Motor impairment outcome measures in neuro-physiotherapy
Motor impairment measures quantify deficits in strength, selective movement, tone, coordination, dexterity, and motor control. They are different from activity measures such as the Barthel Index or Timed Up and Go, though both are often recorded in rehabilitation.
| Measure | Main motor domain | Typical population / use | Score or key feature |
|---|---|---|---|
| Fugl-Meyer Assessment (FMA) | Motor recovery, reflex activity, synergy patterns, isolated movement, coordination | Stroke with hemiparesis | Motor section: 0-100: upper limb 66, lower limb 34. A core post-stroke impairment measure. |
| Chedoke-McMaster Stroke Assessment (CMSA) | Stage of motor recovery and postural control | Stroke | Classifies arm, hand, leg and foot recovery into 7 stages, from flaccidity to normal movement. |
| Stroke Rehabilitation Assessment of Movement (STREAM) | Voluntary limb movement and basic mobility | Acute or subacute stroke | 30 items, covering upper limb, lower limb, and basic mobility. |
| Motor Assessment Scale (MAS) | Functional motor performance after stroke | Stroke | Nine performance items, including rolling, sitting balance, walking and hand movements. |
| Motricity Index (MI) | Voluntary strength in affected limbs | Stroke and other unilateral UMN lesions | Rates strength of 3 upper-limb and 3 lower-limb movements. Quick bedside assessment. |
| Medical Research Council (MRC) muscle power grading | Individual muscle strength | Any neurological condition | 0-5 grade for each tested muscle or muscle group. |
| MRC Sum Score | Global limb strength | ICU-acquired weakness, Guillain-Barré syndrome, critical illness | Six bilateral muscle groups, total 0-60. |
| Action Research Arm Test (ARAT) | Upper-limb function, grasp, grip, pinch, gross movement | Stroke, brain injury | 0-57. Particularly useful when arm and hand activity is a goal. |
| Wolf Motor Function Test (WMFT) | Timed upper-limb task performance and functional ability | Stroke | Timed tasks plus functional ability rating. Often used in constraint-induced movement therapy. |
| Box and Block Test | Gross manual dexterity | Stroke, MS, cerebral palsy, traumatic brain injury | Number of blocks transferred in 60 seconds. |
| Nine-Hole Peg Test (9HPT) | Fine finger dexterity | Multiple sclerosis, stroke, Parkinson disease | Time taken to place and remove nine pegs. |
| Jebsen-Taylor Hand Function Test | Functional hand use | Stroke and hand neurological conditions | Timed simulated daily tasks such as writing, lifting objects, and feeding. |
| Finger Tapping Test | Simple motor speed and lateralised fine motor impairment | Parkinson disease, brain injury, other neurological disorders | Number of taps in a set time interval. |
| Modified Ashworth Scale (MAS) | Resistance to passive movement, often recorded as spasticity | Stroke, SCI, cerebral palsy, MS | Not a direct measure of voluntary motor performance. Interpret with caution. |
| Tardieu Scale / Modified Tardieu Scale | Spasticity and dynamic muscle overactivity | CP, stroke, SCI | Uses velocity-dependent responses and joint angles; can distinguish neural overactivity from fixed contracture better than MAS. |
| Scale for the Assessment and Rating of Ataxia (SARA) | Ataxia, coordination and balance | Cerebellar disorders | 0-40, including gait, stance, sitting, speech, limb coordination. |
| Unified Parkinson’s Disease Rating Scale, Part III (MDS-UPDRS III) | Parkinsonian motor signs | Parkinson disease | Assesses bradykinesia, rigidity, tremor, gait and postural stability. |
| Gross Motor Function Measure (GMFM-66/88) | Gross motor ability | Cerebral palsy, especially children | Lying/rolling, sitting, crawling/kneeling, standing, walking/running/jumping. |
| Hammersmith Functional Motor Scale | Motor performance in neuromuscular disease | Spinal muscular atrophy | Disease-specific measure, selected according to functional level. |
Common choices by condition
- Stroke: FMA + CMSA or STREAM; add ARAT/Box and Block/9HPT for upper limb and dexterity.
- Parkinson disease: MDS-UPDRS III; add gait and balance measures if relevant.
- Multiple sclerosis: 9HPT for upper-limb dexterity, MRC grading or dynamometry for strength, plus condition-specific walking measures.
- Cerebral palsy: GMFM-66/88; Modified Tardieu Scale when spasticity affects movement.
- Spinal cord injury: International Standards for Neurological Classification of SCI (ISNCSCI/ASIA) motor score, MRC grading, and measures matched to transfer, wheelchair, hand or walking goals.
- Cerebellar disease: SARA, with coordination tests such as finger-nose and heel-shin testing.
Practical selection
Use at least one measure that matches the patient’s chief impairment:
- Selective motor control / hemiplegic recovery: FMA or CMSA
- Strength: MRC grading, MRC Sum Score, or dynamometry
- Upper-limb reach, grasp and dexterity: ARAT, WMFT, Box and Block, 9HPT
- Tone/spasticity affecting movement: Modified Tardieu Scale, with MAS as a supplementary measure
- Coordination/ataxia: SARA
- Paediatric gross motor skill: GMFM
The Fugl-Meyer Assessment is particularly well supported for quantifying post-stroke motor impairment and has very high reported intra-rater and inter-rater reliability in the RehabMeasures summary. A useful clinical battery should not rely only on an impairment scale: pair it with an activity measure such as gait speed, 5-times sit-to-stand, TUG, Berg Balance Scale, or Barthel Index when those domains are relevant.
