Arithmetic operations without symbols are unimpaired in adults with math anxiety.

This study characterises a previously unstudied facet of a major causal model of math anxiety. The model posits that impaired "basic number abilities" can lead to math anxiety, but what constitutes a basic number ability remains underdefined. Previous work has raised the idea that our perceptual ability to represent quantities approximately without using symbols constitutes one of the basic number abilities. Indeed, several recent studies tested how participants with math anxiety estimate and compare non-symbolic quantities. However, little is known about how participants with math anxiety perform arithmetic operations (addition and subtraction) on non-symbolic quantities. This is an important question because poor arithmetic performance on symbolic numbers is one of the primary signatures of high math anxiety. To test the question, we recruited 92 participants and asked them to complete a math anxiety survey, two measures of working memory, a timed symbolic arithmetic test, and a non-symbolic "approximate arithmetic" task. We hypothesised that if impaired ability to perform operations was a potential causal factor to math anxiety, we should see relationships between math anxiety and both symbolic and approximate arithmetic. However, if math anxiety relates to precise or symbolic representation, only a relationship between math anxiety and symbolic arithmetic should appear. Our results show no relationship between math anxiety and the ability to perform operations with approximate quantities, suggesting that difficulties performing perceptually based arithmetic operations do not constitute a basic number ability linked to math anxiety.

Exploring the use of educational materials for increasing participation in a stretching program: a quality improvement project in people with motor neuron disease.

BACKGROUND: Decreased range of motion is a common secondary complication of motor neuron disease (MND) that can contribute to functional decline and decreased participation in daily activities. AIM: The purpose of this study was to develop and assess the effectiveness of educational brochures and videos aimed at improving knowledge regarding the importance of a regular stretching program. DESIGN: This was a quality improvement (QI) project. SETTING: Participants were seen in an outpatient multidisciplinary neuromuscular clinic. POPULATION: Individuals with motor neuron disease were invited to participate in this QI study. METHODS: Individuals were asked to complete surveys asking questions regarding current stretching program, pain levels, and knowledge of benefits of stretching before and after receiving the stretching brochures or videos. RESULTS: A total of 53 participants completed the pre-intervention survey, 28 in the brochure group and 25 in the video group. Of those, 86% and 88% completed the post-intervention survey in the brochure and video groups, respectively. The video group increased stretching frequency significantly more than the brochure group (2.04 and 0.62 days/week respectively, P=0.004). Significantly more participants in the video group reported usage of stretches from the educational materials on a regular basis (54% for brochure group and 86% for video group, P=0.024). CONCLUSIONS: Educational brochures and videos are two different strategies to improve knowledge of benefits of stretching for individuals with MND. Both groups increased frequency of stretching. Videos may be better able to improve frequency of stretching when compared to brochures. CLINICAL REHABILITATION IMPACT: The brochures and videos developed for this study can be used by clinicians treating individuals with MND. By improving knowledge regarding the benefits of stretching, individuals with MND may choose to prioritize stretching as a part of their routine. This in turn may help to prevent or address potential joint or muscle length issues or assist patients to incorporate preventative measures into their treatment plans.

Sensory Processing Difficulties in Functional Neurological Disorder: A Possible Predisposing Vulnerability?

BACKGROUND: Functional neurological disorder (FND) is a prevalent neuropsychiatric condition characterized by sensorimotor difficulties. Patients with FND at times report that sensory experiences trigger and/or exacerbate their symptoms. Sensory processing difficulties are also commonly reported in other psychiatric disorders frequently comorbid in FND, suggesting that contextualizing sensory profiles in FND within a biopsychosocial model may be clinically relevant. OBJECTIVE: To address this literature gap, we conducted a retrospective cohort study to examine sensory processing patterns and their relationship to other neuropsychiatric characteristics in patients with FND. METHODS: A retrospective chart review design was used to investigate sensory processing patterns, established with the Adolescent/Adult Sensory Profile self-report questionnaire, in 44 patients with FND. Univariate analyses of cross-sectional screening tests followed by multivariate linear regression analyses were performed to identify clinical factors associated with sensory processing scores in the FND cohort. RESULTS: Compared to normative data, most patients with FND reported sensory processing tendencies toward low registration, sensory sensitivity, and sensation avoiding. In multivariate regression analyses, the presence of a lifetime anxiety disorder independently predicted elevated low registration scores, while female gender and number of current medications independently predicted increased sensory sensitivity scores. In uncorrected univariate analyses only, individuals with psychogenic nonepileptic seizures were more likely to report increased sensory sensitivity and elevated low registration. CONCLUSION: These preliminary findings support sensory processing difficulties in some patients with FND. Prospective and large sample size studies are needed to investigate relationships between sensory processing profiles and neuropsychiatric comorbidities, FND subtypes, and treatment outcomes.
