On April 1, 2005, Olga Kilkens defended her dissertation entitled:
Manual wheelchair skill performance of persons with spinal cord injuries
Summary
The majority of persons with
spinal cord injuries (SCI) will be dependent on a manual wheelchair for their
mobility for the rest of their lives. The mastering of wheelchair skills will
enhance their independence and participation in daily life, and the actual
training of these skills therefore is a vital part of the inpatient
rehabilitation process. Although wheelchair skill performance is seen as an
important aspect for independent mobility, daily functioning, and
participation, there is only little known about the development of wheelchair
skill performance in persons with SCI during and after inpatient
rehabilitation. Thereby, only little insight exists in the longitudinal
relationship between manual wheelchair skill performance and personal- and
lesion characteristics, secondary
Aims and research questions
The primary aims of the present study are 1) to assess the clinimetric qualities of the Wheelchair Circuit, 2) to evaluate the development of manual wheelchair skill performance during the inpatient rehabilitation of persons with SCI, and to identify factors that affect this process, and 3) to study the relationship between manual wheelchair skill performance and participation in persons with SCI after discharge from inpatient rehabilitation.
The main research questions of this thesis are:
-
Is the Wheelchair Circuit a reliable, valid and responsive test to assess wheelchair skill performance?
-
How does manual wheelchair skill performance develop during inpatient rehabilitation of persons with acute SCI?
-
Is the development of manual wheelchair skill performance related to personal- and lesion characteristics, secondary complications, and physical capacity?
-
Is there a relationship between manual wheelchair skill performance and participation in persons with SCI, 1-year after discharge from clinical rehabilitation.

Results
Chapter 2 reports on a systematic review of wheelchair skills tests that are available in the literature. The search resulted in 24 different wheelchair skills tests that showed large variation in the skills that were included, and the outcome measures that were used. The clinimetric properties of only two tests were adequately investigated. The main conclusion of the review was that, at the start of this study, there was no standard test to measure wheelchair skill performance.
In Chapter 3 the Wheelchair Circuit, the test to assess manual wheelchair skill performance that was developed in this study is described, and the reliability of the Wheelchair Circuit is investigated. A convenience sample of persons with SCI, who were all in the final stage of their inpatient rehabilitation, performed the Wheelchair Circuit on three different occasions, and the measurements were conducted by two different raters. The results showed that the overall inter- and Intra-rater reliability of the Wheelchair Circuit is good.
Chapter 4 demonstrates that the Wheelchair Circuit is a valid and responsive instrument for measuring manual wheelchair mobility in persons with SCI.
Chapter 5
illustrates that during
inpatient SCI rehabilitation the scores of the Wheelchair Circuit
significantly improve, with the largest improvement occurring
during
the first three months. The development of wheelchair skill performance is
significantly influenced by age and lesion level. Older persons and persons
with tetraplegia have lower scores on the Wheelchair Circuit than younger
persons and persons with paraplegia.
Age and Body Mass
Index (BMI) are the most important variables to predict the scores of the
Wheelchair Circuit at the time of discharge. At the end of their inpatient
rehabilitation, older persons, and persons with a higher BMI will have lower
scores on the Wheelchair Circuit than younger persons and persons with a lower
BMI.
Chapter 6 shows that upper extremity muscle force and peak power output are important parameters for the development of wheelchair skill performance during inpatient rehabilitation. Persons with higher upper extremity muscle force and higher peak power output will have higher scores on the Wheelchair Circuit than persons with lower upper extremity muscle force and lower peak power output.
Chapter 7 shows that in persons with SCI, one year after discharge from inpatient rehabilitation, manual wheelchair skill performance is positively related to participation. This association remains significant when demographic variables and lesion characteristics are taken into account. In this study participation was assessed with the social dimension of the 68-item Sickness Impact Profile (SIP68).
Conclusions and recommendations
The Wheelchair Circuit is a
reliable, valid and responsive instrument to assess manual wheelchair mobility
in persons with SCI. The Wheelchair Circuit is a compact measurement, which is
convenient to perform. The scoring system is uncomplicated, easy to interpret,
and provides information on several aspects of 
wheelchair
skill performance. During the Inpatient rehabilitation, older persons and
persons with tetraplegia reach a lower level of wheelchair skill performance
than younger persons and persons with paraplegia. In future research it can be
investigated whether increasing the duration and/or frequency of wheelchair
skill training in older persons and in persons with a tetraplegia is useful to
reduce the adverse position these persons have concerning wheelchair skill
performance. There is a positive relation between the development of
wheelchair skill performance, peak power output, and upper body muscle
strength during the rehabilitation of persons with SCI. From this it is
concluded that, in order to optimize the development of wheelchair skill
performance, attention should be directed towards manual wheelchair exercise
training and strength training of the upper body muscle groups.
In persons with SCI, manual wheelchair skill performance is positively associated to participation one year after discharge from inpatient rehabilitation. To stimulate the level of participation after discharge it is important to pay extra attention to training and therapy aimed at achieving an optimal level of wheelchair skill performance during the inpatient rehabilitation period. Furthermore, persons should be stimulated to maintain their wheelchair skills after discharge from inpatient rehabilitation.
