MSK Flashcards
what are 3 examples of viscerogenic pain ?
Myocardial infarct - may have pain in mid- back shoulder, arm chest, LEFT arm/ body, jaw, neck
Kehr’s sign - ruptured spleen; leads to blood pooling in body cavity, and refer pain to L shoulder due to irratation of phrenic nerve (C 3,4,5.) + Kehrs sign = pressure to upper ab causes L shoulder pain
Gallstones - May refer pain to the R shoulder
What are descriptors of non MSK or viscerogenic pain?
this type of pain is described as dull, diffuse, non specific (hard to localize) due to the multiple levels of innervation. Position changes to not change pain intensity, weight, night pain, N/V, pallor, sweating, fever and off vitals.

What stages are included in stance phase for rancho los amigos? How much is spent in this phase?
initial contact (heel strike) loading response (foot flat) mid stance (midstance) terminal stance (Heel off) Pre-swing (toe off) (60%)
What stages are in the swing phase? How much is spent in this phase?
Initial swing ( acceleration)
Mid-swing (mid swing)
Terminal swing (De acceleration)
(40%)
What is initial contact? What muscles are involved ? What ROM is needed at which joints?
the beginning of stance phase when the heel touches the floor.
- Hip: 30* flexion
- Knee: extension
- Ankle: heel first ankle neutral
Gait and muscle activity
Ankle Dorsi flexors: ant-tib, flexor hallisuc longus, extensor digitorum longus, and peroneus tertius prep the heel to lower down. The quad contract to extend the knee. Hamstrings help to stabilize the knee to prevent hyperextension. The hip extensors and ABDs stabilize the trunk.
What is loading response? What muscles are involved ? What ROM is needed at which joints?
The time btwn initial contact, and the beginning of swing of the other foot. The time it takes for the entire foot to make floor contact (foot flat)
- Hip: 30* flexion
- Knee: 15* flexion
- Ankle: 15* PF
Gait and muscle activity
Ankle dorsiflexors act eccentrically to lower the foot to the ground. Quads will work eccentrically flex to accept body weight. Towards the end, PFs eccentrically work to control DF as the tibia moves over the foot. TIb posterior eccentrically controls pronation. Eventually the quads work concentrically to move the femur over the tibia. Hip extensors contract for hip extension (coming up)
What is Mid-stance ? What muscles are involved ? What ROM is needed at which joints?
When the other foot is off of the floor and until the body is directly over the leg.
- Hip: extending to neutral
- Knee: extending to neutral
- Ankle: from PF to 10* DF (the most ankle activity here going from 15* PF to 10* DF)
Gait and muscle activity:
PFs continue to act eccentrically to control DF in order to control the body moving forwards over stance limb. Min knee musc activity, but the quads contract to produce CKC knee extension . Hip ABDs stabilize the trunk and contralateral hip drop. Illiopsoas eccentrically control hip extension.
What is terminal stance? What muscles are involved ? What ROM is needed at which joints?
When the heel of the stance limb rises, and the other foot touches the ground. (heel off)
- Hip: 10* hyperexntension
- Knee: extension
- Ankle: neutral (with tibia stable and heel off by the time the other foot is in initial contact ankle reaches neutral not PF however PF is achieved in order to move ankle from 10* DF to neutral)
- Extended toes
Gait and muscle activity
PF work to propel the body forwards. Hip ABDs stabilize the hips and illipsoas continues to control rate of hip extension.
What is pre-swing? What muscles are involved ? What ROM is needed at which joints?
The time from terminal stance to before toe off. Begin when the other foot reaches IC.
- Hip: neutral
- Knee: 35* flexion
- Ankle: 20* PF
- Extended toes
Gait and muscle activity
Peak PF activity for toe off . Hamstrings kick on for knee flexion to prep for swing, illiopsoas and other hip flexors kick on for hip flexion to prep for initial swing. Body momentum also aids in this motion.
What is initial swing? What muscles are involved ? What ROM is needed at which joints?
- the first phase in the swing phase. Begin when the toe comes off and end with terminal knee flexion 60*
- Knee: 60* flexion
- Hip: 20* flexion
- Ankle: 10* PF
-Gait and muscle activity
Ankle DFs clear foot from ground and decrease the PF created in preswing. Hamstrings help with foot clearance via knee flexion. Hips flexors on to advance limb forward.
What is mid-swing? What muscles are involved ? What ROM is needed at which joints?
the time it takes for the tibia to be perpendicular with the floor
- Knee: goes form 60-30* flexion
- Hip: 20-30* flexion
Gait and muscle activity
Ankle Df contract to maintain DF knee and hip activity are minimal 2/2 forward momentum (wow)
What is terminal swing? What muscles are involved ? What ROM is needed at which joints?
when the tib is perpendicular to the floor and ends with the foot touch ing the floor.
- Knee: extension 0*
- Hip: 30* flexion
Gait and muscle activity
Ankle DF and inverters prep the foot for heel strike. Quads contract for knee extension and hamstrings work eccentrically to control rate of knee extension. Hip extensors slow hip flexion for heel to slowly return to ground.
When the Right foot is in initial contact, what will the left foot be in? What happens after initial contact with the right foot?
Preswing
the right foot will enter single leg stance
