Abstract
- Purpose: Neurodevelopmental techniques are commonly used in upper limb rehabilitation, but little evidence supports the facilitation techniques associated with this concept. This exploratory study determined whether a facilitation technique at the triceps muscle affected scapulothoracic muscle activity during reach in healthy participants compared with self-selected posture and reach. The secondary aim was to determine whether muscle activation levels differed between the facilitation technique and the optimized posture or guided movement. We also hypothesized that activity in the scapular stabilizers (lower trapezius [LT] and serratus anterior [SA]) would be increased during the facilitated movement than in the other conditions. Methods: The study included 17 healthy participants (aged 20–70 y). Surface electromyography recorded muscle activity in the upper trapezius (UT), middle trapezius (MT), and LT muscles and in the SA, middle deltoid (MD), and triceps during five performance conditions. We used Friedman’s test to explore differences in muscle activity across conditions and Bonferroni’s post hoc test to explore the differences between conditions. Results: The facilitation technique produced decreased activity in the SA, MD, and triceps muscles ( p < 0.01) compared with the self-executed control condition. Compared with optimized posture with independent reach, facilitated movement again produced similar reductions in MD and triceps activity, with decreased LT activity also noted ( p < 0.01). Lower activity levels were noted during facilitation than during manual guidance, with or without optimized posture, in the UT, MT, ( p < 0.01), SA, and MD muscles ( p < 0.05). Conclusions: Triceps facilitation did not increase scapular stability activity, but the activity levels in several other muscle groups (SA, MD, and triceps) were reduced during triceps facilitation compared with optimized posture or guided movement. Detailed analysis of this technique, including co-registered kinematic data and timing of muscle onset, is needed.
