Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be issued with a mouldable pen (designed at Unitec) to use for 8 weeks.
The researcher will show the participant how to mould the pen initially. It can then "set" into shape or be re-moulded if the participant wishes.
The pen has a latex exterior, the design of the internal contents are the intellectual property of the designer and Unitec Institute of Technology.
Participants are asked to use the pen as they would a normal pen and to note when they use it.
Intervention code [1] 290097 0
Treatment: Devices
Comparator / control treatment
Participants will be issued with a commercially available pen (the PenAgainTM) to use for 8 weeks. The PenAgainTM is available worldwide. It has a patented wishbone shaped design and has been ergonomically developed to fit to the contours of the hand. Use of this pen may help alleviate the symptoms of Writers Cramp, Carpal Tunnel Syndrome, Calluses, RSI, and Arthritis.

Outcomes
Primary outcome [1] 293021 0
Writing quality as measured by the Handwriting Assessment Battery for adults (McCluskey & Lannin, 2003).
Timepoint [1] 293021 0
Baseline and 8 weeks after intervention commencement.
Secondary outcome [1] 310169 0
Modified Health Assessment Questionnaire - to measure quality of life for those with arthritis.
Timepoint [1] 310169 0
Baseline and 8 weeks after intervention commencement.
Secondary outcome [2] 310170 0
Count of joints affected by osteoarthritis of the hand. Hands will be examined for the occurrence of bony enlargements (1= present, 0= absent) and will be calculated as a summary of signs in both hands (range 0 to 30). The American College of Rheumatology criteria (Altman et al., 1990) will also be used as a diagnosis confirmation of hand osteoarthritis.
Timepoint [2] 310170 0
Baseline and 8 weeks after intervention commencement.
Secondary outcome [3] 310171 0
Australian/Canadian hand index (AUSCAN) - self reported Likert scales for hand pain, stiffness and physical functioning.
Timepoint [3] 310171 0
Baseline and 8 weeks after intervention commencement.
Secondary outcome [4] 310172 0
Measure of Assistive Technology use scale- Likert scale assessing use of devices and 100mm VAS scale for comfort with assistive technology.
Timepoint [4] 310172 0
Baseline and 8 weeks after intervention commencement

Efficacy
Statistical methods / analysis
Using the Handwriting Assessment Battery for adults (HAB) legibility data from a pilot trial (by the same researcher) - baseline data from the writing aid was 76.5% accuracy (SD=13.9). A 15% change would require 24 people in each group, whereas a 20% changes would require 13 people in each group. Using HAB lower case writing data form the pilot study - baseline data from the writing-aid was 80.6% accuracy (SD=12.91). A 10% change would require 41 in each group, whereas a 15% change would require 18 people in each group. Taking these into account,a sample size of 40 people (20 per group) was chosen as being statistically justified and realistically attainable.

All analysis will be performed on an intention to treat basis and based on the aggregated data for each allocated group. Paired Student’s t-tests will be used to identify the differences at baseline and follow-up between the two pen allocation groups. Differences within the groups will also be analysed by paired samples Student’s t-tests. To account for differences in baseline the change from baseline in each group will be compared. Distributions will be examined for normality and parametric and non-parametric tests will be applied as required. In the case of data that are not normally distributed the Mann-Whitney test, which is suitable for independent samples, will be used. All of the endpoints will be continuous quantitative data.
