A Physical Therapist Is Working on Improving Active Wrist Extension

question 7

Multiple Choice

A physical therapist is working on improving active wrist extension and stabilization needed for reach and grasp in a 62 year-old women who is 2 weeks post-stroke.The therapist has decided to apply neuromuscular electrical stimulation (NMES) to the wrist extensors.Which of the following exercise design and electric stimulation parameters would be most effective to address this patient's therapeutic goal?

• A)Electrical stimulation at 30-50 Hz,amplitude at motor threshold,while the patient is engaged in a reaching task requiring wrist extension.
• B)Electrical stimulation at 50-70 Hz,amplitude at motor threshold,while the patient has supported limb in gravity eliminated position in relaxed position on table.
• C)Electrical stimulation at 30-50 Hz,amplitude at sensory threshold,while the patient has arm supported on table top and is practice active ROM of wrist extension.
• D)Electrical stimulation at 20-30 Hz,amplitude at sensory threshold,while the patient is lifting a mug off the table requiring wrist stabilization.
