Transcranial direct current stimulation for chronic headaches, a randomized, controlled trial

Background and objectives

Chronic headaches are a frequent cause of pain and disability. The purpose of this randomized trial was to examine whether transcranial direct current stimulation (tDCS) applied to the primary motor cortex, reduces pain and increases daily function in individuals suffering from primary chronic headache.

Materials and methods

A prospective, randomized, controlled trial, where participants and assessors were blinded, investigated the effect of active tDCS vs. sham tDCS in chronic headache sufferers. Forty subjects between 18 and 70 years of age, with a diagnosis of primary chronic headache were randomized to either active tDCS or sham tDCS treatment groups. All patients received eight treatments over four consecutive weeks. Anodal stimulation (2 mA) directed at the primary motor cortex (M1), was applied for 30 min in the active tDCS group. Participants in the sham tDCS group received 30 s of M1 stimulation at the start and end of the 30-minute procedure; for the remaining 29 min, they did not receive any stimulation. Outcome measures based on data collected at baseline, after eight treatments and three months later included changes in daily function, pain levels, and medication.

Results

Significant improvements in both daily function and pain levels were observed in participants treated with active tDCS, compared to sham tDCS. Effects lasted up to 12 weeks post-treatment. Medication use remained unchanged in both groups throughout the trial with no serious adverse effects reported.

Conclusion

These results suggest that tDCS has the potential to improve daily function and reduce pain in patients suffering from chronic headaches. Larger randomized, controlled trials are needed to confirm these findings.

Trial registration

The study was approved by the local ethics committee (2018/2514) and by the Norwegian Centre for Research Data (54483).

Daily Functional Characteristics and Health Among Older Adults During COVID-19: A Structural Equation Modeling Approach

Within a few years, 1 in 6 people will be aged 60 years or older. Extreme situations, such as the COVID-19 crisis, constitute a challenge to older adults. However, the literature on the daily functional characteristics of older adults in the past and during the COVID-19 crisis and their relationships to their physical and mental health is scarce. This study aimed to examine the past and present daily functional factors associated with physical and mental health in older adults. Using an online platform, 204 Israelis aged 60 years and older reported their physical health symptoms and anxiety levels. They completed questionnaires about past (negative life events and childhood daily functional self-actualization) and present (adulthood daily functional self-actualization, functional cognition and sleep quality) factors. Structural equation modeling revealed correlations between functional cognition and childhood daily functional self-actualization (β = -.18) and anxiety (β = .15); adulthood daily functional self-actualization and past negative life events (β = -.18), anxiety (β = -.50), and physical symptoms (β = -16); and sleep quality and past childhood daily functional self-actualization (β = -.19), negative life events (β = .22), anxiety (β = .18), and physical symptoms (β = .40). These findings shed light on potential functional factors for older adults' health, indicating that these functional factors play a vital role in reducing health problems in later life.

Relationships between motor skills and executive functions in developmental coordination disorder (DCD): A systematic review

BACKGROUND

Individuals with developmental coordination disorder (DCD) experience motor skill and executive function (EF) difficulties that challenge their daily activities.

AIM/OBJECTIVE

This systematic review aims to provide an in-depth analysis of the relationships between motor skills and EFs in studies among individuals with DCD.

MATERIAL AND METHODS

We conducted a systematic search of eight electronic databases for articles (published 1994-2021) reporting on quantitative studies that estimated relationships between motor skills and EFs when assessing children, adolescents and adults with DCD. Motor skills and EFs were assessed via reliable and validated assessment tools. Two reviewers independently screened the articles. We evaluated the quality of the selected articles according to EPHPP guidelines and the methodological quality of the assessments from these studies using the COSMIN checklist and reported results following the PRISMA-P checklist. This systematic review was registered in PROSPERO (CRD42019124578).

RESULTS

A total of 30,808 articles were screened. Eleven articles met the inclusion criteria and were reviewed. Findings from nine studies demonstrated weak to strong correlations between aspects of motor skills and EFs.

CONCLUSIONS AND SIGNIFICANCE

Limited evidence supports the relationships between motor skills and EFs among individuals with DCD. Occupational therapists should consider the possibility of this relationship and give more consideration to these components when planning intervention for individuals with DCD.

The role of sensory processing difficulties, cognitive impairment, and disease severity in predicting functional behavior among patients with multiple sclerosis

PURPOSE

To compare sensory processing and functional behavior abilities between participants with multiple sclerosis (MS), with and without cognitive impairments, and healthy controls, and to examine the role disease severity, cognitive impairment, and sensory processing have in predicting the functional behavior of persons with MS.

METHODS

Sixty-one participants with MS were enrolled in this study, 43 with cognitive impairments and 18 without (based on the Brief International Cognitive Assessment for MS composite z-score), and 36 healthy controls. Participants were between the ages 23 and 63 and asked to complete the Adolescent/Adult Sensory Profile, Functional Behavior Profile, and MS Functional Composite.

RESULTS

Both MS groups showed sensory processing difficulties with lower ability to register sensory input and greater sensory sensitivity and avoidance versus healthy controls. Among both MS groups, sensory processing difficulties correlated with greater disease severity and poor functional behavior in daily life. The significant predictors of functional behavior in daily life were a lower ability to register sensory input and greater sensory avoidance.

CONCLUSIONS

Persons with MS have sensory processing difficulties regardless of their cognitive abilities, which negatively affect their functional behavior. Research and practice should further explore the role of sensory processing as expressed in daily scenarios for persons with MS and consider the functional impacts of this study in order to optimize daily life experiences for patients.Implications for rehabilitationSensory processing difficulties in multiple sclerosis (MS) are mainly expressed in poor ability to register and modulate sensory input from daily environment, regardless of patients' cognitive status.Sensory processing difficulties in MS may affect patients' ability to perform activities of daily living.Sensory processing difficulties in MS should be evaluated using objective measures (electrophysiology tools) as well as self-reports that reflect patients' difficulties in real life context.Intervention programs in MS should refer to sensory processing difficulties, to their correlation with disease severity, cognitive status and to their impacts on people's daily function.

A Survey of Patient and Partner Outcome and Treatment Preferences in Mild Cognitive Impairment

BACKGROUND

The patient-centered movement in health care is increasing efforts to design studies and interventions that address the outcomes that matter most to patients and their families. Research has not adequately addressed Alzheimer's disease patient and caregiver preferences.

OBJECTIVE

To survey the outcome and treatment preferences of patients and caregivers who had completed a multicomponent behavioral intervention for mild cognitive impairment (MCI).

METHODS

Extending prior work, we conducted an online survey regarding outcome and intervention preferences. Participants were patients with MCI and partners who completed the HABIT Healthy Action to Benefit Independence & Thinking ® program.

RESULTS

Both patient and partner respondents ranked patient quality of life as the highest priority, followed by patient self-efficacy, functional status, patient mood, and patient memory performance. Distressing behaviors and caregiver outcomes (burden, mood, and self-efficacy) had low rankings. Regarding the importance of HABIT ® program components, memory compensation training was ranked highest and wellness education lowest by all groups.

CONCLUSION

Additional research should compare patient preference for patient reported outcomes, traditional neuropsychological and clinician outcomes, and modern biomarker outcomes.

The effects of disease-related symptoms on daily function in Wolfram Syndrome

OBJECTIVE:

To investigate daily function among individuals with Wolfram Syndrome (WFS) and examine whether any limitations are related to disease-related symptoms.

METHODS:

WFS (n = 31), Type 1 diabetic (T1DM; n = 25), and healthy control (HC; n = 29) participants completed the Pediatric Quality of Life Questionnaire (PEDSQL) Self and Parent Report. PEDSQL domain scores were compared among these groups and between WFS patients with and without specific disease-related symptoms. Relationships between PEDSQL scores and symptom severity as assessed by the Wolfram Unified Rating Scale (WURS) Physical Scale were also examined.

RESULTS:

Across most domains, the WFS group had lower PEDSQL Self and Parent Report scores than the T1DM and HC groups. WFS participants with urinary, sleep, and temperature regulation problems had lower PEDSQL scores than those without. The WURS Physical Scale correlated with Self and Parent Report PEDSQL domains. WFS group Self and Parent Reports correlated with each other.

CONCLUSIONS:

The WFS group reported lower daily function compared to T1DM and HC groups. Within WFS, worse symptom severity and the specific symptoms of sleep, temperature regulation, and urinary problems were associated with poorer daily function. These findings provide rationale for an increased emphasis on identifying, treating and understanding these less well-known symptoms of WFS.

Life With HIV: Insights from HIV-infected Women in Cameroon, Central Africa

Women in Cameroon are disproportionately burdened by HIV illness. Understanding the impact HIV has on women is essential for developing interventions to enhance their quality of life. Our aim was to explore and provide an in-depth understanding of the daily experiences of a sample of women living with HIV in Cameroon. Qualitative semi-structured in-depth interviews were conducted with women (N = 30) from the northwest region of Cameroon who self-reported being infected with HIV. Participants shared that they had multiple challenges in their daily experiences living with HIV. The themes that emerged included: (a) receiving an HIV diagnosis is traumatic, (b) living with HIV is a constant struggle, (c) limited resources and support cause problems, and (d) stigma and powerlessness exacerbate the impact of HIV. We provide insight into the daily experiences of HIV-infected women in Cameroon. Implications for improving health care and social services to women living with HIV in Cameroon are suggested.
