These early forays into remedial exercise coincided with physiotherapy becoming established as a professional adjunct to other forms of medical treatment. Remedial exercise, based on Swedish gymnastics and massage, was widely practised in the rehabilitation of injured troops. Even exercise machines, which we now tend to think of as the unique invention of Joseph Pilates, were in use by other remedial practitioners. For example, the London Command Depot, Shoreham, Sussex where around 650 men a day were treated, employed a beam, pulley and sling apparatus, designed by Mrs Guthrie Smith, to give both active and passive exercise. The suspensory apparatus encouraged the use of minimal effort in the execution of movement exercises. Practitioners at Shoreham also recognised the relationship between mental attitude and physical exercise, employing psychological approaches to encourage the men to develop a positive attitude toward healing.
