Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be required to complete 3 x 15 mins of standard typing under three conditions applied to the dominant trapezius muscle (muscle on top of the shoulder): no taping; sham taping; inhibitory taping. For the inhibitory taping, a rigid tape will be applied from the anterior aspect of the mid clavicle across the body of the Upper Trapezius muscles to approximately the level of the seventh rib with a posterio-inferior force to bunch the Upper Trapezius muscle fibres. For sham taping, tape will be applied without tension on the same spot of the Upper Trapezius as the inhibitory taping. Activity of this muscle during the three typing conditions will be evaluated using surface electromyography (sEMG) (non-invasive). Participants will complete a baseline 15 minute typing task immediately prior to each 15 minute intervention period (i.e. 30 minutes typing in total).
Taping will be removed after 15mins of a typing task.
Wash-out period between the 3 x 15 min testing sessions will be 3 days at least.

Control group
Placebo

Outcomes
Primary outcome [1] 286280 0
The Amplitude Probability Distribution Function (APDF) of muscle activity of the upper and lower trapezius
This is calculated from data collected using sEMG.
Timepoint [1] 286280 0
during 15mins of a typing task before an intervention (ie, inhibition taping, sham taping or control) and during the intervention
The first 15 minute typing task will occur immediately prior to the 15 minute intervention period (i.e. 30 minutes typing in total).
Secondary outcome [1] 295501 0
The proportion of the APDF of the upper trapezius to that of the lower trapezius
This is calculated from data collected using sEMG.
Timepoint [1] 295501 0
Myoelectric data will be collected for 10sec prior to the intervention and then during the 15mins standard typing task and during each intervention (sham taping, inhibition taping and control).

Eligibility
Key inclusion criteria
Asymptomatic healthy individuals without any history of head, neck and shoulder pain or trauma for which the individuals have sought medical treatment
Minimum age
18 Years
Maximum age
60 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Individuals with contraindication for taping (eg, skin diseases), symptoms which may affect a typing task (eg, carpal tunnel syndrome, cervical radiculopathy, and neuromuscular disorders) or score of above 2 in the Neck Disability Index (NDI).

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Asymptomatic participants will be recruited via notices and flyers on university notice boards. Notices may also be placed on community notice boards in surrounding suburbs. The project will be advertised to students prior to lectures after having obtained the lecturers permission.
Participants will sign a consent form. Information on participants’ age, sex, relevant medical history, height and weight will then be collected. They will then complete two questionnaires, the NDI and a computer use questionnaire.
This study is a randomised cross-over design. Firstly, each participant will select one card from an envelope in which the order of the three interventions will be written (eg, Time 1: inhibition taping, Time 2: no tape, Time 3: sham taping). The participant gives this card to the attending researcher without viewing the contents. The envelope will contain 6 cards – corresponding to the number of possible combinations of the three conditions. The order of the intervention will be known to the therapist applying the tape only and the order of application will be blinded to each participant and the researcher undertaking the data analysis and collection.
