Outcome measures
Primary outcome
The primary study parameter is the amount of EMG, with parameters relative
rEMG, amplitud (mV), frequency amount (Fmed) in Hz. These parameters will be
measured by surface and intramuscular EMG.
Secondary outcome
not applicable
Background summary
Non-specific lower backpain is a painsyndrome, however the exaclty cause is not
known. Probably there are several factors that contribute to this painsyndrom.
The last several years, people are interest to devide non-specific lower
backpain patients in different subgroups. Because these different subgroups
need probably different specific treatments. In regular treatment the most
attention focused on disbalans between back and belly muscles. The activity
pattern and power of mm. multifidi and m. obliquus abdominis can be measured by
electromyografy (EMG), intramuscular and surface EMG. There is a lack of
clarity how surface EMG and intramuscular EMG correlate in clinical tests in
healthy volunteers and non-specific lower backpain patients. This study will
controbute to create new knowlegde about EMG in back muscles in clinical tests
and improve diagnostics for physiotherapist in function and morfology of back
muscles in non-specific lower backpain patients.
Study objective
What is the correlation between intramuscular and surface EMG of the mm.
multifidi in different clinical tests in healthy subjects and non-specific
lower backpain patients?
Study design
cross sectional study design
Study burden and risks
The burden of the subjects are limited. Subjects will be measured once at the
clinical neurophysiology at the UMCG. This will be taken a maximum of one
houre. The risks that could be arise during the measurement: a local
intramuscular bleeding and/or a sensitive skin neuron could be hit by using
intramuscular EMG. This could result in extra pain during the measurement for
the subjects. These risks are minimalized, because the intramuscular EMG
measurements will performed by an experienced clinical neurophysiologist. The
advanced of participating in this study for the subjects is, they will
contribute to create more knowledge about to diagnostic non-specific lower
backpain patients in the physiotherapy. The subjects will get traveling
expenses and a cheque of 15 euros for participation in this study.
