Abstract
It has become increasingly evident that there is a defi¬nite need for fundamental information to define the normal range of joint motion of normal Egyptians because this sub¬ject has received very little attention. The arcs of active joint motions of shoulder, elbow, wrist, hip, knee, ankle were measured in the basic planes in one hundred of normal healthy subjects at different age groups. Also passive motions of wrist, elbow, knee, ankle and 5th metacarpophalangeal joint will be recorded to deter¬mine degree of hypermobility in normal subjects. We analysed the influence of age, sex and occupation on these motions both active and passive. Methods of assessing joint motion: 1.Double armed goniometer. 2.Leighton f l exome te r , 3.Electrogoniometer or Elgon 4.Photograph films. 5.Flexible plastic or metal tape. In our study we used the double armed goniometer the most common method with one arm stationary and the other movable, the axis was placed at the center of joint. For technique of measuring the subject was supine for all measurements except extension of shoulder and hip (prone). Factors affecting joint motion: The range of motion of joints give wide variations in different subjects which are healthy and normal these varia¬tions are contributed to the following factors: 1.Constitution of joint 2.Age 3.Sex 4.Race 5.Body build 6.Hypermobility 7.Occupation. The data of our study were computeri~ed by ABC/24-64K and IBM?XT 640K and Megamicro computer non parametric statistics were used because cases were not normally distributed. Formulae used for statistical analysis: 1.Median 2.Quartile and percentiles 3.Kruskal-Wallis one way Anova test 4.Chi square (X2) and pearson’s (R) tests 5.Mann-Whitney U-test 6.Cross tabulation.
