Plexuses
How do plexuses run?
Root, Trunk, Divisions, Chords, Branch
Head, neck, and shoulders
Cervical
Chest, shoulders, arms, and hands
Brachial
Back, abdomen, groin, thighs, knees, and calves
Lumbar
Pelvis, buttocks, genitals, thighs, calves, and feet
Sacral
Small region over the coccyx
Coccygeal
Roundback. Associated with a forward head
Kyphosis
Overcompensation to keep eyes level
Forward Head
Decreased lumbar curvature
Flatback Posture
Anterior shifting of the pelvis into hip extension.
Swayback Posture
Decreased lordosis and increased kyphosis
Swayback Posture
Increased curvature of the lumbar spine
Lordosis
Can be the result of obesity, osteoporosis, or spondyloisthesis
Lordosis
Lateral curvature of the spine
Scoliosis
Functional Scoliosis
Goes away without gravity. Muscular imbalances, leg-length discrepancies, nutritional deficiency
Structural Scoliosis
Always present. Bony defect of the spine
MOI for Cervical Fracture
Axial loading (a blow to the top of the head while in flexion)
S/S for Cervical Fracture
Neck point tenderness, resisted ROM, muscle spasm, cervical pain and pain in the chest and upper extremities, numbness in trunk/limbs, weakness/paralysis, loss of bladder/bowel control
Treatment for Cervical Fracture
Unconscious athlete always treated as if they have a cervical fx. Use neck collar, restricted ROM
MOI for Cervical Dislocation
Violent flexion and rotation of the head (common in divers)
S/S for Cervical Dislocation
Head typically tilts toward dislocated side. Similar to cervical fx.
Treatment for Cervical Dislocation
Realign (conservative/surgical) treat the same as cervical fracture
MOI for Cervical Sprain (Whiplash)
Sudden snap of the head
S/S for Cervical Sprain
Localized pain, point tenderness, restricted motion
Treatment for Cervical Sprain
Rule out fracture, dislocation, or disk injury, neurological evaluation, immobilization, RICE, NSAIDs, traction
MOI for Acute Torticollis (Wryneck)
Impinged or trapped synovial membrane in the cervical vertebra; holding the head in an unusual position or getting a chill from a cold draft of air.
S/S for Acute Torticollis
Point tenderness, muscle spasm, restricted motion
Treatment for Acute Torticollis
Joint mobilizations, traction, immobilization
MOI for Brachial Plexus Neuropraxia (Burner)
Stretching or compressing the brachial plexus
S/S for Brachial Plexus Neuropraxia
Radiating pain and numbness, tingling, burning sensation, loss of function in arm and hand
Treatment for Brachial Plexus Neuropraxia
Rest until symptoms have resolved, strengthening and stretching programs.
MOI for Herniated Disc
Flexion and twisting while lifting or moving an object
S/S for Herniated Disc
Sharp central pain that radiates unilaterally with dermatome down the back of the leg or across the back, lower limb weakness, worse in the morning, limited motion, point tenderness, pain with coughing, sneezing.
Treatment for Herniated Disc
RICE, E-Stim, Postural correction exercises, abdominal strengthening
Degeneration of the vertebrae, pars defect
Spondyloysis
MOI for Spondylosis
Hyperextension of the spine; typically unilaterally
S/S for Spondylosis
Mild to moderate aching pain, low back stiffness, increased pain after activity, tiredness and fatigue in low back, limited forward flexion, possible point tenderness, possible hyper mobility of injured vertebra
Treatment for Spondyloysis
Bracing, trunk stabilization, dynamic core exercises, avoid vigorous activity
Inflammatory condition of the sciatic nerve
Sciatica
MOI for Sciatica
Torsion or direct blow
S/S for Sciatica
Sudden or gradual onset, sharp shooting pain down posteriomedial thigh, tingling/numbness along nerve pathj
Treatment for Sciatica
Rest, Rule out disc protrusion, lumbar traction, NSAIDs, surgery if needed.
