Outcome measures
Primary outcome
Test: time of execution of the tests tasks and the scores of these tasks in
Index of Functionality.
Training:
Movement kinematics: movement reach time, movement grasp time, velocity of the
reach, peak velocity of the reach, symmetry of the velocity profile, hand
aperture, plateau phase in the hand aperture, velocity of hand opening and
closing, and the timing between the reach and the grasp movement;
Applied grip force;
EMG-signals of the extensors and flexors of the wrist: maximum value and number
of peaks
the pattern of the gaze of the participants: the sequence in which the objects
are fixated during a trial
Secondary outcome
Analysis of the videos recorded during the occupational therapy
Analysis of the daily diary in which the patients wrote down how often they
used their prosthesis during daily life and in which way they used their
prosthesis
Background summary
People with an upper extremity amputation often choose to have fitted a
prosthesis to restore the functionality for as best as possible, but the
rejection rate of prosthetic devices is high, mainly due to a low degree of
functional use (Biddis and Chau, 2007; Dudkiewicz et al., 2004; Kyberd et al.,
1998; Plettenburg, 2002). This functional use can be enhanced by training
(Carter, Torrance and Merry, 1969; Lake, 1997; Weeks, Anderson and Wallace,
2003). We expect that by enhancing the functional use through training, this
raises the overall use of prostheses. The training currently given by
rehabilitation centre is not evidence-based, but mainly based on own
experiences. Therefore, the overall aim of our project is to develop an
evidence-based training protocol for upper extremity prostheses, where we focus
in particular on myoelectric prostheses.
But before an evidence-based training program can be developed, we first have
to know how people learn to use their prosthesis. Therefore, the natural
learning processes during learning have to be determined. Describing the
changes in movement characteristics over learning gives us hints as to where we
can focus on in developing the training protocol.
Study objective
To measure the natural learning processes that take place while learning to use
a myoelectric prosthesis. The second objective is to compare the results with a
study of the learning processes in able-bodied participants who learn to use a
myoelectric prosthetic simulator
Study design
Case studies
Intervention
Next to the regular occupational therapy the patients receive in the UMCG, they
train during 5 sessions also in the laboratory. During these sessions they
train direct grasping, indirect grasping and fixating with their prosthesis.
The training will be used to register the improvements in the use of the
prosthesis.
Study burden and risks
The experiment is non-invasive. During 5 laboratory sessions, embedded in the
regular occupational therapy, the improvements of the patients will me
measured. The risks associated with participation can be considered negligible.
