Table 6.
Comparison between the relative range of motion and angular velocity measures between sensors obtained from spatial processing of motion signals while turning among stroke survivors (SS) and healthy individuals (HI). The significant measures’ p-values are shown in bold. The dark pies depict the part of turning in consideration.
