA), timed up and go (TUG) test, gait speed, step length, step test, and single item question were administered. The receiver operating characteristics curve analysis was used to calculate diagnostic accuracy. Results: All single-item tools had moderate diagnostic accuracy (area under the curve [AUC]=0.76-0.89) and all multi-item tools had high diagnostic accuracy (AUC=0.91-0.95) when using the recommended cut-off point of 45 for BBS. All multi-item tools maintained high to moderate diagnostic accuracy (AUC=0.85-1.00) in all thresholds while using BBS severity cut-off points. The FAB scale showed the highest diagnostic accuracy (AUC=0.95) among all assessment tools. Single-item question scores (Wald=22.61, df=1, P=0.0001, Exp(B)=8.82) were significant as covariates in the regression model. Conclusion: For older adults with or without a history of falling, the FAB scale demonstrated the highest diagnostic accuracy. Along with single-item tools, the FAB scale may be a preferred multi-item tool.

The effects of supervised and non-supervised upper limb virtual reality exercises on upper limb sensory-motor functions in patients with idiopathic Parkinson's disease

BACKGROUND

Impairments of upper limb (UL) sensory-motor functions are common in Parkinson's disease (PD). Virtual reality exercises may improve sensory-motor functions in a safe environment and can be used in tele-rehabilitation. This study aimed to investigate the effects of supervised and non-supervised UL virtual reality exercises (ULVRE) on UL sensory-motor functions in patients with idiopathic PD.

METHODS

In this clinical trial study, 45 patients with idiopathic PD (29 male) by mean ± SD age of 58.64 ± 8.69 years were randomly allocated to either the control group (conventional rehabilitation exercises), supervised ULVRE or non-supervised ULVRE. Interventions were 24 sessions, 3 sessions/week. Before/after of interventions and follow-up period all assessment was done. Hand Active Sensation Test and Wrist Position Sense Test were used for assessing UL sensory function. Gross and fine manual dexterity were assessed by Box-Block Test and Nine-Hole Peg Test, respectively. Grip and pinch strength were evaluated by a dynamometer and pinch gauge, respectively.

RESULTS

The results showed significant improvement in discriminative sensory function (HAST-weight and HAST-total), wrist proprioception, gross manual dexterity and grip strength of both less and more affected hands as well as fine manual dexterity of the more affected hand in the three groups in patients with idiopathic PD (P < 0.05).

CONCLUSION

The results of this study indicated that both supervised and non-supervised ULVRE using the Kinect device might potentially improve some aspects of UL sensory-motor functions in patients with PD. Therefore, ULVRE using the Kinect device can be used in tele-rehabilitation, especially in the current limitations induced by the COVID-19 pandemic, for improving UL functions in patients with PD.

Apathy exacerbates postural control impairments in stroke survivors: The potential effects of cognitive dual-task for improving postural control

Apathy is a stressor and debilitating common condition for both stroke survivors and their caregivers. However, its effects on the postural control of these patients have not yet been investigated. Improved postural stability through withdrawing attention from postural control by concurrent cognitive task (i.e. dual-task condition) has been reported previously, but the effect of apathy, as a confounding factor, remains unknown. This study aimed to examine the effects of apathy and dual-task condition on postural control of chronic stroke survivors from biomechanical and neurophysiological perspectives. Twenty non-apathetic stroke survivors, 20 apathetic stroke survivors, and 20 sex-, age-, weight-, and height-matched healthy subjects were assessed using different postural sway measures and electromyography activity of ankle and hip muscles while quietly standing on rigid and foam surfaces under single-task, easy dual-task, and difficult dual-task conditions. The results showed postural instability and neuromuscular stiffening of stroke survivors, particularly apathetic stroke survivors, compared with healthy controls as evidenced by significantly greater postural sway measures and increased co-contraction of ankle muscles as well as hip muscles. Notably, concurrently performing a cognitive task significantly reduced postural instability and neuromuscular stiffening in chronic stroke survivors even in those with apathy. In conclusion, apathy exacerbates postural control impairments in chronic stroke survivors promoting an inefficient conscious mode of postural control. It is recommended that distracting the attention away from postural control by performing a concurrent cognitive task can be considered an effective strategy while designing interventions for improving postural control in apathetic stroke survivors.

Validation of the Persian Version of the Engagement in Meaningful Activities Survey (EMAS) in an Iranian Stroke Population: Predictors of Participation in Meaningful Activities

IMPORTANCE

The inability to participate in meaningful activities is one of stroke survivors' main difficulties and has a negative effect on their satisfaction and quality of life.

OBJECTIVE

To assess the reliability and validity of the Persian version of the Engagement in Meaningful Activities Survey (EMAS-P) and predictors of participation in meaningful activity among chronic stroke survivors.

DESIGN

Cross-sectional.

SETTING

Medical and rehabilitation centers.

PARTICIPANTS

One hundred twenty-three people (75 men, 48 women) with chronic stroke.

OUTCOMES AND MEASURES

Participants were evaluated with the EMAS-P, Satisfaction With Life Scale (SWLS), Center for Epidemiologic Studies Depression Scale, Purpose in Life Test-Short Form (PIL-SF), 36-Item Short Form Health Survey (SF-36), and Life Satisfaction Index-Z (LSI-Z).

RESULTS

The EMAS-P showed good internal consistency (Cronbach's α = .95) and test-retest reliability (intraclass correlation coefficient = .87 for EMAS-P total score). Test-retest reliability for each EMAS-P item was moderate (κ = .40-.65). A significant correlation between the EMAS-P and PIL-SF (r = .86), SWLS (r = .83), LSI-Z (r = .75), and SF-36 subscales (rs = .52-.83) indicated the appropriate convergent validity. The EMAS-P's discriminative validity was also confirmed for age, depression level, and disability level among people with chronic stroke. Depression, disability level, gender, and fatigue were significant predictors of EMAS-P score.

CONCLUSIONS AND RELEVANCE

The results indicate that the EMAS-P has acceptable reliability and validity among Iranian people with chronic stroke. Moreover, the EMAS-P showed good discriminant validity for age, depression, and disability level among them. What This Article Adds: The EMAS-P is a reliable and valid scale for assessing the engagement of Iranian chronic stroke survivors in meaningful activities and thus should be helpful in both clinical research and practice.

Exploring the contribution of mechano-sensing to cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is an inherited cardiac condition associated with diastolic dysfunction and sudden cardiac death. Disease genes for HCM are traditionally coding for proteins involved in force generation. More recently, it has emerged that variants in genes coding for proteins involved in biomechanical stress-signalling can also cause HCM.

One such protein is filamin C, with proposed mechano-sensing functions in the heart. Within the protein, the immunoglobulin-like domain 20 (Ig20) may play a crucial role in mediating binding to muscle specific ligands. While the mechano-sensing functions of filamin C have been investigated well in skeletal muscle, the underlying cardiac disease mechanisms are not completely understood.

Aim

This work attempts to provide insights into the role of filamin C in cardiac mechano-sensing and dissect disease pathways leading to HCM in the presence of the FLNC variants in Ig20.

Methods

Using mass spectrometry, we aimed to provide a detailed analysis of the proteome of mice carrying the filamin C variant, using ventricular tissue samples from 14wk old homozygous mice. Samples were subject to molecular biology technical and underwent subcellular fractionation (n = 6 per genotype) and were investigated by label-free mass spectrometry.

Results

Utilising whole genome sequencing, a heterozygous FLNC missense variant in Ig20 was identified in a three-generation family affected by HCM. Mice carrying this variant recapitulate molecular features of HCM in the homozygous setting. Three proteins (FLNC, MYH7, MYOT) were found to be upregulated in the myofilament-enriched fraction. Up-regulations of key proteins were found to relocalise towards load-baring sites.

Conclusion

Our data indicate that changes in filamin C and its binding partners expression and localisation are involved in the pathogenesis of HCM in this mouse model.

Minimal and robust clinically important difference of three fatigue measures in chronic stroke survivors

BACKGROUND

Fatigue assessment scale (FAS), fatigue subscale of the Profile of Mood States (POMS-F), and vitality subscale of the Short Form Health Survey (SF-36-VT) are among the first and most widely used adapted tools for assessing post-stroke fatigue.

OBJECTIVE

To identify the minimal clinically important difference (MCID) and robust clinically important difference (RCID) of FAS, POMS-F, and SF-36-VT in stroke survivors.

METHODS

Participants completed the FAS, POMS-F, and SF-36-VT before and after receiving 6-week intervention including graded activity training and pacing therapy. MCID was calculated using the distribution-based and anchor-based methods. Further, accuracy, sensitivity, and specificity of calculated values using the distribution-based method were used for determining RCID.

RESULT

A total of 124 stroke survivors participated in this study. MCID for FAS, POMS-F, and SF-36-VT was found to be 4.86, 3.32, and -10.10 (using score change) and 3.5, 2.5, and -10.5 (using ROC analysis), respectively. Using the distribution-based method, the MCID value obtained for the FAS was in the range of 3.16 to 8.76, for the POMS-F was in the range of 1.49 to 5.63, and for the SF-36-VT was in the range of -15.43 to -5.58. ½SD for FAS, ½ SD and 1.96 SEM for POMS-F, and 1.96 SEM and SD for SF-36-VT showed the best discriminative ability to use as the RCID.

CONCLUSIONS

The MCID and RCID were calculated for FAS, POMS-F, and SF-36-VT using different methods. The results can be used by researchers and clinicians for interpreting their findings in subjects similar to those who participated in this study.

Assessing growth performance, morphometric traits, meat chemical composition and cholesterol content in four phenotypes of naked neck chicken

The present study was conducted to assess the growth performance, morphometric traits, muscle chemical composition and cholesterol content in four phenotypes of naked neck chicken (black, white-black, light brown and dark brown). A total of 320-day-old chicks, 80 from each phenotype, were randomly stratified into 20 replicates (16/replicate), according to a completely randomized design. The results showed higher final body weight, weight gain, and better FCR in both light brown and dark brown phenotypes whereas time of gains was found to be greater in dark brown phenotype. Keel length and shank circumference were greater in dark brown whereas wing spread was found to be higher in light brown phenotype. Drumstick circumference and body length did not show any significant differences (P > 0.05) across the phenotypes. Dry matter was found to be higher in white black, crude protein in black, white black and dark brown, moisture in light brown, and cholesterol content in black whereas ether extract and ash content were found to be greater in black and white black phenotypes. In conclusion, both light brown and dark brown phenotypes showed superior growth performance and morphometric traits. Similarly, from a health point of view, the dark brown and light brown phenotypes seem superior because their cholesterol content was low. Thus, it is strongly recommended that there should be a conscious effort to improve economically important traits of the light and dark brown birds to be used as dual-purpose slow growing chicken, especially in developing countries.

Symmetric and asymmetric bimanual coordination and freezing of gait in Parkinsonian patients in drug phases

Freezing of gait (FOG) is a debilitating symptom in patients with Parkinson's disease (PD), which may be associated with motor control impairments in tasks other than gait. This study aimed to examine whether symmetric and asymmetric bimanual coordination is impaired in PD with FOG (PD +FOG) patients and whether dual-task and drug phases may affect bimanual coordination in these patients. Twenty PD +FOG patients, 20 PD patients without FOG (PD -FOG) performed symmetric and asymmetric functional bimanual tasks (reach to and pick up a box and open a drawer to press a pushbutton inside it, respectively) under single-task and dual-task conditions. PD patients were evaluated during on- and off-drug phases. Kinematic and coordination measures were calculated for each task. PD +FOG patients demonstrated exacerbated impairments of bimanual coordination while performing goal-directed bimanual tasks, which was more evident in the asymmetric bimanual task and under dual-task conditions, highlighting the need for rehabilitation interventions for bimanual tasks that include different cognitive loads in these patients. Interestingly, 25% and 5% of participants in the PD +FOG and -FOG groups developed upper limb freezing 2 years later, respectively. This study aimed to examine whether symmetric and asymmetric bimanual coordination is impaired in Parkinson's disease with freezing of gait (PD +FOG) patients and whether dual-task and drug phases may affect bimanual coordination in these patients. PD +FOG patients demonstrated exacerbated impairment of bimanual coordination while performing goal-directed bimanual tasks, highlighting the need for rehabilitation interventions for bimanual tasks that include different cognitive loads in these patients.

The Development and Validation of a Scale for the Activities of Daily Living in Iranian Children

Introduction: Activities of Daily Living (ADL), as an ultimate goal of rehabilitation, rely on cultural and environmental factors. This study aimed to develop a questionnaire based on the occupational therapy practice frame to accurately evaluate Iranian children’s occupational performance. Methods: This scale was developed in two phases of planning and construction. The planning phase involved a literature review and a collection of the available evaluation tools in the area. The advice of two expert panels was used to develop a preliminary 87-item questionnaire. In the construction phase, 40 parents were surveyed to assess the popularity of the activities in Iran. After a face to content validation, the final version of the questionnaire was prepared with 93 items. Results: The final 93-item questionnaire was used to assess the ADL of 3-6-year-old children. The 93 items, selected according to criteria found in the literature and the panel of experts, were categorized into six ranges of occupational therapy practice framework (bathing/washing/personal hygiene, toileting, dressing, eating/feeding, functional mobility, and others). Conclusion: The ADL in Iranian children is a practical and culturally relevant tool for measuring the occupational performance of Iranian children. It can be used in clinical and population-based research.

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.

Falls Efficacy Scale and Single Item Question: Screening Accuracy for Older Adults Residing in Nursing Homes

Objectives: The Falls Efficacy Scale (FES) has been developed to evaluate self-efficacy in avoiding falling during Basic Activities of Daily Living (BADL) and Single Item Question (SIQ) evaluates fear of falling (FOF) by asking a single question. These tools have some pros and cons, therefore, the present study aimed to evaluate and compare screening accuracy of Falls Efficacy Scale (FES) and Single Item Question (SIQ) in measuring FOF for older adults.Methods: A total of 100 older adult residents of nursing homes (males: N = 63) were evaluated with Falls Efficacy Scale-International (FES-I), FES, and SIQ via interview. Cutoff points and validity parameters were calculated for the FES and SIQ by using FES-I as a criterion measure.Results: In a moderate FOF threshold, the sensitivity rate of 81.82% and 43.18% were obtained for FES and SIQ, respectively. High sensitivity and specificity rate were obtained for both FES (sensitivity and specificity: 100%) and SIQ (sensitivity: 94.44%; specificity: 90%) in severe FOF threshold.Conclusions: The results of this study indicated that, compared to the SIQ, the FES is a better tool to identify FOF in both moderate and severe thresholds in first screening.Clinical Implications: The FES is a valid and sensitive tool to identify FOF in older adults.

Psychometric properties of dexterity questionnaire-24 in Iranian chronic stroke survivors

INTRODUCTION

Dexterity is one of the most critical upper extremity functions that may be impaired in chronic stroke survivors. This study aimed to investigate the psychometric properties of DextQ-24 in Iranian chronic stroke survivors.

METHOD

A total of 123 people with chronic stroke were included in the study. Internal consistency and test-retest reliability were assessed through Cronbach's alpha and Interclass Correlation (ICC), respectively. Dimensionality was performed by Exploratory Factor Analysis. In addition, to assess the convergent validity of DextQ-24, Box and Block Test, Motor Activity Log Questionnaire, ABILHAND Questionnaire, and Purdue Pegboard Test were used. Discriminant validity of DextQ-24 was measured between different stages of recovery (Brunnstrom stage). Acceptability was calculated by ceiling and floor effect.

RESULTS

Cronbach's alpha and ICC were 0.92 and 0.91, respectively. The 24 items of this questionnaire were classified into six components. Further, a moderate to strong correlation between the total score of DextQ-24 with other tools | r = 0.41-0.84 | was obtained. The results of discriminant validity approved the ability of the total score of DextQ-24 to separate different stages of recovery. The results also reported that this questionnaire did not have a significant ceiling and floor effect.

CONCLUSION

The results of our study showed that the Persian DextQ-24 has high reliability and a good convergent and discriminant validity in people with chronic stroke for dexterity measurement as a PROM questionnaire.

The Psychometric Features of the Patient-Rated Wrist Evaluation in Iranians With Scaphoid or Distal Radius Fracture

Objectives: It is essential to have a suitable instrument for the accurate assessments of pain and disability outcomes during interventions; such tools also help to guide hand surgery and rehabilitation programs in distal radius or scaphoid fracture. This study aimed to evaluate the psychometric features of the Patient-rated Wrist Evaluation (PRWE) questionnaire in Iranians with a history of scaphoid and distal radius fractures. Methods: One hundred and fifty subjects with a history of scaphoid and distal radius fractures were recruited from hospital-based outpatient hand clinics and completed the PRWE, 2 and 7 days after the occurrence of fracture. Additionally, the Quick-Disabilities of Arm, Shoulder, and Hand (Quick-DASH), the percentage of Wrist Range of Motion (%ROM), Visual Analog Scale Pain/Disability (VAS-P, VAS-D), Short-form Health Survey (SF-36) questionnaires, and pinch and grip strength (%) were conducted in the study participants. Cronbach’s alpha (α) coefficient and Intraclass Correlation Coefficient (ICC) were used to evaluate the internal consistency and test-retest reliability of the scale, respectively. Pearson or Spearman correlation coefficient was calculated for assessing the test’s construct validity. Results: No floor or ceiling effect was found. A very high test-retest reliability was obtained for the PRWE’s total score and subscores (ICC≥0.92). Cronbach’s α coefficient was obtained as ≥0.78 for the PRWE and its subscales. The PRWE total score presented a weak to strong (0.24-0.74) correlation with the average values of %ROM, %power grip, %pinch strength, VAS-P, VAS-D, SF-36, and Quick-DASH. The standard error of the measurement of PRWE total score equaled 3.93; its smallest real difference was 10.86. Discussion: The PRWE presented acceptable validity and excellent reliability for measuring disability and pain in individuals with the scaphoid and distal radius fractures in Iran.

Psychological Factors Predicting Participation in Meaningful Activities of People With Chronic Stroke

Background and Objectives: One of the most important areas in the rehabilitation of stroke patients is participation in meaningful activities. Participation of individuals with stroke in meaningful activities can increase their satisfaction and quality of life. The present study aimed to investigate the relationship between psychological factors and participation in meaningful activities as well as determining factors predicting participation in meaningful activities in patients with stroke. Methods: In this cross-sectional study, 100 people with chronic stroke participated which were selected from four rehabilitation centers using a convenience non-probability sampling method. Participants were assessed using Meaningful Activity Participation Assessment (MAPA), Satisfaction with Life Scale (SWLS), Center for Epidemiological Studies of Depression Scale (CED-S), 36-Item Short-Form Health Survey (SF-36), Visual Analogue Scale for Fatigue (VAS ‐ F), and Visual Analog Scale for Pain (VAS Pain). Results: The severity of depression had the highest relationship with the level of participation in meaningful activities. Also, the severity of depression, cognitive status, pain intensity, and severity of fatigue were identified as significant factors predicting the rate of participation in meaningful activities of patients with stroke. Conclusion: Participating in meaningful activities in people with stroke is an important issue and a major obstacle in the lives of people with stroke. As a result, identifying problems and making appropriate interventions to remove obstacles, such as fatigue, pain, cognitive problems, and most importantly depression should be a priority for professionals.

Handwriting status among Iranian primary school students: a cross-sectional study

Background/Aims

Handwriting difficulties among school students are the primary reason for referral to school-based occupational therapy. Appropriate criteria and a complete view of the students' handwriting status are lacking in Iran. The purpose of this study was to gather comprehensive information about handwriting issues for therapists and related disciplines in Iran.

Methods

In this cross-sectional study, the handwriting status of 1262 Persian-language elementary school students (grades 2 and 3) from governmental schools was surveyed using the Persian handwriting assessment tool.

Results

There were statistically significant differences in handwriting components between second and third grade students except for word size and text slant. Handwriting components were different between boys and girls, and between right- and left-handed writers. Regression analysis revealed a positive relationships between age and grade and most of the handwriting components.

Conclusions

The results of this study have implications for teachers, therapists and other specialists who work and research on handwriting status of typically healthy students and students who are disabled in Iran. Handwriting skills improve over time and it seems that girls and right-handed writers are better writers regarding legibility.

Anxiety and cognitive load affect upper limb motor control in Parkinson's disease during medication phases

Anxiety is among the most debilitating nonmotor symptoms of Parkinson's disease (PD). This study aimed to determine how PD patients with low and high levels of anxiety (LA-PD and HA-PD, respectively) compare with age- and sex-matched controls at the level of motor control of reach-to-grasp movements during single- and dual-task conditions with varying complexity. Reach-to-grasp movement kinematics were assessed in 20 LA-PD, 20 HA-PD, and 20 sex- and age-matched healthy controls under single- as well as easy and difficult dual-task conditions. Assessment of PD patients was performed during both the on- and off-drug phases. The results obtained during dual-task conditions reveal deficits in both reach and grasp components for all three groups (e.g., decreased peak velocity and delayed maximum hand opening). However, these deficits were significantly greater in the PD groups, especially in the HA-PD group. Although dopaminergic medication improved reach kinematics, it had no effect on grasp kinematics. The results of our study indicated that high levels of anxiety may enhance the inefficiency of upper limb motor control in PD patients, especially during high demanding cognitive conditions, and should, therefore, be considered in the assessment and planning of interventions for upper limb function in these patients.

National Guidelines for Cognitive Assessment and Rehabilitation of Iranian Traumatic Brain Injury Patients

BACKGROUND

Individuals with moderate to severe traumatic brain injury (TBI) often have prolonged cognitive impairments, resulting in long-term problems with their real-life activities. Given the urgent need for evidence-based recommendations for neuropsychological management of Iranian TBI patients, the current work aimed to adapt eligible international guidelines for cognitive assessment and rehabilitation of the TBI patients in Iran.

METHODS

The project was led by an executive committee, under the supervision of the Iranian Ministry of Health and Medical Education (MOHME). Following a systematic literature search and selection process, four guidelines were included for adaptation. Clinical recommendations of the source guidelines were tabulated as possible clinical scenarios for 90 PICO clinical questions covering all relevant phases of care. After summing up the scenarios, our initial list of recommendations was drafted according to the Iranian patients' conditions. The final decision-making, with the contribution of a national interdisciplinary panel of 37 experts from across the country, was conducted in two rounds using online and offline survey forms (Round 1), and face-to-face and telephone meetings (Round 2).

RESULTS

A total of 63 recommendations in six sections were included in the final list of recommendations, among which 24 were considered as key recommendations. In addition, some of the recommendations were identified as fundamental, meaning that proper implementation of the other recommendations is largely dependent on their implementation.

CONCLUSION

Iranian health policy makers and rehabilitation program managers are recommended to address some fundamental issues to provide the necessary infrastructure to set up an efficient cognitive rehabilitation service system.

The Correlation Between Reach and Grasp Kinematic Measures and Clinical Measures of Manual Dexterity in Patients With Parkinson Disease

Background and Objectives: To investigate the correlation between reach and grasp kinematic measures and clinical measures of gross and fine manual dexterity in patients with idiopathic Parkinson Disease (PD). Methods: Sixty patients (44 men, 16 women) with idiopathic PD (Mean±SD of age: 59.85±11.89 years) were recruited in this non-experimental cross-sectional study using a non-probability sampling method. Their gross and fine manual dexterity were assessed using the Box and Block Test (BBT) and Nine Hole Peg Test (NHPT), respectively. Also, reach and grasp kinematic measures (including normalized movement time, peak velocity, Maximum Grip Aperture [MGA], and percentage of movement time in which MGA occurred [PMGA]) were measured in the more affected hand. Results: The results showed a significant and moderate correlation between reach kinematic measures (i.e. normalized movement time and peak velocity) and both gross and fine manual dexterity assessed by BBT (P=0.000) and NHPT (P=0.000), respectively. However, there was not a significant correlation between grasp kinematic measures (i.e. MGA and PMGA) and gross manual dexterity measured by BBT (P>0.05) as well as fine manual dexterity assessed by NHPT (P>0.05). Conclusion: This study showed no to moderate correlation between reach and grasp kinematic measures and clinical measures of gross and fine manual dexterity in patients with PD, supporting the significance of multi-level evaluation using both clinical and kinematic measures in the evaluation of upper limb function in patients with PD.

Psychometric properties of Meaningful Activity Participation Assessment (MAPA) in chronic stroke survivors

BACKGROUND

Meaningful Activity Participation Assessment (MAPA) is an appropriate tool for assessing both objective and subjective aspects of participation.

OBJECTIVES

This study aimed to investigate the psychometric properties of MAPA in chronic stroke survivors.

METHODS

Translation of MAPA was done according to the standard protocol of forward-backward translation. One hundred and seven chronic stroke survivors participated in this study. In addition to the MAPA, they were assessed by Satisfaction With Life Scale (SWLS), Center for Epidemiologic Studies of Depression Scale (CES-D), Life Satisfaction Index-Z (LSI-Z), Purpose in Life Test-Short Form (PIL-SF), and 36-Item Short-Form Survey (SF-36). To investigate the test-retest reliability, 37 participants were reassessed by MAPA after two weeks. Reliability, construct and known-groups validity were evaluated for MAPA.

RESULTS

The results showed an acceptable internal consistency (Cronbach's α = 0.79) and good test-retest reliability (ICC = 0.92) of MAPA. A significant moderate to high correlation was found between the MAPA and PIL-SF, CES-D, LSI-Z, SWLS, and different subscales of SF-36 (r = 0.32-0.65). MAPA showed good ability to differentiate between young adults (age≤ 65 years) and older adults (age> 65 years) with chronic stroke (P = .005) as well as between chronic stroke survivors with different levels of disability (P < .001).

CONCLUSIONS

The MAPA has appropriate reliability and validity in chronic stroke survivors and is suggested to be used in research and clinical settings.

Validation and diagnostic accuracy of coin rotation task for manual dexterity and coordination in children with specific learning disorder

BACKGROUND

This study aimed at determining validity, reliability, and diagnostic accuracy of Coin Rotation Task (CRT) in assessing manual dexterity and coordination of children with specific learning disorder (SLD).

METHODS

In this non-experimental cross-sectional study, 120 children (typically developing children = 60, children with SLD = 60, mean age ± SD =9.18 ± 0.55) were recruited. Test-retest reliability and construct validity of CRT were assessed. Multivariate regression analysis was performed on CRT scores by considering age and gender as covariates and children with SLD with mild dexterity impairment and severe dexterity impairment (SDI) as outcome variables. Receiver-operating characteristics (ROC) curve analysis was carried out to derive validity parameters.

RESULTS

Test-retest reliability of the CRT scores in both subtests were excellent in children with SLD (ICC_2,1: 0.93-0.95) and good to excellent in typically developing children (ICC_2,1: 0.72-0.82). Acceptable construct validity of CRT was also found. The CRT cut-off points were 23 (sensitivity= 89.29%, specificity= 70.37%) and 28 (sensitivity= 80.33%, specificity= 86.36%) for discriminating children with SLD and SDI from typically developing children in dominant and non-dominant hand, respectively.

CONCLUSIONS

The present study indicated good to excellent test-retest reliability, acceptable validity, and high diagnostic accuracy for diagnosing children with SLD based on their dexterity impairment level.Implications for RehabilitationThe Coin Rotation Task (CRT) was modified and validated for use in children.The CRT is a reliable and valid tool with high diagnostic accuracy.The CRT has a good ability for discriminating children with specific learning disorder with severe dexterity impairment form typically developing children.Treatment plans and research designs can be performed by using this valid, reliable, and easy to administer tool.

The Persian Handwriting Assessment Tool for Primary School-Aged Children: Further Validation

Background

Handwriting problems are one of the common problems among students in the early years of education. The current study aimed to determine further validation aspects of the Persian Handwriting Assessment Tool (PHAT) in primary school-aged children.

Methods

The current methodological study was conducted on 452 healthy 8-10-year-old students in Tehran, Iran, selected via random cluster sampling method. Inclusion criteria were native Persian-speaking and no documented physical and mental impairments. Construct and structural validities were established by exploratory factor analysis (EFA) using principal axis factoring with Promax rotation and confirmatory factor analysis (CFA), respectively. Criterion validity was examined by expert opinion as the gold standard using Pearson correlation test. Internal consistency, test-retest, and inter-rater reliability were examined using Cronbach's alpha and intra-class correlation (ICC). Test-retest had a seven-day interval.

Results

The EFA results indicated two separate factors in the copying and dictation domains. Speed and orthographic error and size were considered as separate items. The CFA confirmed the factor structure. Criterion validity revealed low to moderate correlation (formation: 0.548, P<0.001; 0.503, P<0.001, spacing: 0.553, P<0.001; 0.307, P=0.030, alignment: 0.442, P<0.001; 0.358, P=0.011, size: -0.376, P=0.007; -0.445, P<0.001, and slant: 0.360, P=0.010; 0.372, P=0.008) in copying and dictation domain, respectively. Acceptable internal consistency (Cronbach's alpha: 0.72-0.99), excellent test-retest (ICC: 0.76-0.99), excellent inter-rater reliability between teachers (ICC: 0.86-0.95), and good to excellent inter-rater reliability between teachers and the occupational therapist (ICC: 0.60-0.95) were reported.

Conclusion

The results indicated that the PHAT was a valid and reliable tool for assessing handwriting in primary school-aged children.

Assessment tools to evaluate Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) in older adults: A systematic review

Background: Given the increasing population of older adults in different societies, it is important to take into account the needs of them. In this regard, the most important things that are closely related to their quality of life are their ability in evaluating Activity of Daily Living (ADL) and Instrumental Activity of Daily Living (IADL) performances. The aims of the present study were to identify the outcome measures specific to the ADL and IADL for older adults and to investigate the psychometric properties of these measures.

Methods: This is a systematic review done on the articles published between June 2019 and February 2019. Articles in English language from these database included: Medline, PubMed, Google Scholar, CINAHL, OVID Medline, Cochrane, ProQuest, Up to Date, Web of Science, OT search, OT direct, Pedro, SID, Magiran, Iran Medex, MEDLIB and Iran doc. English keywords included: "Activity of Daily Living (ADL)", "Instrumental Activity of Daily Living (IADL)", "assessment", "evaluation", "aging", "ageing", "older adults", "elders", "Basic Activity of Daily Living (BADL)", "Advanced Activity of Daily Living (AADL)", "basic functions", "self-care", "mobility", "independency", "dependency", "occupational therapy", "physical therapy", "rehabilitation". The Consensusbased Standards for the selection of health Measurement Instruments (COSMIN) checklist were employed to investigate the psychometric properties of the studies.

Results: Of the initial 482 studies considered, 13 studies met the inclusion criteria that assess the ADL and IADL performance of older adults. In this regard, 8 outcome measures were found especially for ADL assessment and 5 for IADL assessment.

Conclusion: Most of the assessment tools are performance-based and have been developed in especial contexts and especial groups of older adults. Some have been used frequently in different contexts but some were used less than others. None of these measures has been developed in Iran. So, for better assessment and having better intervention plans for older adults in Iran, it is suggested to develop an instrument that is especially designed for Iranian context.

Sensory retraining improves light touch threshold of the paretic hand in chronic stroke survivors: a single-subject A-B design

Background: Light touch, one of the primary and basic sensations, is often neglected in sensory retraining programmes for stroke survivors.Objective: This study aimed to investigate the effects of sensory retraining on the light touch threshold of the hand, dexterity and upper limb motor function of chronic stroke survivors.Methods: Five chronic stroke survivors with sensory impairment participated in this single-subject A-B design study. In baseline (A) phase, they only received standard rehabilitation. In the treatment (B) phase, they received a 6-week sensory retraining intervention in addition to standard rehabilitation. In both phases, they were evaluated every 3 days. Light touch threshold, manual dexterity and upper limb motor function were assessed using Semmes-Weinstein Monofilaments, Box-Block Test and Fugl-Meyer Assessment, respectively. Visual analysis, nonparametric Mann-Whitney U test and, c-statistic were used for assessing the changes between phases.Results: All participants indicated changes in trend or slope of the total score of light touch or both between the two phases. The results of the c-statistic also showed the statistical difference in the total score of light touch between baseline and treatment in all participants (p < 0.001). Also, the results of the c-statistic and Mann-Whitney U test supported the difference of manual dexterity and motor function of the upper limb between baseline and treatment in all participants (p < 0.001).Conclusion: Current findings showed that sensory retraining may be an effective adjunctive intervention for improving the light touch threshold of the hand, dexterity and upper limb motor function in chronic stroke survivors.

Oro-Dental Health of Patients with Chronic Hepatic Failure

BACKGROUND

Patients with chronic liver failure (CLF) faced serious medical conditions including the oral cavity.

OBJECTIVE

To investigate the prevalence of oral mucosal lesions, saliva flow rate, and dental complications in candidates of liver transplant surgery.

METHODS

In this cross-sectional study, oral and dental health of 77 patients with CLF and 77 healthy individuals were assessed for oral mucosal lesions, salivation rate, DMFT (decayed, missing, filled teeth) index, and bone level. To carefully determine the indices and examine the patients thoroughly, a panoramic radiography was also taken from each participant.

RESULTS

The frequency of oral mucosal lesions in patients was significantly (p<0.001) higher than the comparison group. The most frequent lesion identified was angular cheilitis followed by candidiasis. The mean saliva flow rate in the patients (0.85 g/min) was also significantly (p<0.001) lesser than that in healthy individuals (1.58 g/min). The DMFT index and bone level were not significantly different between the two groups. Nor was a correlation between the MELD score and each of DMFT index, bone loss, or oral mucosal lesions.

CONCLUSION

Mucosal lesions, especially fungal-related lesions, are more prevalent in the oral cavity of patients with CLF. The saliva production rate is reduced due to various medications used in this group. Patients with CLF are prone to oral infections and a thorough oro-dental examination is crucial in this group of patients. Vigorous oral hygiene instructions should be offered to liver cirrhosis individuals.

The effect of sensory-motor training on hand and upper extremity sensory and motor function in patients with idiopathic Parkinson disease

STUDY DESIGN

Blinded randomized controlled trial.

INTRODUCTION

Patients with Parkinson disease (PD) have sensory problems, but there is still no accurate understanding of the effects of sensory-motor interventions on PD.

PURPOSE OF THE STUDY

To investigate the effects of sensory-motor training (SMT) on hand and upper extremity sensory and motor function in patients with PD.

METHODS

Forty patients with PD were allocated to the SMT group or the control group (CG) (mean ages ± standard deviation: SMT, 61.05 ± 13.9 years; CG, 59.15 ± 11.26 years). The CG received the common rehabilitation therapies, whereas the SMT group received SMT. The SMT included discrimination of temperatures, weights, textures, shapes, and objects and was performed 5 times each week for 2 weeks.

RESULTS

Significantly reducing the error rates in the haptic object recognition test (dominant hand [DH]: F = 15.36, P = .001, and effect size [ES] = 0.29; nondominant hand [NDH]: F = 9.33, P = .004, and ES = 0.21) and the error means in the wrist proprioception sensation test (DH: F = 9.11, P = .005, and ES = 0.19; NDH: F = 13.04, P = .001, and ES = 0.26) and increasing matched objects in the hand active sensation test (DH: F = 12.15, P = .001, and ES = 0.24; NDH: F = 5.03, P = .03, and ES = 0.12) founded in the SMT. Also, the DH (F = 6.65, P = .01, and ES = 0.15), both hands (F = 7.61, P = .009, and ES = 0.17), and assembly (F = 7.02, P = .01, and ES = 0.15) subtests of fine motor performance, as well as DH (F = 10.1, P = .003, and ES = 0.21) and NDH (F = 8.37, P = .006, and ES = 0.18) in upper extremity functional performance, were improved in the SMT.

DISCUSSION

SMT improved hand and upper extremity sensory-motor function in patients with PD.

CONCLUSION

The SMT group showed improved sensory and motor function. But these results were limited to levels 1 to 3 of the Hoehn and Yahr Scale.

Predictive accuracy of performance oriented mobility assessment for falls in older adults: A systematic review

Background: Performance Oriented Mobility Assessment (POMA) is a commonly used screening tool for identifying patients at risk of falling. The purpose of this systematic review was to determine the overall predictive accuracy of POMA for falls in community-dwelling older adults. This review could provide useful information to use POMA in both research and clinical settings.

Methods: In this study, PubMed, EMBASE, CINHAL, Cochrane Library, EBSCO, and SCOPUS were searched to identify studies published from 1987 to 2017 that aimed at validating POMA and reporting predictive value with sufficient data to calculate sensitivity and specificity. The methodological quality of the selected studies was assessed using the Quality Assessment of Diagnostic Accuracy studies (QUADAS-2).

Results: Of the 121 identified studies, 12 met the inclusion criteria and were entered in the final analysis. Fall rate ranged from 5% to 61% in the included studies. The POMA cutoff point for discriminating fallers from non-fallers varied from 15 to 26. Sensitivity and specificity of the POMA ranged from 24-91 to 37-97, respectively.

Conclusion: Due to heterogeneity of the type of studies, participants, the definition of fall, and use of different versions of POMA, it was not possible to determine a specific cutoff point for POMA. In addition, using the same version and scoring method of POMA and controlling the significant potential confounders (eg, age, gender, and comorbidities) would provide better information about the predictive accuracy of POMA for falls in older adults.

Time-course investigation of postural sway variability: Does anxiety exacerbate the sensory reweighting impairment in chronic stroke survivors?

Although anxiety is one of the most prevalent psychological disorders in stroke survivors, its effect on sensory reweighting has not yet been fully studied. The aim of this work was to investigate how anticipation of collision avoidance events affects sensory reweighting in chronic stroke survivors with low and high levels of anxiety (LA-stroke and HA-stroke, respectively), as compared with healthy controls (HC), under the condition of perturbed proprioception. Eighteen LA-stroke and 18 HA-stroke survivors, as well as 18 gender- and age-matched HC, participated in this study. Postural sway variability (i.e. Root Mean Square (RMS) of the COP velocity) was measured for a duration of 180 s under two conditions: quiet standing and standing while predicting random virtual spheres to be avoided. Proprioceptive perturbation was simulated using bilateral Achilles tendon vibration at mid duration (60 s) for both conditions. The results showed that the HC were able to timely use visual anticipation to reduce the postural sway variability induced by tendon vibration. However, marked delay in using such anticipation was observed in stroke participants, especially in the HA-stroke group, as indicated by a significant decrease in the RMS of the COP velocity late in the vibration phase. This is the first study to consider the effect of anxiety while comparing sensory reweighting between stroke and healthy participants. The results indicated that chronic stroke survivors, particularly those with HA, could not efficiently use sensory reweighting to maintain balance in sensory conflicting conditions, which may subject them to loosing balance and/or falling. These findings are critical for future assessment and planning of rehabilitation interventions and balance in chronic stroke survivors.

The effect of early intervention of mirror visual feedback on pain, disability and motor function following hand reconstructive surgery: a randomized clinical trial

OBJECTIVE:

To determine the effect of mirror visual feedback (MVF) on disability, pain, and motor function on patients who underwent hand reconstructive surgery.

DESIGN:

Randomized, single-blinded controlled trial.

SETTING:

Rehabilitation center.

SUBJECTS:

A total of 40 patients who were randomly assigned into the intervention group ( n = 20) and control group ( n = 20) participated in this study.

INTERVENTIONS:

The rehabilitation sessions took place twice a week for eight weeks. The control group received traditional rehabilitation for 75 minutes. While the intervention group performed MVF and traditional rehabilitation for 30 and 45 minutes, respectively.

MEASURES:

Pain and disability of the hand were assessed with McGill pain questionnaire and Disability of Arm, Shoulder, and Hand (DASH) scores. The range of joint motion was evaluated by Goniometer, and the strength of grip and pinch was evaluated by Dynamometer and Pinch gauge and dexterity evaluated by Minnesota Manual Muscle test.

RESULTS:

The results indicated that both traditional and MVF methods induced significant decreasing pain (Pain Rate Index: F = 68.48, P = 0.000; Number of Word Count: F = 70.96, P = 0.000), disability ( F = 50.08, P = 0.000) and increasing dexterity (placing test: F = 28.73, P = 0.000), and range of motion ( F = 33.16, P = 0.000). The results also showed that the positive effect of MVF on pain, disability, dexterity, and range of motion was significantly greater than that of controls ( P < 0.05), but there was no significant result in grip and lateral pinch strength between the intervention and control group ( P > 0.05).

CONCLUSION:

MVF, in conjunction with traditional rehabilitation programs, may lead to greater improvements in pain, disability, placing dexterity, and range of motion. But it seems not to be effective on pinch and grip power and turning dexterity.

Improvement of Upper Limb Motor Control and Function After Competitive and Noncompetitive Volleyball Exercises in Chronic Stroke Survivors: A Randomized Clinical Trial

OBJECTIVES

To investigate the effects of competitive and noncompetitive volleyball exercises on the functional performance and motor control of the upper limbs in chronic stroke survivors.

DESIGN

Randomized clinical trial.

SETTING

Outpatient rehabilitation center.

PARTICIPANTS

Chronic stroke survivors (N=48).

INTERVENTIONS

Participants were randomly assigned to competitive (n=16) or noncompetitive (n=16) volleyball exercise groups (60min/d volleyball exercise+30min/d traditional rehabilitation, 3d/wk for 7wk) and control group (n=16).

MAIN OUTCOME MEASURES

Reach and grasp motor control measures were evaluated through kinematic analysis. Functional outcomes were assessed via Motor Activity Log, Wolf Motor Function Test (WMFT), Box and Block Test, and Wrist Position Sense Test.

RESULTS

Significant improvement of functional performance was observed in both competitive (P<.0001) and noncompetitive volleyball exercise groups (P<.01), but not in the control group (P>.05), with the exception of WMFT score. Volleyball training, in general, resulted in more efficient spatiotemporal control of reach and grasp functions, as well as less dependence on feedback control as compared to the control group. Moreover, the competitive volleyball exercise group exhibited greater improvement in both functional performance and motor control levels.

CONCLUSIONS

Volleyball team exercises, especially in a competitive format, resulted in enhancing the efficacy of the preprogramming and execution of reach and grasp movements, as well as a shift from feedback to feedforward control of the affected upper limb in chronic stroke survivors. This may well be a potential underlying mechanism for improving functional performance.
