Construct validity of the Chinese version of the disability of the arm, shoulder and hand questionnaire (DASH-HKPWH)

The study evaluated the construct validity of the Chinese Hong Kong version of the disabilities of the arm, shoulder and hand questionnaire (DASH-HKPWH). Three hundred and thirty four patients with a broad range of upper extremity disorders were recruited into the study. Each completed DASH-HKPWH and SF-36 forms and their pain intensity (numeric pain rating scale) and grip strength were also measured. The mean DASH-HKPWH score was 40 (SD = 20). Principal component factor analysis identified a single factor, which accounted for 47% of the total variance. Pearson correlation was applied to assess convergent and divergent validity of the DASH-HKPWH by comparison with the above-mentioned subjective and objective measurements. Our findings were comparable to the DASH of other languages

Artificial hand - from a robotic perspective

The human hand provides proof that the anthropomorphic configuration, properly controlled, is successful and gives a target to aim at for artificial hand/robot hand researchers. In this paper we discuss the human hand physiology and grasp capabilities. We then provide design on a double thumb, two finger robotic hand. Architecture of the hand, fingers and their dynamic modelling is discussed. Finally, results are reported on the performance of a finger in the hand.

2nd Hand Cinema

A celebration of the offal of cinema, old films, old soundtracks, drawing directly on the film, using stamps and food-dyes to create discarded imagery. To chew film up and spit it out as painting direct.
