Lifting injuries frequently affect key stabilizer muscles, including the multifidi, obliques, quadratus lumborum, and glutes, which are essential for proper posture and movement. When these muscles are strained or weakened, they can lead to chronic pain, restricted mobility, and a higher risk of re-injury.
Identifying Weak Muscles: Key Tests
To determine which muscles are weak, specific muscle tests can be performed:
- Multifidi Test: To assess multifidi strength, have the individual perform a bird-dog exercise. Difficulty stabilizing the spine during this movement may indicate weak multifidi.
- Oblique Strength Test: The obliques can be tested with a side plank. If the individual struggles to hold this position on one side, it may indicate a weakness in the obliques.
- Quadratus Lumborum (QL) Test: To test the QL, the individual lies on their side and lifts their top leg while keeping the pelvis stable. Difficulty performing this motion can indicate a weak QL.
- Gluteus Medius Test: A hip abduction test, where the individual lifts their leg sideways, can reveal gluteus medius weakness if there’s difficulty keeping the leg lifted and stable.
- Gluteus Maximus Test: To test the gluteus maximus, have the individual perform a prone leg lift. The inability to lift the leg without hip rotation may suggest weakness.
Electroacupuncture for Muscle Recovery and Pain Relief
Electroacupuncture at targeted frequencies (2-5 Hz for acute pain, 50-100 Hz for chronic pain) can relieve pain, relax tense muscles, and aid recovery by stimulating these specific muscles. Patients can recover strength and mobility faster by identifying weak muscles and using electroacupuncture, improving stability and preventing future lifting injuries.
