OBJECTIVES: To investigate (1) the intrarater, interrater, and test-retest
reliability of the timed 360 degrees turn test in subjects with stroke; (2) the
concurrent validity of the timed 360 degrees turn test by exploring its
correlation with other measures of stroke-specific impairments; and (3) the
cutoff times that best discriminate individuals with stroke from healthy older
adults. DESIGN: Cross-sectional study. SETTING: University-based rehabilitation
center. PARTICIPANTS: Individuals with chronic stroke (n=72) and healthy
individuals (n=35) of similar age (N=107). INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: The timed 360 degrees turn test was administered along with the
Fugl-Meyer assessment of the lower extremity, measurement of muscle strength of
ankle dorsiflexors and plantarflexors using a handheld dynamometer, Berg Balance
Scale, limit of stability test, five times sit-to-stand (FTSTS) test, 10-m walk
test, and timed Up and Go (TUG) test. RESULTS: The 360 degrees turn times showed
excellent intrarater, interrater, and test-retest reliability in individuals with
stroke. A minimal detectable change of .76 seconds was found for subjects turning
toward the affected side and 1.22 seconds for subjects turning toward the
unaffected side. The 360 degrees turn times were found to correlate significantly
with Fugl-Meyer assessment of the lower extremity scores, dosiflexor strength of
the affected ankle, plantarflexor strength of both ankles, FTSTS test times,
balance performance, gait speed, and TUG test times. The 360 degrees turn times
of 3.43 to 3.49 seconds were shown to discriminate reliably between individuals
with stroke and healthy older adults. CONCLUSIONS: The timed 360 degrees turn
test is a reliable and an easily administered clinical tool to assess the turning
ability of subjects with chronic stroke.
