  27. 27. Description of orthoses: 1) Calvicular orthoses:  Regional name: shoulder orthosis  Common names: figure of four harness, clavicular brace/ harness
  28. 28. Functions Indications - Restrict motion to promote tissue healing Clavicular fractures - Improve posture - Forward shoulder posture - TOS - Reduced scapular myofascial pain - Cumulative trauma disorder - Increase/maintain PROM - Pectoral contractures
  29. 29.  Placement : - Material goes over clavicles, under arms and crosses over high thoracic spinous processes.  Biomechanical efficacy: - Restrict movement of the clavicle and to some extent inhibit scapular protraction while allowing free movement at the GH joint.  Materials : -Webbing straps - Padding and velcro - Prefabricated orthoses often used.
  30. 30. 2) Arm sling  Regional name: shoulder orthosis  Common names:  figure of eight slings  universal sling  Nothern ring sling  Cuff sling  Hemi sling  Orthopaedic sling  Flail arm sling  Homemade Bandanna-Type sling  Glenohumeral support  Hook hemiharness  Rolyan hemi Arm sling(vertical arm sling)

Functions indications - Immobilize to promote tissue healing - AC joint injury - Scapular, humeral fractures - PO shoulder repair/arthroplasty - PO tendon,artery, or nerve repairs - Rotator cuff injury - Bicipital tendinitis - Prevent overstretching of GH musculature/ligaments - Brachial plexus lesion - Decreased shoulder pain related to arm distraction and shoulder- hand syndrome - Upper motor neuron lesion: hemiparesis with subluxation - Keep hand and forearm elevated to reduce oedema
  32. 32.  Placement :  Most slings support the forearm with the elbow flexed, shoulder internally rotated and arm adducted. -The Rolyan hemi arm sling supports the humerus and allows the elbow and forearm to be free by using a humeral cuff with figure of eight suspension. -The hook hemiharness has two humeral cuffs connected by a posterior yoke and abduct each arm slightly while allowing the elbow and forearm to be free.
  33. 33.  Biomechanical efficacy : - Slings may be static or dynamic. - Dynamic slings use elastic straps and are designed to allow some motion of the forearm while supporting the arm. -The wrist should be supported by the sling to prevent wrist drop if there is distal weakness. - Hand should be higher than the elbow to decrease the oedema. - Care must be taken to mobilize the shoulder SOS possible to prevent adhesive capsulitis.
  34. 34.  Materials : - Cloth -Webbing - Elastic - Metal ring/ fastners -Velcro - Prefabricated slings are often used.
  35. 35.  Contraindications: - Slings have fallen over out of favour with a neurodevelopment treatment approach to UMN lesion because they are thought to encourage flexion synergy, increase flexor tone, and promote contractures. -The Rolyan hemi arm slings or the hook hemiharness may not approximate the GH joint in a large patient.

Recent advances: 1) Ibrahim M et al. did study on Efficacy of a static progressive stretch device as an adjunct to physical therapy in treating adhesive capsulitis of the shoulder: a prospective, randomised study  To compare a static progressive stretch device plus traditional therapy with traditional therapy alone for the treatment of adhesive capsulitis of the shoulder
  70. 70.  CONCLUSION:  Use of a static progressive stretch device in combination with traditional therapy appears to have beneficial long-term effects onshoulder range of motion, pain and functional outcomes in patients with adhesive capsulitis of the shoulder. At 12- month follow-up, the experimental group had continued to improve, while the control group had relapsed.  Physiotherapy. 2013 Oct 3. pii: S0031- 9406(13)00085-0.
  71. 71. 2) Merolla G et al.did study on Efficacy, usability and tolerability of a dynamic elbow orthosis after collateral ligament reconstruction: a prospective randomized study.  To assess the efficacy, usability and tolerability of a dynamic orthosis compared with a standard plaster splint after the reconstruction of elbow medial or lateral collateral ligaments (MCL, LCL).
  72. 72.  CONCLUSIONS:  The dynamic orthosis and the plaster splint both provided effective and safe elbow immobilization after MCL or LCL reconstruction.The orthosis provided greater pain reduction, faster recovery of muscle trophism and grip strength, and was better tolerated.  Musculoskelet Surg. 2013 Oct 25.
  73. 73. 3) Garg R et al.did study on A prospective randomized study comparing a forearm strap brace versus a wrist splint for the treatment of lateral epicondylitis.  To compare the clinical outcomes of a wrist splint with that of a counterforce forearm strap for the management of acute lateral epicondylitis.
  74. 74.  CONCLUSION:  The wrist extension splint allows a greater degree of pain relief than does the forearm strap brace for patients with lateral epicondylitis.  J Shoulder Elbow Surg. 2010 Jun;19(4):508- 12.
  75. 75. 4)WooY et al.did study on Kinematics variations after spring-assisted orthosis training in persons with stroke.  To evaluate the efficacy of training using kinematic parameters after a SaeboFlex orthosis training on chronic stroke patients.  CONCLUSION:  The results of this study indicate that a SaeboFlex training is effective in recovering the movement of the hemiparetic upper extremity of patients after stroke.  Prosthet Orthot Int. 2013 Aug;37(4):311-6.
  76. 76. 5) Forogh B et al.did study on The effects of a new designed forearm orthosis in treatment of lateral epicondylitis.  on the design and testing of a new designed forearm orthosis and explores its efficacious in comparison to the standard counterforce orthosis in patients with lateral epicondylitis.
  77. 77.  CONCLUSIONS:  The new-designed orthosis can significantly relieve pain, improve function, increase pain threshold and grip strength after application. This orthosis seemed to be more effective than counterforce orthosis in relieving pain and increasing the pain threshold probably due to the limitation of forearm supination.  Disabil Rehabil AssistTechnol. 2012 Jul;7(4):336-9.
  78. 78. 6) Chang M et al. did study on Comparison ofTask Performance, Hand Power, and Dexterity with and without a Cock-up Splint.  Men's grip power with the cock-up splint was found to be significantly decreased compared to without the splint. Women's grip and palmar pinch strength with the splint decreased significantly compared to without the splint. In the grooved pegboard test, the dexterity of both men and women with the cock-up splint decreased significantly compared to without the splint
  79. 79.  Conclusion:  To assist patients to make wise decisions regarding the use of splints, occupational therapists must have empirical knowledge of the topic as well as an understanding of the theoretical, technical, and related research evidence.  J PhysTher Sci. 2013 Nov;25(11):1429-31
  80. 80. 7)Whelan DB et al did study on External Rotation Immobilization for Primary Shoulder Dislocation: A Randomized ControlledTrial.  To compare the (1) frequency of recurrent instability and (2) disease-specific quality-of- life scores after treatment of first-time shoulder dislocation using either immobilization in external rotation or immobilization in internal rotation in a group of young patients.
  81. 81.  CONCLUSIONS:  Despite previous published findings, our results show immobilization in external rotation did not confer a significant benefit versus sling immobilization in the prevention of recurrent instability after primary anterior shoulder dislocation.  Clin Orthop Relat Res. 2014 Jan 3.
