At each follow-up, Tnasal IOP was statistically lower than at baseline, although the reduction was not as great as that of Tcenter IOP. A 2 to 3 mm Hg drop in Tnasal up to 6 months after LASIK should be expected. An alternative would be to measure IOP with the Tono-Pen on the nasal side to fit the tip to the relatively unchanged nasal side of the cornea.

From viewpoint of the thorax-pelvis coordination, patients with IS had less gait stability in the trunk than controls.

Groups experience collective autonomy restriction whenever they perceive that other groups attempt to limit the freedom of their group to determine and express its own identity. We argue that collective autonomy restriction motivates groups (both structurally advantaged and disadvantaged) to improve their power position within the social hierarchy. Four studies spanning real-world (Studies 1 and 2) and lab-based (Studies 3 and 4) intergroup contexts supported these ideas. In Study 1 (N=311), Black Americans' (a relatively disadvantaged group) experience of collective autonomy restriction was associated with greater support for collective action, and less system justification. In Study 2, we replicated these findings with another sample of Black Americans (N=292). We also found that collective autonomy restriction was positively associated with White Americans' (a relatively advantaged group, N=294) support for collective action and ideologies that bolster White's dominant position. In Study 3 (N=387, 97 groups), groups that were susceptible to being controlled by a high-power group (i.e., were of low structural power) desired group power more when their collective autonomy was restricted (versus supported). In Study 4 (N=803, 257 groups) experiencing collective autonomy restriction (versus support) increased low-power group members' support of collective action, decreased system justification, and evoked hostile emotions, both when groups were and were not materially exploited (by being tasked with more than their fair share of work). Across studies, we differentiate collective autonomy restriction from structural group power, other forms of injustice, group agency, and group identification. These findings indicate that collective autonomy restriction uniquely motivates collective behavior.

Transforaminal epidural injection is used to treat radicular pain. However, there is no objective method of assessing pain relief following transforaminal injection. Perfusion index is a metric for monitoring peripheral perfusion status. This study evaluates the correlation between perfusion index change and analgesic efficacy in transforaminal blocks for lumbosacral radicular pain. We retrospectively analyzed data of 100 patients receiving transforaminal block for lumbosacral radicular pain. We assessed perfusion index before treatment and at 5, 15, and 30 min following the block. We defined responders (group R) and non-responders (group N) as those with ≥50% and <50% pain reduction, respectively, 30 min following block. Clinical data and perfusion index of the groups were analyzed. Ninety-two patients were examined, of whom 57 (61.9%) and 35 (38.0%) patients reported ≥50% and <50% pain reduction, respectively. Group R had a significantly higher perfusion index change ratio 5 min following the block (p = 0.029). A perfusion index change ratio of ≥0.27 was observed in group R (sensitivity, 75.4%; specificity, 51.4%; AUC (area under the curve), 0.636; p = 0.032). A perfusion index change ratio of ≥0.27 at 5 min after block is associated with, but does not predict improvement in, pain levels following lumbosacral transforaminal block.
