It is often noted that during an episode of freezing, the more the patient worries about the functional end-goal of walking (freeing the elevator entry for other people to come out, moving out of a crowded store through  11 a narrow exit, entering the doctor’s office), the more difficult the task becomes, particularly as others look on The emotional stress associated with the social function of walking... improvements occur regardless of whether the patient is on or off medication at the time of training (McIntosh et al., 1997) The effects of auditory cueing by metronome on gait may depend on the frequency used for the metronome beat, which may have to be 5 slightly faster than the baseline walking cadence to be efficacious PD patients using such rhythmic cues set at rates of 107.5 and 115% of their baseline walking... recommendations consisting of strict programs of daily home exercises in the mild to moderate stages of the disease and the teaching – to the patient and then to the care-giver – of compensation strategies in the late stages Acknowledgments We are grateful to Jerri Chen and Jonathan Alis for their excellent work in illustrating some of the exercises recommended in this chapter We also thank Sheree Loftus Fader,... the therapeutic focus may shift from the teaching of exercises to the teaching of compensation strategies allowing preservation of as much functional independence as possible These strategies include adaptation of the home environment, both to lessen the effects of motor impairment and to optimize safety 30.1 Physical exercises in mild to moderate stages of Parkinson’s disease Most studies investigating... that rural living, well-water consumption and exposure to pesticides increase the risk of developing PD, whereas there is a decreased risk of PD associated with smoking and coffee consumption (Koller et al., 1990) None of these factors, however, explain the large majority of cases who appear to have a sporadic form of the disease Indeed, twin studies suggest that genetic factors probably play a dominant... Postmortem studies in the substantia nigra of PD patients demonstrate increased levels of iron (which promotes oxidative stress) and decreased levels of glutathione (the major brain antioxidant) (Jenner and Olanow, 1998) Further, there is evidence of oxidative damage to carbohydrates, lipids, proteins and DNA in the SNpc of PD patients Additionally, the oxidative metabolism of levodopa and/or dopamine can generate .
