Forward Head Posture
Introduction[edit | edit source]
Because of the rising popularity of media devices such as smartphones and computers, frequent users often exhibit incorrect posture.
Forward head posture (FHP) is a poor habitual neck posture
- Defined by hyperextension of the upper cervical vertebrae and forward translation of the cervical vertebrae.[1]
- Thoracic Kyphosis is a complication of the combination of slouched-forward shoulders and rounded upper back.
- Can lead to a painful shortening of the muscles of the back of the neck, as well as compression of the cervical vertebrae—the uppermost portion of the spine that supports the head and protects the spinal cord.
Due to the increased compressive forces through the neck joints and increased muscle tension, pain is the common outcome. Some of the types of problems associated with FHP are:
- Headaches
- Neck discomfort
- Muscle tension in the neck and shoulders
- Discomfort in the mid back
- Chest pain
- Pain, pins & needles and numbness in the arms and hands
Many people develop chronic or recurrent problems because they receive treatment for the pain (e.g. pain killers or anti-inflammatory medication) but never receive treatment for the underlying cause which is their FHP.[2]
Forward Head Posture - affects on Health[edit | edit source]
FHP evaluation is clinically important for diagnosis and rehabilitation treatment.
FHP increases compressive loading on tissues in the cervical spine, particularly the facet joints and ligaments.
Studies have reported that symptoms including neck pain, headache, temporomandibular pain, and musculoskeletal disorders are related to FHP
FHP greatly influences respiratory function by weakening the respiratory muscles[1].
In FHP, the head shifts anteriorly from the line of gravity, the scapulae may rotate medially, a thoracic kyphosis may develop and overall vertebral height may be shortened[3]
In the posterior cervical muscles there is stretching and weakness of Semispinalis cervicis and overaction with ultimate shortening of Semispinalis capitis. The corresponding flexor muscles in front, namely, Longus cervicis and Longus capitis shorten and lengthen respectively.[3]
Causes[edit | edit source]
- Effect of gravity: slouching, poor ergonomic alignment.
- Occupational posture: forward or backward leaning of head for long durations, slouched or relaxed sitting, faulty sitting posture while using computer or screen.
- Result of other faulty posture like pelvic and lumber spine posture.
- Sleeping with head elevated too high.
- Texting posture maintained for long durations.
- Lack of development of back muscle strength.
Source of Symptoms[edit | edit source]
- Anterior location of line of gravity (LOG) causes an increase in flexion (forward head), which requires constant isometric muscle contraction to support head which may result in ischaemia and pain.
- Stretch of suprahyoid muscles pull mandible posteriorly into retrusion which my result in TMJ Anatomy pain and associated fascial tension.
- Narrowing of the intervertebral foramina in lordotic areas of cervical region, which may impinge on the blood vessels and nerve roots, especially if there are degenerative changes.
- Abnormal compression on the posterior zygapophyseal joints and posterior portions of the intervertebral discs.Stress to Anterior longitudinal ligament in upper cervical spine and Posterior longitudinal ligament in lower cervical spine.
Effects[edit | edit source]
- Muscle ischaemia, pain and fatigue
- Decreased range of motion of cervical spine[4]
- Early disc degeneration and osteophyte formation
- Temporomandibular joint pain and inflammation
- Tension Headache
- Increase in dorsal kyphosis and decrease in height
- Decrease in vital capacity and range of motion of shoulder and arm
- Possible protrusion of nucleus pulposus and nerve compression
Potential Muscle Impairments:[edit | edit source]
- Mobility impairment in the muscles of the anterior thorax (intercostal muscles), muscles of the upper extremity [5]originating on the thorax (Pectoralis major and minor, Latissimus dorsi, Serratus anterior), muscles of the cervical spine and head that attached to the scapula and upper thorax (Levator scapulae, Sternocleidomastoid, Scalene, upper Trapezius), and muscles of the suboccipital region (Rectus capitis posterior major and minor, Obliquus capitis inferior and superior).
- Impaired muscle performance due to stretched and weak lower cervical and upper thoracic erector spinae and scapular retractor muscles (Rhomboids, middle Trapezius), anterior throat muscles (suprahyoid and infrahyoid muscles), and capital flexors (Rectus capitis anterior and lateralis, superior oblique Longus colli, Longus capitis).
- With temporomandibular joint symptoms, the muscles of mastication may have increased tension (Pterygoid, Masseter, temporalis muscles).[6]
Postural Analysis[edit | edit source]
Observational postural analysis involves locating the body segments in relation to LOG (representative by plumb line). [7]In an anterior or posterior analysis, the LOG should bisect the body into two symmetrical halves. In a lateral analysis, the LOG should passes anterior to the head, vertebral column, or joints of the lower extremities.[8]
Physiotherapy Management[edit | edit source]
- To Decrease Pain:
- Pain management advice
- Postural Alignment, Balance and Gait:
- Cervical Retraction
- Scapular Retraction
- Balance Training ( If dysfunction presents)
- Range of Motion, Joint Mobility and Flexibility[9]
- Cervical Range of Motion Exercises
- Shoulder Range of Motion Exercises
- Cervical Traction
- Stretching Exercises of tight structures- Trapezius, Scalenes, SCM, Pectoralis Major and Minor.
- To reduce spasm
- Myofacial release
- Ischemic Compression
- Positional release technique (to relieve tension headaches)
- Muscle Strength and Endurance
- Cervical isometric strengthening exercises (initial phase) progressing to isotonic and dynamic strengtening exercises.
- Strengthening exercises for scapular retractors (Rhomboids, middle Trapezius).[10]
- Ergonomic Advice
- Correct the number of pillows used
- Postural corrections.
