Rectal cancer operative procedures were high anterior (n =1), intersphincteric (n =2), or abdominoperineal (n =2) resection, followed by radical prostatectomy with vesico-urethral anastomosis.

Immediate effect of standing and sit-to-stand training on postural vertical for backward disequilibrium following stroke: a case report.

Background: Effects of therapeutic interventions backward disequilibrium following stroke are scarcely reported.

Objective: To clarify the effects of standing and sit-to-stand/stand-to-sit training aimed at postural deviation in the anterior direction for backward disequilibrium and posterior deviation of subjective postural vertical.

Case Description: The participant presented with backward disequilibrium and pontine hemorrhage-associated sensory impairment of the extremities.

Effects of visual-motor illusion in stroke hemiplegic patients with left-side personal neglect: A report of two cases.

Personal neglect is the neglect of self-body space, which often occurs in patients with unilateral spatial neglect (USN), but lacks a dedicated rehabilitation. The purpose of this study was to investigate the effects of visual-motor illusion (VMI) on two-stroke hemiplegic patients with left-side personal neglect. Case 1 was a 53-year-old man diagnosed with a right lenticulostriate artery infarction.

Retrospective comparison of rectal toxicity between carbon-ion radiotherapy and intensity-modulated radiation therapy based on treatment plan, normal tissue complication probability model, and clinical outcomes in prostate cancer.

This retrospective study assessed the treatment planning data and clinical outcomes for 152 prostate cancer patients: 76 consecutive patients treated by carbon-ion radiation therapy and 76 consequtive patients treated by moderate hypo-fractionated intensity-modulated photon radiation therapy. These two modalities were compared using linear quadratic model equivalent doses in 2 Gy per fraction for rectal or rectal wall dose-volume histogram, 3.6 Gy per fraction-converted rectal dose-volume histogram, normal tissue complication probability model, and actual clinical outcomes.

Mean heart dose-based normal tissue complication probability model for pericardial effusion: a study in oesophageal cancer patients.

We investigated the normal tissue complication probability (NTCP) of the incidence of pericardial effusion (PCE) based on the mean heart dose (MHD) in patients with oesophageal cancer treated with definitive chemoradiotherapy. The incidences of PCE in any grade (A-PCE) and symptomatic PCE (S-PCE) were evaluated separately. To identify predictors for PCE, several clinical and dose-volume parameters were analysed using a receiver operating characteristic (ROC) curve and multivariate regression analysis.

Objectives: Sitting ability during the acute phase after stroke is a useful indicator of functional outcomes; however, factors that affect this ability have not been evaluated. Therefore, this study aimed to identify and evaluate factors that affect sitting ability in the acute phase after stroke.

Materials And Methods: This multicenter prospective cohort study included hemispheric stroke patients who underwent an inpatient rehabilitation program after acute stroke from five acute care hospitals.

Starting position effects in the measurement of the postural vertical for pusher behavior.

Pusher behavior (PB) is a severe lateral postural disorder that involves a disturbed subjective postural vertical (SPV) in the frontal plane. SPV is measured by determining the mean value and standard deviation of several trials beginning on both the contralesional- and ipsilesional-tilted positions. However, the postural representation, when passively tilted to the contralesional versus ipsilesional position, is different between patients with and without PB.
