The Relationship of the Joint Blockage and Muscle Spasm

NCT07264530 | Completed

• 1 other identifier: Svobodova, Piriformis
• Study Type: interventional
• Target: 40
• Locations: 1 country
• Sites: 1

Brief Summary

An interventional study aimed at verifying the effect of sacroiliac joint blockage on changes in piriformis muscle tension. The study was conducted on 40 subjects, both male and female. Physical therapy methods were used to diagnose muscle tension as a diagnostic tool, along with a visual analogue scale. The intervention was performed using manual mobilisation techniques commonly used in clinical practice. The effectiveness was verified using the same physical therapy diagnostic tool as at the beginning. The entire research process is time-consuming, taking up to 1 hour per examinee.

Conditions

NO DECOMPENSATED ILLNESS; Muscle Cramps; Joint Dysfunction

Keywords

joint blockage; muscle spasm; muscle irritability

Outcome Measures

Primary Outcomes (1)

• Changing of piriformis muscle irritability

  After removing the sacroiliac joint blockage, the irritability threshold of the piriformis muscle increases and its painfulness decreases. The reduction in pain will be evident based on instrumental measurements using the Beauty-line device and palpation examination.

  one hour at all

Study Arms (2)

Experimental investigated group

EXPERIMENTAL

Group to which the mobilization technique will be applied to the sacroiliac joint according to "Cluster of Lasslet"

Procedure: Mobilization technique for sacroiliac joint

Control non-investigated group

NO INTERVENTION

A control group that undergoes an initial examination but subsequently receives no therapy. After 30 minutes of quiet rest, it is examined again.

Interventions

Mobilization technique for sacroiliac joint PROCEDURE

The subject lies on their stomach, mobilization maneuvers are performed, a total of 4 maneuvers according to the recommended "Cluster of Lasslet" procedure for the sacroiliac joint.

Experimental investigated group

Eligibility Criteria

• Age: 18 Years - 60 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• palpation sensitivity of the piriformis muscle in the piriformis line,
• limited joint play of the sacroiliac joint,
• pain in the lower back, groin, perineum, buttocks, or hips, tenderness in the sacrum,
• pain or weakness during resisted abduction at 90° flexion in the hip joint,
• positive piriformis sign, positive Freiberg's test, positive Trendelenburg's test, or positive Pace's abduction test.
• At least 50% of the accompanying signs of sacroiliac joint blockage must be present in each subject.

You may not qualify if:

• acute (primarily infectious) diseases,
• persons in acute condition after an accident,
• persons recovering from an accident/illness

Model Details: A group of suitable subjects (n=40) is divided into an experimental group and a control group (n=20). All subjects meet the study's inclusion criteria. All subjects undergo the same initial examination, including palpation of the piriformis muscle, joint play of the sacroiliac joint, and a visual analogue scale. The experimental group is treated with mobilisation techniques and left to rest for 30 minutes. The control group receives no mobilisation intervention and is only left to rest for 30 minutes. Subsequently, an exit examination identical to the entrance examination is performed. The results are entered into Excel tables and further processed using statistical methods.
