22
Q

Health concerns very common in wheelchair users?

A
  1. Lower limb atrophy
  2. Osteoporosis
  3. Weight management
23
Q

Health concerns very common in wheelchair users because of a decrease in: (3)

A
  • Muscle contraction (paralysis)
  • Mechanical loading on bones
  • Energy expenditure
24
Q

Health concerns in SCI - 6. ANS dysfunction during exercise

A
  • Decrease heart beat
  • Decrease BP
  • Sweating impairment
  • Impairment of the vasoconstrictor function = decrease blood to heart = less oxygen to muscles = early fatigue
25
What can you do to make sure the BP does not increase when exercising?
Train in horizontal position
26
Cardiac sympathetic nerve fibers originate from __ to __
T1 to T4 (partly from T5)
27
ANS dysfunction can be present in ___ and high ____ (lesions at T5 and above)
Quadriplegics, paraplegics
28
Where does the ANS signal originate from?
Brain stem
29
Recommendations for exercise programming
High intensity exercises may not be tolerated in person with quadriplegia and high paraplegia because of hypotension (impaired blood distribution)
30
Cause of hypotension
S.ANS (ANS dysfunction)
31
Symptoms of hypotension
Dizziness or nausea (feeling faint)
32
Recommendations for exercise programming - special recommendations
Decrease cardiovascular capacity and endurance after SCI (50% in paraplegia, 75% in quadriplegia)
33
Cardiovascular training may include
Arm ergometer and locomotor training with crutches or body weight support (overhead harness)
34
Benefits of arm ergometer (3)
Suitable to use either in the home or in the center Workload can be adjusted easily Grip cuffs used for quadriplegics
35
Benefits of locomotor training with crutches (2)
Can increase muscle strength and bone mineral density | Can prevent pressure sores (increase blood circulation)
36
Rollers are to wheelchair users what ____ are to ambulatory runners
treadmills
37
To prevent upper-extremity overuse syndromes (in wheelchair users) - (3)
- Vary exercises from week to week - Strengthen muscles of the upper back and posterior shoulder - Stretch muscles of anterior shoulder and chest
38
To prevent contractures and injury
Stretching exercises for lower + upper extremities
39
Example of seated flexibility exercises (4)
???
40
