BackgroundStandardized outcome measures with high clinical utility are of paramount importance for clinical practice.ObjectiveThe purpose of this study was to examine interrater and intrarater reliability, construct validity, discriminant ability, and smallest detectable differences of the sit-to-stand test (STS), Timed “Up & Go” Test (TUG), and bed mobility test for people with Parkinson disease (PD).DesignA cross-sectional, psychometric evaluation study was conducted.MethodsA group of individuals with PD (PD group) and a group of individuals who were healthy (control group) were recruited through local PD groups and assessed in a movement laboratory in their “on” phase. Measurements of time to perform one STS, TUG, and bed mobility test were collected based on video recordings of that single performance.ResultsThirty-eight individuals with PD (Hoehn and Yahr stages I–IV) and 19 age-matched control participants were recruited. Intraclass correlation coefficients for interrater and intrarater reliability for the PD group ranged from .95 to .99. Bland-Altman plots showed mean differences close to zero and narrow confidence intervals. Construct validity was established by means of moderate to good Spearman rho correlation coefficients with part III of the Unified Parkinson's Disease Rating Scale and the Hoehn and Yahr stage (range=.51–.63). Timings of all tests discriminated participants in the PD group from those in the control group and participants in the PD group in Hoehn and Yahr stages I and II from those in Hoehn and Yahr stages III and IV but did not discriminate “nonfallers” or those with single falls from repeat “fallers” or “nonfreezers” from “freezers.” Applicable smallest detectable differences were established.LimitationsThe results are not generalizable to people in the late stage of PD (Hoehn and Yahr stage IV: n=3).ConclusionsTimings of video recordings of 3 functional mobility tests with high clinical utility showed good psychometric properties for community-dwelling, ambulatory people with PD.

The Impact

Abstract Background and Purpose. Functional mobility in people with advanced Parkinson disease, some of whom have a variable response to drug treatment, is often difficult to evaluate. The objectives of this study were to investigate the interrater reliability of measurements obtained with a scale designed to measure mobility and to determine the impact of self-rated dyskinesias and fluctuations on the measure. Subjects. Twenty-nine people with Parkinson disease and with disability and considerable disease duration (X̄=11.7 years, SD=4.9, range=6–22) took part in the study. Methods. The subjects' performance on a 10-item scale was videotaped. The videotapes were then scored by 2 independent raters, and the scores were used to determine interrater reliability. The stability of 6 repeated measurements was examined in the home situation, taking into account self-rated fluctuations of motor performance. Results. Weighted Kappa values of agreement (.86–.98) confirmed the reliability between testers. Measurement during the “on” phase (when medication was working optimally) and the “off” phase (when the action of medication was strongly decreased or absent) led to different measurements. Measuring frequently within “on” and “off” phases gave relatively stable measurements for total function, bed transfers, and gait akinesia, the latter during the “off” phase only (intraclass correlation coefficients [ICCs]=.70–.93). However, more modest repeatability applied to transfers from a chair (ICC=.65–.67). Conclusion and Discussion. To ensure valid results in future effect studies, clinical differentiation between “on” and “off” phase measurements is proposed on the basis of patients' own perception of their medication status.

Background and Purpose This study examined the interrater and intrarater reliability, concurrent validity, and criterion validity of the Tinetti Mobility Test (TMT) as a fall risk screening tool in individuals with Parkinson disease (PD). Subjects Thirty individuals with PD voluntarily participated in the study, and data from a retrospective review of 126 patient records were included. Methods Physical therapists and physical therapist students rated live and videotaped performances of the TMT. Tinetti Mobility Test scores were correlated with Unified Parkinson's Disease Rating Scale (UPDRS) motor scores and comfortable gait speed. The ability of the TMT to accurately assess fall risk was determined. Results Interrater and intrarater reliability was good to excellent (intraclass correlation coefficient of >.80). Tinetti Mobility Test scores correlated with UPDRS motor scores (rs=−.45) and gait speed (rs=.53). The sensitivity and specificity of the TMT to identify fallers were 76% and 66%, respectively. Discussion and Conclusion The TMT is a reliable and valid tool for assessing the mobility status of and fall risk for individuals with PD.

The actor/observer effect was examined by Storms in a 1973 study which manipulated perceptual orientation using video recordings. Storms' study was complex and some of his results equivocal. The present study attempted to recreate the perceptual reorientation effect using a simplified experimental design and an initial difference between actors and observers which was the reverse of the original effect. Female undergraduates performed a motor co-ordination task as actors while watched by observers. Each person made attributions for the actor's behaviour before and after watching a video recording of the performance. For a control group the video recording was of an unrelated variety show excerpt. Actors' initial attributions were less situational than observers'. Both actors and observers became more situational after the video replay but this effect occurred in both experimental and control groups. It was suggested the passage of time between first and second recording of attributions could account for the findings and care should be taken when interpreting Storms' (1973) study and others which did not adequately control for temporal effects.

AbstractThe lack of a Swedish patient-reported outcome instrument for eosinophilic esophagitis (EoE) has limited the assessment of the disease. The aims of the study were to translate and validate the Eosinophilic Esophagitis Activity Index (EEsAI) to Swedish and to assess the symptom severity of patients with EoE compared to a nondysphagia control group. The EEsAI was translated and adapted to a Swedish cultural context (S-EEsAI) based on international guidelines. The S-EEsAI was validated using adult Swedish patients with EoE (n = 97) and an age- and sex-matched nondysphagia control group (n = 97). All participants completed the S-EEsAI, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Oesophageal Module 18 (EORTC QLQ-OES18), and supplementary questions regarding feasibility and demographics. Reliability and validity of the S-EEsAI were evaluated by Cronbach’s alpha and Spearman correlation coefficients between the domains of the S-EEsAI and the EORTC QLQ-OES18. A test–retest analysis of 29 patients was evaluated through intraclass correlation coefficients. The S-EEsAI had sufficient reliability with Cronbach’s alpha values of 0.83 and 0.85 for the “visual dysphagia question” and the “avoidance, modification and slow eating score” domains, respectively. The test–retest reliability was sufficient, with good to excellent intraclass correlation coefficients (0.60–0.89). The S-EEsAI domains showed moderate correlation to 6/10 EORTC QLQ-OES18 domains, indicating adequate validity. The patient S-EEsAI results differed significantly from those of the nondysphagia controls (p < 0.001). The S-EEsAI appears to be a valid and reliable instrument for monitoring adult patients with EoE in Sweden.

AbstractPost-operative nasal medications are commonly used following routine septal or turbinate surgery but their efficacy in removing blood clots, improving the sensation of a patent airway and promoting healing are unknown. This prospective randomized trial of patients undergoing septal and/or turbinate surgery assessed the efficacy of three commonly used nasal medicines, 0.5 per cent ephedrine hydrochloride nasal drops, betamethasone sodium phosphate (Betnosol®) nose drops and alkaline nasal douches, in producing the sensation of a patent airway in the 14 days following surgery. Ninety-seven patients were randomized into the three treatment groups and a control group who received no nasal medication. Patients assessed their nasal patency by means of a visual analogue scale (VAS) and any complications of treatment were recorded. Statistical analysis of the 76 complete sets of results using the Mann-Whitney U-test showed that there was a significant difference in the distribution of all of the treatments for each of the time intervals (p<0.05). Glass rank biserial correlation coefficients were all small (rg<0.085) but the most significant differences were between ephedrine and the control group at two hours, two, seven and 10 days (0.02, 0.054, 0.057, 0.085 respectively), alkaline nasal douches being most significant at four and 14 days (0.06 and 0.0722 respectively).

Background: Paratonia is a distinctive form of hypertonia, causing loss of functional mobility in early stages of dementia to severe high muscle tone and pain in the late stages. For assessing and evaluating therapeutic interventions, objective instruments are required. Objective: Determine the psychometric properties of the MyotonPRO, a portable device that objectively measures muscle properties, in dementia patients with paratonia. Methods: Muscle properties were assessed with the MyotonPRO by 2 assessors within one session and repeated by the main researcher after 30 min and again after 6 months. Receiver operating characteristic curves were constructed for all MyotonPRO outcomes to discriminate between participants with (n = 70) and without paratonia (n = 82). In the participants with paratonia, correlation coefficients were established between the MyotonPRO outcomes and the Modified Ashworth Scale for paratonia (MAS-P) and muscle palpation. In participants with paratonia, reliability (intraclass correlation coefficient) and agreement values (standard error of measurement and minimal detectable change) were established. Longitudinal outcome from participants with paratonia throughout the study (n = 48) was used to establish the sensitivity for change (correlation coefficient) and responsiveness (minimal clinical important difference). Results: Included were 152 participants with dementia (mean [standard deviation] age of 83.5 [98.2]). The area under the curve ranged from 0.60 to 0.67 indicating the MyotonPRO is able to differentiate between participants with and without paratonia. The MyotonPRO explained 10-18% of the MAS-P score and 8-14% of the palpation score. Interclass correlation coefficients for interrater reliability ranged from 0.57 to 0.75 and from 0.54 to 0.71 for intrarater. The best agreement values were found for tone, elasticity, and stiffness. The change between baseline and 6 months in the MyotonPRO outcomes explained 8-13% of the change in the MAS-P scores. The minimal clinically important difference values were all smaller than the measurement error. Conclusion: The MyotonPRO is potentially applicable for cross-sectional studies between groups of paratonia patients and appears less suitable to measure intraindividual changes in paratonia. Because of the inherent variability in movement resistance in paratonia, the outcomes from the MyotonPRO should be interpreted with care; therefore, future research should focus on additional guidelines to increase the clinical interpretation and improving reproducibility.

Background: Although traditional Chinese Yijinjing Qigong Exercise (YJJQE) is popularly used in China, to alleviate symptoms of people with knee osteoarthritis (KOA), no randomized controlled trials (RCTs) are available to evaluate the effects of YJJQE in patients with KOA. The purpose of this trial is to assess the clinical efficacy of YJJQE for patients with KOA.Methods: A total of 50 participants clinically diagnosed with KOA are randomly (1:1) assigned to the YJJQE group (n = 25) and to the stretching training exercise (STE) group (n = 25), for a 40-min exercise session twice a week for 12 weeks. All outcome measures are collected at baseline and at 12-week ending intervention, which includes the primary outcomes of Western Ontario and McMaster Universities Osteoarthritis Index Scale (WOMAC), the secondary outcomes of visual analog scale (VAS), mental component summary (MCS), physical component summary (PCS), Beck depression inventory (BDI), perceived stress scale (PSS), Berg balance scale (BBS), and the Gait functional mobility data.Results: The YJJQE group did not have any significant changes compared to the control group on the WOMAC score after the 12-week intervention (P &gt; 0.05), though the YJJQE group demonstrated better performance in MCS, BDI, and PSS (P = 0.002, P = 0.001, and P = 0.026, respectively) than the control group. No serious adverse events occurred in either group, and only mild muscle soreness was reported during both exercise treatments.Conclusion: Because no difference between both groups was shown, with regards to the primary outcome measurement (WOMAC), it can hardly explain that the YJJQE had an advantageous effect on patients experiencing the pain and dysfunction of knee osteoarthritis. However, compared to the control group, YJJQE appeared to be associated with improvements in psychological well-being including reduced stress, anxiety, depression, and mood disturbance to manage KOA. Further trials with larger sample sizes and follow-up studies will be required.Clinical Trial Registration:https://www.chictr.org.cn/edit.aspx?pid=60357&amp;htm=4, ChiCTR2000037256.

Background. The individual and typological features of the central nervous system are interpreted as highly genetically determined. Each somatotype is characterized by morphofunctional features of the activity of different systems, including the circulatory system. Objective. The aim of the research was to study the features of the main individual and typological parameters of higher nervous activity in persons of different somatotype with normal and high blood pressure (BP). Methods. In the control group of the surveyed patients the BP value corresponded to the optimal level according to the WHO classification (125 people). The second group consisted of individuals, whose systolic blood pressure exceeded 130 mmHg at the time of the study and (or) diastolic – 85 mmHg (135 people). Somatotyping technique by Carter and Heath was used. Functional mobility (FMNP) and strength of nervous processes (SNP) were determined using the Diagnost-1 program (Makarenko and Lizogub). Results. In the individuals with predominance of ecto- and mesomorphic somatotype component, higher levels of major nervous processes were reported in response to strenuous processing of information, which was associated with more advanced mechanisms of information processing, its neurophysiological support. In people with endomorphic somatotype the lower levels of FMNP and SNP were clearly detected that could indicate that the speed characteristics of the nervous processes in them are at a lower level. Conclusions. In normal blood pressure, the highest indicator of FMNP was found in the individuals with predominance of ecto- and mesomorphic component. In the group with high blood pressure, the indicator at the level below the average was in endomorphs. Predominance of the ectomorphic component tended to increase in the surveyed, and in the mesomorphs was at the average level. The lowest level of SNP was found in the individuals with endomorphic somatotype of both groups.
