Musculoskeletal Disorders


Published on

Musculoskeletal Disorders or MSDs are injuries and disorders that affect the human body’s movement or musculoskeletal system (i.e. muscles, tendons, ligaments, nerves, discs, blood vessels, etc.)

Musculoskeletal Disorders

  1. 1. Erik Nason, MS, ATC, CSCS, MBA KSC RehabWorks
  2. 2. KSC RehabWorks was established in 1997 to provide free on-site physical medicine and rehabilitation for work, non-work, sports- related injuries and post- surgical cases.
  3. 3. Musculoskeletal Disorders or MSDs are injuries and disorders that affect the human body’s movement or musculoskeletal system (i.e. muscles, tendons, ligaments, nerves, discs , blood vessels, etc.)
  4. 4. The human and financial costs of musculoskeletal disorders impose a significant burden on workers and businesses in the United States. Properly defining MSD and knowing the different types, costs and risks associated with MSD is an educational building block you can use to create an effective injury prevention program.
  5. 5. The employer is responsible for providing a safe place of work, sound ergonomic principles, proper training for all employees, and a clear focus on safety culture within all levels of the organization. Each employee is responsible for taking care of their bodies and staying fit for the work they have chosen to do.
  6. 6.  Good health of the musculoskeletal system is maintained when there is a balance between fatigue from physical activity and the system’s recovery process.
  7. 7.  MSDs result when exposure to physical activity causes gradual wear and tear, micro trauma, and soft tissue fatigue to outpace the system’s recovery, leading to inflammation, pain and dysfunction.
  8. 8.  How many here know what Myofascial Pain is?  How many know what a trigger point is?  How many have experienced a tightness in your muscles causing you to lose ROM and cause pain?
  9. 9. Currently reported to affect approximately 85% of the population at some point during their lives The mean prevalence of this condition among middle-aged adults (30–60 years) is reported to be 37% in men and 65% in women, respectively  In the elderly (>65 years), the prevalence reaches 85%
  10. 10. Combination of two Latin words “Myo” meaning muscle “Fascia”- meaning connective tissue surrounding the muscle
  11. 11. Tough connective tissue that lies just under the skin It surrounds every organ, muscle, bone, ner ve and blood vessel Extends uninterrupted from head to toe
  12. 12. Hypersensitive areas Palpated as a nodule within a tight band of muscle Can cause pain, tingling, burning, weakness and loss of range of motion (ROM)
  13. 13.  MFP is an umbrella term that is given to TrPs and referred pain  TrPs are the TRUE source of soft tissue pain  MPS is more of a medical “garbage” term expressing the fact that the person is experiencing broad soft tissue pain unrelated to any MOI- possibly the result of multiple TrPs with referred pain  Tight MF and/or tight, fatigue, strained muscles can develop active TrPs therefore creating pain
  14. 14. Chronic or acute pain disorder Initiated trough TrP’s, inducing referred pain into a specific body region depending on the muscle involved Typically occurs after a muscle has been contracted repetitively Untreated it can cause tightness, tenderness, stiffness, popping and clicking, loss of ROM
  15. 15. 2 Types • Latent • Active
  16. 16. • Only painful upon stimulation, stiffness, decrease in ROM
  17. 17. • When a latent trigger point becomes hyperactive, resulting in a localized spasm, creating a palpable knot, and producing referred pain.
  18. 18. “Pain that arises in a trigger point, but is felt at a distance, often entirely remote from the source”
  19. 19. Prevalent in the head, neck, shoulders, hips and low back
  20. 20. Tight muscle Tender points in muscle Palpable nodules Decreased range of motion Weakness without atrophy As "dull," "achy," or "deep” pain that radiates and is non specific Arises without a determined MOI Local spasm in affected muscle
  21. 21. Sciatica Migraine headaches Fibromyalgia Shoulder Impingement Plantar fasciitis ITB syndrome Thoracic Outlet Syndrome
  22. 22. Stress Posture Ergonomics
  23. 23. History • How long has this been going on? • Has anything in your daily routine changed that might evoke this? • What makes it better or worse? • Has there been any trauma to this area currently? • Any limitations of ROM since onset? • Do you notice a decrease in pain over the weekend? • What type of work do you do?
  24. 24. What is your posture like? How are your workstation ergonomics? Do you exercise on a daily bases?
  25. 25. Technique used to help lengthen the muscle and fascial layers and enable them to remain in the lengthened state Goal is to decrease the amount of tension to the trigger points and decrease their hypersensitivity
  26. 26. SELF TREATMENTS  Stretching  Massage  Heat or Ice  Foam Roller  Trigger Ball  Strengthening MEDICAL TREATMENTS  Trigger Point Injections  Acupuncture REHABILITATION  Ultrasound  Stretch and Spray  Therapeutic massage  Electrical Stimulation
  27. 27. Your prevention strategy must include these 5 pillars to be effective: • 1. Utilize ergonomic/industrial hygiene program • 2. Employee education & training • 3. A proactive early intervention strategy • 4. Regular evaluation & continuous improvement • 5. Establishing a culture of Safety & Wellness for all employees.
  28. 28. Microbreaks • Every 30-60 minutes • Lasts only 2-5 minutes • Goal is to break up the static posture and reverse all motions Exercise • Overall physical health is key
  29. 29. 1. Myofascial pain and TrPs are caused from a contraction of the muscle fibers, such as repetative motions or injury 2. Self techniques that help enhance the treatment of MPS and TrPs include stretching, strengthening, foam rolling and massage 3. Techniques involved in the prevention include microbreaks, postural training, exercise and stress
