RESUMO
BACKGOUND: Metrics for movement smoothness include the number of zero-crossings on the acceleration profile (N0C), the log dimensionless jerk (LDLJ), the normalized averaged rectified jerk (NARJ) and the spectral arc length (SPARC). Sensitivity to the handedness and movement type of these four metrics was compared and correlations with other kinematic parameters were explored in healthy subjects. METHODS: Thirty-two healthy participants underwent 3D upper limb motion analysis during two sets of pointing movements on each side. They performed forward- and backward-pointing movements at a self-selected speed to a target located ahead at shoulder height and at 90% arm length, with and without a three-second pause between forward and backward movements. Kinematics were collected, and smoothness metrics were computed. RESULTS: LDLJ, NARJ and N0C found backward movements to be smoother, while SPARC found the opposite. Inter- and intra-subject coefficients of variation were lowest for SPARC. LDLJ, NARJ and N0C were correlated with each other and with movement time, unlike SPARC. CONCLUSION: There are major differences between smoothness metrics measured in the temporal domain (N0C, LDLJ, NARJ), which depend on movement time, and those measured in the frequency domain, the SPARC, which gave results opposite to the other metrics when comparing backward and forward movements.

OBJECTIVE: To determine the benefits associated with brief inpatient rehabilitation for coronavirus 2019 (COVID-19) patients. DESIGN: Retrospective chart review. SETTING: A newly created specialized rehabilitation unit in a tertiary care medical center. PARTICIPANTS: Consecutive sample of patients (N=100) with COVID-19 infection admitted to rehabilitation. INTERVENTION: Inpatient rehabilitation for postacute care COVID-19 patients. MAIN OUTCOME MEASURES: Measurements at admission and discharge comprised a Barthel Activities of Daily Living Index (including baseline value before COVID-19 infection), time to perform 10 sit-to-stands with associated cardiorespiratory changes, and grip strength (dynamometry). Correlations between these outcomes and the time spent in the intensive care unit (ICU) were explored. RESULTS: Upon admission to rehabilitation, 66% of the patients were men, the age was 66±22 years, mean delay from symptom onset was 20.4±10.0 days, body mass index was 26.0±5.4 kg/m2, 49% had hypertension, 29% had diabetes, and 26% had more than 50% pulmonary damage on computed tomographic scans. The mean length of rehabilitation stay was 9.8±5.6 days. From admission to discharge, the Barthel index increased from 77.3±26.7 to 88.8±24.5 (P<.001), without recovering baseline values (94.5±16.2; P<.001). There was a 37% improvement in sit-to-stand frequency (0.27±0.16 to 0.37±0.16 Hz; P<.001), a 13% decrease in post-test respiratory rate (30.7±12.6 to 26.6±6.1; P=.03), and a 15% increase in grip strength (18.1±9.2 to 20.9±8.9 kg; P<.001). At both admission and discharge, Barthel score correlated with grip strength (ρ=0.39-0.66; P<.01), which negatively correlated with time spent in the ICU (ρ=-0.57 to -0.49; P<.05). CONCLUSIONS: Inpatient rehabilitation for COVID-19 patients was associated with substantial motor, respiratory, and functional improvement, especially in severe cases, although there remained mild persistent autonomy loss upon discharge. After acute stages, COVID-19, primarily a respiratory disease, might convert into a motor impairment correlated with the time spent in intensive care.

AIMS: To evaluate if urethrovaginal reflux (UVR) is an underestimated cause of insensible or postmicturition incontinence in adult women. METHODS: An observational and retrospective study was carried out on the computerized records of a neuro-urology department. Female patients who had insensible or postmicturition incontinence were investigated. Retrograde and voiding urethrocystography (UCG), urodynamic evaluation, urethral pressure profilometry, and anamnestic and clinical examination had to be available. RESULTS: Among the 79 adult female patients with insensible or postmicturition incontinence in whom the whole set of required evaluations was achieved, 16 had a UVR (mean age 47 ± 15 years). There were no urethral diverticula, urethrocele, vesicovaginal, or urethrovaginal fistula on their UCG. All of them also had a cystoscopy and a CT urography which did not establish any abnormality. CONCLUSIONS: UVR is not an exclusive pathology of children. This mechanism seems to be an underestimated cause of urinary incontinence in adult women. Retrograde and voiding UCG appears to be the gold standard to confirm the intravaginal reflux.

PURPOSE: To evaluate adherence to anticholinergic therapy (AT) and clean intermittent self-catheterization (CISC) in patients with multiple sclerosis (MS) and to identify factors associated with poor adherence. METHODS: This single-center study prospectively included 49 patients suffering from MS who had been prescribed AT and/or CISC. Adherence was evaluated using a self-report questionnaire. The Expanded Disability Status Scale (EDSS), Patient Global Impression of Improvement, Mini-Mental State Examination, Urinary Symptom Profile, and Hospital Anxiety and Depression (HAD) instruments were administered, and the number of daily anticholinergic pills and/or catheterizations was noted. Whether patients were receiving concomitant intradetrusor botulinum toxin injections was assessed, as were barriers to treatment, side effects, number of spontaneous micturitions, reasons for the prescription, satisfaction, and difficulties. RESULTS: Only 38% of patients were adherent to AT. Experiencing side effects was related to nonadherence (P=0.02). Only 29% of patients were adherent to CISC. More intense voiding dysfunction (P<0.001), a higher frequency of CISC (P=0.03), and a higher EDSS score (P=0.02) were associated with better adherence. Conversely, the HAD score (P<0.001), depression (P<0.001), the persistence of spontaneous micturition (P<0.001), a blocking sensation during catheterization (P=0.04), and the need to adapt one's posture or gesture to perform catheterization (P=0.04) were associated with poorer adherence. CONCLUSIONS: Adherence to AT and CISC was poor in patients with MS suffering from bladder dysfunction. Several factors related to nonadherence were identified in this study, and addressing these factors might help to improve treatment adherence.
