Abstract
Study designClinical measurement. PurposeThe test-retest reliability of maximal grip strength measurements (MGSM) is examined in subjects for 12 weeks post-stroke together with maximal grip strength recovery and the maximal-grip and upper-extremity strength measurements' relationship with capacity and performance test scores. MethodsA Jamar dynamometer and the Motricity Index (MI) were used for strength measurements. The Chedoke Arm and Hand Activity Inventory and ABILHAND questionnaire for evaluating capacities and performances. ResultsMGSM were reliable (Intraclass Correlation Coefficients = 0.97–0.99, Minimal Detectable Differences = 2.73–4.68 kg). Among the 34 participants, 47% did not have a measurable grip strength one week post-stroke but 50% of these recovered some strength within the first eight weeks. The MGSM and MI scores were correlated with scores of tests of capacity and performance (Spearman's Rank Correlation Coefficients = 0.69–0.94). ConclusionsMGSM are reliable in the first weeks after a stroke. Level of evidenceN/A.
