This study investigates the feasibility, reliability, and correlations
of recommended functional tests in lung transplant recipients shortly after
surgery. DESIGN: This is an observational study.
METHODS: Fifty patients (28
females) performed well-standardized maximum isometric back extension in a
sitting position, handgrip strength, and Biering-Sorensen endurance tests shortly
before discharge from the acute hospital, shortly thereafter, and 2 mos later
after subacute rehabilitation. RESULTS: Back extension testing was well feasible,
but only two thirds of the patients could perform the Biering-Sorensen test at
baseline and they experienced a greater number of minor but no major adverse
events. Absolute reliability measures and the intraclass correlation coefficients
were excellent for the strength (0.97-0.98 [0.95-0.99]) and good for the
endurance tests (0.69 [0.26-0.87]). Handgrip revealed high correlation with back
strength (>/=0.75) but not with Biering-Sorensen scores. CONCLUSIONS:
Well-controlled maximum back strength testing is feasible and reliable, and the
scores are highly correlated with grip strength in lung transplant recipients
shortly before hospital discharge. The Biering-Sorensen test should be limited to
patients without dominant weakness and/or fear. Future research should
investigate whether grip instead of back extension strength can safely be used
for proper exercise prescription.
