Forward displacement of one vertebra on its lower neighbour. Most commonly seen at L5/S1. The degree of spondylolisthesis is determined by the distance the slipped vertebra travels on its lower counterpart - Grades 1 - 4. Most commonly described as: congenital, spondylolytic, traumatic, degenerative or pathological. Can often be found incidentally.
Caused by a defect in the pars interarticularis, a narrow strip of bone lying between the lamina and the inferior articular process below, and the pedicle and the superior articular process above. May be congenital, of traumatic origin or of overuse, resulting in a stress fracture. In oblique x-ray views, which have the appearance of a "Scotty Dog" , a spondylolysis through the pars interarticularisshowing will show up a "collar" around the dog's neck. This may be incidentally found.
Degenrative processes which affect the intervertebral disc. Most commonly, the major change is that of osteophytosis, the formation of bony spurs along the junction of the vertebral bodies and the corresponding intervertebral discs.
Technique of ankle strapping using rigid tape (usually zinc oxide). The tape is placed on the ankle, medial to lateral adhering to the undersurface of the heel, mimicking a "stirrup".
Straight leg raise (SLR)
Technique for measuring sciatic nerve mobility and/or hamstring length. Non-specific test, but still used as a guide during musculoskeletal examination.
Non-specific term given to excessive or abnormal loading of tissues. Muscle strain is an overload, to a degree of failure, of muscle tissue. Can be used interchangeably to describe the sensation felt during exercise or activity.
Fracture caused by non-traumatic, cumulative overload on bone. Can be caused by a number of factors including overtraining, incorrect biomechanics, fatigue, hormonal imbalance, poor nutrition and osteoporosis. Best investigated by Technetium bone scan, as this will show up a stress fracture within 48 hours. Plain x-rays will show up a stress fracture, but ususally only after 10 days. Examination will almost always show up a specific point of maximal tenderness over bone, with possibly some global tenderness, in the region, due to the reactive periostitis and soft tissue irritation.
A region of the shoulder that is bordered by the so-called subacromial joint - a joint made up by the humerus and a superior arch, consisting of the acromion process and the coracoid process of the scapula, joined by the coraco-acromial ligament. This arch is lined by the synovium of the subacromial bursa. In the subacromial space runs the rotator cuff.
A condition characterised by severe pain, swelling an disability. Commonly seen in the foot, but may occur in other joints of the lower limb. Aetiology unknown, but it probably represents a neurovascular disorder leading to an intense hyperaemia and osteoporosis of bone. Has been considered part of the Reflex Sympathetic Dystrophy "family" of conditions.
If the subacromial space is pathologically, or congenitally, narrowed, an impingement of the supraspinatus tendon may occur. Characterised by pain, into abduction, and positive "impingement" tests. Patients will often attempt to deviate away from the impingement, attempting to gain the necessary movement by using "trick" movements.
Overuse or trauma to the supraspinatus tendon. Commonly seen when there is a degree of supraspinatus tendon degeneration or degradation. Active contraction of the supraspinatus will cause pain and there is usually an arc of pain on abduction - described as 60 - 120° in most textbooks.
Symptoms associated with, usually, a hypomobility lesion at T4 (+/- 1 - 2 levels). Complaints of arm pain or vague discomfort in the arm, accompanied by parasthesia, do not follow any dermatomal patterns. There may also be associated hand symptoms, which are considered to be an integral part of T4 syndrome. The mechanism of pain production in T4 syndrome is unknown, but it is postulated that autonomic nerve control may be compromised.
Technetium bone scan
A sensitive radiological investigation, utilising a radio-isotope, used in the detection of stress fractures, as well as other bony pathology.
Temporomandibular joint (TMJ)
Joint between the condyle of the mandible and the mandibular fossa and the articular eminence of the temporal bone. There are several distinctive features of this joint, namely: a separate joint is formed on each side of the face, but function together as one unit; it is lined by fibrous cartilage and not hyaline cartilage; it contains an intra-articular meniscus that divides the joint into two separate synovial cavities.
Inflammatory condition of the tendon. Has been used interchangeably with inflammatory conditions of the tendon sheath or paratenon. Pain is reproduced with resisted movements and tendon stretching, with active range of motion often normal, but with pain experienced at the end of range.
May follow trauma, overuse or inflammatory conditions. There is complaint of pain, swelling and/or restricted movements. The swelling has a characteristically linear appearance, along the tendons.
Detects a fixed hip deformity, in patients who have developed a compensatory lumbar lordosis that then masks the hip flexion.
Thoracic outlet syndrome
Compression of the neurovascular bundle, comprising the brachial plexus and the subclavian artery, will produce a mix of symptoms, ranging from pain in the shoulder and arm, to neurological and vascular symptoms. The compression usually occurs in the thoracic outlet of the neck. Pain and parasthesiae are most commonly experienced on the ulnar side of the arm. Three syndromes have been identified: the costoclavicular syndrome (most common) which is characterised by a decreased space between the clavicle and the first rib; the cervical rib syndrome which is characterised by the presence of either a rib emanating from the C7 or a fibrous band passing from C7 to the first rib. Cervical ribs occur in approximately 1% of the population; and the anterior scalene syndrome (very rare) whereby the neurovascular bundle is compressed between the scalenus anterior and the scalenus medius muscles. Some tests are available to attempt to diagnose this condition, but they often provide false positives during the procedure.
Comprising 12 vertebrae, sitting between the cervical and lumbar spines. Provide attachments for the ribs.
Therapy to provide a distraction force, whether it be to the spine or to the peripheral joints. Indicated for nerve root lesions or conditions that have, as part of their pathological process, compressive forces e.g. osteoarthritis.
Transcutaneous Electrical Nerve Stimulation (TENS)
Modality for providing pain relief, in a portable form.
Deep massage technique, predominantly used for tendon and ligament conditions. Technique is performed across the line of the tissue fibres.
Intrinsic disorder of the abductors of the hip, due to either a weakness or an inhibition to function. As a result, the hip abductors are unable to stabilise the hip, as body weight is transferred to the affected side, resulting in a pelvic drop or tilt towards the opposite side.
Tests the ability of the hip abductor mechanism to stabilise the hip, while the patient stands on one leg. The Trendelenburg test is positive when the patient stands on one leg and the opposite side of the pelvis then drops.
Occurs when there is nodule formation within the flexor tendon of the hand. It usually occurs secondary to tenosynovitis (usually due to overuse) or to rheumatoid arthritis. Most commonly, the nodule is trapped under the metacarpophalangeal ligament, as the tendon flexes. Corticosteroid injection usually relieves the symptoms, but sometimes surgery is indicated.
Often associated with gluteus medius tendinitis, this condition is characterised by an inflammation of the bursae overlying the greater trochanter of the femur, most commonly the large multilocular bursa that lies between the gluteus medius and the tensor fascia latae. It is an overuse injury, predominantly seen in runners. Pain is often reproduced on stretch (hip flexion to 90° with full lateral rotation of hip) or contraction of the gluteus medius (resisted abduction of the hip).

Upper limb tension test (ULTT)
Considered an analogue to the straight leg raise test for the lower limb, it assesses pain responses consequent upon passive movements of the upper limb and neck. The traditional ULTT produces strain on the brachial plexus by a combination of movements involving shoulder girdle depression, shoulder abduction, external rotation of the shoulder, elbow extension, forearm supination and wrist/finger extension. Cervical spine ipsilateral and contralateral lateral flexion are also important to differentiate. This traditional test provides bias to the median nerve. Variations have developed , over the years, to address the other nerves of the upper limb, including the radial nerve and ulnar nerve.
Refers to a lateral inclination of a distal bone, of a joint, from the midline.
Refers to medial inclination of a distal bone, of a joint, from the midline.
This forms part of the quadriceps mechanism. The fibres lie in a plane parallel with the anterior aspect of the shaft of the femur.
Forms the middle layer of the quadriceps group, providing stability rather than fast movement.
Located on the anteromedial aspect of the thigh. Recently been investigated for its role in patellar stability, with particular reference to patellofemoral dysfunction.
Vertebral artery testing
Performed to assess the relationship between cervical spine movement and symptoms which may be vertebrobasilar in origin. If the subjective examination suggests that blood flow may be affected (with complaints of dizziness, tinnitus, diplopia, dysphagia, dysarthria or "drop attacks"), then vertebral artery testing MUST be performed. The tests that are advocated are:
· sustained rotation, left and right;
· sustained extension;
· sustained rotation and extension, left and right; and
· any position that is described, by the patient, that elicits dizziness.
Elicited when the extended arm is pushed against resistance. The scapula "wings" out when there is a weakening of the serratus anterior, usually caused by a long thoracic nerve lesion.
An apparatus used for the re-education of proprioception and balance.
Plain radiographs, usually taken when there is a history of trauma, to exclude fractures. Also used to confirm degenerative disease processes. Non-specific investigation for soft tissue injuries.
A test for biceps tendon subluxation, at the shoulder. It is performed with the Therapist resisting shoulder flexion, elbow flexion and forearm supination. Palpating the biceps tendon is integral, to feel for the subluxation. May also be used to detect biceps tendinitis, but it will be pain in the bicipital groove noted and not instability of the tendon.
Formed between the superior articular process, of the lower vetebra, and the inferior articular process, of the upper vertebra. They are described as plain synovial joints.
