Does the Wartenberg pendulum test differentiate quantitatively between spasticity and rigidity? A study in elderly stroke and Parkinsonian patients.

The results of applying the Wartenberg pendulum test to the assessment of muscle tone in populations of stroke and Parkinsonian patients are described. The test was able to distinguish between increased muscle tone of the spastic or rigid type. The Parkinsonian patients showed a marked reduction of the maximum velocity of the leg swing, with the relaxation index tending to a value of about one. In contrast the affected limb of stroke patients showed a lesser reduction of the velocity of the swing, the relaxation index tending to a value of less than one.

Surgical approach to the diagnosis of tumours occurring in the superior mediastinum.

The nature of tumours lying in the superior mediastinum can frequently be decided by the radiologist using a range of techniques varying in sophistication from the plain chest radiograph to transvenous biopsy. Histolocical proof of such lesions usually requires surgical exploration and of the methods available it is believed that mediastinotomy is the safest and most rewarding in terms of positive results. Radical excision of tumours and management of tracheal lesions require the greater surgical access afforded by thoracotomy, median sternotomy and the sternal resection of Grillo.
