  2. 2. Bone Health<br /> Increased physical activity,<br /> - especially weight bearing and <br /> - resistive exercises<br /> stimulates bone building<br />via the piezoelectric effect<br /> of contracted muscle on bone<br />

  9. 9. Preventive exercise<br />Recommended<br />Alife long dedication to:<br /> physical activity<br /> exercise<br />
  10. 10. Preventive exercise<br />Proposed: <br />Children aged 8 and older… 60 min. daily<br />Adults … 30 min. daily<br />
  11. 11. Therapeutic exercise<br />Essential element<br /> of the rehabilitation program <br />for the patients with osteoporosis<br />Tailored to the patient’s level of fitness<br /> and anticipated propensity to fracture<br />
  12. 12. Therapeutic exercise <br />the term Therapeutic: relates to the treatment of disease, or physical disorder<br />the term Exercise: refers to bodily exertion for the sake of training, or improvement of health, (including those to develop Endurance, Strength, Flexibility, and Proprioception)<br />
  13. 13. Therapeutic exercise<br /> Hippocrates (460 to 370 B.C.)<br />reportedly advocated exercise as an important factor in the healing of injured ligaments<br />Hindus and Chinese (1000 B.C.)<br />used Therapeutic Exercise in the treatment of athletic injuries<br />
  14. 14. Therapeutic exercise Principles<br />Principle of Specificity<br />Principe of Reversibility<br />Principle of Progression<br />Principle of Initial Value<br />Principle of Diminishing Returns<br />
  15. 15. Therapeutic exercise1.Principle of Specificity<br />Exercise should stress the specific physiologic system being training<br />to patients with Normal Bone Mass: should stress sites most at risk of fracture (i.e., hip, spine, wrist<br />Osteopenia and Osteoporosis: exercise for Osteogenesis<br />High-impact exercises (jumping and strength training), better than low-to-moderate (brisk walking), and has positive bone mass effect at spine and hip, in as little as 5 to 10min./day<br />
  16. 16. Therapeutic exercise 1. Principle of Specificity<br />High-Impact exercise: Notfor very low bone mass and multiple fractures. They need skeletal protection while building strength, and increase balance and flexibility<br />Isometric, core-strengthening ex. With the spine in neutral position: for all patients.<br />Spinal flexion: not for low bone mass<br />
  17. 17. Therapeutic exercise2. Principle of Reversibility<br />The Positive effect of ex., will slowly be lost if the program stops<br />A Lifelong dedication to exercise and Physical Activity to prevent bone changes with aging, and abandonment of exercise goals<br />Sarcopenia(muscle mass loss 5% per decade, after age 30, and more after 65), may be reversed by exercise.<br />Emphasize bone strengthening, while it still has adaptive ability, especially in the elderly and persons with disability<br />
  18. 18. Therapeutic exercise2.Principle of Reversibility<br />Passive Standing: is not recommended for active adults exercise<br />Passive Standing: is a rehabilitative strategy to prevent bone loss to severe disability such a spinal cord injury through the use of a standing frame or standing wheelchair.<br />
  19. 19. Therapeutic exercise3. Principle of Progression<br />To Increase Bone Mass, the stimulus must exceed previous bone-loading activity.<br />Progressive Resistive Increase in the Intensity exercises, are site specific (i.e. hip) for the bone health and improved functional capacity.<br />Slowly increasing time or intensity 10% weekly to avoid mechanical bone stress<br />
  20. 20. Therapeutic exercise4.Priciple of Initial values<br />Patients who initially have low capacity will have the greatest functional improvement from a given program<br />Attention for Inactive Participants, to begin with short sessions, of low intensity and progress <br />
  21. 21. Therapeutic exercise5. Principal of Diminishing Returns<br />There is a biologic ceiling to exercise-induced improvements in function. As this ceiling is approached, greater effort is needed to achieve minimal gain.<br />Optimal Calcium Intake for all; (if no contraindications), with Physical Activity, improve bone mass. Calcium supplements in postmenopausal women reduce bone loss by 2%, and 23% spine fractures.<br />
  22. 22. Therapeutic exercise5. Principle of Diminishing Return<br />Vitamin D supplements may reduce spine fracture by as much as 7%.<br />Adequate Caloric Intake andGlycemic Index must support exercise<br />Weight loss, with Adipose tissue loss, and depletes estrogen production stores, may cause amenorrhea in females increasing the risk of osteoporosis and stress fractures <br />
  23. 23. Therapeutic exercise5.Principle of Diminishing Return<br />The prevention of falls and fractures, through an ongoing exercise program, with proper nutrition, strength, and aerobic capacity, should be coupled with adjunctive measures such as the provision of adequate support for the spine, pain management, and psychological support when developing objectives for long term goals.<br />

  28. 28. SPEED Program<br />in Osteoporotic-KyphoticWomen, through a Spinal Proprioceptive Extension Exercise Dynamic (SPEED) Program, intervention with a spinal weighted kypho-orthosis (WKO)<br />Significant Reduction in Risk of Falls and Back Pain<br />Balance, gait, and risk of falls improved significantly with the 4-week SPEED program (using CDP = computerized dynamic posturography)<br />
  29. 29. SPEED Program REDUCING RISK OF FALLS IN OSTEOPOROTIC-KYPHOTIC WOMEN<br />FIGURE 1. An 86-year-old woman with osteoporosis and kyphosis.

  34. 34. T score Reduction to −1 to −2.5 SD (Osteopenia)<br />
  35. 35. T Reduction to -2.5 SD or more (Osteoporosis)<br />Pharmacologic intervention<br />Pain management<br />Range of motion, strengthening, coordination<br />Midday rest, heat or cold, stroking massage, if needed<br />Back extensor strengthening<br />Walking 40 min/day as tolerated; Frenkel exercises<br />Aquatic exercises once or twice a week <br />Fall prevention programme<br />
  36. 36. T Reduction to -2.5 SD or more (Osteoporosis)<br />Postural exercises : WKO program with pelvis tilt and back extension<br />Prevention of vertebral compression fractures (orthoses as needed)<br />Prevention of spinal strain (lifting ≤ 5- 10 lb)<br />Evaluation of balance, gait aid<br />Safety and facilitation of self-care through modification of bathrooms and kitchen, occupational therapy consultation<br />
  37. 37. T Reduction to -2.5 SD or more (Osteoporosis)<br />Start strengthening program with 1-2 lb and increase, as tolerated, to 5 lb in each hand<br />Speed program, if needed<br />Hip protective measures<br />
  38. 38. New Hypothesis on the Most Effective Exercise to Reduce the Risk for Vertebral Fracture<br />Back strengthening exercises, performed in a prone position rather than in vertical position, (nonloading), can decrease risk of vertebral fractures through improvement of horizontal trabecular connections. The exercise needs to be progressive, resistive, and nonloading to avoid vertebral compression fracture.<br />

The most extensive involvement is at T3, T8 through T11, T12, and L4.  <br />
  42. 42. Spinal Cord Injury and Exercise <br />Intensive exercise preserve bone mass of upper limbs,<br /> butdid not stop demineralization of lower body<br />Danger to damage joints or bone fractures when pushing wheel chair or do transfers<br />Recommended exercises: weight bearing using a standing frame or harness, treadmill training, Parastep, and functional electrical stimulation<br />The PASIPD questionnaire: (Physical Activity Scale for individuals with Physical Disabilities) can be useful in assessing levels of activity.<br />Need more controlled studies using physiological loads to examine the effects of the above methods<br />

  51. 51. Conclusion<br />Patient’s education, can contribute to prevention, better understanding and management, of the consequences of osteoporosis.<br />Posture and exercise programs, body mechanics,increasing strength and aerobic capacity, fall reduction strategies, is an essential component of both short-term and long-term interventions, for both men and women, which lead to <br />a better quality of Aging.<br />
