Core Strengthening
The trunk and its associated muscles make up the core. The extremities are the arms,
forearms, hands, thighs, legs, ankles/feet. Strong core muscles provide a foundation
for the extremities to attach to and work more efficiently. It is hypothesized that
a weak core can cause excessive stress on the extremity muscles, tendons, ligaments
and joints. Core strengthening is a multi-joint exercise, involving larger muscle
groups such as the chest, abdominals, back, hip/thigh, and shoulder blade muscles.
Core strengthening is often incorporated as part of a low back or neck rehabilitation
program. Because recovery or enhancement of core strength provides a stable base
for the extremities, it is also commonly part of an arm, forearm, thigh, leg or
ankle program.
Cryotherapy or Cold Therapy
Cold therapy is used to cause vasoconstriction (the blood vessels constrict or decrease
their diameter) to reduce the amount of fluid that leaks out of the capillaries
into the tissue spaces (swelling) in response to injury of tissue. Ice or cold is
used most frequently in acute injuries, but also an effective pain reliever for
even the most chronic pain. Cold therapy may be administered by using a cold pack
or an ice massage as seen in the above video.
