Q

How can tandem walking help patients with severe ataxia?

A

Assists them in walking along a straight line to improve balance.

20
Q

What exercises help vaulting with foot drop/slap?

A

Bending over a counter while working on hip flexion and ankle dorsiflexion, stepping over objects.

21
Q

How do Nordic poles assist with gait training?

A

They improve gait rhythm and promote better coordination

22
Q

What is the purpose of ‘choo-choo train’ walking?

A

Retrains the brain for coordinated trunk rotation, arm swing, and normal gait patterns with Nordic poles.

23
Q

What is dysdiadochokinesia?

A

The impaired ability to perform rapid, alternating movements.

24
Q

What is adiadochokinesia?

A

The complete inability to perform rapid, alternating movements.

25
What two exercises can be used to assess dysdiadochokinesia?
Toe tapping and sliding the heel up to the knee and back down
26
What coordination exercises can be used for a patient with ethanol-induced hemiataxia?
Two exercises in sitting and two in standing to improve right lower extremity coordination
27
What is the purpose of hand-in-hand walking for patients with left-sided neglect?
Helps them become aware of their neglected side
28
How can patients with left-sided neglect practice spatial awareness?
Spotting objects on the left side in the hallway and avoiding obstacles placed strategically.
29
What is the first and second step in training a patient with Pusher Syndrome before walking?
Teach weight-shifting onto the UNAFFECTED side by leaning toward a wall. Have the patient lean towards the UNAFFECTED side and lift the AFFECTED leg for 5 seconds.
30
How is assisted walking performed for a patient with Pusher Syndrome?
PTA supports the AFFECTED side while giving verbal and tactile cues to shift weight toward the UNAFFECTED side
31
What is circumduction gait?
A gait pattern where one leg moves straight forward while the other swings out to the side in an arc.
32
What are common causes of circumduction gait?
- Weakness in hip flexors or knee flexors - leg length discrepancy - reduced knee mobility.
33
What is hip hike and vaulting gait?
Hip hike: Lifting the hip to clear the foot. Vaulting: Pushing off with the stance leg to help the other leg clear the ground.
34
What are the main causes of hip hike and vaulting gait?
- Weak hip/knee flexors - leg length discrepancy - reduced dorsiflexion
35
What is toe catch gait?
A gait pattern where the toes drag and catch the ground due to weak dorsiflexors
36
What are treatment options for toe catch gait?
- Therabands for hip flexion - strengthening exercises - bracing - adaptive shoes - taping the toe for sliding - AFOs
37
What is steppage gait?
A high stepping gait with a slapping sound due to weak dorsiflexors, causing the foot to drop
38
What are common causes of steppage gait?
- Weak foot and ankle dorsiflexors - sensory loss - neurological conditions such as peripheral neuropathy
39
What is an initial contact with flat foot and stiff knee gait pattern?
A gait where the foot lands flat on the ground, and the knee remains locked without flexing
40
What are the main issues in a stiff knee gait?
Lack of knee flexion, poor shock absorption, and difficulty with propulsion.
41
What is knee hyperextension gait?
A gait pattern where the knee snaps backward due to weak hamstrings.
42
How can knee hyperextension be managed?
- Encouraging knee flexion when walking - using straps around the knees during exercises - practising sit-to-stand partway - strengthening hamstrings and quadriceps together
43
What is a crochet gait pattern?
- Seen mostly cerebral palsy (CP) - where the knees remain flexed - hips abducted - the patient appears to be in a squatting position
44
What is scissoring gait?
- legs cross over midline while walking - often due to tight hip adductors or weak glute muscles.
45
What are treatment options for scissoring gait?
- Stretching tight hip adductors - strengthening glutes and hip abductors - gait training.
