GALS screening (Gait, Arms, Legs and Spine) Flashcards
What is the purpose of a GALS exam?
● GALS examination (gait, arms, legs and spine), is often used as a quick screening tool to detect locomotor abnormalities and functional disability in a patient.
What are the three screening questions during a GALS exam?
● Do you have any pain or stiffness in your muscles, joints or back?
● Do you have any difficulty getting yourself dressed without any help?
● Do you have any problem going up and down the stairs?
What is the aim of the first screening question in a GALS exam?
● This question screens for common symptoms present in most forms of joint pathology (e.g. osteoarthritis, rheumatoid arthritis, ankylosing spondylitis).
What is the aim of the second screening question in a GALS exam?
● This question screens for evidence of fine motor impairment and significant restriction joint range of movement.
What is the aim of the third screening question in a GALS exam?
● This question screens for evidence of impaired gross motor function (e.g. muscle wasting, lower motor neuron lesions) and general mobility issues (e.g. restricted range of movement in the joints of the lower limb).
What clinical signs could be suggestive of an underlying pathology during the general inspection portion of a GALS exam?
● Body habitus: obesity is a significant risk factor for joint pathology due to increased mechanical load (e.g. osteoarthritis).
● Scars: may provide clues regarding previous surgery.
● Wasting of muscles: suggestive of disuse atrophy secondary to joint pathology or a lower motor neuron injury.
● Psoriasis: typically presents with scaly salmon coloured plaques on extensor surfaces (associated with psoriatic arthritis).
What objects or equipment could be suggestive of an underlying pathology during the general inspection of a GALS exam?
● Aids and adaptations: examples include support slings, splints, walking aids and wheelchairs.
● Prescriptions: prescribing charts or personal prescriptions can provide useful information about the patient’s recent medications (e.g. analgesia).
What three anatomical positions should you assess the patient in, during a closer inspection of a GALS exam?
Ask the patient to stand in the anatomical position and turn in 90 degree increments
● Anterior position
● Lateral position
● Posterior position
What would you note about posture during the anterior portion of a closer inspection in a GALS exam?
● Posture: note any asymmetry which may indicate joint pathology or scoliosis.
What would you note about scars during the anterior portion of a closer inspection in a GALS exam?
● Scars: note the location of any scars as they may provide clues as to the patient’s previous surgical history and/or indicate previous joint trauma.
What would you note about joint swelling during the anterior portion of a closer inspection in a GALS exam?
● Joint swelling: note any evidence of asymmetry in the size of joints that may suggest unilateral swelling (e.g. effusion, inflammatory arthropathy, septic arthritis).
What would you note about joint erythema during the anterior portion of a closer inspection in a GALS exam?
● Joint erythema: suggestive of active inflammation (e.g. inflammatory arthropathy or septic arthritis).
What would you note about muscle bulk during the anterior portion of a closer inspection in a GALS exam?
● Muscle bulk: note any asymmetry in upper and lower limb muscle bulk (e.g. deltoids, pectorals, biceps brachii, quadriceps femoris). Asymmetry may be caused by disuse atrophy (secondary to joint pathology) or lower motor neuron injury.
What would you note about elbow extension during the anterior portion of a closer inspection in a GALS exam?
● Elbow extension: inspect the patient’s carrying angle which should be between 5-15°.
● An increased carrying angle is known as cubitus valgus. Cubitus valgus is typically associated with previous elbow joint trauma or congenital deformity (e.g. Turner’s syndrome).
● A decreased carrying angle is known as cubitus varus or ‘gunstock deformity’. Cubitus varus typically develops after supracondylar fracture of the humerus.
What would you note about valgus joint deformity during the anterior portion of a closer inspection in a GALS exam?
● Valgus joint deformity: the bone segment distal to the joint is angled laterally. In valgus deformity of the knee, the tibia is turned outward in relation to the femur, resulting in the knees ‘knocking’ together.
What would you note about varus joint deformity during the anterior portion of a closer inspection in a GALS exam?
● Varus joint deformity: the bone segment distal to the joint is angled medially. In varus deformity of the knee, the tibia is turned inward in relation to the femur, resulting in a bowlegged appearance.
What would you note about pelvic tilt during the anterior portion of a closer inspection in a GALS exam?
● Pelvic tilt: lateral pelvic tilt can be caused by scoliosis, leg length discrepancy or hip abductor weakness.
What would you note about fixed flexion deformity of the toes during the anterior portion of a closer inspection in a GALS exam?
● Hammer toe?
● Mallet toe?
What would you note about the big toe during the anterior portion of a closer inspection in a GALS exam?
● Big toe: note any evidence of lateral (hallux valgus) or medial (hallux varus) angulation.
What 11 points should you cover during the anterior portion of a closer inspection in a GALS exam?
● Posture
● Scars
● Joint swelling
● Joint erythema
● Muscle bulk
● Elbow extension
● Valgus joint deformity
● Varus joint deformity
● Pelvic tilt
● Fixed flexion deformity of toes
● Big toe
What 5 points should you cover during the lateral portion of a closer examination in a GALS exam?
● Cervical lordosis
● Thoracic lordosis
● Lumbar lordosis
● Knee joint hyperextension
● Foot arch
What would you note about cervical lordosis during the lateral portion of a closer inspection in a GALS exam?
● Cervical lordosis: hyperlordosis is associated with chronic degenerative joint disease (e.g. osteoarthritis).
What would you note about thoracic lordosis during the lateral portion of a closer inspection in a GALS exam?
● Thoracic kyphosis: the normal amount of thoracic kyphosis is typically between 20-45º. Hyperkyphosis is associated with Scheuermann’s disease (congenital wedging of the vertebrae).
What would you note about lumbar lordosis during the lateral portion of a closer inspection in a GALS exam?
● Lumbar lordosis: loss of normal lumbar lordosis suggests sacroiliac joint disease (e.g. ankylosing spondylitis).
What would you note about knee joint hyperextension during the lateral portion of a closer inspection in a GALS exam?
● Knee joint hyperextension: causes include ligamentous damage and hypermobility syndrome.
What would you note about foot arch during the lateral portion of a closer inspection in a GALS exam?
● Foot arch: inspect for evidence of flat feet (pes planus) or an abnormally raised foot arch (pes cavus).
What 7 points should you cover during the posterior portion of a closer examination during a GALS exam?
● Muscle bulk
● Spinal Alignment
● Iliac crest alignment
● Popliteal swelling
● Achilles’ tendon thickening
● Valgus joint deformity
● Varus joint deformity
What would you note about muscle bulk during the posterior portion of a closer inspection in a GALS exam?
● Muscle bulk: note any asymmetry in upper and lower limb muscle bulk (e.g. deltoid, trapezius, triceps brachii, gluteal muscles, hamstrings, calves).
● Asymmetry may be caused by disuse atrophy (secondary to joint pathology) or lower motor neuron injury.
What would you note about spinal alignment during the posterior portion of a closer inspection in a GALS exam?
● Spinal alignment: inspect for lateral curvature of the spine suggestive of scoliosis.
What would you note about iliac crest alignment during the posterior portion of a closer inspection in a GALS exam?
● Iliac crest alignment: misalignment may indicate a leg length discrepancy or hip abductor weakness.
What would you note about popliteal swelling during the posterior portion of a closer inspection in a GALS exam?
● Popliteal swellings: possible causes include a Baker’s cyst or popliteal aneurysm (typically pulsatile).
What would you note about Achilles’ tendon thickening during the posterior portion of a closer inspection in a GALS exam?
● Achilles’ tendon thickening: associated with Achilles’ tendonitis.
