Chapter 10: Flexibility and Neuromotor Fitness Assessments

1. Overview of Flexibility

  • Definition: Flexibility is essential for daily activities and physical engagement.

  • Low-Back Pain (LBP): Impaired flexibility can lead to or exacerbate LBP; approximately 25% of adults experience LBP within three months.

  • Range of Motion (ROM): Capacity to move joints freely through their normal ROM.

2. Factors Influencing Flexibility

2.1 Joint-Specific Factors

  • Joints Involved: Different joints have different mobility.

  • Joint Shape/Position: Proper alignment is crucial.

  • Soft Tissue Structures: Includes muscles, tendons, ligaments, and joint capsules.

  • Muscle Spindle Reflex: Activation affects flexibility; functional ROM ensures efficient body movement.

2.2 Relative Flexibility

  • Definition: Stiffness in one area may cause compensatory movement in another.

  • Importance: Recognizing and addressing these compensations can alleviate pain and dysfunction.

3. Factors Affecting ROM

3.1 Age and Sex

  • Decline with Aging: ROM decreases by 0.6% per year for females and 0.8% for males.

  • Joint-Specific Losses: Greater flexibility loss in shoulder/trunk compared to elbows/knees. Lumbar flexion shows more loss than rotation.

3.2 Posture

  • Impact of Poor Posture: Incomplete ROM can shorten the soft tissues, making corrections harder.

3.3 Previous Injury

  • Influence of Injuries: Injuries can decrease flexibility in affected areas and potentially increase hypermobility in others.

  • Assessment: Complete injury history vital for flexibility evaluation.

3.4 Diseases Affecting Flexibility

  • Arthritis Impact: Leads to degeneration of cartilage, affecting movement.

    • Rheumatoid Arthritis (RA): Common in females, results in joint stiffness and decreased ROM.

    • Osteoarthritis (OA): Affects 90-95% of arthritic cases, more prevalent after age 40, resulting from mechanical and cellular factors.

4. Osteoporosis and Flexibility

  • Definition: Loss in bone mass or density usually linked to aging, being female, and inactivity.

  • Common Sites: Indicates risk factors prevalent at the hip, wrist, and vertebrae.

  • Exercise Benefits: Weight-bearing activity boosts cancellous bone density.

5. Flexibility Testing

  • Types of Assessments: Flexibility can be evaluated quantitatively (degrees with goniometer) or qualitatively (mobility classifications).

6. Assessing Specific Joint ROM

6.1 Iliofemoral ROM (Hip Joint)

  • Association with Low-Back Pain: Tightness in hip muscles can limit pelvis movement.

  • Muscle Tightness:

    • Hip flexors (e.g., psoas) cause anterior pelvic tilt.

    • Hip extensors (e.g., hamstrings) lead to posterior pelvic tilt.

6.2 Tests for Hip ROM

  • Thomas Test: Assesses hip flexor tightness.

  • Active Knee Extension (AKE) Test: Evaluates hamstring tightness.

  • Ober and Piriformis Tests: Assess iliotibial band and piriformis tightness, respectively.

6.3 Other ROM Tests

  • Ely’s Test: Measures quadriceps flexibility.

  • Fingertips-to-Floor Test and Sit-and-Reach Tests: Assess hip flexibility but may increase spine injury risks if hamstrings are tight.

7. Spinal ROM and Function

  • Definition: Functional spinal unit involves adjacent vertebrae and intervertebral discs.

  • ROM Impact: Reduced spinal mobility is linked to increased low-back pain.

7.1 Measuring Spinal ROM

  • Assessment Methods: Goniometric measures and flexibility tests like the active trunk extension test (trunk lift).

8. Neuromotor Fitness

  • Components: Balance, coordination, agility, gait, reaction time, and proprioception.

  • Importance: Facilitates performance in ADLs and maintains health.

9. Neuromotor Fitness Assessments

  • Types of Tests:

    • 4-Stage Balance Test and Unipedal Stance Test: Evaluate balance stability.

    • Standing Reach Test: Measures flexibility and stability.

    • 8-Foot Up and Go Test: Assesses functional mobility in older adults.


Key Concepts on Factors Affecting Range of Motion (ROM) and Low Back Function

  1. Factors Affecting ROM:

    • Age and Sex: ROM decreases yearly (0.6% for females and 0.8% for males); shoulder/trunk lose flexibility more than elbows/knees.

    • Posture: Poor posture can lead to shortened soft tissues affecting ROM.

    • Previous Injury: Injuries may decrease flexibility in the affected area or increase hypermobility in others.

    • Diseases: Conditions like arthritis lead to joint stiffness and decreased ROM.

      • Rheumatoid Arthritis (RA): Common in females, resulting in joint stiffness.

      • Osteoarthritis (OA): Affects 90-95% of arthritis cases, prevalent after age 40.

  2. Impacts on Low Back Function:

    • Impaired flexibility can increase the risk of low-back pain (LBP).

    • Approximately 25% of adults experience LBP within three months, linked to joint and muscle tightness.

Flexibility Tests (pp. 222-226)

  1. Thomas Test: Measures tightness in hip flexors.

  2. Active Knee Extension (AKE) Test: Evaluates hamstring tightness.

  3. Ober Test: Assesses iliotibial band tightness.

  4. Piriformis Test: Measures tightness in the piriformis muscle.

  5. Ely’s Test: Measures quadriceps flexibility.

  6. Fingertips-to-Floor Test: Assesses overall flexibility, particularly the hamstrings and spine.

  7. Sit-and-Reach Test: Evaluates hip flexibility but may risk spine injury if hamstrings are tight.
