Theoretical Framework Substantive reviews of the literature were completed. The literature pertaining to post-stroke mobility, gait speed, falls, and fear of falling were incorporated into the ICF model (see Figure 1-2). It was used to guide the research questions and analyses for these studies. In this study, the general health condition was "stroke." The type of stroke and severity of stroke are important aspects that may impact post-stroke mobility. Stroke related body function and body structure included sensory, cognitive, and motor impairments. Environmental factors included caregiver depression, burden, and coping. Personal factors included age, race, and cognition. These stroke related impairments and personal factors might be related to activity limitations; such as difficulties completing ADLs and IADLs, including walking, stair climbing, dressing, bathing, toileting, etc. Mobility is a construct of ADLs and is therefore considered an aspect of activity. Gait speed and fear of falling are each aspects of post-stroke mobility, and are therefore considered as activity. It is thought that losses in gait speed and the development of fear of falling adversely impact ADLs, IADLs, and social participation. Body function and structure impairments and especially activity limitations may restrict participation in society, thereby limiting role fulfillment at home, work, and within the social environment. All of these post-stroke changes may also influence caregiver burden, coping, depression. The current study was developed to specifically address the relationships between changes in gait speed and the development of fear of falling with ADLs, IADLs, participation, and depression. All aspects of the model may be affected by post-stroke mobility. Activity, participation, and environmental/personal factors must therefore be
