| Summary: | In this thesis, a tool with which to describe turning, the Standing Start 180° Turn Test (SS-180) was developed and used to describe how people with and without PD turned to walk from a standing start. Seventy descriptors of turning were identified from five sources (including the literature). These were reduced to a shortlist of 20 considered important and measurable from video, from which the SS-180 was designed. Participants turned in each direction during the SS-180 and Turning Steps, Time, Type and Quality were rated. The video-based SS-180 was validated against a laboratory-based 'gold standard' and test-retest stability, intra- and inter-rater reliability was established. Thirty-three healthy adults (median age 40 years) took part in the first (laboratory-based) study. Turning took a median 2.5 Steps in a median 1.5s. Toward (36%) and Pivotal (33%) Turn Types were common; Quality was maximal (five/five) for all but one turn. Seven people with PD (median age 77, median PD duration eight years) took part in a preliminary (laboratory-based) study. Turning took a median six Steps, 3.9s. Incremental (71%) Turn Types were common; Quality was sub-maximal in most cases. Twenty-three people with PD (median age 68, median PD duration four years) and ten age-matched controls (median age 70) took part in the main (home-based) study. Participants with PD turned in a median 3.8 Steps, 2s; Incremental (64%) Turn Types were common. Controls turned in fewer Steps and faster (P |
