The Effect of a Wheelchair Skills Training Program on Acquisition of

Efficacy of a Wheelchair Skills Training Program at
Improving Community and Advanced Level
Wheelchair Skills in Manual Wheelchair Users
Sheena McCormack
PT 209/910
Introduction
•
1.7 million wheelchair/scooter users
• 90% use manual wheelchairs
(UCSF disability statistics center, 2014)
Hunt 2004 Cross-Sectional study 412 people with SCI who
use w/c >40hrs per week
○ 97% of manual w/c users had
customizable wheelchairs. Of those that
had non-customizable wheelchairs, majority
were people of color with less than high school
education and low-income status.

Measuring Wheelchair Skill
● Wheelchair Skills Test (Most recent version 4.2.2)
Indoor
• Transfers, removing footrests, etc.
Community
• Curbs, ramps, etc.
Advanced
• All involve the wheelie

The Wheelie
Definition: a rear pitch
force causes the front
caster wheels to leave the
support surface
Use: negotiating uneven
terrain, curbs, and
descending steep inclines

(Kirby, 2006)
Wheelchair Skills
↑ Scores on wheelchair skills
tests
↑ Life satisfaction,
community
participation, and
return to work
Scores obtained at time of discharge from acute rehab tend to remain constant one year later
(Hosseini 2012, Van Velsen 2012, Flies 2013).

Introduction
Clinical Problem
Many manual wheelchair users do not have community-level
wheelchair skills (navigating curbs, performing a wheelie, etc.)
which are important for being independent in the community
(Ganesh 2007, Kirby 2006, Hosseini 2012).
How do we train a skill?
• Principles of Motor learning/Neuroplasticity
▫ Use it or lose it
▫ Use it and improve it
▫
▫

Specificity

(Merzenich 1984, Merzenich 1978, Umphred 2013)
Wheelchair Skill Training Program
• Guidelines for instructors on
feedback (i.e. verbal cues) and
training schedules based on principles
of motor learning (specificity,
repetition, intensity, time)
• Each skill on the WST
• Gap: RCTs, No meta analysis
http://www.manfred-sauerstiftung.de/uploads/pics/mss_gz_rollstuhltraining1_01.jpg
Theoretical Construct
Standard rehab (low intensity/time/repetition)
Low acquisition of wheelchair skills which have
been correlated to QOL
Wheelchair skills training program (WSTP) is
intense, repetitive, and specific to wheelchair skills
WSTP + standard rehab may ↑ skill acquisition
Relevance to PT & Purpose
● Acute care, Rehab, Outpatient
● Functional training, assistive
device training, patient goals
● Community reintegration &
return to work
● Purpose: Guidance
http://www.manfred-sauer-stiftung.de/uploads/pics/mss_gz_rollstuhltraining1_01.jpg
Primary Question
● Do manual wheelchair users improve their capacity to
perform community and advanced-level wheelchair skills
after a high-level, focused wheelchair skills training program
as compared to treatment as usual?
P: Manual wheelchair users
I: Wheelchair Skills Training in high-level skills
C: No training
O: Wheelchair Skills Test (multiple versions)
Hypotheses & Expected Findings
Ho: Training in high-level wheelchair skills does not improve ability to
perform community-level wheelchair skills in manual wheelchair users
HA: Training in high-level wheelchair skills improves ability to perform
community-level wheelchair skills in manual wheelchair users
Expected findings:
● 3-10 primary articles, at least 1 with level 2b evidence or above.
● reject the null hypothesis
Inclusion/Exclusion Criteria
Inclusion

Hypotheses & Expected Findings
Ho: Training in high-level wheelchair skills does not improve ability to
perform community-level wheelchair skills in manual wheelchair users
HA: Training in high-level wheelchair skills improves ability to perform
community-level wheelchair skills in manual wheelchair users
…BUT this is not true for ALL skills
Limitations
•
•
•
•
•
Only 4, low quality RCTs
Small sample sizes
None performed in U.S.
Many from the same research group
Limited follow-up
Harm & Cost
● No injuries
● Routhier - 2 falls out of
wheelchair, 1 tip backward
during testing
● Precautions - Spotter strap
(MacPhee & Best),
helmets, gloves, intervene
when unsafe techniques
were observed
● Cost = additional 3-12 3060min sessions with
PT/OT, equipment
