Proprioceptive Neuromuscular Facilitation Protocol for Thumb Osteoarthritis: A Pilot Study

Area of Science:

• Orthopedics
• Rehabilitation Science
• Sports Medicine

Background:

• Thumb carpometacarpal (CMC) joint osteoarthritis (OA) commonly causes joint instability and proprioceptive deficits.
• Proprioception is crucial for effective rehabilitation in patients with CMC joint OA.
• Early-stage OA management often focuses on pain reduction and functional improvement.

Purpose of the Study:

• To assess the efficacy of a proprioceptive training program for pain and function in early-stage thumb CMC joint OA.
• To evaluate the impact of proprioceptive training on joint stability and sensory feedback.
• To determine if targeted proprioception exercises enhance outcomes beyond standard care.

Main Methods:

• A double-blind, randomized controlled pilot study with a pretest/posttest design.
• Participants with Grade I/II thumb CMC OA and significant pain were assigned to standard care or standard care plus proprioceptive training.
• Outcome measures included lateral pinch strength, pain during activities, and joint position sense (JPS) testing.

Main Results:

• Both groups showed significant pain reduction and increased lateral pinch strength (large effect size).
• No significant difference in pain or strength was observed between the groups.
• The proprioceptive training group demonstrated a significant improvement in JPS (large effect size) compared to the control group (trivial effect size).

Conclusions:

• Proprioceptive training significantly enhanced proprioceptive function in individuals with thumb CMC joint OA.
• The findings suggest that proprioceptive training may be a valuable addition to hand therapy for this condition.
• Further research with larger sample sizes is warranted to confirm these preliminary results.
