Questions that should be answered:

B. Using your own results and those from other groups discuss the following:

1. Describe instruments used for each measurement and comment on the methods used to determine the joint mobility measures. How reproducible were the measurements? (See reliability coefficients.)

2. Display results.

3. Discuss the range of movements between subjects. Are there any sex differences in the range of joint movement?

4. Hip movements.
a) Rotation.
Do any of your group habitually sit on the floor with legs crossed? If so, compare his/her rotational movements with the others. Are they greater?

b) Extension.
What is affecting the range of movement?

5. Ankle.

a) Ankle.
At the extremes of the movement the ankle joint may not be the only active joint. Which other joints may contribute to the range of movement?
7. Vertebral Column.
Discuss the variations in the flexibility of the subjects. Do leisure/sporting activities affect the extent of movement?

Is flexibility of the vertebral column important to the ‘quality of your life’?

8. Draw a graph of grip strength against forearm circumference separating the males form the females. What conclusions can be drawn?

General Conclusions

Using the data collected from the volunteers and the questionnaire draw conclusions concerning the variability of the joint mobility of the class and the reasons behind them. Consider any anatomical considerations as to why there is variability between individuals.

Regarding grip strength plot a graph of grip strength against forearm circumference and right and left sides and compare males and females. What conclusions can be drawn?
