Question
9. The following data were collected by measuring the range of motion (ROM) at various joints with a goniometer: Measured ROM (mark with "x for visual estimation) Right 87 119 48° 85° 55° 30° 145° Left 86° 120 49 86 Average ROM 95° Movement Abduction Adduction Flexion Extension Abduction Adduction Flexion Joint Shoulder 127 Elbow 55° 89 Hip 45° 26° 32 45 Knee 140 What conclusions can you make about this individual's flexibility? 10. Identify sources of experimental error when measuring the range of motion with a goniometer.
Explanation / Answer
Range of motion is a measurement of movement around a joint. It is measured by using goniometer.
Ans.9) According to given data, the upper extremity ROM is limited at shoulder and elbow joints as the normal range of motion at shoulder during abduction is 0 to 180 degrees and at elbow during flexion is 0 to 135 degrees. Thus the individual's flexibility is altered at shoulder and elbow joints which could be due to injury or various other reasons.
The lower limb flexibility of the individual is almost in normal range.
Ans10.) Sources of error when measuring ROM with the goniometer can be-
1. Failure to identify the bony landmarks.
2. Variation in hand push by the therapist.
3. Difficulty in moving body part you're trying to move.
4. During taking the reading of goniometer.
