Clinimetric evaluation of measurement tools used in hand therapy to assess activity and participation.

STUDY DESIGN: Systematic review. INTRODUCTION: A number of measurement tools with strong clinimetric properties address activities and participation in hand-injured persons. PURPOSE OF THE STUDY: To evaluate clinimetric quality of measurement tools assessing activities and participation in patients with hand injuries. METHODS: The electronic databases Medline, Cochrane library, EMBASE, PEDro, Cumulative Index to Nursing and Allied Health Literature (ClNAHL), and Allied and Complementary Medicine Database (AMED) were searched for appropriate literature. Descriptive data of included tools were given, and their clinimetric quality was scored with specific criteria. RESULTS: The literature search identified 696 publications, referring to 15 measurement tools that met the inclusion criteria. For most of the included tests, applicability was good, whereas information on clinimetric properties was often lacking, especially for the performance tests. Overall, the Disabilities of the Arm, Shoulder, and Hand (DASH) was the most extensively studied tool with positive ratings for all criteria, closely followed by the Michigan Hand Outcomes Questionnaire (MHQ). Of the performance tests, the Functional Dexterity Test (FDT) received the best ratings. CONCLUSIONS: Optimal measurement tool selection depends highly on the purpose of measurement and the type of hand injury. LEVEL OF EVIDENCE: 2a-.

Onset of electrical stimulation leg cycling in individuals with paraplegia.

PURPOSE: This study investigated cardiovascular and hemodynamic responses during the transition from rest to electrical stimulation-induced leg cycling exercise (ES-LCE) in individuals with chronic paraplegia (PARA). METHODS: Ten PARA (T(4)-T(9); ASIA A) participated in this study. Heart rate (HR), mean arterial pressure (MAP), stroke volume (SV), and cardiac output (Q) were measured on a beat-to-beat basis at rest and during the first 60 s of ES-LCE. RESULTS: PARA exhibited two discrete MAP responses during ES-LCE. Those with high thoracic lesions (HIGH: T(4) -T(6), = 5) responded to ES-LCE with a significant rise in MAP (maxdelta 8.3 +/- 3.6 mm Hg), whereas MAP did not exhibit any sustained change from resting values during ES-LCE in those subjects with lower lesions (LOW: T -T, = 5). In HIGH PARA, the immediate increase in MAP corresponded to a decrease in HR (maxdelta 6.8 +/- 3.1 b x min(-1)), which returned toward resting levels by the end of 60 s. In contrast, for LOW PARA there was no change in HR from resting levels during transition to ES-LCE. In both subgroups, SV and Q were not significantly increased during ES-LCE. CONCLUSION: These results suggest that the on-transient responses of MAP during ES-LCE in HIGH PARA elicited reflex changes in HR via the arterial baroreflex, whereas in LOW PARA, an unchanged HR from rest was likely due to a constant MAP during ES-LCE.
