Spinal Cord Injury Rehabilitation Biomechanics

Simple Explanation

This study explores methods to better assess seated balance in individuals with spinal cord injuries (SCI). The ability to maintain seated balance is crucial for independence in daily activities. The researchers adapted a computerized pressure-plate system, typically used for standing balance, to evaluate seated balance. This system, called posturography, provides objective measurements of balance and stability. The study compares the adapted posturography system with standard clinical tests like the Berg Balance Scale and the modified functional reach test to see which method is more effective for assessing seated balance deficits in SCI patients.

Study Duration

Not specified

Participants

7 able-bodied volunteers, 7 participants with chronic motor-complete thoracic SCI

Evidence Level

Cross-sectional observational study

Key Findings

1
Seated posturography showed a stronger correlation with the neurological level of the spinal cord lesion compared to the routinely used clinical tests.
2
Dynamic seated balance tests, such as the Limits of Stability (LOS) test, were more sensitive to SCI than static balance tests.
3
The seated portion of the Berg Balance Scale (BBS) exhibited a ceiling effect, making it difficult to differentiate between able-bodied individuals and those with SCI.

Research Summary

The study adapted a computerized posturography system to assess seated balance in individuals with spinal cord injury (SCI) and compared it with traditional clinical balance tests. The results indicated that seated posturography is more sensitive to the level of spinal cord lesion and provides a more objective measure of seated balance compared to the Berg Balance Scale and modified functional reach test. The study concludes that seated posturography represents a promising outcome measure for evaluating functional changes in response to rehabilitation interventions for individuals with paralysis.

Practical Implications

Improved Assessment

Seated posturography offers a more accurate and objective method for assessing seated balance deficits in individuals with SCI compared to traditional clinical tests.

Targeted Rehabilitation

The detailed breakdown of balance function provided by posturography can help therapists focus on specific deficiencies and tailor rehabilitation interventions accordingly.

Outcome Measurement

Seated posturography can be used as a sensitive outcome measure to track functional changes in response to various rehabilitation interventions in individuals with paralysis.

Study Limitations

1
The study involved a small number of subjects, which limits the ability to make definitive conclusions.
2
Some participants were assessed after the initiation of an exoskeletal gait training program, which represents a confounding factor.
3
The study's experience with individuals with motor-complete thoracic SCI does not allow generalizing the results to individuals with incomplete or cervical injuries.
