Objective[edit | edit source]
The Test of Infant Motor Performance (TIMP) is a motor outcome measure to assess posture and selective control of movement in infants for functional performance in daily life. The TIMP was developed to
- identify infants with delayed motor development
- precisely track typically developing infants
- evaluate and develop intervention goals for infants with delays
- educate parents on infant motor development[1][2]
It is used by physical and occupational therapists to identify infants with motor delay between 34 weeks post-conceptional to 4 months post-term. In addition the TIMP is used to plan an intervention program and document change in motor performance over time. The TIMP can be used both in special care nursery settings and in early intervention programs, thus facilitating communication among caregivers in different settings.
Components[edit | edit source]
TIMP consists of reviewing a total of 42 items:
- 13 items are observed during a period of spontaneous activity
- head orientation in the midline,
- ballistic movements of the limb
- 29 items are elicited
Scoring: Correct scoring is explained during workshops.
Environment for Testing: The TIMP can be used both in special care nursery settings and in early intervention programs. It can be carried out at an outpatient basis and in the NICU but a regular follow up and documentation needs to be maintained.
Equipment and Materials Needed: Testing forms and pen, ball, cloth and rattle[4]
Examiner Qualifications: The test must be administered by those with experience in the TIMP attained by workshops.
Relevant Information[edit | edit source]
The increasing survival rate of infants with a complicated birth and perinatal history generated the need for a test of functional motor performance with the capability identifying children under four months of age with delayed development which could addressed with physical therapy. The first version of the test was developed by Girolami,[5] however it was too lengthy and time consuming to be followed regularly. As a result the short concise version was made by Suzann Campbell.
The Test of Infant Motor Performance (TIMP) is the current gold standard infant motor assessment, but rarely used by pediatricians during well-child visits due to lack of time and special training required. A short, standardized screening test administered to infants in the first months of life would target early intervention to those most at risk hence proving the importance of the test.
This test has been conducted more widely and regularly in the US but has started gaining momentum with the NDT trained therapists all over the world thanks to its positive results.
Reliability/ Validity[edit | edit source]
The usefulness of a tool in a clinical setting depends on how much the clinician can rely on the data and how stable the data is over time. A good tool will have strong reliability, validity, and will be responsive to change.
Reliability refers to how consistent the tool is at measuring your outcome of interest, and is it free of error.
Test–retest reliability of the TIMPSI was excellent with the intra-class coefficient of 0.99[6].
The test-retest reliability for 116 pairs of tests of r = .89 over 3 days; no significant difference between testers.
Standardization data: Diagnose motor developmental delay from 34 weeks post-conception age through 4 months post term based on age standards developed from a sample of 990 U.S. infants of all races/ethnicities.
Predictive/Discriminative: Predicts 12-month motor performance with sensitivity 92% and specificity 76% and preschool motor performance with sensitivity 72% and specificity 91% at 3 months of age.
Validity of an assessment is the degree to which it measures what it is supposed to measure.
In case of TIMP, its validity was measured by comparing it with Alberta Infant Motor scale (AIMS) and correlation between scores on the TIMP and the AIMS was highest for TIMP tests at 90 days and AIMS testing at 6 months (r=0.67, p=0.0001) concluding that TIMP can be used clinically to identify infants likely to benefit from intervention[7].
