45
The muscles of the gluteal region are innervated by
the superior and inferior gluteal nerves, which come from L5-S2 roots
46
dysfunctions of the lower limb
sciatica, osteoarthritis of knees, plantar fasciitis, and gout.
47
sciatic nerve comes from
the lumbar and sacral plexus, L4-S3, and is usually a symptom of a bigger problem such as a degenerative disc disease or a bone spur in the spine
48
swelling of the piriformis muscle
sciatica
49
Osteoarthritis of the knee
affects older individuals and occurs because of natural “wear and tear”
cartilage of the knee begins to wear away, which results in friction between the bones and resulting in bone spurs
50
athletes are at risk of
Osteoarthritis of the knee
51
a sedentary lifestyle can lead to
Osteoarthritis of the knee, because of weakened muscles that can no longer properly support the knee
52
tactics to combat osteoarthritis include
increasing activity levels by doing certain exercises (within reason), lose weight if necessary, and anti-inflammatory
medications
53
Superficially on the plantar aspect of your foot is a thick layer of fascia called
plantar fascia
54
plantar fascia
helps support the arch in our feet, stemming from the calcaneus (bone in the heel) towards the metatarsals (toes).
55
cause of inflammation of plantar fascia
uncertain but specific activities that require individuals to be on their feet a lot (e.g. construction workers, teachers, military personnel, etc.) seems to be a consistent factor
56
Buchbinder
commonly target middle aged patients between 40 and 60 years old, because of prolonged standing, tiny tears form in the plantar fascia and incite an inflammatory response
57
individual continues to remain on their feet, the tears and irritation worsens resulting in sharp, stabbing pain on the plantar surface of the affected foot
Medications, prescribed orthotics, and physical therapy may be prescribed to help alleviate the pain and combat the fasciitis
58
gout
arthritis that usually affects the big toe, "disease of kings"
59
gout caused by
nutrient-rich diets, hyperuricemia (increased levels of uric acid) can develop in the blood and cause crystal formations in the joints
60
crystal formation at the joints
crystallizations are needle-shaped and therefore cause severe pain in the affected joint
61
why does gout happen?
uric acid abounds because it is produced in large quantities, the kidneys are excreting it too slowly (which could lead to kidney stones)
or
it is a combination of both (
62
Doctors usually administer NSAIDs, corticosteroids, or both
to combat gout
