Official title
The Effect of Unloading Maneuvers During Spinal Flexion Exposure
Overview
An experimental study, which will aim to investigate the acute effects of unloading maneuvers during an intermittent spinal flexion protocol on changes in trunk mechanical and neuromuscular properties.
Detailed description
Our experimental study will include 30 participants. All participants will complete a 60-min intermittent spinal flexion protocol. During rest periods within the protocol, the participants from the intervention group will perform unloading maneuvers for the lumbar spine. Measurements of trunk mechanical and neuromuscular properties. will be performed prior to and following the 60-min protocol.
Interventions
- Other Unloading maneuvers
Participants will perform unloading maneuvers four times with 15 min of spinal flexion protocol in between. The intervention will include self traction on a box (5 s) and sustained standing trunk extension (8 s). Both maneuvers will be repeated twice at each timepoint.
Primary outcome measures
- Change in muscle stiffness [Time frame: 90 minutes]
Secondary outcome measures (4)
- Change in range of motion [Time frame: 90 minutes]
- Change in seated spinal height [Time frame: 90 minutes]
- Change in lumbar lordosis angle [Time frame: 90 minutes]
- Change in trunk extension maximal strength [Time frame: 90 minutes]
Eligibility criteria
Inclusion criteria
- Occupational workers with a predominantly non static job (e.g. combination of sitting and standing)
Exclusion criteria
- History of chronic low back pain
- Episode of acute low back pain
- Hip injury in the past six months
- Previous spine, pelvis or hip surgery
- Hypermobility, diagnosed with the Beighton score
- High intensity resistance training (> 75 % of 1 repetition maximum) more than two times a week
- Sporting or recreational activities, that include repetitive spinal flexion or maintenance of a flexed posture (for example cycling or rowing).
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
