1 TSI Summit 2008: Session #606 The Mechanics of Low Back Pain and Corrective Solutions Eric Beard Senior Master Instructor National Academy of Sports Medicine

2 Description Eighty percent of adults suffer from back pain. This means that everyone has at least one client whose back pain limits their ability to exercise or perform in athletics successfully. Given this statistic, will you have the right strategy to keep your client moving pain-free? This presentation will cover the functional anatomy of the lumbopelvic-hip complex as well as teach you how to become proficient in performing assessments for the low back. You will learn how to utilize the exercises, programs and tools to implement corrective strategies for low back impairments, as well as how to market your abilities in a clinic or health and fitness facility. Topic: Personal Training Level: Intermediate Type: Lecture

3 Objectives Explore possible etiologies of back pain Conduct an anatomical review Introduce movement assessments Identify common movement system impairments that lead to and/or accompany back pain Present a systematic process to restore muscular balance and optimal movement system function

4 What Can Cause Back Pain? Congenital conditions Scoliosis Kyphosis Physical trauma Car accidents Falls Sports injuries Stress Degenerative conditions Arthritis Disc disease Cancer Abdominal aneurysm IBS Infection Meningitis Fibromyalgia Hormonal conditions Repetitive movements And more Also poor posture due to

6 Results = Imbalances

7 Effects of Poor Posture Sets the body up for Postural Distortion Patterns. Predictable patterns of muscle imbalance Short/Tight Muscle Lengthened/ Weak Muscle Feels tight, is lengthened Feels tight, is shortened MUSCLE IMBALANCE

8 American Pain Foundation million respectively Pain affects more Americans than Diabetes, Coronary Heart Disease and Stroke, and Cancer combined The annual cost of chronic pain in the US is estimated to be $100 billion ($100,000,000,000)

9 American Pain Foundation 1) Low back pain 27% 2) Severe Headache/ Migraine 15% 3) Neck Pain 15% 4) Facial/TMJ pain 4%

10 More Good News Of the 8/10 people in the U.S. who will experience back pain 50% of those people will experience recurring bouts of low back pain To say it another way 4/10 people in the US will have recurring back pain 1 in 4 suffered a day long bout of back pain in the last month 1 in 10 say the pain lasted at least for one full year

11 US Overworked According to studies Americans work the longest hours among industrialized countries ½ of the white collar workers log more than 50 hours per week More than 405 million business trips are taken each year in the U.S. 42% of Americans are working more hours now than five years ago

12 Low Back Statistics 2 nd most common reason for a doctor s visit 3 rd most common reason for surgery 5 th most common reason for hospitalization Highest rate of occurrence 45 to 64 years of age

13 Low Back Statistics Only 5% of those with back pain have a demonstrated specific cause Less than 1-2% actually have a pinched nerve (*this actually a fabricated diagnosis, it does not really happen) A bulging or herniated disc is common over the age of 45 but is typcially asyomtomatic

14 Acute vs. Chronic Back Pain ACUTE Initial onset of pain Spontaneous resolution in 2-4 weeks for 90% of patients. People can have Acute on Chronic exacerbations of pain that act like first onset CHRONIC Back pain that does not resolve within 3 months Pain that partially improves, but never completely goes away The baseline pain from which people experience exacerbations

15 How Do People Deal With Pain? What does that cost the nation in productivity?

16 What do we know? Chronic pain is at an all time high In a cross-sectional study of 100 patients (Cibulka) demonstrated unilateral hip rotation ROM asymmetry in patients with SI joint regional pain Hodges and Richardson 1998 reported that slow speed of contraction of the transverse abdominus during arm and leg movements was well correlated with LBP O Sullivan et al 1997 found that synergist substitution of the rectus abdominus for the agonist transverse abdominus during the abdominal drawing-in maneuver suggesting less efficient intersegmental stabilizing mechanisms and greater shear forces at the inter-vertebral joints Hides et al 1994 demonstrated unilateral atrophy of the multifidus in patients with low back pain

28 Movement Assessments

29 The Kinetic Chain The Human Movement System is made up of the nervous, muscular and skeletal system. Nervous System Muscular System Skeletal System Posture is the alignment and function of the human movement system.

30 Importance of Posture Proper posture: Length-tension relationships Force couples and joint motion Neuromuscular Efficiency Ability of the nervous system to properly recruit all muscles in all planes of motion.

31 Movement Assessments Overhead Squat A two-legged squat performed with: the arms held overhead From a bilateral standing posture assesses: total body structural alignment, dynamic flexibility, and neuromuscular control Squatting requires: optimal motion in the ankles, knees, and hips. Having the arms elevated overhead: stresses the musculature surrounding the shoulder complex increases the demand placed upon the core stabilizing muscles

32 LPHC: Low Back Arches Ideal Compensation Low Back Arches: Take notice of the area from approximately the mid back through the Sacral Complex. If the area is arched then this area will appear with an excessive lumbar or convex curve.

33 LPHC: Low Back Arches Overactive Muscles Hip Flexor Complex Erector Spinae Latissimus Dorsi

34 Iliopsoas (Psoas major + Iliacus) Origin: transverse processes and bodies of L1-L4, ilium Insertion: lesser trochanter of femur Concentric Actions: hip flexion, external rotation, spinal extension (Bilateral), lateral flexion and flexion (Unilateral)

35 Hip Flexors (Rectus Femoris) Origin: anterior inferior iliac spine (ASIS) Insertion: tibial tuberosity by way of the patellar tendon Concentric Actions: knee extension, hip flexion

36 Tensor Fascia Latae / Iliotibial Band Origin: illiac crest, posterior to the ASIS Insertion: lateral aspect of tibia via the ITB Concentric Actions: open chain-hip flexion, abduction, internal rotation closed chain changes to hip adduction and external rotation of tibia

37 Erector Spinae (Iliocostalis) Attachments: ilium, sacrum (TLF) spinous and transverse processes of lumbar, thoracic, and cervical vertebrae; ribs 1-12 and mastoid process Concentric Actions: extension, rotation and lateral flexion of the spine

38 Latissimus Dorsi Origin: Sacrum via the thoracolumbar-fascia, iliac crest; lumbar vertebrae, spine of T6- T12, lower three or four ribs, inferior angle of scapula Insertion: medial lip of the inter-tubercle groove of the humerus Concentric Actions: adduction, extension and internal rotation of the humerus

39 LPHC: Low Back Arches Underactive Muscles Abdominal Complex Gluteus Maximus Hamstrings

40 Transverse Abdominus Origin: thoracolumbar fascia, cartilage of the last six ribs and iliac crest Insertion: linea alba, pubic crest Concentric actions: increases intraabdominal pressure and supports abdominal viscera

41 Abdominal Complex (Rectus Abdominus) Attachments points: various aspects of the pelvis and the ribcage Concentric Actions: flexion, rotation, lateral flexion of the spine and posterior rotation of the pelvis

42 Gluteus Maximus Origin: iliac crest, sacrum, coccyx, and the sacrotuberous and sacroiliac ligaments Insertion: ITB and gluteal tuberosity of the femur Concentric Actions: hip extension, abduction, and external rotation

43 Hamstring Complex Origin: ischial tuberosity and linea aspera of femur Insertion: tibia and fibula Concentric Actions: knee flexion, hip extension, posterior rotation of pelvis, rotation of the tibia

45 Corrective Exercise Strategy Integrate Activate Lengthen Inhibit

46 Plan of Action Corrective Exercise Continuum Inhibit Lengthen Activate Integrate Inhibitory Techniques Lengthening Techniques Activation Techniques Integration Techniques Self Myofascial Release Static Stretching Neuromuscular Stretching Positional Isometrics Isolated Strengthening Integrated Dynamic Movement

47 Inhibit: Self Myofascial Release Pressure (tension) stimulates GTO Inhibits Muscle Spindle Allows for optimal tissue lengthening Slow steady roll and static 30-sec. hold can work

48 Inhibit: Self Myofascial Release Contraindications for Self Myofascial Release Malignancy Osteoporosis Osteomyelitis (infection of bone tissue) Phlebitis (infection of superficial veins) Cellulitis (infection of soft tissue) Acute rheumatoid arthritis Blood clot Goiter (enlarged thyroid) Eczema and other skin lesions Open wounds Healing fractures Obstructive edema Advanced diabetes Hematoma or systemic/ localized infection

49 Inhibit

50 Lengthen: Static Stretching Static stretching may produce both mechanical and neural adaptations that result in increased ROM Isometric hold for 30-60sec

51 Lengthen

52 Activate: Isolated Strengthening Develops: Intra-muscular coordination Local muscular endurance Local metabolic efficiency Not intended for hypertrophy of muscles

53 Activate

54 Integrate: Dynamic Movement Enhances: functional capacity of the human movement system by increasing multiplanar neuromuscular control Improves intermuscular coordination

55 Integrate

56 Intervertebral vs. Lumbo-pelvic Intervertebral Stabilizers Local musculature Transverse Abdominus Multifidus Pelvic Floor Diaphragm Lumbopelvic Stabilizers Global musculature External Oblique Internal Oblique Quadratus Lumborum Stabilizers

57 Techniques to Facilitate Deep Core-Intervertebral Stabilizers Abdominal Drawing-In Facilitates contraction of the Local Stabilizers Also, facilitates contraction of the diaphragm and pelvic floor musculature Exercise to promote intervertebral stability Under utilized stability training Must come first!

58 Techniques to Facilitate Dynamic Lumbo-Pelvic Stabilizers Abdominal Bracing Facilitates contraction of the Global Stabilizers Exercise to promote lumbopelvic stability Over-utilized strength training Important, but should be done second to drawing-in maneuver

59 Spine Stability = Intervertebral Stability + Lumbopelvic Stability Hodges Model Focuses on intervertebral stability McGill Model Focuses on lumbopelvic stability

60 Core Stabilization Exercises Keep pelvis and spine neutral, abdominals gently engaged, hold static or lift and lower slowly reps, rest, repeat

61 Core Stabilization Exercises Keep pelvis and spine neutral, abdominals gently engaged, hold static or lift and lower slowly reps, rest, repeat

62 Core Strength Exercises 8-12 reps with control, flex, extend and rotate the spine and hips as needed

63 Core Strength/Power Exercises 8-12 reps as fast as you can safely control

64 Comprehensive Treatment and Prevention See a licensed medical professional if you have active pain, chronic pain, referred symptoms etc. Chiropractic Physical Therapy Acupuncture Therapeutic Massage Therapeutic Modalities Ice, heat, cold laser, TENs, ultrasound and more Regular (specific) physical activity!!!
