High-velocity, low-amplitude spinal manipulation (HVLA-SM) shows mixed neuromuscular responses. More rigorous research is needed to understand its mechanisms, despite its common use for musculoskeletal pain.
Area of Science:
- Neuromuscular physiology
- Manual therapy research
- Musculoskeletal rehabilitation
Background:
- Clinical use of spinal manipulation for musculoskeletal pain has significantly increased.
- HVLA-SM is recommended by global guidelines for conservative pain management.
- Mechanisms of action for HVLA-SM remain poorly understood.
Purpose of the Study:
- To review evidence on direct neuromuscular responses to HVLA-SM.
- To identify gaps in mechanistic knowledge of neuromuscular responses to HVLA-SM.
- To foster interprofessional dialogue and collaborative research.
Main Methods:
- Literature overview of studies published between 2000 and December 2024.
- Searched PubMed, CINAHL Ultimate, and EMBASE databases.
- Included studies focused on neuromuscular responses (EMG, muscle thickness, strength, reflexes, EEG, evoked potential) to thrust HVLA-SM, excluding non-HVLA-SM techniques and patient-centered outcomes.
Main Results:
- Neuromuscular findings related to HVLA-SM were often mixed.
- Evidence is accumulating for specific neuromuscular responses as study rigor increases.
- Limitations include small sample sizes and non-standardized HVLA-SM delivery.
Conclusions:
- Current evidence on neuromuscular responses to HVLA-SM is inconclusive due to study limitations.
- Further research is needed to clarify the direct neuromuscular effects of HVLA-SM.
- Standardization of HVLA-SM delivery and larger sample sizes are crucial for future studies.

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
Motor Unit Stimulation
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...
Muscle Stimulation Frequency
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...
Skeletal Muscle Relaxants: Therapeutic Uses
Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....
