Stroke Impact Scale (SIS): A Comprehensive Overview
Purpose and Design of the SIS
The Stroke Impact Scale (SIS) aims to evaluate how stroke has impacted an individual’s health and life, capturing the patient’s perspective on their recovery journey. Designed as a self-report questionnaire, the SIS assesses various domains affected by stroke. Its design incorporates items rated on a Likert scale, reflecting the difficulty experienced in different activities. The SIS measures aspects important to stroke patients and experts, aiding in comprehensive stroke rehabilitation planning.
Stroke Impact Scale (SIS): A Comprehensive Overview
SIS as a Self-Report Health Status Measure
As a self-report health status measure, the Stroke Impact Scale (SIS) directly captures the individual’s experience post-stroke. This approach is crucial, as it reflects the patient’s perception of their functional abilities, emotional well-being, and overall quality of life. By allowing patients to report their challenges and successes, the SIS provides valuable insights that might be missed by clinician-observed assessments alone, ensuring a holistic view of the stroke’s impact.
The Stroke Impact Scale (SIS) assesses multiple domains impacted by stroke. These include strength, hand function, activities of daily living, mobility, communication, emotion, memory, and thinking. These domains offer a comprehensive view of post-stroke health.
Strength
Within the Stroke Impact Scale (SIS), the strength domain evaluates the physical power and effort a person can exert post-stroke. This section of the SIS helps determine the degree to which a stroke has affected an individual’s muscle strength. It assesses the impact of stroke on activities requiring physical exertion. The SIS also measures strength in different parts of the body. This is very important for monitoring recovery and rehabilitation progress.
Hand Function
The hand function domain in the Stroke Impact Scale (SIS) specifically addresses the dexterity and functionality of the affected hand and arm following a stroke. This section evaluates the person’s ability to perform tasks requiring fine motor skills. The hand function measures the impact of stroke on activities like writing, grasping objects, and manipulating small items. It is essential for assessing independence in daily living. It also provides insight into the effectiveness of rehabilitation interventions.
Activities of Daily Living/Instrumental Activities of Daily Living (ADL/IADL)
This domain of the Stroke Impact Scale (SIS) examines the impact of stroke on a person’s ability to perform essential Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL). ADLs encompass basic self-care tasks such as bathing, dressing, and eating. IADLs involve more complex activities like managing finances, preparing meals, and using transportation. Assessing these areas provides a comprehensive understanding of a patient’s independence and need for assistance.
Mobility
The Mobility domain within the Stroke Impact Scale (SIS) focuses on assessing a stroke survivor’s ability to move around and navigate their environment. This includes evaluating their capacity to walk, climb stairs, maintain balance, and transfer between different positions, like sitting and standing. Limitations in mobility are common after stroke and significantly impact a person’s independence, participation in daily activities, and overall quality of life. The SIS mobility domain helps identify specific challenges and track progress during rehabilitation.
Communication
The Communication domain of the Stroke Impact Scale (SIS) evaluates a stroke survivor’s ability to express themselves and understand others. This includes assessing their speech, language comprehension, reading, and writing skills. Communication difficulties are common after stroke (aphasia), impacting social interaction, emotional well-being, and participation in daily life. The SIS communication domain helps to identify the specific communication impairments a patient experiences, which helps clinicians to develop appropriate rehabilitation strategies. The assessment also provides a baseline to monitor progress throughout recovery.
Emotion
The Emotion domain of the Stroke Impact Scale (SIS) addresses the emotional and psychological impact of stroke on an individual’s well-being. It assesses feelings of anxiety, depression, anger, and overall emotional control. Post-stroke depression significantly affects quality of life and rehabilitation outcomes. The SIS emotion domain helps to identify and quantify these emotional challenges. This enables healthcare professionals to provide appropriate support and interventions, such as counseling, medication, or other therapies. Addressing emotional health is crucial for improving overall recovery and quality of life after stroke.
Domains Assessed by the Stroke Impact Scale
Memory and Thinking
The Memory and Thinking domain of the Stroke Impact Scale (SIS) evaluates cognitive functions affected by stroke. This encompasses areas like memory recall, attention span, problem-solving abilities, and overall cognitive processing speed. Cognitive impairments post-stroke can significantly impact daily functioning and independence. The SIS domain helps to quantify the severity of these cognitive deficits from the patient’s perspective. This information is vital for tailoring cognitive rehabilitation strategies. Effective cognitive interventions can improve memory, attention, and executive functions. This ultimately enhances the patient’s ability to participate in daily activities and improve their quality of life.

Its sensitivity to change is crucial for evaluating treatment effectiveness and monitoring patient recovery. The SIS’s responsiveness supports its application in longitudinal studies and clinical trials, as well as routine clinical practice. This makes it a valuable tool for stroke management.
Minimal Detectable Change (MDC)
The Minimal Detectable Change (MDC) of the Stroke Impact Scale (SIS) helps clinicians determine the smallest change in score that represents a real improvement, beyond measurement error. MDC values aid in interpreting individual patient progress.
Minimal Detectable Change (MDC)
Establishing the Minimal Detectable Change (MDC) for the Stroke Impact Scale (SIS) is crucial for interpreting changes in patient scores following stroke. The MDC represents the smallest amount of change that reflects a true difference, exceeding measurement error. Studies aim to determine the MDC for physical domains of the SIS, helping clinicians to identify genuine improvements in patients’ physical functioning post-stroke and evaluate the effectiveness of rehabilitation interventions with greater accuracy, ensuring appropriate and tailored care plans. This enhances outcome interpretation and clinical decision-making.
Clinical Significance of the Stroke Impact Scale
Clinically Important Differences (CIDs)
Determining the Clinically Important Differences (CIDs) of the Stroke Impact Scale (SIS) is essential for gauging the practical significance of observed changes after stroke. CIDs represent the minimum amount of change in SIS scores that patients perceive as meaningful improvements in their daily lives. Research aims to establish CIDs for the SIS, helping clinicians and researchers understand whether interventions lead to noticeable benefits. By identifying CIDs, healthcare professionals can better assess treatment effectiveness, prioritize patient-centered care, and interpret research findings in a context that truly matters to stroke survivors and their overall well-being.
