Crank Test

anterior apprehension test

2. a test of shoulder stability; apprehension with abduction and external rotation of the joint suggests anterior instability.
Synonym(s): crank test
A clinical test for anterior shoulder instability and dislocation due to a tear in the superior glenoid labrum; the crank test is positive in less than 50% of patients with a tear in the labrum; MRI is a better diagnostic tool

The estimation of [??][O.sub.2]peak from an arm crank test would be of use for clinicians not only for pre-operative risk stratification but also for routine cardiopulmonary exercise test (CPET) in adults with restricted lower limb mobility.
Each participant performed both the Wasserman's cycle ergometer and arm crank test in a randomly-assigned order separated by at least five days to assure for full recovery.
In contrast, RER values were significantly higher in the arm crank test in comparison with the cycle ergometer test; this may be directly linked to the greater lactic acid accumulation per regional skeletal muscle mass and the lower oxidative capacity of the exercising muscles in arm cranking.
In a standard two-minute hand crank test, the Eton outperformed the competition and lasted 13 minutes on cranking.
Eight outcome measures were used from the graded arm crank test. Resting [??][O.sub.2] and [O.sub.2] pulse were determined as the average over the last 60 s of quiet sitting.
Based on the submaximal [??][O.sub.2] and HR values during the arm crank test, this study shows that cardiorespiratory fitness might have increased during the intervention.
To test for tears in the labrum, use the crank test, which is performed with the patient in the seated or supine position.
These tests are reliable and valid (5,6,7,8), as well as the crank test for SLAP lesions in the glenohumeral joint, which is valid, although reliability is unknown (9,10).
The crank test, described by Liu and associates, (24) is performed with the patient either upright or supine.
The crank test is used to identify chronic labral injury, whereas the active compression test (25) (Figure 4) indicates labral injury if pain is deep in the shoulder.
The Wingate arm crank test (Warm crank) was performed using an isokinetic arm ergometer (Cybex UBE 2462, Owatonna, MN) and consisted of 30 seconds maximal effort at a constant 120 rpm rotation speed.
Pearson product moment correlation (PM) and statistical power (1-[beta]) values between anaerobic work capacity (AWC) and the variables obtained in the Wingate arm crank test.
