## 4 Discussion  
It has been shown that despite the presence of PD, participating in meaningful occupations assists them in maintaining their overall wellbeing [16]. Heightening the meaning of interventions for PD patients can be important for improving their occupational engagement, especially after study cessation. When patients with PD engage in exercises that hold more meaning to them than traditional aerobic exercises or when the activities are more occupationally based in nature, it leads to higher levels of satisfaction with treatment and better treatment outcomes for PD patients in these studies [45]. Engaging in an activity or an occupation that an individual with PD wants or chooses to do can facilitate their \"mental and emotional state\" in a positive way [16]. The goal of engaging in meaningful occupations is to create a state of full concentration in which patients and clients are fully immersed in their occupations of choice. Being able to provide a wide variety of treatment options to patients, rather than traditionally used aerobic exercises for PD patients, will hopefully lead the client to believe that they have a higher sense of control in their treatment plan. The goal is that this, in turn, will help PD patients find or make meaning in their chosen rehabilitation occupation and encourage them to continue their occupation after study cessation to create a lifelong meaningful occupation [46]. The hope is that this will increase the ability for the client to have a deeper investment and concentration in the task they are performing and that this investment will carry on post-study treatment, turning the study task into a meaningful occupation rather than a short-term activity. \begin{table}

Table 1: Comparison of activities. Essentially, meaning is what separates occupations from activities. Meaning can provide clients with purpose and contentment (Table 2). Offering patients meaningful options that fit their activity level and lifestyle preferences can motivate PD patients to continue with their treatment and change their lifestyle habits, thus leading to the hope of continuing to slow the progression of their PD motor-related symptoms [47]. The meaning of the occupation can exist where the competency of the activity does not; the meaning of the activity can even assume the role of competency, causing the competency of the activity to be irrelevant to one's chosen occupation [16].
