Outcome measures
Primary outcome
Ball circumference: the narrowest circumference measure around ball width and
upper side foot.
Secondary outcome
1 Other foot structure variables, such as a) ball width, b) low instep, c) high
instep and d) heel instep size , standing barefoot (loaded condition)
2. The presence of foot complaints using a questionnaire with multiple choice
answers and open answers
3. Variables for pressure distribibution under the foot in six different
regions under the foot: a) mean pressure, b) peak pressure, c) contact area and
d) force-time integrals of the foot during stance and walking
4. Centre of pressure during stance (barefoot and with participants' own shoes
and shoes provided by the UMCG): a) location in antero-posterio direction
[percentage of total standlength], b) the absolute displacement of the COP in
antero-posterior and medio-lateral direction [mm] c) the velocity of the
displacement of the COP in antero-posterior and medio-lateral direction [m/s]
d) The total discplacement of the COP [mm]
5. The fit of shoes: a) Determine the incidence of well-fitting shoes in each
age-group [yes/no] and the absolute differences between foot structure
measurements and last measurements, which are currently used by shoe
manufacturers.
Background summary
The prevalence of falls increases with age. A perturbed balance, due to
ill-fitting shoes, is one of the leading causes of falls in healthy ageing
people. As a consequence, also foot complaints may arise due to ill-fitting
shoes.. Clinical practice gives the impression that age-related changes in
foot-structure and plantar pressure distribution are present. However, shoe-fit
of off-the-shelf shoes is based on the *average* foot structure of adult people
and thus neglects the possible effects of age on foot structure. Therefore, it
is of increasing interest to gather information about the development of foot
structure, foot complaints and pressure distribution over age in order to
analyze possible age-related differences. When differences in foot structure,
foot pain and pressure distribution between age-groups exist, the results can
be used to adapt shoe lasts in order to develop shoes specifically for
age-related changes in women.
Study objective
To gather information about the development of 1. foot structure, 2. foot
complaints, 3. plantar pressure distribution and 4. centre of pressure
progression in feet over time in ageing women. 5. To determine the fit of shoes
based on currently used last by shoe tecnicians, 6. To determine the effect of
wearing solid, standard shoes on the plantar pressure distribution and center
of pressure and 7. To determine the relationship between foot structure, foot
complaints, plantar pressure distribution and center of pressure.
Statistically significant results may result in the development of
better-fitting shoes by shoe technicians, according to age,
Study design
It is a cross-sectional observational study
Study burden and risks
The measurements will be conducted once (approx. one and a half hour) at the
UMCG, in the motion laboratory of the department of Rehabilitationmedicine. No
risks or burden are associated with the measurements, other than those
encountered in daily life during standing and walking. Therefore, risks and
burden are negligible. There are no invasive measurements of intervention
methods (medicine). In addition, there are no adverse effects.
Participants are asked to fill out a questionnaire about foot complaints.
Furthermore, geometry measures are made using tape measure and a 3D geomety
footscan while standing.
Plantar pressure distribution and centre of pressure are measured using
removable insoles while wearing shoes during standing and walking (Novel Pedar
system). It is a leightweight and mobile system and therefore does nog cause
any harm to the subjects. Women are included in this research because of our
cooperation with a shoe manufacturer which specializes in women's shoes and the
fact that women have a higher risk of falling and experience more foot
complaints.
To determine the sensibility of the foot sole, the Semmes Weinstein test will
be performed. Nylon monofilaments will be used. Sensibility can be decreased in
elderly people or diabetic patients. Consequently, also perception of foot
complaints or pain of the foot decrease. This test is not harmful for the
participants and lasts for only a few seconds.
