The recent increase in scientific activity related to traumatic brain injury (TBI)—and in particular, mild TBI and concussion—parallels the growth of public interest in the field. As the international scientific community aligns itself to better diagnose, treat, and manage this injury ( 79 ), which

The purpose of the paper is to provide specialists with theoretical frameworks that can be used to guide the creation of physical activity interventions as well as facilitating participation for people with traumatic brain injuries. Two frameworks for examining the physical activity motivation of people with brain injuries are presented. The theories include Bandura’s (1986) self-efficacy theory and Harter’s (1987) mediational model of self-worth. The constructs within both theories are explained and then applied to people with brain injuries. Suggestions for practitioners are also provided about how to manipulate the physical activity environment to promote physical activity participation.

The aim of the study was to provide evidence for the validity and reliability of the Physical Activity Affect Scale (PAAS; Lox, Jackson, Tuholski, Wasley, & Treasure, 2000) as a measure of exercise induced affect for adults with brain injuries. The PAAS is a 12-item measure of feeling states based on Russell’s (1980) conceptualization of affect. A confirmatory factor analysis was conducted on data from 193 participants with brain injuries who completed the PAAS following a single bout of exercise. Results identified four dimensions of affect (positive affect, negative affect, tranquility, and fatigue). Findings provide evidence for the validity and reliability of the PAAS as a measure of exercise induced affect for adults with brain injuries.

The purpose was to examine psychosocial factors that influence the physical activity behaviors of adults with brain injuries. Two differing models, based on Harter’s model of self-worth, were proposed to examine the relationship between perceived competence, social support, physical self-worth, affect, and motivation. Adults numbering 384 with brain injuries completed a series of questionnaires measuring each psychosocial variable. The structural analysis indicated a nonsignificant chi squared value and good fit indices for model two which included affect as the mediating variable. Findings indicate that affect is critical in shaping the physical activity cognitions and behaviors of adults with brain injuries. Suggestions are made on practical ways to enhance affect and subsequently physical activity participation.

Individuals with severe physical and psychomotor modifications after a brain injury need measures of motor training beyond the usual physiotherapy. The effects of an intensive mobility training in the phase of late rehabilitation are reported in two case studies. The coordinative and conditional progresses were controlled by the methods of photographic anthropometry, light-track registration, and bicycle ergometry. Improvements were found in posture and dynamic endurance in correlation with the generally improving motor control. Tests of everyday relevant movements revealed qualitative progresses in the sense of increased motor precision and economy.

The study consisted of (a) assessing the validity and reliability of the Social Influence Scale (SIS) for adults with brain injuries and (b) examining the types and sources of social influence and demographic variables that affect participants’ physical activity behaviors. Three confirmatory factor analyses, intraclass correlations, and a repeated measures MANOVA were completed on responses from 402 adults with brain injuries. Results provide evidence of the validity and reliability of the SIS, and post hoc analyses revealed that participants reported receiving different types of social influence from family, friends, and caregivers. Findings have implications for specialists and suggestions are provided on ways to enhance the physical activity participation of adults with brain injuries.

Traumatic brain injury (TBI) is a significant public health issue due to the incidence, complexity, and cost associated with treatment. The purpose of this study was to determine physical activity (PA) knowledge, attitudes, intentions, and barriers among individuals with a TBI undergoing outpatient rehabilitation. Seventeen participants completed a series of group interviews regarding their PA needs. A qualitative research design was adopted and trustworthiness was established through investigator triangulation of data. A cross-case analysis was completed to identify themes and conceptual patterns. The main themes identified were (a) an inability to differentiate between PA and physical therapy, (b) a limited knowledge of PA health benefits and the relationship to rehabilitation, and (c) an interest in participating in a PA based health promotion program. Future interventions should educate individuals about PA, the associated health benefits, and the role PA plays in the rehabilitation process.

Background:

The purpose of this article is to describe the development and evaluation of a task-oriented group exercise program, delivered through a municipal recreation program, for community-dwelling people with neurological conditions.

Methods:

Physical therapists (PTs) at a rehabilitation hospital partnered with a municipal recreation provider to develop and evaluate a 12-week exercise program for people with stroke, acquired brain injury, and multiple sclerosis at 2 community centers. Fitness instructors who were trained and supported by PTs taught 1-hour exercise classes twice a week. In a program evaluation of the safety, feasibility and effects of the program, standardized measures of physical function were administered before and after the program.

Results:

Fourteen individuals (mean age: 63 years) participated and attended 92% of exercise classes, on average. Two minor adverse events occurred during 293 attendances. Improvement in mean score on all measures was observed. In people with stroke, a statistically significant improvement in mean Berg Balance Scale (mean ± SD change = 3 ± 2 points, P = .016, n = 7) and 6-minute walk test scores (change = 26 ± 26 m, P = .017, n = 9) was observed.

Conclusions:

This model of exercise delivery provides people with neurological conditions with access to a safe, feasible and potentially beneficial exercise program in the community.
