Summary
The High-Level Mobility Assessment Tool (HiMAT) reliably measures high-level mobility in individuals with traumatic brain injury (TBI). This new scale demonstrates excellent interrater reliability, retest reliability, and internal consistency.
Area of Science:
- Rehabilitation Medicine
- Neuroscience
- Physical Therapy
Background:
- High-level mobility assessment is crucial for individuals with traumatic brain injury (TBI).
- Existing assessment scales often lack specific measures for high-level mobility in TBI populations.
- The High-Level Mobility Assessment Tool (HiMAT) was developed to address this gap.
Purpose of the Study:
- To evaluate the interrater reliability of the HiMAT.
- To determine the retest reliability of the HiMAT.
- To assess the internal consistency of the HiMAT.
Main Methods:
- Three physical therapists assessed 103 individuals with TBI.
- Interrater reliability was assessed by 3 therapists on 17 subjects.
- Retest reliability was assessed by 1 therapist on 20 subjects over 2 days.
- Internal consistency was analyzed using data from all 103 subjects.
Main Results:
- The HiMAT demonstrated very high interrater reliability (ICC=.99).
- The HiMAT showed very high retest reliability (ICC=.99) with a slight, marginal improvement noted at retest.
- Internal consistency was also very high (Cronbach alpha=.97).
Conclusions:
- The HiMAT is a newly developed, reliable tool for assessing high-level mobility in TBI.
- The findings support the use of HiMAT in clinical and research settings for TBI rehabilitation.
- HiMAT specifically addresses the need for measuring advanced mobility not covered by current TBI assessment tools.
