The uptake and benefits of the Canadian Physical Activity Guidelines for Adults with Multiple Sclerosis (PAGs) have been validated, but there is limited understanding regarding the knowledge, needs, and preferences of people with multiple sclerosis (MS) for implementing the PAGs outside of clinical research. The authors conducted online, semistructured interviews with 40 persons with MS from across the United States seeking information on awareness of and potential approaches for increasing the uptake of the PAGs. They identified first impressions and potential approaches for increasing the uptake of the PAGs through inductive, semantic thematic analysis. Participants perceived the PAGs as a good introduction for structured exercise but desired more information on how to meet the PAGs. Participants further believed that modifying the PAGs for inclusivity and applying a multifaceted approach for dissemination and implementation may increase uptake of exercise behavior. Physical activity research in MS should include both analyzing the effects of exercise and the unique challenges faced by persons with MS in putting the PAGs into practice.

The goal of this study was to determine if emotional expressions at the end of swimmers’ 2016 Paralympic races varied according to medal won and if their race wins and losses were close or not close. Using FaceReader software, videos of 46 races of medal-winning Paralympic (M age = 24.6; SD = 5.4) swimmers’ faces (78 males and 60 females) from 22 countries were analyzed. Silver medalists were angrier and sadder than gold medalists and angrier and more disgusted than bronze medalists. Swimmers who swam slower than their 2015 best time were angrier than Paralympians who swam faster. Paralympians who finished lower than their 2015 world ranking had more neutral emotions and were less happy than Paralympians who finished higher. Gold medalists who narrowly defeated silver medalists were less happy and more fearful than gold medalists who won easily. Bronze medalists with close wins had fewer neutral emotions and were happier, less angry, and more surprised than bronze medalists with not-close wins. All medalists with close wins were more surprised than medalists with easier wins. Bronze medalists with close losses to silver medalists were happier and less angry than bronze medalists who lost more easily. Effect sizes ranged from d = 0.27 to 1.01. These results provide theoretical support to basic emotion theory and confirm the anecdotal observations that Paralympic competition generates wide-ranging and diverse emotions.

This study evaluated the validity of two wheelchair-mounted devices—the Cateye® and Wheeler—for monitoring wheelchair speed and distance traveled. Speed estimates were validated against a calibrated treadmill at speeds from 1.5 to 10 km/hr. Twenty-five wheelchair users completed a course of known distance comprising a sequence of everyday wheelchair activities. Speed estimate validity was very good (mean absolute percentage error ≤ 5%) for the Wheeleri at all speeds and for the Cateye at speeds >3 km/hr but not speeds <3 km/hr (mean absolute percentage error > 20%). Wheeleri distance estimates were good (mean absolute percentage error < 10%) for linear pushing activities and general maneuvering but poor for confined-space maneuvering. Cateye estimates were good for continuous linear propulsion but poor for discontinuous pushing and maneuvering (both general and confined space). Both devices provided valid estimates of speed and distance for typical wheelchair-based exercise activities. However, the Wheeleri provided more accurate estimates of speed and distance during typical everyday wheelchair activities.

In this study, the effects of an exercise therapy comprising yoga exercises and medial-thrust gait (YogaMT) on lower-extremity kinetics, pain, and function in patients with medial knee osteoarthritis were investigated. Fifty-nine patients were randomly allocated to three treatment groups: (a) the YogaMT group practiced yoga exercises and medial thrust gait, (b) the knee-strengthening group performed quadriceps- and hamstring-strengthening exercises, and (c) the treadmill walking group practiced normal treadmill walking in 12 supervised sessions. The adduction and flexion moments of the hip, knee, and ankle; pain intensity; and 2-min walking test were assessed before and after treatment and at 1-month follow-up. The YogaMT group experienced a significant reduction in knee adduction moment. All groups showed significant improvement in pain and function. The YogaMT may reduce medial knee load in patients with knee osteoarthritis in the short term. A larger clinical trial is required to investigate the long-term outcomes of this intervention.

The authors’ purpose was to examine the factors associated with penalty outcomes of male elite goalball. A total of 122 video-recorded matches from two Paralympic Games (i.e., 2012 and 2016) and the 2014 Goalball World Championship were assessed using notational analysis. Individual (n = 2), situational (n = 4), and performance variables (n = 7) were analyzed with good strength of agreement for intra- and interrater kappa index values. Their results showed that penalties play a very important role in the final score, composing around 25% of total goals in elite goalball matches. Winners were awarded on average with 62% of penalties and had 66% effectiveness compared with losers (31% and 53%) or drawers (8% and 52%). Based on the authors’ findings, penalty takers should direct their throws at specific target sectors on the court, which could increase their rate of success to over 80%.

Justifications for access to physical activity for people who experience disability tend to focus on the health benefits associated with a medical model of disability. The result is often programs that are segregated and impairment-focused, with limited access to integrated settings that are also potentially inclusive. In this instrumental case study, the authors engaged 20 participants with and without impairment from an adult integrated indoor cycling program to explore what contributed to meaningful and inclusive experiences in this setting. Data were generated through semistructured interviews and reflective notes. Thematic analysis led to three themes: (a) “just going to a spin class” (b) “seamless”? and (c) “deliberate community.” Using a relational ethics framework, the findings are discussed with regard to their potential to inform the development of integrated and inclusive physical activity programs, with emphasis on program structure and instructor reflexivity and training.

Fundamental motor skills (FMS) are an underlying mechanism driving physical activity behavior and promoting positive developmental trajectories for health. However, little is known about FMS of preschool-aged children with visual impairments (VI). The purpose of this study was to examine the FMS of preschool-aged children (N = 25) with (n = 10) and without (n = 15) VI as measured using the Test of Gross Motor Development-3. Children without VI performed significantly higher than their peers for locomotor (M = +11.87, p = .014, η2 = .31) and ball skills (M = +13.69, p < .001, η2 = .56). Regardless of the presence of a VI, many participants struggled with developing FMS, with the greatest disparity resting within ball skills. These findings help to clarify the FMS levels of preschool-aged children with VI. Thus, there is a need for both further inquiry and intervention for all children.

Youth with visual impairments are more likely to be overweight than peers without visual impairments and often struggle with their locomotor skills. Locomotor development can combat unhealthy body weight statuses by supporting physical activity behaviors. There are no longitudinal investigations concerning the locomotor skill and body mass index (BMI) developmental trajectories of youth with visual impairments. The purpose of this study was to examine the 3-year developmental trajectory of the locomotor skills and BMI of youth with visual impairments including differential effects of self-reported gender and degree of vision. Participants (N = 34, M age = 11.75 years, 47% female) showed severely delayed and arrested locomotor development with increases in BMI across 3 years regardless of self-reported gender or degree of vision. Participants failed to breech a proficiency barrier of motor competence to combat against increases in BMI across time. Additional longitudinal inquiries are needed.

The purpose of this single-masked randomized clinical trial was to examine whether nonleisure-time physical activity guidance (NLTPAG) improves physical activity levels in patients after minor ischemic stroke. Patients who had been hospitalized for minor ischemic stroke in an acute care hospital (National Health Institute Stroke Scale ≤ 5) were randomized to either an NLTPAG group (n = 17) or a leisure-time physical activity guidance group (n = 16). NLTPAG focused on reducing sedentary behavior and increasing the frequency of walking for shopping and household activities to improve physical activity levels in daily life. Physical activity levels significantly improved only in participants in the NLTPAG group (initial assessment: metabolic equivalents of task = 12.6; final assessment: metabolic equivalents of task = 14.8; p = .035, r = .51). These results suggest that NLTPAG may be effective for improving physical activity levels in patients after minor ischemic stroke.
