The Immediate Effects of Spinal Manipulative Therapy on Kinetic and Kinematic Symmetry.
A study testing Spinal Manipulative Therapy in people with Asymptomatic Condition, run by University of Lisbon at 1 site in Portugal.
Trial summary
Athletes have been exposed to an ever increasing training load and subsequent biomechanical overload due to a constant demand for performance enhancement. As a result, it is observed an increased rate of musculoskeletal problems, including spinal biomechanical dysfunctions that are often asymptomatic. Read more about this study

- Ages 18 to 35 years
- All sexes
- Healthy volunteers accepted
- Adult
Who may be able to join
- The inclusion criteria for sample followed the assumptions below:
- All young student participants had to be of both sexes, age between 18-35 years old.
- All participants had to be pain free or asymptomatic, with regards to low back pain, in order to create homogeneity within the study sample.
- All participants had to have at least a minimal score, (low level) of physical activity, evaluated by (IPAQ) questionnaire (International Physical Activity Questionnaire). This was done on the argument that the minimal score, already shows that the participants were minimally physically active. This also contributed in an indirect way to assure a certain degree of sample homogeneity, scoring the minimal level of physical activity to include in the study;
- All participants were required to show the subluxations or vertebral dysfunctions in their lumbar spine, detected by motion palpation. Through the purposive sampling, was allowed participants to officially take part in the study.
Who cannot join
- The exclusion criteria for sample followed the assumptions below:
- Participants who received medical, surgical or in addition manual interventions prior or during the study, were immediately excluded.
- Participants who presented with any contraindications to manipulation on spine, which included but was not limited to osteomyelitis, tuberculosis, infectious arthritis, disc extrusion, hemangioma, vertebral malignancy and advanced spondylolisthesis
- Participants who have participating of sports competitions or change in training routine during the collecting data, was immediately withdraw from the study.;
- Participants with no vertebral dysfunction in the palpated lumbar joints were excluded of the study;
- Participants who did not sign the informed consent form, or not agree of the conditions, or did not have conditions to compromise with the schedule, were immediately withdraw from the study.

About this study
Official title: Immediate Effects of Spinal Manipulative Therapy (SMT) on Kinetic and Kinematic Symmetry on Functional Performance Tests: a Test-retest, Single-blinded, Randomized Controlled Trial.
Athletes have been exposed to an ever increasing training load and subsequent biomechanical overload due to a constant demand for performance enhancement. As a result, it is observed an increased rate of musculoskeletal problems, including spinal biomechanical dysfunctions that are often asymptomatic. These dysfunctions are believed to negatively influence a wide range of mechanical and physiological parameters such as muscle strength, range of motion, and symmetry, what could potentially influence sports performance.
Spinal Manipulative Therapy (SMT) is a safe and effective therapy for musculoskeletal disorders that has been increasingly utilized in sports. SMT purpose is to correct spinal joints biomechanical dysfunctions using a high-velocity, low-amplitude movement, applied at the paraphysiological space, beyond the passive joint range of motion.
Kinetic and kinematic symmetry can be measured in commonly utilized physical functional tests often used as indicators of athlete's performance. Symmetry Index calculation is used to verify bilateral asymmetries in static and dynamic tests.
Read the detailed description
Therefore, the objective of this randomized controlled trial study is to measure the immediate effects of lumbar SMT on kinetic and kinematic symmetry of asymptomatic athletes, through of the use of three commonly used functional tests: Static posture, Free Squat, and Countermovement Jump (CMJ) are often used as indicators of athlete's performance. These quantitative data is important to assess training effectiveness and prevention/ rehabilitation programs outcomes. To our knowledge this is the first study on literature that measured the immediate effects of SMT on kinetic and kinematic symmetry.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Spinal Manipulative TherapyProcedure or surgery
Also called Movement Disorders/therapy, Spinal Manipulation
Lumbar (SMT) was performed using Diversified techniques, aiming to correct vertebral dysfunctional lumbar segments. Participants were asked to lay down prone on, to perform spinal motion palpation analysis was in order to evaluate the presence of dysfunction in vertebral segments of lumbar spine.
SHAMProcedure or surgery
Also called Control Group
The "SHAM" (pre-load positioning SMT) was performed with participant body positioning in the lateral position, as the SMT intervention. The doctor followed the participant through the same position of (SMT) intervention, using the maintenance of set-up position, but no manipulative thrust was delivered. The therapist applied minimal pressure and slid their hands across the skin to mimic the manipulative trust. The position was maintained 30 seconds on each side, and none of force or researcher body weight were putted in this procedure, only minimal pressure common to stabilize the set up position of (SMT).
| Study group | Role | What they receive |
|---|---|---|
| Spinal Manipulative Therapy | Experimental | The participants assigned to the intervention group received the procedure Lumbar (SMT) was performed after baseline measurements, using Diversified techniques, aiming to correct vertebral dysfunctional segments after clinical assessment. Participants were asked to lay down prone on, to perform spinal motion palpation analysis was performed in order to evaluate the presence of dysfunction in vertebral segments of lumbar spine. Receives: Procedure: Spinal Manipulative Therapy |
| Sham pre-load positioning SMT | Sham comparator | The participants assigned to the control group received the procedure "Sham" (pre-load positioning MVT). The Sham (SMT) was performed with participant body positioning in the lateral position, as the SMT intervention. The doctor followed the participant through the same position of (SMT) intervention, using the maintenance of set-up position, but no manipulative thrust was delivered. The therapist applied minimal pressure and slid their hands across the skin to mimic the manipulative trust. The position was maintained for approximately 1 minute in total, 30 seconds on each side, and none of force or researcher body weight were putted in this procedure, only minimal pressure common to stabilize the set up position of (SMT). Receives: Procedure: SHAM |

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Kinetic Symmetry (Lower Limbs Ground Reaction Forces) (time frame: 5 min after lumbar SMT intervention). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03361592, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 May 2018; AzTrials last refreshed its copy on 7 Nov 2026.
