Correlation Between Clinical Measurement Scales for Gross Motor Function

GMFM-66 was performed for participants established on self-independent motion, with importance on allocations, and motion. The emphasis is to detect the grade that greatest reveals the current skills and disabilities of the child regarding motor functions. The new Gross Motor Ability Estimator (GMAE) scoring method for test-retest reliability data showed a high level of stability of the GMFM-66 over time (ICC=0.9932) that did not differ since the original GMFM 88-item test-retest reliability

The BOT-2 are scale used to evaluate fine and gross motion skill development. It's used to classify children with movement control limitation. The test is appropriate for those aged 4 to 21 years. The interrater reliability ranging from 0.92 to 0.99 and construct validity. r = 0.78 (0.56 - 0.86) (test grades / chronological age)

The PDMS-2 is a consistent test that evaluates a child's movement skills. It is norm-referenced and consists of three composites: Fine Motor (FM), Gross Motor (GM), and Total movement composites (TM). GM composite incorporates 151 points from four sub-tests: reflexes, stationary, locomotion, and object manipulation. A 3-point scale scored for each item, with 2 being the highest score. Definite criterion for score of 2 is given when the child achieves the item, 1 is given when the behavior is emerging but not fully met, and 0 is given when the child cannot achieve the point. The highest raw scores of the sub-tests range from 16 to 198. The test-retest reliability of PDMS-2 was found to be r = 0.85 \[24, 25\].
