Assessing Function and Endurance in Adults with Spinal and Bulbar Muscular Atrophy: Validity of the Adult Myopathy Assessment Tool

Table 4

Spearman’s correlation coefficients of the scaled QMA strength values and AMAT Functional subscale items.

	Supine to prone	Push-up	Sit-up	Supine to sit	Arm raise	Sit to stand	Step-up
UE QMA	0.379	0.616	0.623	0.570	0.588	0.614	0.637
LE QMA	0.524	0.559	0.756	0.724	0.471	0.764	0.813
TOTAL QMA	0.487	0.628	0.745	0.687	0.553	0.739	0.777

Note: all 𝑃 values are <0.001, except UE QMA and supine to prone, 𝑃 = 0.004; all QMA values are scaled to body weight.
Abbreviations: UE: upper extremity; LE: lower extremity; AMAT: Adult Myopathy Assessment Tool; QMA: quantitative muscle assessment.
