my answer fully endorses fyzzio's comments. And if you have a number of patients doing exercises at home is it really realistic to buy in masses of equipment? You can't supply everyone all the time. The only thing I give out free for ever is theraband which costs a lot! Swiss balls have to be bought by patients after they become interested in using them. Using a bit of imagination and correct instruction and motivation anything is possible. And if compliance for some reason is still not enough then the best programm will fail.
