Chapter 10 - Mobility Assessments Flashcards
ROM
The amount of motion available at a specific joint.
Flexibility
The present state or ability of a joint to move through a range of motion
Mobility
The entire available range of motion at a joint and the body’s neuromuscular control of that motion.
Active motion
The amount of motion obtained solely through voluntary contraction.
Passive motion
The amount of motion observed without any assistance from an external force.
Mobility Restriction
The inability to move a joint through what should be its full range of motion.
Mobility assessments provide the Corrective Exercise Specialist with additional clues when answering the following questions
- Do overactive/shortened or underactive/lengthened muscles contribute more to the observed movement impairment?
- Among the overactive/shortened muscles listed, are there specific ones that play a more prominent role in the movement impairment?
- Is the corrective exercise program improving the mobility of the client or athlete over time?
Ankle dorsiflexion (weight bearing lunge test)
Client position: Standing in a lunge position with shoes off, feet straight, and heels planted firmly on the ground and toes positioned approximately 2 inches away from the wall
Type of motion: Passive (forward test leg is relaxed)
Target motions: The client’s front leg (test leg) lunges toward the wall, using hands for support, until the ankle and foot reach their end-range. The back foot is positioned to support the overall posture.
Ankle dorsiflexion (weight bearing lunge test): verbal instructional cues
Keep your front foot straight and heel planted firmly on the ground, then lunge forward until the first stretch sensation is felt in the back of your front leg. Avoid pushing with your back leg/foot
Ankle dorsiflexion (weight bearing lunge test): Assessment results
Normal mobility: The client is able to touch the wall with the forward-bending knee without compensation.
Restricted dorsiflexion: The client is unable to touch the wall or displays compensations such as heel lift, foot external rotation, arch collapse, or knee valgus.
Overactive/shortened: Gastrocnemius and soleus
First MTP ( Great Toe) Extension
Client position: Standing or seated
Type of motion: Active Target motions: The client moves the right big toe upward (extension) as far as possible while keeping other toes and foot stable, and then performs the same movement with the left big toe.
First MTP ( Great Toe) Extension: Verbal instructional cues
Move your right big toe upward as far as possible while keeping everything else still, then repeat on your left side
First MTP ( Great Toe) Extension: Assessment results
Normal mobility: The client is able to extend the big toe above other toes without compensation.
Restricted MTP extension: The client is unable to extend big toe above others or displays compensations such as movement through the other toes or accessory movement through the foot and/or tibia.
Overactive/shortened: Flexor hallucis longus
Active knee flexion test (Duncan Fly Test)
Client position: Lying prone on a table
Type of motion: Active
Target motions: The client actively flexes the right knee as far as tolerable, then performs with the left knee.
Active knee flexion test (Duncan Fly Test): Verbal instructional cues
Verbal instruction: “Bend your right knee as far as you can and hold, then repeat on the left side.
Active knee flexion test (Duncan Fly Test): Assessment results
Normal mobility: The client can bring the foot close to or touching their buttocks without compensation.
Restricted knee flexion: The client is unable to reach the desired ROM target or displays compensations such as the test hip lifting off the table.
Overactive/shortened: Quadriceps complex
Active knee extension test
Client Position: Lying supine on a table
Type of motion: Active
Target motion: The client holds the test leg in 90 degrees of hip flexion and knee flexion. The pelvis should not posteriorly rotate or lumbar spine flatten. The client actively extends the knee while keeping the hip stable. The client’s other leg is straight and relaxed on the table.
Active knee extension test: Verbal instructional cues
Verbal instructions: “Lift your right thigh to 90 degrees and hold your leg with your hands behind your knee, then actively straighten your knee as far as you can. Repeat on your left side.”
Active knee extension test: Assessment results
Normal mobility: The client can extend the knee nearly or completely straight without compensation.
Restricted knee extension: The client is unable to extend their knee to the desired ROM or displays compensations such as the test thigh moving into extension (back toward the table) or movement in the opposite leg.
Overactive/shortened: Hamstrings complex
Lumbar flexion and extension
Client position: Standing with knees straight and feet hip-width
Type of motion: Active
Target motions: The client forward bends (flexion) and attempts to touch their toes, then arches backward (extension) as far as possible while keeping their neck in a neutral position.
Lumbar flexion and extension: Verbal instructional cues
“Bend your trunk forward as far as you can, try to touch your toes, and then arch the back as far as you can while keeping the head and neck straight, knees straight and the feet in place.”
Lumbar flexion and extension: Assessment results
Normal mobility:
Flexion: The client is able to touch the toes or floor without compensation.
Extension: The client arches the back enough where their shoulders pass their hip joints without compensation.
Restricted flexion: The client is unable to reach their toes or floor or displays compensation such as accessory motion in the lower extremity (e.g., knee flexion).
Overactive/shortened: Erector spinae
Restricted extension: The client is unable to reach the target ROM or displays compensations such as accessory motion in other segments of the spine such as cervical extension.
Overactive/shortened: Rectus abdominis, internal obliques, and external obliques
Hip Extension, Hip Adduction, and Knee Flexion (Modified Thomas Test*)
Client position: Lying supine at end of a table with both knees bent over the edge of the table
Type of motion: Passive
Target motion: The client holds the nontesting knee to their chest, putting that hip in a maximally flexed position. The lumbar spine and pelvis are flat on the table. The test leg is relaxed on the table. The Corrective Exercise Specialist looks for three movements of the test leg and then repeats on the other side:
Hip extension: Assesses psoas length
Hip abduction angle: Assesses tensor fascia latae length
Knee flexion: Assesses rectus femoris length
Hip Extension, Hip Adduction, and Knee Flexion (Modified Thomas Test*): Verbal instruction
“Sit at the edge of the table, then lay back with both knees bent off the table. Grab your left leg at your knee and pull toward your chest and keep your right leg on the table completely relaxed. Repeat the sequence with the other leg.”
Hip Extension, Hip Adduction, and Knee Flexion (Modified Thomas Test*): Assessment results
Normal mobility:
Hip extension: The test side hip and thigh lay flat on the table in line with the torso without compensation.
Hip adduction: The femur rests in a straight line with the torso (not abducted) without compensation.
Knee flexion: The knee hangs naturally at 90 degrees off the table edge without compensation.
Restricted hip extension: Test thigh lifts off the table.
Overactive/shortened: Psoas and rectus femoris
Restricted hip adduction: Test thigh is abducted and not in line with the torso.
Overactive/shortened: Tensor fascia latae
Restricted knee flexion: Test knee is slightly extended and not at 90 degrees.
Overactive/shortened: Rectus femoris
Hip Abduction and External Rotation (Adductor Test)
Client position: Lying supine on a table
Type of motion: Passive
Target motions: The client lies supine with the test hip and knee bent to 45 degrees with the foot placed on the medial portion of the opposite leg, between the thigh and shin as needed to achieve the correct angles. The nontesting leg is straight. The client passively relaxes the test leg to let it fall toward the table. This is repeated on the opposite side.
Hip Abduction and External Rotation: Verbal instructions
“Bend your right leg at the hip and knee to bring your foot against the opposite shin and then allow your leg to passively relax. Repeat on your other side.”
Hip Abduction and External Rotation: Assessment results
Normal mobility: The hip and knee on the testing side lay flat on the table without compensation.
Restricted abduction: The client is unable to lay the test leg flat on the table or displays compensations such accessory motion in the opposite side of the pelvis (e.g., lifts off table).
Overactive/shortened: Hip adductor complex
