Spasticity Terminator: How Shockwave Technology "Unlocks" Elbow Joints
Introduction
Elbow spasticity, a common motor dysfunction, severely impacts patients' quality of life and work capacity. While traditional treatments have limitations, shockwave technology, as an innovative physical therapy, has demonstrated unique value in treating elbow spasticity. This article systematically elaborates on the mechanisms of action, clinical applications, and recent research progress of shockwave technology in this field.
Mechanisms of Action
- Biomechanical Effects: Shockwaves deliver controlled stimulation to tissues through specific mechanical wave frequencies, altering local tissue tension balance and regulating muscle contraction-relaxation cycles.
- Microcirculation Improvement: Research (Wang et al., 2022) indicates that shockwaves promote the release of local angiogenic factors, improving tissue perfusion and providing an optimized metabolic environment for spastic muscles.
- Neuromodulatory Function: Shockwaves can influence γ-motor neuron activity (Lee & Chen, 2023), reducing muscle spindle sensitivity and alleviating abnormal muscle tension at the neuromodulatory level.
Clinical Protocol
- Parameter Selection:
- Energy Flux Density (EFD): 0.10−0.25mJ/mm2
- Frequency: 4−6Hz
- Interval: 5–7 days (3–5 sessions per course)
- Localization: Utilizing dynamic palpation combined with ultrasound guidance to accurately target spastic muscle bundles and trigger points.
- Combined Therapy: Concurrent progressive stretching exercises (Smith et al., 2021) are recommended to enhance the efficacy of standalone ESWT.
