I imagine we tend to use that which we know well. My first LD client sought me out for stretching ( my specialization is in Active Isolated Stretching). In addition, Myofascial Release has seemed very powerful in releasing tight tissue especially around hips.
The other modality I tend to use that I am well trained in is Neuromuscular Therapy. Seems to make sense, as my clients have significant neurological issues effecting their mobility.
