The Effectiveness of Information and Relaxation on Pre-procedural Block Anxiety and Procedural Discomfort During Medial Branch Block (TIRAP)

Patient presenting to chronic pain clinics frequently undergo diagnostic and therapeutic spinal injections as part of their treatment. These procedures can cause significant level of apprehension in patients, which can lead to increased procedural times, increased procedural pain and reluctance to continue with the treatment program. It appears that certain interventions could reduce the anxiety and catastrophization levels and modify pain perception during medical procedures. The investigators therefore sought to evaluate the effect of a single 30 minutes information session which includes relaxation training administered 5 to 6 days before the nerve block procedure on patient's anxiety and catastrophization levels prior to the procedure and pain scores during the procedure, as well as the overall level of satisfaction with care received.

Further study details as provided by McGill University Health Center:

Primary Outcome Measures:
  • Change in the anxiety level prior to the nerve block as per the state trait anxiety questionnaire [ Time Frame: 5-7 days (Second visit and Day of block) ]

Secondary Outcome Measures:
  • Perceived pain as measured by NRS (numerical rating scale) [ Time Frame: Throughout the study (Baseline, day of block and 1 month after) ]
  • Unchanged catastrophization level [ Time Frame: Baseline and day of block ]
  • Satisfaction level of the overall experience [ Time Frame: Day after the block ]
  • Ease of performing the nerve block [ Time Frame: Day of block ]
