Impact of different forms of activity-based recovery training on bladder, bowel and sexual function following spinal cord injury

Simple Explanation

This study investigates whether the benefits of locomotor training (LT) on bladder, bowel, and sexual function after spinal cord injury (SCI) are due to weight-bearing or exercise in general. The study compared stand training (weight-bearing) and arm crank ergometry (non-weight-bearing exercise) to previously published locomotor training data. The results suggest that exercise in general may contribute to the lowering of bladder pressure, but task-specific stepping is required to maximize benefits for bladder and bowel function.

Study Duration
Not specified
Participants
22 males and females with spinal cord injury (ASIA Impairment Scale grades of A-D)
Evidence Level
Prospective cohort study; pilot trial with small sample size

Key Findings

  • 1
    Stand training alone did not improve pelvic organ functions after spinal cord injury.
  • 2
    Non-weight bearing exercise (arm crank ergometry) showed a significant decrease in bladder pressure and limited improvement in compliance.
  • 3
    Questionnaires revealed profound bowel dysfunction and marked deficits in sexual function pre-training, with no significant differences post-training for either stand or arm crank exercise.

Research Summary

This study investigated the impact of different forms of activity-based recovery training on bladder, bowel, and sexual function following spinal cord injury (SCI). The study compared stand training and non-weight bearing arm crank ergometry with previously published locomotor training data to determine the potential contributors toward the locomotor training benefits on urogenital/bowel function. The results suggest that exercise in general may contribute to the lowering of bladder pressure, but task-specific stepping is required to maximize activity-based recovery training benefits for storage and emptying related functions.

Practical Implications

Rehabilitation Strategies

Task-specific stepping should be prioritized in activity-based recovery training to maximize benefits for bladder and bowel function after SCI.

Home Exercise

Upper extremity training at home can reduce elevated bladder pressure, beneficial to the SCI population.

Further Research

Future mechanistic studies should focus on the sensory inputs derived from stepping and their activation of lumbosacral networks involved in bladder and bowel control.

Study Limitations

  • 1
    Small sample size
  • 2
    Potential lack of sensitivity of bowel and sexual function questionnaires
  • 3
    Potential physiological changes in colonic and rectal activity
