Q

What is GMPM?

A

The GMPM is an observational instrument used to evaluate gross motor performance (i.e., quality of movement) in children with cerebral palsy. The instrument’s primary purpose is to evaluate change over time in specific qualitative features or attributes of gross motor behaviour. The measure was found to be responsive to change over time.

Q

What is the GMFM

A

The Gross Motor Function Measure (GMFM) is an assessment tool designed and evaluated to measure changes in gross motor function over time or with intervention in children with cerebral palsy. It was first developed in the late 1980s for use in both clinical and research settings and has evolved through advanced analytic techniques and in response to requests for more efficient testing. The GMFM user’s manual is available for purchase at the Mac Keith Press website.

Q

How does baclofen work?

A

Chemically, baclofen is a derivative of the neurotransmitter γ-aminobutyric acid (GABA). It is believed to work by activating (or agonizing) GABA receptors, specifically the GABAB receptors. Its beneficial effects in spasticity result from its actions in the brain and spinal cord

A

The PEDI (Pediatric Evaluation of Disability Inventory), is an interview-based assessment that can be used to monitor the self-care, mobility and social abilities of a person with cerebral palsy.

There are two versions of this assessment widely used in clinical practice today
