Hi Cacrouch1958 - Sorry to hear about the progression of your husbands Parkinson’s disease. It is a disease that seems to affect everyone differently. I was diagnosed in 2017 because of a tremor in one leg. I exercised faithfully until a few months ago when I developed a bad knee. Now I am facing knee replacement surgery. I don’t know how much longer I will not be able to exercise. At least I can still do my voice exercises, thank goodness. You said your husband’s voice was soft. There is a non profit organization that can help him with that, called Parkinson’s Voice Project. Did you know that the muscles you use to speak are the same as the ones you use to swallow so it is important to keep those muscles strong. I went thru their SPEAK OUT! Program and I practice the exercises almost every day and my voice remains strong. If you want to check this program out you can go to ParkinsonVoiceProgress.org and find a provider in your area. And you know the best part? There is no charge. I also have balance issues. I have been to PT for that but now with my bad knee my balance is really off. I have had to resort to using a walker but thankfully I haven’t had but a couple falls. Have you looked for a support group for caregivers? That might be helpful for you. I know how frustrating this disease for me, the patient, can be. I can imagine that you, the caregiver, is just as frustrated.
