Comfort and stability of wheelchair backrests according to the TAWC (tool for assessing wheelchair discomfort)

Disabil Rehabil Assist Technol, 2016 · DOI: 10.3109/17483107.2014.938365 · Published: May 1, 2016

Simple Explanation

This study aimed to compare the comfort levels reported by wheelchair users with different types of backrests (sling vs. rigid) using the Tool for Assessing Wheelchair disComfort (TAWC). The study surveyed 131 wheelchair users and found a trend suggesting that rigid backrests were less comfortable compared to sling backrests, particularly among participants with tetraplegia. The results suggest that rigid backrests, despite potentially providing more support, may lead to higher discomfort due to suboptimal fit, adjustment, or individual preferences, especially for those with tetraplegia.

Study Duration

10 days

Participants

131 wheelchair users

Evidence Level

Cross-sectional study

Key Findings

1
The study found a trend suggesting that rigid backrests are less comfortable compared to sling backrests.
2
In a subgroup of participants with tetraplegia, the finding that rigid backrests were less comfortable was statistically significant.
3
The overall trend was for rigid backrest users to have more discomfort than sling users.

Research Summary

The study investigated the comfort levels of wheelchair users with different backrest types (sling vs. rigid) using the TAWC. Results indicated a trend of rigid backrests being less comfortable than sling backrests, with significant discomfort reported by rigid backrest users with tetraplegia. The study suggests that factors like suboptimal fit, adjustment, or user preferences may contribute to the higher discomfort ratings among rigid backrest users, especially those with tetraplegia.

Practical Implications

Need for Long-Term Discomfort Measure

There is a need for a specific measure to assess long-term seating discomfort in wheelchair users.

Improved Rigid Backrest Design

There is a need for the design and development of better rigid backrests that are both functional and comfortable.

Individualized Backrest Fitting

Proper fitting and adjustment of rigid backrests are crucial to ensure user comfort, particularly for individuals with tetraplegia.

Study Limitations

1
The study is limited by its sample size, which may have affected its power to detect statistically significant differences.
2
The TAWC may not be sensitive enough to detect differences in discomfort specifically related to the backrest.
3
The study did not collect data on the duration of backrest use, which could influence comfort ratings.
