Abstract: | In recent years a variety of behavioral techniques have been used in the treatment of spasmodic torticollis including negative practice (Agras and Marshall, 1965). faradic aversion (Brierly, 1967). instructions and negative feedback (Bernhardt et al., 1972). and systematic desensitization (Meares. 1973). However, in most of the aforementioned reports the controlling effects of the particular technique over dependent measures (voluntary and/or involuntary evocations of the tic) have not been demonstrated experimentally (see Hersen and Eisler, 1973 for review). In the present single case experimental analysis (Barlow and Hersen. 1973; Hersen and Barlow, 1974). the effects of massed practice (see Yates. 1958) and meprobamate on a subject exhibiting spasmodic torticollis were systematically examined. Following Bernhardt. Hersen and Barlow (1972). treatment efficacy was evaluated by monitoring rate of involuntary torticollis movements per 10-min videotaped recording sessions. |
