Modified Parkinson Activity Scale (MPAS)
Description
The Modified Parkinson Activity Scale (MPAS) is an instrument used to assess functional mobility in individuals with Parkinson’s disease. According to the provided source, the scale consists of 10 items and evaluates the effectiveness with which specific motor activities are performed.
The scale focuses on functional activities that are directly related to everyday mobility and allows the examiner to identify difficulties that may occur during their performance.
Purpose
The main purpose of the MPAS is the systematic assessment of movement effectiveness and functional mobility in individuals with Parkinson’s disease.
Its use allows difficulties in basic daily motor activities to be documented and may support the monitoring of a patient’s functional status.
Scale Structure
The MPAS includes 10 items, divided into four main categories:
Chair Transfers: assesses the individual’s ability to perform functional movements related to sitting down and standing up from a chair.
Gait Akinesia: concerns difficulties in initiating or performing walking movements associated with akinesia.
Bed Mobility: evaluates the patient’s ability to move and change position while in bed.
Bed Mobility with Blanket: assesses similar mobility tasks while adding the functional requirement of managing a blanket.
Scoring
The scale uses a scoring system ranging from 0 to 4.
According to the source, the maximum score of 4 corresponds to performance of the test without problems.
Lower scores therefore reflect greater difficulty in performing the corresponding motor activity.
Type of Instrument
The provided material classifies the MPAS as an observational and questionnaire-based instrument.
The primary functional domain assessed is mobility and movement.
Target Population
According to the source document, the scale may be used with:
adults and older adults.
Its main clinical application concerns individuals with Parkinson’s disease, as well as conditions involving the nervous system and sensory functions.
Statistical Analysis
The provided source does not describe specific statistical analysis procedures or psychometric indices.
Based on the structure of the scale, scores may be used to describe the degree of functional difficulty across specific activities and to monitor changes in mobility over time.
For more specialized analysis procedures, reference to the official version and corresponding publications is required.
Applications
The MPAS may be used in clinical and rehabilitation settings to assess functional mobility in patients with Parkinson’s disease.
Its structure allows observation of specific daily motor activities, including transfers, walking, and bed mobility.
It may also be used to compare functional status across different assessment time points and to monitor possible changes during therapeutic or rehabilitation interventions.
