As regards wrist kinematics, you might consider some of the Virtual
Reality measurement systems mentioned in the FAQ for sci.v-r; some
of these, and other systems are:
 
(1) the electromagnetic systems from Polhemus Inc. (3Space Isotrak, FasTrak)
    and from Ascension Inc. (The Bird), both of Colchester/Burlington in
    Vermont, USA, with The Bird allegedly superior in terms of
    insensitivity to neighbouring metallic objects;
    Polhemus:  Tel +1(802)655-3139, FAX +1(802)655-1439
    Ascension: Tel +1(802)655-7879, FAX +1(802)655-5904
    Noncontact (but cabled) measurement of 6 DOFs, single or multiple
    sources/sensors
    (prices from approx. US $ 2000, OEM; from approx. US $ 3000, single units)
 
(2) the electrogoniometric system from Shooting Star Technology (ADL-1)
    in Burnaby, BC, Canada, Tel. +1(604)298-8574, FAX +1(604)298-8580
    Contact measurment of 6 DOFs.
    (appr. 1500 $ - US or Canadian ?)
 
Also, there are various (expensive) video and ultrasonic systems
