Description of the Questionnaire

The Modified Postural Assessment Scale for Stroke (mPASS) is a balance assessment tool consisting of 12 items that evaluate an individual’s ability to maintain and transition between positions during both static and dynamic activities. Static activities include sitting posture, standing posture, and standing on the affected or unaffected leg, while dynamic activities involve movements such as transitioning from supine to side-lying, from sitting to standing, and bending to pick up an object from the floor. The mPASS is a modified version of the original Postural Assessment Scale for Stroke (PASS), and while it shares similarities with the Berg Balance Scale (BBS), it differs by assessing the affected and unaffected sides separately and by including transfers from and to lying positions. This makes it suitable for patients with a low functional level. The modified version includes small but essential adjustments aimed at clarifying the execution of the test items.

Data Analysis and Use

Each of the 12 items is scored on a 4-point scale. The total score reflects the patient’s balance and functionality and is used to track progress during rehabilitation, design personalized therapeutic interventions, and assess the need for supportive aids or assistance in daily living. Data can be analyzed both as a total score and separately by static and dynamic activities, offering a detailed picture of the individual’s capabilities.

Purpose

The main goal of the mPASS is the objective evaluation of balance ability in individuals who have suffered a stroke. The tool is used to monitor the progression of mobility, particularly in the early stages of rehabilitation, and it significantly contributes to tailoring the therapeutic plan based on the patient’s needs and abilities.

Scoring

Each task is scored using a four-point scale. A score of 0 indicates the task cannot be performed, 1 indicates that considerable assistance is required, 2 corresponds to performance with minimal help or supervision, and 3 indicates independent and safe execution. The maximum total score is 36 points, reflecting the patient’s level of autonomy and balance, and providing a clear indicator of rehabilitation progress.
