Handheld Dynamometer During Awake Craniotomy Pilot

Use of Handheld Dynamometer As a Novel Tool to Assess Motor Function During Awake Craniotomy for Brain Lesions Located Within or Adjacent to the Motor Cortex: a Single-Center Pilot Study

The primary purpose of this study is to assess the feasibility, safety and reliability of the use of handheld dynamometry in evaluating intraoperative motor function for patients undergoing awake craniotomy for the resection of brain lesions located within or adjacent to the motor cortex.

Inclusion Criteria:

• Patients ≥ 18 years old.
• Primary or Recurrent Brain tumors
• Single brain lesion
• Lesion within or adjacent to the motor cortex- Lesion located within the primary or supplementary motor area (Verified by preoperative fMRI and DTI).

Exclusion Criteria:

• Patients < 18 years old.
• Major comorbidities (congestive heart failure, severe chronic obstructive pulmonary disease, morbid obesity, obstructive sleep apnea).
• Patients with cognitive, intellectual or psychiatric impairment that could affect the capacity of following instructions evaluated during preoperative neuropsychological testing.
