Exercises for the spine l.jpg

Exercises for the Spine


Abdominal exercises l.jpg

Abdominal Exercises

  • Effective sit-ups emphasis lumbar flexion of the abdominal muscles

  • Hip flexor muscles (e.g. iliopsoas) can also perform lumbar flexion


Abdominal exercises3 l.jpg

Abdominal Exercises

  • Flexing the knees neutralizes the hip flexor muscles

  • Stabilizing the feet increases the strength of the hip flexors


Crunches l.jpg

Crunches

  • Flex the knees and hip to 90 degrees

  • Don’t stabilize the feet

  • Arms at side; move them closer to the head to increase difficulty

  • If hands behind head, avoid over cervical flexion

  • Slowly perform lumbar flexion

  • Exhale during lumbar flexion

  • Abdominal muscles active during first half of lumbar flexion

  • Return until head touches the floor

  • Muscles: Upper rectus Abdominis (obliques, hip flexors)


Leg pull or reverse crunch l.jpg

Leg Pull or Reverse Crunch

  • Action?

  • Lumbar flexion

  • Muscles:

  • Lower rectus abdominis, obliques, and hip flexors


Leg raises l.jpg

Leg Raises

  • Muscles: First, hip flexors then as the hips are raised off the ground, the rectus abdominis is more involved


Abdominal exercises8 l.jpg

Abdominal Exercises

  • Rectus Abdominis and Obliques dynamically contract only if actual waist flexion occurs.

  • With no waist flexion, Rectus Abdominis and External Oblique will only isometrically contract to stabilize the pelvis and waist during hip flexion.

  • It may be necessary to completely flex the hips before waist flexion is possible

  • ExRx


Abdominal exercises9 l.jpg

Abdominal Exercises

  • Muscles: Obliques (rectus abdominis and hip flexors)

  • Notice her right external oblique - rotation to the opposite side

  • Her left internal oblique - rotation to the same side


Sit ups l.jpg

Sit-Ups

  • Muscles: Rectus abdominis (obliques and hip flexors)

  • Note: Flexing or “curling” the lumbar region emphasizes the rectus abdominis


Incline sit ups l.jpg

Incline Sit-ups

  • Increased resistance


Leg raise l.jpg

Leg Raise

  • Muscles: First, hip flexors. As the upper leg passes horizontal, rectus abdominis becomes more involved


Side bends l.jpg

Side Bends

  • Action?

  • Lateral Flexion

  • Muscles:

  • Quadratus Lumborum, Rectus Abdominis, and Obliques


Slide16 l.jpg

  • Muscle?

  • Transverse abdominis


Abdominal exercises19 l.jpg

Abdominal Exercises

  • No one type of abdominal exercise is best.


Do abdominal exercises help lose weight around the waist l.jpg

Do abdominal exercises help lose weight around the waist?

No way!

FTC Charges Three Top-selling Electronic Abdominal Exercise Belts with Making False Claims (2002)

Alleges Electronic Abdominal Gadgets Won't Provide Six-Pack Abs

"Now you can get rock hard abs with no sweat"
"Lose 4 Inches in 30 Days Guaranteed"
"30% More Effective Than Normal Exercise"
"10 Minutes = 600 Sit-Ups”

These are the types of claims the Federal Trade Commission has challenged in complaints filed in federal district courts against three widely advertised electronic abdominal exercise belts - AB Energizer, AbTronic, and Fast Abs. The FTC alleges that the marketers of the devices, which use electronic muscle stimulation (EMS), have falsely advertised that users will get "six pack" or "washboard" abs without exercise.” For years, marketers of diet and exercise products have been preying on overweight, out-of-shape consumers by hawking false hope in a pill, false hope in a bottle, and, now, in a belt," said FTC Chairman Timothy J. Muris. ”Unfortunately, there are no magic pills, potions, or pulsators for losing weight and getting into shape. The only winning combination is changing your diet and exercise."


Lower back injuries l.jpg

Lower Back Injuries

  • Lumbar region is most susceptible to chronic injuries

    • Weight-loading sports that compress the spine

      • weight lifting, running

    • Rotation-causing events

      • racket sports and golf

    • Back arching events

      • rowing, swimming and volleyball


Lower back injuries23 l.jpg

Lower Back Injuries

  • Due to weak abdominal muscles and tight hamstrings.

  • Due to mechanical strain of the ligaments and joints from from inadequate warm up, weak abdominal muscles, and/or tight hamstrings.

  • Results in lordosis of the lower back.

  • Patients complain of low back pain after long periods of standing or playing.

  • Can treat with muscle strengthening exercises or anti-lordotic Boston brace.


Lower back injuries prevention l.jpg

Lower Back Injuries: Prevention

  • Strong abdominal muscles

  • Proper technique.

    • This often involves developing gluteal and quadriceps strength so that you can crouch without excessively swaying the lower back.

  • Balanced program of both stretching and strengthening.


Spondylolysis l.jpg

Spondylolysis


Spinal stenosis l.jpg

Spinal Stenosis

  • In spinal stenosis, the spinal canalnarrows and pinches the spinal cord and nerves.

  • The result is low back pain as well as pain in the legs.

  • Stenosis may pinch the nerves that control muscle power and sensation in the legs.


Herniated disk l.jpg

Herniated Disk


Herniated disk29 l.jpg

Herniated Disk

  • Causes

    • aging

    • wear-and-tear

    • excessive weight which can squeeze the softer material of the nucleus out toward the spinal canal

    • bad posture

    • improper lifting

    • sudden pressure (which may be slight)

  • Also known as a "slipped" or "ruptured" disk in the back.
