SCAND J REHABIL MED , 2000, vol. 32, n° 3, p. 134-139 Doc n°: 96380 Localisation : Documentation IRR Descripteurs : DA523 - POLYARTHRITE RHUMATOIDE In this study 32 women were investigated in order to elucidate how shoulder rotational muscular strength and upper-extremity impairments are associated with activity limitation in moderate rheumatoid arthritis. A regression analysis was carried out to determine whether these variables could indicate the outcomes of a shoulder-arm disability questionnaire (SDQ) comprising three parts, plus parts of the Health Assessment Questionnaire, the Functional Status Questionnaire and the Sickness Impact Profile. Shoulder-arm and wrist movements were moderate-to-good (r = 0.53, p < 0.01 and r = 0.58, p < 0.01, respectively) in relation to isometric internal rotational strength. The relationship between isokinetic concentric and eccentric internal rotational strength was moderate-to-good (r = 0.59, p < 0.01). Isokinetic eccentric internal rotation strength, shoulder-arm movement, joint tenderness and pain variables together indicated 25-61% (adjusted R2) of the variation in SDQ. Eccentric strength had the highest adjusted R2 (41%) in relation to SDQ 1, covering mainly personal hygiene. Shoulder rotational strength did not indicate the more general instruments. Thus, hand and elbow impairments also are probably important in explaining activity limitations. Langue : ANGLAIS Identifiant basis : 2000212297 |
