The purpose of this study is to develop a measure - the needle torque test - capable of detecting connective tissue abnormalities associated with musculoskeletal disorders.

Connective Tissue Musculoskeletal Pain

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Cross-Sectional
Official Title: Automated Connective Tissue Torque Sensor

Further study details as provided by Robert Davis, Stromatec, Inc.:

Primary Outcome Measures:
  • Number of needle revolutions to achieve threshold torque [ Time Frame: Time zero, 30 minutes and one week ]

Enrollment: 165
Study Start Date: February 2012
Study Completion Date: January 2013
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Healthy controls
Chronic low back pain
restricted hamstrings
systemic scleroderma
joint hyperlaxity

Detailed Description:
Chronic musculoskeletal pain is a source of considerable disability, work absenteeism and health care costs. A major obstacle to the treatment of these conditions is the lack of methods to objectively assess connective tissues and measure the effect of treatments. Needle torque test technology under development in this project will potentially enable objective measurement of connective tissue abnormalities associated with musculoskeletal pain and dysfunction. This could help evaluate the efficacy of various treatments and enhance the objective monitoring of patient progress in clinical practice.
