Development and Application of the WFS-175: A Novel Multidimensional Score for Wrist Function

Abstract

Purpose

We present a novel protocol for wrist function assessment that integrates both objective factors (range of motion and grip strength) and subjective domains (pain, motor function, and quality of life) into the composite Wrist Function Score - 175 (WFS-175) score.

Methods

The protocol consists of three main steps: (1) data collection, which involves measuring the wrist range of motion in six directions using a goniometer and grip strength, including maximum strength, endurance, and recovery, using a Jamar dynamometer, alongside concurrent subjective assessment with a standardized questionnaire; (2) standardization of all data onto a unified scoring scale, applying a linear formula to calculate the total WFS-175 score (maximum 175 points), with the following components: range of motion (30 points), grip strength (40 points), pain (25 points), motor function (40 points), and quality of life (40 points); and (3) input of results into the AppSheet/Google Sheets system, which provides automated calculation, storage, reporting, and graphical visualization for longitudinal tracking of functional recovery.

Results

This protocol yields a standardized assessment form that enables precise calculation of the WFS-175 score. It integrates muscular endurance and recovery measures and fully digitalizes the workflow.

Conclusions

Initial applications show that the WFS-175 score effectively evaluates wrist function and tracks recovery over time. For example, a postoperative patient scored 164/175, indicating excellent recovery.

Clinical relevance

The WFS-175 protocol offers a novel and digital-ready solution for standardized wrist function assessment. By combining objective and subjective measures in one scoring system, it enhances sensitivity and supports clinical decision making in modern rehabilitation.
