Had a request for some “tennis elbow” rehab options from @devendrabagwe so here are some interesting ones via @kaitlin.physio
I personally wouldn’t use the first “stretch” the research isn’t strong for stretching tendon’s and in my experience they don’t always respond well to it. The popular “isometric” protocols for tendinopathy may not totally apply to the elbow as that research is in lower limb injuries and they have slightly different properties. However, IMO the main point of that research is load management, with IsoM load being just 1 option. In that case, the same philosophy applies to the elbow-find a load the tendon can handle without getting worse and build from there. In this example they have used eccentric loads, but they might be too much for you, ”make the adjustment” as my old baseball coach used to say.
