Preliminary Clinical Application of the Muscle Compression Resistance Index (MCRI) Using the BFpress Device: A Physiotherapy Case Report

Abstract

Background: Objective assessment of muscle resistance and muscle spasm in physiotherapy practice remains limited, as clinical evaluation is commonly based on subjective palpation [4, 8]. Compression-based measurement approaches may provide more objective clinical information.

Purpose: To present a preliminary clinical application of the Muscle Compression Resistance Index (MCRI) using the BFpress device in a patient with lumbar muscle spasm following trauma.

Case Description: A 16-year-old female patient presented to a physiotherapy clinic two weeks after a fall accident with a diagnosis of cervical sprain and lumbar muscle spasm. Four physiotherapy sessions were performed, one per week. Muscle resistance was assessed using the BFpress device at the L4–L5 level.

Results: Mean BFpress values increased from 20 kg at the first session to 25 kg at the second and third sessions, and to 32 kg at the fourth session, indicating progressive reduction in muscle resistance.

Conclusion: This preliminary case report suggests that the MCRI may serve as a simple and clinically applicable monitoring index for documenting changes in muscle resistance during physiotherapy interventions.
