Measurement Characteristics and Clinical Utility of the Spinal Cord Independence Measure-III Among Individuals With Spinal Cord Injury

Changes in functional independence after inpatient rehabilitation in patients with spinal cord injury: A simultaneous evaluation of prognostic factors

OBJECTIVE

This study aimed to investigate the improvements of functional independence following inpatient rehabilitation and compare those improvements between different levels and severities of Spinal Cord Injury (SCI). Prognostic factors affecting the patient's outcomes were also studied.

SETTINGS

Rofeideh Rehabilitation Hospital.

OUTCOME MEASURES

Spinal Cord Independence Measure version III (SCIM III), and Functional Independence Measure (FIM).

METHOD

In this retrospective cohort study, 180 patients with SCI were enrolled to record their functional independence upon admission and discharge, and the changes were compared between different levels and severities of injury using non-parametric tests. The prognostic factors of outcomes were studied by generalized estimating equation (GEE) analysis.

RESULTS

The independence changes were significant for all the severities (American Spinal Injury Association Impairment Scale (AIS)) and levels of injury except for the patients with AIS A and B at upper cervical levels (P < 0.05). The level of injury, AIS, Length of Stay (LOS), and pressure ulcer had a significant prognostic value on patient's outcomes. Furthermore, there was a significant difference between different levels of injury with the same AIS grade in functional improvement (P < 0.05), while there was a significant difference between AIS groups with the same level of injury only at upper and middle cervical lesions (P < 0.05).

CONCLUSION

Recording the values of functional independence before and after rehabilitation in individuals with SCI can help clinicians approximately expect the outcomes of future patients. Moreover, a deeper study of the prognostic factors can provide a more logical expectation of rehabilitation outcomes.

Reference Values and Cutoff Scores of the Spinal Cord Independence Measure III to Determine Independence for Wheelchair Users and Ambulatory Individuals With Spinal Cord Injury

OBJECTIVE

To establish the reference values and optimal cutoff scores of the Spinal Cord Independence Measure Version III (SCIM III) to indicate independence of wheelchair users (WU) and ambulatory (AM) individuals with spinal cord injury (SCI).

DESIGN

A cross-sectional study.

SETTING

Tertiary rehabilitation center and communities.

PARTICIPANTS

A total of 309 (168 WU and 141 AM) participants with SCI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

SCIM III scores.

RESULTS

Participants with greater levels of independence had significantly higher SCIM III scores, both total and subitem scores (P<.05). The SCIM III scores of ≥55 and ≥75 were optimal indicators of modified independence in WU and AM individuals, respectively (sensitivity and specificity >93%, AUC>.95). In addition, scores of 90 were proved to be excellent indicators for independence of AM individuals (sensitivity 94%, specificity 100%, AUC=.99).

CONCLUSIONS

The present findings provide the reference values of SCIM III scores covering WU and AM individuals with SCI at various levels of independence as well as optimal cutoff scores to indicate independence of these individuals. These data can be used as standard criteria for data comparison with patients' ability, and target functional values for individuals with SCI in clinical-, community-, and home-based settings.

Reliability and concurrent validity of the Spinal Cord Independence Measure III among rehabilitation professionals

Study design

A cross-sectional design.

Objectives

To investigate rater reliability of the Spinal Cord Independence Measure or SCIM III among rehabilitation professionals, along with the concurrent validity of the tool as compared to standard measures covering wheelchair users (WU) and ambulatory (AM) individuals with spinal cord injury (SCI).

Setting

A tertiary rehabilitation center and communities.

Methods

Eighty-two participants with SCI (39 WU and 43 AM individuals) were assessed using SCIM III items. The data of first 30 participants were video recorded for rater reliability assessments by seven rehabilitation professionals, including nurses, occupational therapists, and physical therapists (one novice and one experienced rater for each professional). All participants were also assessed using standard measures to verify concurrent validity of SCIM III by an experienced rater.

Results

The SCIM III showed excellent intra-rater and inter-rater reliability among rehabilitation professionals when analyzed for overall items (intraclass correlation coefficient (ICC) >0.90) and separately for each subscale (kappa values >0.80). The total SCIM III of WU and the mobility scores of AM participants showed significant correlation with standard measures for muscle strength, limit of stability, balance control, functional endurance, and walking ability (r_s = 0.343–0.779; p < 0.05).

Conclusions

The present findings extend clinical benefit and confirm the use of SCIM III interchangeably among rehabilitation professionals after they have been adequately trained. The findings are important for community-based rehabilitation and home healthcare services, especially during the coronavirus (COVID-19) pandemic, when hospital beds and in-patient services are limited for individuals with SCI.

Functional outcome following inpatient rehabilitation among individuals with complete spinal cord injury in Nepal

STUDY DESIGN

Descriptive study.

OBJECTIVES

To describe functional outcomes using Spinal Cord Independence Measure III (SCIM III) following inpatient rehabilitation among individuals with complete spinal cord injury (SCI) in the low-income setting of Nepal; to evaluate functional changes from rehabilitation admission to discharge and to compare functional outcomes between neurological levels of injury (NLI) at discharge.

SETTING

Spinal Injury Rehabilitation Centre (SIRC), Kavrepalanchowk, Nepal.

METHODS

We present data of all individuals with complete SCI who completed rehabilitation at SIRC in 2017. Data collected included: demographics, aetiology, neurological assessment, admission/discharge SCIM III scores, and length of stay. Data were analyzed using descriptive statistics. Pre/post-SCIM III scores were analyzed using Related-Samples Wilcoxon signed-rank test. Comparative analysis between NLIs was done using the Kruskal Wallis ANOVA test followed by pairwise Mann-Whitney U tests.

RESULTS

Ninety-six individuals were included. Mean (SD) age was 33.5 (14.2) years, with a male/female ratio of 3.4:1. Median admission and discharge total SCIM III scores for cervical, thoracic and lumbosacral levels were 10 and 21, 16 and 61, and 41 and 79.5, respectively. Median total SCIM III score change between admission and discharge were 11 (p = 0.003), 43 (p < 0.001) and 40 (p = 0.068) for cervical, thoracic and lumbar groups, respectively.

CONCLUSIONS

This study is the first of its kind to describe functional outcomes among individuals with complete SCI in the low-income setting of Nepal. All SCI groups showed a positive trend in SCIM III from admission to discharge, with improvements reaching statistical significance among groups with cervical and thoracic NLIs.
