Evaluation of instruments for measuring grip strength.

Area of Science:

• Biomechanics
• Clinical Measurement
• Rehabilitation Technology

Background:

• Accurate grip strength measurement is crucial for assessing neuromuscular function and guiding rehabilitation.
• Existing grip strength devices vary in precision and clinical applicability.

Purpose of the Study:

• To evaluate the linearity and clinical applicability of three grip strength instruments: the steel spring dynamometer, Martin Vigorimeter, and My-Gripper.
• To determine the most suitable instrument for routine clinical use.

Main Methods:

• Instruments were tested for linearity using a universal testing machine.
• A clinical study involving 100 healthy participants assessed the practical application of each device.
• Data analysis focused on precision, ease of use, and cost-effectiveness.

Main Results:

• The steel spring dynamometer demonstrated insufficient precision for clinical use.
• Both the Martin Vigorimeter and My-Gripper exhibited high precision.
• The My-Gripper was found to be cost-effective, user-friendly, and capable of averaging multiple readings.

Conclusions:

• The My-Gripper is a preferable choice for clinical grip strength assessment compared to the steel spring dynamometer and Martin Vigorimeter.
• The My-Gripper's features facilitate accurate and efficient measurement of grip strength in clinical settings.
