- Flexibility refers to the range of motion at a joint or series of joints and is specific to each joint .
- Factors that influence flexibility of a joint are the bony structure, the amount of tissue at the joint, and the elasticity of the muscles, tendons, and ligaments at the joint.
- Flexibility is influenced by age, gender, and physical activity.
- The maintenance of flexibility of the hamstrings and low back muscles is important in the prevention of low back pain .
- Normal body weight and good posture are also necessary for a healthy back.
- Ballistic stretching is counterproductive to improving joint elasticity and may contribute to injury.
- Static stretching is the recommended type of exercise. Stretches should be held for 15 to 30 seconds and repeated at least twice.
- Stretching should not be painful.
- Stretching exercises can be performed daily.

- Proprioceptive neuromuscular facilitation is the most effective but most difficult form of stretching.
- Proprioceptive neuromuscular facilitation combines passive movement with isometric contractions .
- The most accurate measurement of flexibility is obtained with a goniometer.
- Low back pain is the most common reason for visiting a physician.
- Factors associated with low back pain include excess weight, poor posture, inactivity, fatigue, weak abdominal muscles, high heels, and stress.
- Discuss what guidelines should be followed for safe and effective stretching.
