Participants: 174 parents of CWD (95 of them were parents
of children with physical impairment (PI), 51 of hearing
impairment (HI) and 28 of children with visual impairment
(VI)) attending a special school for the physically disabled,
in Thohoyandou, Limpopo Province of South Africa.
Methods: Qualitative and quantitative approaches were
used in this study. With focus group and survey designs
respectively. The contents of the research instrument were
developed through focus group discussions with parents of
children with physical disabilities. Information obtained also
supplemented data gathered from the survey. This also provided
insight into the factors that influenced parents attitudes
to CWD.
Analysis: The content of the focus group was recorded with
an audiotape and later transcribed verbatim. These were later
coded into themes. While Descriptive Chi square statistics
were used to analysed the quantitative data with the help of
the SPSS (This is presented else where).
Results: This study revealed that the majority of the parents
of CWD were unskilled and poor women. Parents were
found to demonstrate negative attitudes to their children with
disabilities. Parents are usually not able to obtain good livelihoods
because they are not trained. They are not educated
because they have to stay at home to care for their CWD.
Parents suggested that the grants from government should
be increased and converted to loans so that they could use
the money in starting small business under the supervision of
a unit that provides the loan until such a time that they are
self-reliant and economically independent.
Conclusions: Parental attitudes to their CWD were found to
be poor. This might have been as a result of inadequate knowledge
of their child’s physical disability. Parental responses on
the ability of their CWD to integrate in the larger society was
as result of ignorance about the ability of the CWD to reach
his/her full potential or of an over-protective attitude towards
the CWD. Disability-specific education should therefore be
provided to all parents and members of the community. It
is also recommended that parents of CWD be educated and
included in all matters that concern CWD at all levels of
governance and the rural areas in particular.
Implications: This study attempts to fill the gap by focusing
on the attitudes of parents towards CWD in the African context
(in this case, the Venda-speaking people). This data may
be useful in therapy, care or rehabilitation of children with
physical disabilities including counselling of their parents.

VALIDITY OF THE HAND-HELD DYNAMOMETRY

MEASURING MAXIMAL ISOMETRIC KNEE
EXTENSION STRENGTH

Purpose: Test results of the hand-held dynamometer can be
influenced by factors such as the examiner’s strength, the
subject’s stabilization and the sensitivity of the dynamometer.
The belt-resisted method (BR) was developed to eliminate
the examiner’s need to apply force to the subject, and high
reliability of this method was established. However, the measured
strength by the BR might be lower than that measured
by the stationary isometric dynamometry (ID), because during
the BR the subject was not stabilized. The purpose of this
study was to determine the validity of the BR compared to
the ID in healthy adults.
Relevance: The BR is a small and convenient equipment
compare to the ID. In order for the BR to be a useful clinical
tool, establishing its validity is essential.
Participants: Forty-eight healthy adults (23 men, 25 women)
from 21 to 62 years of age participated in this study. Ninetytwo
legs were measured, because 4 legs with pain were
excluded.
Methods: Maximal isometric knee extension strength was
measured by the BR and the ID in the sitting position. During
the BR subjects sat on the edge of a bed without stabilization
of the body, and the dynamometer pad was fixed on the
lower leg by the belt, which was connected to the foot of
the bed. During the ID subjects were seated while the lower
trunk, pelvis and thigh were stabilized using straps. In both
of the BR and the ID measurements, the dynamometer pad
was placed on the anterior surface of the lower leg, approximately
proximal to the ankle joint. The subject performed
three 5-second maximum isometric contractions, with a 30second
rest period between contractions. All measurements
were performed by the same physical therapist.
Analysis: SPSS Version 11.0 was used for all statistical analyses.
The maximal strength from 3 times measurements was
used in analysis. For comparisons between the BR and the ID,
Wilcoxon signed rank test was used. Relationship between
two measurements was assessed by Spearman’s rank correlation
coefficient. Bland & Altman plots were used to visualize
the difference between measurements against the corresponding
mean of the two measurements for each subject. A p value
of 0.05 was used for statistical significance.
Results: The BR’s strength was significantly lower than
the ID (p < 0.05); average difference of two measurements
for BR decreased; mean −0.8 kg (95%CI = −6.8 to 5.2 kg).
