Solanki Sensory Assessment Superficial sensory assessment on dermatome distribution of wrist and hand and recording it as: (0: Absent, 1: Impaired with % Loss or 2: Intact) Deep sensory assessment: Deep Pressure Weber’s (Moberg’s) Two‐Point Discrimination Test Punita V. Solanki ( Normal: <6mm, Fair: 6‐10 mm, Poor: 11‐15 mm, Protective: 1 point perceived, Anesthetic: 0 points perceived) (Functional needs e.g. winding a watch: 6 mm, handling precision tools: 12 mm and gross tools: >15 mm) Dellon’s Moving Two‐Point Discrimination Test: Functional implications.

Accuracy of strength grading depends upon: stable position of the patient the fixation of the part proximal to the tested part precision of test position the direction and amount or pressure/resistance Punita V. Solanki Methods of manual muscle testing e.g. Break Vs. Make test, Scoring: MRC, Daniels & Worthingham, Kendall & McCreary; Subjective Vs. Objective methods of evaluation. Consistency in methods of documentations of muscle testing. Bilateral assessments for comparison Purpose of Evaluation: Diagnosis, treatment outcome or prognostic value of treatment used. Manual Muscle Testing Some Facts about Wrist and Hand Muscle Strength “Weakness” is used as an overall term covering a range of strength from zero (0) to fair (3) in non‐weight bearing upper limb muscles. The strength of the finger flexors is over twice that of the extensors. FDS is the strongest muscle of the extrinsics of hand. 2nd & 4th digital flexor tendon sheath annular pulley system plays an Punita V. Solanki important role in maintaining a constant moment arm for finger flexors. The excursion of the flexors > extensors, extrinsics > intrinsics. The position of the thumb & the relationship between hand & forearm are the most important differences between power grip Vs precision handling. Dominant hand grip and pinch strength is more than the non‐dominant hand by 10%. Palpation and Manual Muscle Testing Documentation Template Joint Punita V.

Economic Impact of Hand and Wrist Injuries: Health‐care Costs and Productivity Costs in a Population ‐Based Study. J Bone Joint Surg Am. 2012 May 2;94(9):e56. Doi: 10.2106/JBJS.K.00561. Punita V. Solanki Conclusion: Hand and wrist injuries not only constitute a substantial part of all treated injuries but also represent a considerable economic burden, with both high health‐care and productivity costs. Hand and wrist injuries should be a priority area for research in trauma care, and further research could help to reduce the cost of these injuries, both to the health‐care system and to society. 14 02/01/2016 Take Home Message “The hands are the instruments of man's intelligence.” ~ Association Montessori Internationale Assess, Assess and Assess in the Beginning, During and After the Treatment. It is the first most important step towards successful outcome. Diagnosis is often based on clinical assessment, Investigations Punita V. Solanki are to confirm the findings, for objective documentation for progress notes, for insurance purpose, for legal implications. Be observant, update your knowledge and refine your clinical skills with perfect practice. (“Perfect practice makes man perfect.”) Quiz Time Punita V. Solanki Which test is this? This is for dorsal interossei (abductors) of the middle finger. With the hand kept flat on a table palmer surface down, the patient is asked to move his middle finger sideways.
