- ✔✔mobility and stability: essentials-(open chain activity) DISTAL to PROXIMAL timing is considered to be normal -->
(consider what moves first when reaching for a cup of coffee)
-what happens to the sequencing when distal component is fixed? --> it is the opposite
--> therefore, during a closed chain activity, proximal segment then moves over fixed
distal (consider sit to stand)
**proximal control develops before distal control - ✔✔8. Normal Timing
-advanced technique
-manual firing of muscle spindles to initiate or facilitate muscle contraction & to
decrease muscle fatigue
-must be followed by resistance for facilitation to occur (otherwise, inhibition occurs)
-can be done on either: elongated tissue OR actively contracting muscle - ✔✔6. Quick
Stretch/Stretch Stimulus
-amount of resistance facilitates a smooth/coordinated effort throughout desired range
of motion
-must be FACILITORY, not INHIBITORY
-reinforces the awareness of movement patterns, to strengthen and improve
coordination
-types of contractions to restore normal function
--> concentric
--> eccentric
--> isotonic - ✔✔4. Appropriate Resistance
-assessed prior to attempting gait
-purpose: symmetrical posture with alignment of trunk and pelvis upright prior to gait
-which principle can be used to increase stability? --> Approximation
-verbal cue: "stand tall, squeeze your buttocks together" - ✔✔pre-gait/gait activities:
standing approximation
-CNS excitation/overflow directed toward a treatment goal
-demand to one body part can facilitate recruitment of another part
, -what PNF principle is associated with this principle? --> "strong influence the weak" -
✔✔7. Irradiation
-components of movement (also consider associated plane):
--> flexion and extension (sagittal)
--> abduction and adduction (frontal)
--> internal rotation and external rotation (transverse)
-functional patterns = trunk + extremities moving together in spiral/diagonal patterns
-patterns are named for the END position of movement - ✔✔9. Patterns of Facilitation
-essential tool to restore and improve motor control
-total body movement: stimulates joint, muscle, and cutaneous receptors as well as
vestibular system and reticular formation
-purpose:
--> improves arousal and alertness
--> decrease abnormal tone and increase tone (in hypnotic/ataxic patients)
--> improves "awareness"
--> promotes balance
--> improve coordination
--> improve strength and function - ✔✔Rolling: essentials
-in order to take the first step, patients must stabilize in standing and weight shift onto
forward limb, the swing phase must be facilitated to bring the leg forward
-remember: sometimes the best resistance is assistance
-purpose:
--> to teach forward movement of stance leg
--> teach stepping movement of swing leg
--> increase mobility superimposed on stability
-verbal cue: "aaaaaaaaaand step" or "take a high step"
