Reliability of the Dynamic Gait Index in individuals with multiple sclerosis

McConvey J, Bennett SE. Reliability of the Dynamic Gait Index in individuals with multiple sclerosis.

Objectives

To determine if the Dynamic Gait Index (DGI) is a reliable tool for assessing balance in people with multiple sclerosis (MS) and to determine the validity of the DGI by using the 6.1-m timed walk.

Design

Instrument reliability test: physical therapists viewed a videotape of 10 subjects with MS performing the DGI and scored their gait by using DGI criteria. Two weeks after the first session, therapists’ viewed the videotape again and scored subjects’ gait to establish interrater reliability.

Setting

Hospital-based outpatient rehabilitation clinic.

Participants

Eleven physical therapists and 10 people with MS.

Interventions

Not applicable.

Main outcome measures

Total DGI scores and each of the 8 DGI items were compared between and within raters (physical therapists). Time to walk 6.1m was compared with the total DGI score to examine concurrent validity.

Results

Interrater reliability for total DGI scores was .983, with each of the 8 items ranging from .910 to .976 (intraclass correlation coefficient, P<.05). Intrarater reliability for total DGI scores ranged between .760 and .986 (Pearson bivariate analysis, P<.05). An inverse relationship of −.801 (Pearson bivariate analysis, P<.01) existed between the total DGI scores and the 6.1-m walk.

Conclusions

The DGI is a reliable functional assessment tool that correlated inversely with timed walk, showing its concurrent validity.

Reliability of the Dynamic Gait Index (Finnish version) in individuals with neurological disorders

Purpose: To produce a Finnish version of the Dynamic Gait Index (DGI) and establish its reliability in people with neurological disorders affecting balance. Method: A consecutive sample of 33 participants in inter-rater and 30 participants in intra-rater sample were tested. The DGI was administered in two testing sessions 1–2?h apart. Reliability was assessed with the intra-class correlation coefficient (ICC), Bland–Altman 95% limits of agreement, coefficient of reproducibility (CR), and standard error of the mean (SEM). Results: The instructions from the original DGI were preserved during the translation process with no need for cultural adaptations. The relative reliability of the total scores proved to be high in inter-rater (ICC?=?0.90) and intra-rater (ICC?=?0.91) testing. The relative reliability between single items varied from poor to high in inter-rater (r?=?0.57–0.96) and intra-rater (r?=?0.20–0.97) testing. Absolute reliability of the total score was high, and in single items, it varied similarly to relative reliability. The SEM was 1.2 points in inter-rater and 0.8 points in intra-rater testing. Conclusions: The Finnish version of DGI was produced and found to be a reliable tool for clinical testing of balance in neurological patients with balance disorder.

Implications for Rehabilitation

• The Dynamic Gait Index (DGI) is a promising test for the fall-risk evaluation, since it is a standardized tool for evaluating the quality of dynamic balance during walking and an individual’s ability to modify walking in different kinds of situations and dual tasks.

• In this study, the Finnish version of the DGI was produced and the total score was reliable. Thus, the Finnish DGI can be recommended for clinical testing in individuals with neurological diseases involving balance disorder.

     

Reliability of the dynamic gait index in people with vestibular disorders

OBJECTIVE: To examine the interrater reliability of the Dynamic Gait Index (DGI) when used with patients with vestibular disorders and with previously published instructions. DESIGN: Correlational study. SETTING: Outpatient physical therapy clinic. PARTICIPANTS: Subjects included 30 patients (age range, 27-88y) with vestibular disorders, who were referred for vestibular rehabilitation. INTERVENTIONS: Subjects' performance on the DGI was concurrently rated by 2 physical therapists experienced in vestibular rehabilitation to determine interrater reliability. MAIN OUTCOME MEASURES: Percentage agreement, kappa statistics, and the ratio of subject variability to total variability were calculated for individual DGI items. Kappa statistics for individual items were averaged to yield a composite kappa score of the DGI. Total DGI scores were evaluated for interrater reliability by using the Spearman rank-order correlation coefficient. RESULTS: Interrater reliability of individual DGI items varied from poor to excellent based on kappa values (kappa range,.35-1.00). Composite kappa values showed good overall interrater reliability (kappa=.64) of total DGI scores. The Spearman rho demonstrated excellent correlation (r=.95) between total DGI scores given concurrently by the 2 raters. CONCLUSION: DGI total scores, administered by using the published instructions, showed moderate interrater reliability with subjects with vestibular disorders. The DGI should be used with caution in this population at this time, because of the lack of strong reliability.     

Construct validity of the SF-12 in three different samples

Rationale, aims and objectives Studies have challenged the validity and underlying measurement model of the physical and mental component summary scores of the 36‐item Short‐Form Health Survey in, for example the elderly and people with neurological disorders. However, it is unclear to what extent these observations translate to physical and mental component summary scores derived from the 12‐item short form (SF‐12) of the 36‐item Short‐Form Health Survey. This study evaluated the construct validity of the SF‐12 in elderly people and people with Parkinson's disease (PD) and stroke. Methods SF‐12 data from a general elderly (aged 75+) population (n = 4278), people with PD (n = 159) and stroke survivors (n = 89) were analysed regarding data quality, reliability (coefficient alpha) and internal construct validity. The latter was assessed through item‐total correlations, exploratory and confirmatory factor analyses. Results Completeness of data was high (93–98.8%) and reliability was acceptable (0.78–0.85). Item‐total correlations argued against the suggested items‐to‐summary scores structure in all three samples. Exploratory factor analyses failed to support a two‐dimensional item structure among elderly and stroke survivors, and cross‐loadings of items were seen in all three samples. Confirmatory factor analyses showed lack of fit between empirical data and the proposed items‐to‐summary measures structure in all samples. Conclusions These observations challenge the validity and interpretability of SF‐12 scores among the elderly, people with PD and stroke survivors. The standard orthogonally weighted SF‐12 scoring algorithm is cautioned against. Instead, when the assumed two‐dimensional structure is supported in the data, oblique scoring algorithms appear preferable. Failure to consider basic scoring assumptions may yield misleading results.     

Reliability and validity of the dynamic gait index in persons with chronic stroke

Jonsdottir J, Cattaneo D. Reliability and validity of the Dynamic Gait Index in persons with chronic stroke.

Objective

To establish the test-retest and interrater reliability as well as the concurrent construct validity of the Dynamic Gait Index (DGI) as a measure for dynamic balance in people with chronic stroke.

Design

Cohort study.

Setting

Day hospital and ambulatory care at a rehabilitation center.

Participants

A consecutive sample of 25 participants, at least 3 months poststroke and able to walk at least 10m with or without a walking aid, participated in the study. Two independent raters rated performances on the DGI.

Interventions

Not applicable.

Main Outcome Measures

The DGI was administered in 2 testing sessions 3 days apart. In the second session, the participants were rated by 2 raters. Intraclass correlation coefficients (ICCs), model 2,1, and the Bland and Altman method were used to analyze total scores and item scores. Concurrent construct validity was tested by correlating results to the Berg Balance Scale, the timed walking test, the Timed Up & Go test, and the Activities-specific Balance Confidence Scale.

Results

ICCs for test-retest and interrater reliability of total scores were good (.96, .96, respectively) whereas reliability for single item scores was moderate to good (range, .55−.93). The hypotheses for concurrent construct validity were confirmed with all measures (range, .68−.83).

Conclusions

The DGI showed high reliability and showed evidence of concurrent validity with other balance and mobility scales. It is a useful clinical tool for evaluating dynamic balance in ambulatory people with chronic stroke.

Intra- and interrater reliability and agreement of the Danish version of the Dynamic Gait Index in older people with balance impairments

Jønsson LR, Kristensen MT, Tibaek S, Andersen CW, Juhl C. Intra- and interrater reliability and agreement of the Danish version of the Dynamic Gait Index in older people with balance impairments.

Objectives

To examine the intrarater and interrater reliability and agreement of the Danish version of the Dynamic Gait Index (DGI) in hospitalized and community-dwelling older people with balance impairments.

Design

Reliability study.

Setting

University hospital and outpatient rehabilitation.

Participants

A convenience sample of older people (≥65y); 24 subjects from a hospital and 24 from an outpatient rehabilitation center. All subjects had either 1 or more falls within the last year or balance impairments evaluated by a physical therapist.

Interventions

Not applicable.

Main Outcome Measures

All subjects carried out the DGI twice with a 1.5-hour interval. Each subject was rated by 3 physical therapists in the first attempt (1 for intrarater and 2 for interrater comparison) and by the intrarater in the second attempt, in both settings. The reliability was calculated using the intraclass correlation coefficient (ICC, 2.1), while agreement was calculated as the smallest real difference (SRD).

Results

The ICC for intrarater and interrater reliability of the total DGI was .90 and .92 at the hospital, while the SRD was 2.72 and 2.58 points, respectively. Correspondingly, the ICC for intrarater and interrater reliability of the total DGI at the rehabilitation center was .89 and .82, while the SRD was 3.49 and 3.99 points, respectively.

Conclusions

The intrarater and interrater reliability of the total DGI ranged from good to excellent in hospitalized and community-dwelling older people. Improvements of 3 and 4 DGI points for hospitalized and community-dwelling older people, respectively, should be regarded as a real change (with a 95% certainty).
