Key Descriptions

  • RMA is a performance-based measure developed specifically for the stroke population with the intent to be used for both the clinic and research purposes.
  • Consists of 3 sections:
    1) gross function (RMA-gf)
    2) leg and trunk (RMA-lt)
    3) arm (RMA-a).
  • Each item is scored either yes ‘1’ or no ’0’. It is based on Guttman scaling, which presumes that each subsequent item is of a more difficult nature. To advance to the next question, one must score “1” on an item, otherwise the test is stopped.

Professional Association Recommendation

Recommendations for use of the instrument from the Neurology Section of the American Physical Therapy Association’s Stroke Taskforce (StrokEDGE) are listed below. These recommendations were developed by a panel of research and clinical experts using a modified Delphi process.

Considerations

  • Used extensively in research and clinic, primarily in Europe.

  • Designed for the stroke population and used primarily with that population. Gross motor section has been used with TBI and the elderly to a lesser extent.

  • Several studies have noted that their results show the actual hierarchy of the test items to be different from the original test. Therefore, when administering the test, it is recommended that all items be tested rather than stopping the arm or gross functions test when 3 consecutive items are scored a “0”, as originally instructed.

Stroke

back to Populations

Minimally Clinically Important Difference (MCID)

  • Collen et al (1990) found that a 3 point change in the total RMA score represented a clinically meaningful change.

Test/Retest Reliability

Stroke: (Lincoln and Leadbitter 1979)

  • Adequate test-retest reliability

  • RMA-gf, r = 0.66

  • RMA-lt, r = 0.93

  • RMA-a, r = 0.88

Internal Consistency

Subacute Stroke: (Kurtais et al, 2009; n = 107; mean age = 62.4 (12.8) years; mean time since onset = 5.6 (SD = 11.2, range = 0.5-78) months; patients in inpatient rehabilitation unit)

  • Good internal consistency

  • RMA-gf - Cronbach’s Alpha = 0.93, ICC = 0.88

  • RMA-lt - Cronbach’s Alpha = 0.88, ICC = 0.84

  • RMA-a - Cronbach Alpha = 0.95, ICC = 0.93

Criterion Validity (Predictive/Concurrent)

Concurrent Validity

Chronic Stroke: (Rousseaux et al, 2012; n = 46; 14.1 (25.9) months post stroke)

  • Excellent validity with Upper Limb Assessment in Daily Living (ULADL): correlation of Global Questionnaire (Q) and Test scores (T) with Rivermead Gross Motor Assessment (RMA score) (r = 0.80 and 0.88, respectively; p < 10-4)

 

Predictive Validity

Chronic Stroke: (Collen and Wade, 1990):

  • Low RMA scores at 6 weeks post stroke predicted poor prognosis to ambulate.

Construct Validity

Acute to Subacute Stroke: (Soyuer and Soyuer 2005)

  • High convergent validity between total RMA and FIM

  • 7-10 days post stroke: r = 0.87 for total FIM, r = 0.90 for motor FIM

  • 3 months post stroke: r = 0.88 for total FIM, r = 0.89 for motor FIM

Subacute Stroke: (Kurtais et al, 2009; n = 107; mean age = 62.4 (12.8) years; mean time since onset = 5.6 (SD = 11.2, range = 0.5-78) months; patients in inpatient rehabilitation unit)

  • Moderate to High external construct validity when compared to FIM score

Chronic Stroke: (Van de Winckel et al, 2007; mean time post stroke = 8 months; RMA-a only)

  • Investigated the construct validity and unidimensionality of the RMA-a. Four items were removed from the scale and 2 subsets were identified through statistical analysis to create a scale that fit the Rasch model. The revised RMA-arm section met criteria for validity and unidimensionality.

Acute-Subacute Stroke: (Houwink et al, 2011; n = 21; mean age = 61.7 ± 7.9 years; time since stroke onset = within 4 months; only used RMA-a)

  • Strong cross-sectional correlation of RMA-a with SULCS (Stroke Upper Limb Capacity Scale) with ρ = 0.85

  • Moderate longitudinal correlation of RMA-a with SULCS (ρ = 0.48)

Responsiveness

Subacute Stroke: (Kurtais et al, 2009; n = 107; mean age = 62.4 (12.8) years; mean time since onset = 5.6 (SD = 11.2, range = 0.5-78) months; patients in inpatient rehabilitation unit)

  • Good sensitivity

  • RMA-gf ES = 0.51, SRM = 0.83

  • RMA-lt ES = 0.45, SRM = 0.86

  • RMA-a ES = 0.61, SRM = 1.20

Brain Injury

back to Populations

Criterion Validity (Predictive/Concurrent)

Concurrent Validity

Brain Injury: (Endres et al, 1990)

  • RMA has excellent correlation with BI across each assessment period initial (r = 0.84), one month (0.78), and one year (0.63).

Floor/Ceiling Effects

TBI: (Williams et al, 2006)

  • A Large ceiling effect was noted on the Gross Motor Function Subscale of the RMA when compared to HIMAT ceiling effect was noted on the Gross Motor Function Subscale of the RMA when compared to HIMAT
