Mapping Recovery: The RADAR Scale, Born From a Clinical Round

Area of Science:

• Orthopedics
• Neurology
• Rehabilitation Medicine

Background:

• Nerve injuries often present challenges in quantifying functional recovery.
• Electrophysiological data may not always align with a patient's perceived functional improvement.
• A need exists for patient-centered tools to complement objective diagnostic measures.

Purpose of the Study:

• To introduce the RADAR (Reach, Activities, Dexterity, Awareness, Role) scale, a novel patient-centered assessment tool.
• To quantify functional recovery in patients with nerve injuries.
• To facilitate communication between patients and clinicians, especially when functional and electrophysiological data diverge.

Main Methods:

• Development of the RADAR scale, a 10-item, 50-point tool for assessing functional recovery.
• Retrospective application of the RADAR scale to a single patient with radial nerve palsy post-humeral shaft fracture.
• Comparison of RADAR scale scores with serial electromyogram (EMG) reports of motor nerve amplitude.

Main Results:

• The patient's RADAR scale score improved from 0 preoperatively to 50 at 28 weeks, reflecting observed functional gains.
• Electromyogram data showed minimal improvement in motor nerve amplitude, indicating a dissociation between function and electrophysiological findings.
• The RADAR scale demonstrated a close tracking of the patient's functional progress.

Conclusions:

• The RADAR scale effectively quantifies patient-centered functional progress in nerve injury rehabilitation.
• The scale can identify functional improvements missed by standard electrophysiological tests.
• The RADAR scale has potential to enhance communication and personalize care, warranting further validation in larger studies.
