Outcome measures
Primary outcome
The main study parameter is muscle activity pattern in daily life, expressed as
two sided low back SEMG, measured using a belt with SEMG electrodes.
Secondary outcome
To obtain information of the composition of the study groups several
questionnaires are used. Following aspects are determined:
For both groups: Demographics, self-perceived activity level.
For the patient group: Fear of movement, coping strategies, disability level,
pain intensity.
Background summary
Despite extensive research, the etiology of chronic low back pain (CLBP)
remains largely unknown. Musculoskeletal and biomechanical factors in the
etiology and maintenance of CLBP have been investigated using surface
electromyography (SEMG). All reported SEMG studies are based on laboratory
experiments. These studies have proven that the muscle activity in CLRP
patients is different as compared to healthy subjects. However, muscle
activation characteristics during laboratory tests might be different from
those in a daily life setting. The long term muscle activation pattern may
provide information which cannot be obtained in laboratory experiments. To gain
insight in the long term muscle activation patterns, it is necessary to measure
the muscle activation during daily activities. In the present explorative
study the low back muscle activity patterns during daily activities will be
determined in CLBP patients and in pain free subjects. The results of this
study may provide useful information for further research investigating
abnormal muscle activity patterns in CLBP and for research designing treatment
methods for CLBP patients. For the purpose of this study a belt with integrated
electrodes has been developed enabling ambulant registration of low back muscle
activity.
Study objective
The primary objective of this study is to gain more insight in the muscle
activation patterns of low back muscles during daily living in chronic low back
patients and in pain free subjects.
Study design
A cross-sectional study case-control study will be performed to investigate the
research questions.
Study burden and risks
The participants are not exposed to any risks. The laboratory exercises are
safe and non intensive. The long term measurements are safe but discomfort may
be caused by the belt and electrodes. The long period of skin contact of the
electrodes and the conductance gel may cause some skin irritation. Due to
tension of the belt around the low back and abdomen, this may somewhat give a
corset-like feeling. The complaints disappear usually within a few minutes
after removal of the belt.
The subjects are required to fill out questionnaires during the visit at RRD.
The number of questions for patients and pain free subjects is 117 and 19,
respectively.
All questionnaires are validated and modifications may result in that the given
answers are unusable. The relative large amount of questions in the
questionnaire for patients are required to obtain information about the nature
of the back complaints. This information is essential for the scope of this
study.
During the long term measurements the subjects are required to indicate their
activities in a diary. The subjects are drawn attention to the possibility to
skip parts of the diary for privacy reasons.
