Effectiveness of a Community-Based Exercise Program for Ambulatory Individuals With Spinal Cord Injury: A Randomized Controlled Trial

Abstract

  • Objective: Evaluate the effectiveness of a community-based structured exercise program compared to usual care for enhancing physical, functional, and psychological outcomes in ambulatory individuals with spinal cord injury (SCI).

  • Design: Randomized controlled trial (RCT) comparing an exercise group to a usual care group.

  • Setting: One university-affiliated rehabilitation hospital.

  • Participants: 57 participants with chronic SCI who were able to walk more than 10 meters.

  • Interventions: 20-session supervised program over 8 weeks focused on flexibility, aerobic, and strengthening exercises for the exercise group.

  • Main Outcome Measures:

    • Primary Outcome: 6-minute walk test (6MWT).

    • Secondary Outcomes: EuroQol-5 Dimensions 5-Level (EQ-5D-5L), Spinal Cord Independence Measure III (SCIM III), Berg Balance Scale (BBS), Timed Up and Go (TUG), grip strength, 30-second sit-to-stand test (30-STS), sit and reach test, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), bioelectrical impedance analysis (BIA).

Results

  • Participants' Allocation:

    • Intervention Group: 36 participants.

    • Usual Care Group: 15 participants.

    • Demographics: 34 males, 17 females; average age 59.78 ± 13.19 years; 24 cervical, 17 thoracic, 8 lumbar, 2 sacral lesions; all participants had motor incomplete injuries.

  • Significant Improvements in the Exercise Group Compared to Usual Care Group:

    • 6MWT: Improvement of 49.80 m (95% CI, 13.04 - 86.55).

    • BBS Scores: Improvement of 3.50 (95% CI, 0.96 - 6.03).

    • 30-STS: Improvement of 2.38 (95% CI, 0.29 - 4.47).

    • Sit and Reach Test: Improvement of 3.89 cm (95% CI, 0.96 - 6.82).

  • Adherence Rate: High at 89.6%, indicating the feasibility of community exercise programs for this population.

  • Psychological and Quality-of-Life Measures: No significant changes noted in psychological and quality-of-life measures.

Conclusions

  • Community-based structured exercise programs are feasible and effective in improving walking capacity, balance, lower extremity strength, and flexibility in ambulatory individuals with SCI.

  • Implications for reducing socioeconomic burden and improving rehabilitation strategies post-hospital discharge.

Introduction

  • Spinal Cord Injury (SCI): Affects motor, sensory, and autonomic functions; leads to significant daily activity limitations, particularly in physical exercise.

  • As mortality rates have decreased, the socioeconomic burden related to survival and rehabilitation has increased.

  • Importance of Preventing Medical Complications: Regular physical activity is essential for reducing hospitalization and caregiver dependence, with economic impacts ranging as high as USD 290,000 - 435,000.

  • Guidelines: Canadian physical activity guidelines suggest at least 20 minutes of moderate to vigorous intensity aerobic activity twice a week and strength exercises for major muscle groups biweekly.

Previous Research

  • Various studies on community-based exercise programs for individuals with SCI show conflicting results due to varying demographics and settings.

  • Need for clinical evidence, especially in Korea, where community reintegration is often faced with limitations like insufficient resources.

Methods

Trial Design
  • Type: Parallel-group RCT comparing exercise program effectiveness.

  • Setting: Conducted at Pusan National University Yangsan Hospital.

  • Participants: Recruited based on strict eligibility criteria for SCI more than 6 months post-injury and age between 19-85 years.

Inclusion Criteria:
  • Chronic SCI (over 6 months), able to ambulate >10 m, sufficient arm mobility for exercises, residence at home, AIS grades C or D.

Exclusion Criteria:
  • Unable to follow protocols, uncontrolled medical conditions (e.g., hypertension, diabetes), or recent cardiovascular events.

Randomization and Sample Size
  • 57 participants recruited with a 2:1 allocation ratio to account for higher dropout rates expected in the exercise group; statistical power set at 0.8.

Intervention

  • Usual Care Group: Regular daily exercise and medical care.

  • Exercise Group: 20 sessions (3/week), focusing on personalized flexibility, aerobic, and strengthening exercises. Overseen by trained physical therapists.

    • Flexibility Exercises: 10 minutes, targeting major joints.

    • Aerobic Exercise: 20 minutes at RPE of 4-8, primarily using treadmills.

    • Strengthening Exercises: 3 sets of 10 repetitions, 50%-70% of 1 repetition maximum targeting major muscle groups.

Outcome Measures
  • Primary Outcome: 6MWT to measure aerobic endurance.

  • Secondary Measures: EQ-5D-5L, SCIM III, BBS, TUG, grip strength, 30-STS, SRT, BAI, BDI, BIA.

  • Assessment Schedule: Measures taken at baseline (0 weeks) and post-intervention (up to 12 weeks).

Safety Monitoring and Adherence Rate
  • Monitoring of adverse effects during the exercise program with specific safety parameters outlined.

  • Adherence rates measured by percentage of sessions completed.

Data Analysis
  • Statistical analysis using IBM SPSS software with significance level set at P < 0.05.

Results

Demographics and Statistics
  • Enrolment: 57 total (38 exercise, 19 usual care); data analysis included 36 in exercise, 15 in usual care.

  • Notable outcomes indicated significant improvements in physical measures.

Adverse Events
  • Adverse events included one participant experiencing hypoglycemia; overall exercise program deemed safe.

Satisfaction with Program
  • High levels of satisfaction across various metrics evaluated in satisfaction surveys post-program.

Discussion

  • Findings indicate significant improvement in physical functions due to structured exercise programs, while psychological measures did not reflect statistically significant changes.

  • Structured exercise programs are recommended for clinical and community settings to aid rehabilitation post-SCI.

Study Limitations

  • Generalizability limited to individuals with motor incomplete SCI; variations in baseline characteristics.

  • Challenges in measuring subjective intensity and comparing to previous trials; participants' disabilities varied.

Conclusions

  • Evidence supports effectiveness of community exercise programs, highlighting potential for broader application and addressing ongoing rehabilitation needs for SCI individuals in Korea.

  • Future Directions: Further exploration of long-term benefits, policy enhancements for resource access in the SCI community.

The article by Huh et al. evaluates the effectiveness of a community-based structured exercise program for ambulatory individuals with spinal cord injury (SCI). In a randomized controlled trial involving 57 participants, the exercise group (36 participants) underwent a supervised 20-session program focused on flexibility, aerobic, and strengthening exercises, while the usual care group (15 participants) continued with standard medical care. Significant improvements in physical outcomes were recorded in the exercise group, particularly in the 6-minute walk test (49.80 m improvement). Despite high adherence rates (89.6%), no substantial changes were noted in psychological measures. The findings suggest that community-based exercise programs can effectively enhance physical performance and are feasible for individuals with SCI, indicating potential for broader applications in rehabilitation strategies.
