Independent Wheelchair Transfers in the Built Environment: How Transfer Setup Impacts Performance Phase 2: Final Report

Protocol A Heights Obtained

The highest and lowest obtained transfers were compared for the participants that were tested at HERL (n=31) and the participants that were tested at the NDVSWC. The transfer heights obtained in protocol A for both sample groups can be seen in tables E4 and E5.

Table E4 Alternative Text Description: This table shows the attainable height percentiles for Protocol A minimum height transfers. Participants are divided into three groups in column one: participants tested at HERL, participants tested at the NDVWSC, and all participants. Columns two through six show the transfer heights for 5th, 25th, 50th, 75th, and 95th for each subset of participants. HERL participants tended to be able to transfer lower than NDVWSC participants. They attained lower heights in the 25th and 50th percentiles. The 5th, 75th, and 95th percentiles are equal for all groups.

Data shown in inches

For the minimum height transfer, the participants tested at HERL transferred about 1.4" lower on average than the participants tested at the NDVWSC.  The upper 95th percentile transfer heights were 3" higher for the NDVWSC than the HERL group for the maximum height transfer.
