Purpose: This transitional movement assessment also assesses dynamic flexibility, core strength, balance, and overall neuromuscular control. A reliable and valid measure of lower extremity movement patterns.
Knee valgus has shown to be influenced by decreased hip abductor and hip external rotation strength, increased hip adductor activity, and restricted ankle dorsiflexion. This suggests that movement impairments observed during the transitional movement assessment may be the result of alterations in available joint motion, muscle activation, and overall neuromuscular control.
Procedure: Client stands with hands on the hips, eyes focused on an object straight ahead. Foot pointed straight ahead. The foot, ankle, knee, and the lumbo-pelvic-hip complex in a neutral position.
Movement: 1) Have client squat to a comfortable level and return to starting position.
2) Perform up to 5 reps before switching sides.
Views: View the knee from the front. Knee should track in line with the foot (2nd and 3rd toes).
Compensation: Does the knee move inward (adduct and internally rotate)?
Record findings, then refer to Table on pg 146 to determine overactive and underactive muscles.
Sensory receptors responsible for sensing distortion in body tissues.
-Respond to outside forces (touch, pressure, stretching, sound waves, motion) and transmit impulses through sensory nerves, which enable us to detect touch, sounds, and motion of body. Also monitor position of muscles, bones, joints (proprioception)
-Located in muscles, tendons, ligaments, joint capsules; include muscle spindles, Golgi tendon organs, and joint receptors
Three levels of training: stabilization, strength, power
-Exercises do not involve much joint motion
-Exercises improve landing mechanics, postural alignment, and reactive neuromuscular efficiency
Exercise examples: Squat jump with stabilization, Box jump-up with stabilization, Box jump-down with stabilization, Multiplanar jump with stabilization
**When performing these, hold the landing for 3 to 5 seconds and make necessary adjustments to correct any faulty postures before repeating the exercise
-Exercises involve more movement through a full range of motion, requiring greater specificity, speed, and neural demand
-These movements further improve dynamic joint stabilization, the rate of force production, and eccentric neuromuscular efficiency.
Exercise examples: Squat jump, Tuck jump, Butt kick, Power step-up
**These exercises should utilize a repeating (medium) tempo
-Exercises are performed as fast and explosively as possible
-They improve rate of force production, reactive strength, dynamic neuromuscular efficiency, and optimal force production
Exercise examples: Ice skaters (aka skater jumps), single-leg power step-up, proprioceptive plyometrics
High blood pressure, a common medical disorder.
-Consistently elevated arterial blood pressure, which, if sustained at a high enough level, is likely to induce cardiovascular or end-organ damage.
A client is considered to have this if they have had two or more resting blood pressure assessments made on separate days that are ≥140 or ≥90 mm Hg, OR if they are currently taking medication to control blood pressure.
Most common causes of this: smoking, a diet high in fat (particularly saturated fat), and excess weight.
Health risks of this include: increased risk for stroke, cardiovascular disease, chronic heart failure, and kidney failure
