method aimed at obtaining information about community-based rehabilitation <strong>of</strong> amputees<br />

and to identify the problems they encounter with rehabilitation in the community.<br />

The non-experimental, qualitative and quantitative survey was chosen for this study for the<br />

following advantages:<br />

• It ensured that research took place in the natural clinical environment and in patients'<br />

own communities. Amputees were given the questionnaires to complete during their<br />

spare time.<br />

• It ensured a high degree <strong>of</strong> representativeness in the sample as convenience and<br />

purposive sampling method was used and patients were readily available.
