Objective: To analyze the amount of weight-bearing during tilt table increments, with a review of neutral andunilateral knee flexion postures.
Methods: There were 17 healthy participants enrolled in this study. The subjects were tilted from 10° to 90°, andtheir body weight was measured at each 10° increment. In the first test, both plantar pressures, with the subjectsin neutral posture, were recorded. During the second and third tests, the angle of inclination was thus recordedand increased, with the subjects in unilateral knee flexion posture; flexion was maintained at 25° by attaching acylindrical support to the tilt table at the level of the popliteal fossa.
Results: The study was divided into two types of postures: neutral and unilateral knee flexion. The percentageof body weight (%BW) between each leg during neutral posture was noted as not being statistically significant.The %BW of one side during tilt table inclination was significantly different between the two postures at 10° to80° (p<0.05). The weight during unilateral knee flexion posture was lower as analyzed, regardless of tilt tableinclination compared with that in neutral posture. We note that fifty percent of the ratio of %BW was noted at33.12° and 38.76° in neutral and flexion postures, respectively.
Conclusion: The unilateral knee flexion could induce the effect of decreased body weight compared with nonflexionside. The results of this study will help in setting a safe and quantitative percentage of weight-bearing onthe lower extremity during tilt training.
