Measuring pain intensity in older patients: a comparison of five scales.

BACKGROUND AND AIMS: Pain is common in older individuals. In order to understand and treat pain in this group, reliable and valid measures are needed. This study aimed to evaluate: (1) the validity, utility, incorrect response rates and preference rates of 5 pain rating scales in older individuals; and (2) the associations between age, education level, and cognitive function and both (a) incorrect response and (b) preference rates. METHODS: Two hundred and one orthopedic clinic outpatients ≥ 65 years old were asked to rate their current pain, and least, average, and worst pain intensity in the past week using 5 scales: Verbal Numerical Rating Scale (VNRS), Faces Pain Scale - Revised (FPS-R), Verbal Rating Scale (VRS), Numerical Rating Scale (NRS), and Visual Analogue Scale (VAS). Participants were also asked to indicate scale preference. We computed the associations between each measure and a factor score representing the shared variance among the scales, the incorrect response and scale preference rates, and the associations between incorrect response and preference rates and age, education level, and cognitive function. The incorrect responses included being unable to respond, providing more than one response, responses outside a range, providing range answers rather than fixed answers, and responses indicating 'least > average,' 'least > worst,' and 'average > worst'. RESULTS: The findings support validity of all 5 scales in older individuals who are able to use all measures. The VNRS had the lowest (2%) and the VAS had the highest (6%) incorrect response rates. The NRS was the most (35%) and the VAS was the least (5%) preferred. Age was associated with the incorrect response rates of the VRS and VAS, such that older individuals were less likely to use these scales correctly. Education level was associated with the incorrect response rates of the FPS-R, NRS and VAS, such that those with less education were less likely to use these measures correctly. Cognitive function was not significantly associated with incorrect response rates. Age, education level and cognitive function were not significantly associated with scale preference. CONCLUSIONS: Although all five scales are valid, the VNRS evidences the best overall utility in this sample of older individuals with pain. The NRS or FPS-R would be fine alternatives if it is not practical or feasible to use the VNRS.

An international clinical perspective on functioning and disability in adults with cerebral palsy.

BACKGROUND: This international, multi-center cross-sectional study is one of the preparatory studies in the development of the International Classification of Functioning, Disability and Health (ICF) Core Sets for adults with cerebral palsy (CP) to describe their functioning and health. OBJECTIVE: To identify the most common problems in functioning of adults with CP presenting in healthcare services, and facilitating and hindering environmental factors, using the ICF as a reference. METHODS: Participants were adults with CP who visited healthcare services in the Netherlands, Sweden, Thailand, and the United States. Structured interviews were performed using an adapted version of the generic ICF checklist 2.1a (106 categories) to rate the participant's functioning and the impact of environmental factors. Descriptive statistics were used for frequency analysis. RESULTS: In total, 101 participants were included, of whom 69 without intellectual disability (mean age ± SD of 38.4 ± 14.7 y; 85.5% with spastic type of CP; Gross Motor Function Classification System (GMFCS) levels I-V) and 32 with intellectual disability (mean age ± SD of 25.0 ± 6.4 y; 71.9% with spastic type of CP; GMFCS levels I-V). A total of 104 ICF categories in the ICF checklist were frequently present in adults with CP: 27 body functions, 4 body structures, 53 activities and participation, and 20 environmental factors. CONCLUSIONS: The most common problems of adults with CP presenting in healthcare services are diverse and highly prevalent. The study results add the clinical perspective on relevant categories of functioning to the basis for developing the ICF Core Sets for adults with CP.

Correlation of the gait speed with the quality of life and the quality of life classified according to speed-based community ambulation in Thai stroke survivors.

BACKGROUND: Gait abnormality commonly resulted from stroke which affected patients living and probably quality of life (QOL). OBJECTIVE: To assess the relationship between gait speed and the QOL in Thai stroke patients and to compare the QOL among three patient groups that were categorized by gait speed: i) household ambulators <0.4 m/s, ii) limited community ambulators 0.4-0.8 m/s and iii) community ambulators >0.8 m/s. METHODS: This was a cross-sectional descriptive research study. The demographic data of 92 stroke patients at Songklanagarind Hospital in Thailand were collected. The gait speed was calculated by the 10 meter walk test. The Thai version of the Stroke Impact Scale (SIS) 3.0 evaluated the QOL of the patients. RESULTS: The gait speed was correlated with the SIS score (r = 0.64, p <  0.001). The relationship between the gait speed and most domains of the SIS (i.e., strength, mobility, hand function, activities of daily living [ADL], emotion, social participation and thinking of recovery) were also statistically significant. The community ambulators had a higher total SIS score (729.8) than the limited community (600.8) or household ambulators (478.8) (p <  0.001). For each SIS domain mentioned above, there were significant mean scores except for emotion in the community ambulators compared with the others. CONCLUSIONS: The gait speed was significantly correlated with the physical domains of the QOL in stroke patients. The community ambulators had the highest QOL among the three groups.

Factors influencing home modification of stroke patients.

BACKGROUND: Home modification for stroke victims is often necessary to prevent falls and enable them to have a better quality of life. Up-to-date relationship between personal factors and home modifications in post-stroke patients has not been investigated. OBJECTIVE: To identify significant personal factors influencing the requirement for home modification in post-stroke patients. STUDY DESIGN: Prospective, analytical study. MATERIAL AND METHOD: Two hundred eighty one post-stroke patients were recruited from nine tertiary rehabilitation centers in Thailand. All patients received inpatient rehabilitation programs until either they reached the rehabilitation goals or registered two consecutive stable weeks as measured by their Barthel index score. Personal factors related to home modification were assessed at study entry, during hospital stay and at discharge. The correlation between personal factors and necessities of home modification in post-stroke patients were reported through univariate and multivariate modeling. RESULTS: The results of univariate analysis showed that a low Barthel index score (< or = 14/20) (at baseline and discharge), low Brunnstrom stage of arm or leg (< or = IV/VI) at baseline, and intolerance to intensive rehabilitation programs (< 3 hr/day) indicated a necessity for modifications in the patient's home (p < 0.05). The results of multivariate modeling showed that a low Barthel index score (at baseline and discharge), and intolerance to intensive rehabilitation were significant predictors of a requirement for home modification (p < 0.05). CONCLUSION: A low level of physical functioning and intolerance to intensive rehabilitation are significant predictors for the necessity of home modifications in stroke victims.

Comparing the effects of rehabilitation swallowing therapy vs. neuromuscular electrical stimulation therapy among stroke patients with persistent pharyngeal dysphagia: a randomized controlled study.

BACKGROUND: Dysphagia after stroke is associated with increased mortality, higher dependence, and longer hospitalization. Different therapeutic strategies have been introduced to improve swallowing impairment. There are no current studies that compare rehabilitation swallowing therapy (RST) and neuromuscular electrical stimulation therapy (NMES). OBJECTIVE: To compare treatment outcomes between RST and NMES intervention in stroke patients with pharyngeal dysphagia. STUDY DESIGN: A randomized controlled study. MATERIAL AND METHOD: Twenty-three stroke patients with persistent pharyngeal dysphagia (RST 11, NMES 12) were enrolled in the present study. The subjects received 60 minutes of either RST or NMES treatment for five consecutive days, had two days off and then five more consecutive days of treatment for a four-week period or until they reached functional oral intake scale (FOIS) level 7. The outcome measures assessed were change in FOIS, complications related to the treatment and number of therapy sessions. RESULTS: There were no significant differences in the stroke characteristics and the VFSS results between the two groups. At the end of treatment, the average numbers of therapy sessions per subject in the RST and NMES groups were 18.36 +/- 3.23 and 17.25 +/- 5.64, respectively, a non-significant difference. Average changes in FOIS scores were 2.46 +/- 1.04 for the RST group and 3.17 +/- 1.27 for the NMES group, statistically significant at p < 0.001. No complications were observed in either group. CONCLUSION: While both RST and NMES therapy showed a positive effect in the treatment of persistent dysphagia in stroke patients, NMES was significantly superior.
