,Sleep quality is ________ related to subsequent pain intensity in patients with acute
LBP.
________ ________ needed to determine whether targeting sleep improvement
contributes to ________ reduction. - ✔✔Sleep quality is strongly related to subsequent
pain intensity in patients with acute LBP.
Future research needed to determine whether targeting sleep improvement contributes
to pain reduction.
The bidirectional relationship between pain intensity and sleep disturbance/quality in
patients with low back pain. Alsaadi et al. 2014:
______ LBP patients, ______ wore armbands to measure sleep for ______ days - ✔✔80
LBP patients, 50 wore armbands to measure sleep for 7d
The bidirectional relationship between pain intensity and sleep disturbance/quality in
patients with low back pain. Alsaadi et al. 2014 - RESULTS:
Night of ______ ______ ______, difficulty falling sleep, waking up, and low sleep
efficiency were followed by a day with ______ ______ intensity.
Day with ______ ______ intensity associated with ______ in the subsequent night's sleep
quality, increase sleep latency, waking up, and low sleep efficiency - ✔✔Night of poor

, sleep quality, difficulty falling sleep, waking up, and low sleep efficiency were followed
by a day with higher pain intensity.
Day with higher pain intensity associated with decrease in the subsequent night's sleep
quality, increase sleep latency, waking up, and low sleep efficiency
T or F:
There is a cyclic pattern between pain and poor sleep - ✔✔TRUE
Recall - Bed Rest and Back PainMcGill - Low Back Disorders:
-Bed rest reduces ______ load below the disc osmotic pressure
-This results in an ______ of fluid to the disc
-This occurs over an ______ hour sleep period
-However it also continues up to ______ hours
-This is suspected to cause ______ - ✔✔-Bed rest reduces hydrostatic load below the
disc osmotic pressure
-This results in an inflow of fluid to the disc
-This occurs over an 8 hour sleep period
-However it also continues up to 40 hours
-This is suspected to cause backache
When is your pain the worst? - ✔✔If it's worse in the morning, that may indicate an
issue with sleep (quality, ergonomics)
List the 4 Questions of Wang's sleeping questions & diagram - ✔✔1.Do you sleep with a
partner?
