Lifting With Flexed Lumbar Spine

Lifting With Flexed Lumbar Spine

*Lifting with a flexed lumbar spine often referred to as round back or" hunching "while lifting can increase the risk of lower back injuries .  

* Flexed lumbar spine postures are associated with greater strength and efficiency  than lordotic postures during a maximal lift in pain-free individuals.

*When the lumbar spine is flexed ,the intervertebral discs between the vertebrae may be subjected to uneven pressure, leading to potential disc herniation or strain on surrounding structures.

*Lifting with a flexed lumbar spine disrupts this alignment, compromising the spine's ability to bear loads & safely.

* Proper lifting technique involves bending at the hips & knee s while keeping the back straight, engaging the core muscles for stability.


  1. **Strain on Intervertebral Discs:**

   - Flexing the lumbar spine places increased pressure on the intervertebral discs.

   - This can lead to disc bulges or herniations, causing pain and potential nerve compression.

  1. **Muscle Strain:**

   - Excessive lumbar flexion can strain the muscles of the lower back, especially the erector spinae.

   - Muscle spasms and discomfort are common symptoms.

  1. **Reduced Spinal Stability:**

   - Lumbar flexion compromises the natural curvature of the spine, reducing stability.

   - This instability may contribute to a higher risk of injury.

  1. **Nerve Impingement:**

   - Flexing the lumbar spine can lead to impingement of the spinal nerves, causing radiating pain, numbness, or tingling in the legs.

  1. **Reduced Weight Lifting Efficiency:**

   - Flexing the lumbar spine hinders the ability to lift weights efficiently.

   - It may decrease the effectiveness of strength training exercises and increase the risk of injury.

  1. **Chronic Back Pain:**

   - Prolonged or repetitive lumbar flexion during lifting may contribute to chronic lower back pain.

   - It can impact daily activities and overall quality of life.

  1. **Decreased Range of Motion:**

   - Flexing the lumbar spine restricts the normal range of motion of the lower back.

   - This limitation may affect overall mobility and functional activities.

  1. **Degenerative Changes:**

    - Consistent flexion under load may accelerate degenerative changes in the spine over time.

    - This includes wear and tear on the vertebral joints and discs.

Physical examination during lifting with a flexed lumbar spine involves assessing various aspects.

  1. **Observation:**

   - Note the lifting technique.

   - Observe body posture, looking for signs of lumbar flexion during the lift.

   - Assess any visible discomfort or signs of strain.

  1. **Range of Motion (ROM):**

   - Evaluate the range of motion in the lumbar spine.

   - Check for any restrictions, pain, or discomfort during flexion and extension.

  1. **Palpation:**

   - Palpate the lumbar spine for tenderness, muscle spasms, or any abnormalities.

   - Identify specific areas of pain or tension.

  1. **Muscle Strength and Endurance:**

   - Assess the strength of the lumbar and core muscles.

   - Check for signs of muscle fatigue during repeated flexion movements.

  1. **Neurological Examination:**

   - Evaluate reflexes, especially those related to the lumbar spine.

   - Assess for any sensory changes or abnormalities.

  1. **Functional Movement Assessment:**

   - Evaluate the individual's ability to perform functional movements, such as bending, lifting, and twisting.

   - Identify any compensatory movements or deviations from proper lifting mechanics.

  1. **Postural Assessment:**

   - Analyze overall posture, including alignment of the spine, pelvis, and shoulders.

   - Look for any imbalances or deviations that may contribute to lumbar flexion during lifting. 

Physiotherapy management

1.LASER Therapy

LASER therapy uses a specific wavelength of energy to reduce back pain and begin the healing process. It reduces muscle spasms in the back and stimulates regeneration of the structures in the back. It also improves blood circulation around the injured area, accelerating healing.

2.Transcutaneous Electrical Nerve Stimulation (TENS)

* Transcutaneous electrical nerve stimulation (TENS) is a method of pain relief involving the use of a mild electrical current.

*The electrical impulses can reduce the pain signals going to the spinal cord and brain, which may help relieve pain and relax muscles.


Ultrasound therapy is a noninvasive treatment in which sound waves are used to penetrate soft tissues, increasing blood flow. This can help relieve pain, improve circulation, and promote tissue healing.
