Physical Modalities • Ultraviolet radiation • İntermittent compression pump • Mechanical spinal traction • Electrical stimulation • Transcutaneous electrical nerve stimulation (TENS) • Interferential stimulation • Direct current • High voltage pulsed galvanic stimulation • Electromyographic biofeedbak

7. Cryotherapy • Historical perspective • Ancient Greeks and Romans • Late 1880’s, cold compresses after surgery • Early 1960’s, cold therapy widely recognized by healthcare as a result of studies by Grant (1964) and Hayden (1964). • Military studies.

8. Effects of cold therapy • Pain relief • A decreased nerve transmission in pain fibres • Cold reduces the activity of free nerve endings • Cold raises the pain threshold • Cold causes a release of endorphins • Cold sensations over-ride the pain sensation - known as the pain gate theory

9. Effects of cold therapy • Reduces Bleeding and Swelling Vasoconstriction followed by dilation is known as the Hunting Response. • Reduces Muscle Spasm This is not fully understood but is thought to be due to ice slowing the conduction velocity of sensory and motor nerves, as well as the activity of muscle spindle cells (responsible for muscle tone), resulting in a decrease in motor activity. • Decreases Metabolic Rate

10. Contraindications Cold hypersensitivity Raynaud’s disease Regenerating peripheral nerves Precautions Over superficial main branches of nerve Peroneal nerve Open wounds Poor sensation Ice

11. Application • 10 minutes is sufficient. • Re-applied regularly, every 2-3 hours. • Following approximately the first 3-5 days of an acute injury

12. Superficial Heat • Infrared • Hot packs • Paraffin wax • Hydrotherapy

13. Red/Infra-Red Phototherapy

14. Conductive HeatHot Packs • Moist heat • Canvas filled wityh silica gel • Immersed in water of about 77 C

15. Paraffin Bath • Tank containing a mixture of paraffin and mineral oil • 52-53 C • Areas that are diffucult to heat • Helps to soften the skin

16. Effects • Local metabolism is increased. • Local persipiration is increased. • Local vasodilation with hyperemia occurs. • Muscle relaxation is promoted. • Sensory nerve endings are sedated. • Capillary pressure and cell permiablity are increased and can promote edema.

17. Indications Infrared • Subacute and chronic traumatic and inflammotory conditions • Seeping wounds that should be dried • Preheating prior to electrical stimulation Hotpack • Subacute and chronic traumatic and inflammotory conditions • Preheating prior to electrical stimulation Paraffin baths • Subacute and chronic traumatic and inflammotory conditions

19. Precautions • Already existing edeme • Patients with sensory loss • Patients who are confused

20. Advantagesİnfrared • The practioner may visually monitor the part being treated with infrared radiation • The infrared lamp does not contact the patient, so tenderness is not aggravatedd. • Clean wounds are safer from the risk of infection

21. Disadvantagesİnfrared • Small, local area with an infrared lamp is diffucult • Positioning diffuculties • Glare from a luminous lamp can be irritating to the patient’s eyes.

22. AdvantagesHP • Risk of burning is minimized • Local areas can be treated effectively

23. DisadvantagesHP • The larger packs can be heavy • Potential enfection if an open wound is present • Skin response diffucult to monitor

24. Paraffin Bath Advantages • Useful for the distal extremities • Softens the skin Disadvantages • Liquid paraffin can be messy • Heat level of paraffin bath to be excessive • Movement must be minimized in a paraffin bath • The tank and paraffin are cumbersome to clean

25. Hydrotherapy

26. Hydrotherapy • Water can be advatageously as a medium for exercise (gravity eliminated environment) • Upward movement is assisted, and downward movement is resisted. • Water will affect movement through it is viscosity. • Viscosity serves to resist movement through the water in all directions • The buoyancy supports the weight of the part, while the viscosity resist the movement

27. HydrotherapyWhirlpool • Water is agitated by an electric turbine • Used for both heating and cooling

28. WhirlpoolPurpose and Effects • The agitation in a whirlpool can serve several purposes: • Phasic stimuli to the skin afferents • The warm water continues to feel warm through-out the treatment

29. WhirlpoolPurpose and Effects • Increase hydrostatic pressure • Increase lymphatic circulation • Provides a means of grading exercise • Decreases the thermal gradients within the water

30. WhirlpoolIndications • Open wounds and burns • Subacute and chronic traumatic and inflammotory conditions • Peripheral vascular disease • Peripheral nerve injures and other conditions that produce muscle weakness

31. Fluidotherapy • Dry whirlpool containing crushed corn husks. • İncreases the circulation by increasing heat in the tissues. • It also increases range of motion.

32. Hubbard Tank(Butterfly -shaped)

33. Hubbard Tank Indications; • Generalized wounds, such as burns • Generalized painful conditions • General sedation or relaxation

34. Low Level Laser Therapy Cold Laser Therapy Primary Effects – Similar to effects of Infrared therapy Secondary Effects – Cell proliferation, protein synthesis, growth factor secretion, neurotransmitter modification Tertiary Effects – System effects; Increase immune response, stimulate bone healing

35. Conditions Commonly Treated withLow Level Laser • Carpal Tunnel Syndrome • Soft Tissue Injuries • Arthritis • Tendonitis • Edema • Nerve Injury • Sprains/Strains • Wounds • Burns

36. Low Level Laser TherapyContraindications Absolute • Pregnancy • Malignancy • Avoid the Thyroid Gland • Avoid the Epiphysis • Photosensitive patients • Immune-suppressed patients Relative • Botox Injections • Anti-Inflammatory meds • Steroid Injection • Some machines use magnetic energy as well no pacemakers

37. Ultrasound • Therapeutic Ultrasound sends high frequency sound waves through tissue and has a thermal effect. • Therapeutic ultrasound frequency used is 0.7 to 3.3.MHz • Maximum energy absorption in soft tissue is 2 to 5 cm. • Intensity decreases as the waves penetrate deeper. • They are absorbed primarily by connective tissue: ligaments, tendons, and fascia (and also by scar tissue)

38. Ultrasound • Typical applications of Ultrasound • Pain control (Munting 1978) • Increase tissue extensibility (Knight 2001) • Accelerate healing wounds (Dyson 1978), bone fractures (Duarte 1983) • Phonophoresis • Application of ultrasound in conjunction with a topical drug preparation for enhanced delivery (ex. hydrocortisone). • Enhanced delivery (McNeill et al Pharm Res 1992)

39. Ultrasound • Two types of benefit: • Thermal effects • Non thermal effects • Indications: • Soft tissue shortening (Joint contractures, scarring) • Subacute and chronic inflammation

40. Electrical Stimulation • Common uses: • Pain control (TENS, interferential) • Iontophoresis (Direct Current) • Muscle stimulation (NMES) • Tissue healing (wound care)

41. PAIN CONTROL AND SELECTIVE STIMULATION • Paintheories • Gate control theory • Endorphinreleasetheory • Postexcitation depression of the sympathetic nervous system

42. Low-frequencycurrentsDiadynamiccurrenttypes • Diadynamic current is particularly suitable for treating pain in small joints (e.g. finger joints and wrist joint). • Segmentalapplication of diadynamic current gives outstanding results in reflex dystrophy (Südeck’s disease) and in superficialhyperalgesia. • A familiar example of the latter is the effect of diadynamic current in the treatment of herpes zoster. • Although there is still little known about the underlying mechanism, the results are astonishing.

43. Medium-frequencycurrents • Although many different types of medium-frequency current may be used, the best known application is interferentialtherapy • The specific application form known as ‘Russian Stimulation’ • Medium-frequency alternating current is suitable fortreatment of deeper-lying tissues (muscles, tendons, bursa or periosteum)

44. TENS (Transcutaneous Electrical Nerve Stimulation) 1-Conventional TENS: -high-frequency, low-intensity TENS -the most generally used of the TENS current types 2-Acupuncture-like TENS: -low-frequency, high-intensity TENS 3-Burst TENS: -modificationof ‘acupuncture-like’ TENS -applied if conventionalTENS proves ineffective,and is particularly suitable for the treatment of deeperlying painful regions (myofascial pain) and cases of chronic pain

45. TENS • Contraindications • Patientswithcardiacpacemakers • Pregnancy • Sitesoverthecarotidsinus, laryngealorpharyngealmuscles, sensitiveeyeareas, ormucosalmembranes • Do not usewhileoperatinghazardousmachinery

46. Iontophoresis • Iontophoresis – use of direct current to enhance transcutaneous administration of ionizable substances • Most commonly used: • Dexamethasone – anti-inflammatory agent • Conditions: • Epicondylitis, tendonitis, etc…

47. Iontophoresis • Iontophoresis may use tap water or anticholinergic drugs to control hyperhidrosis of hands or feet. • Direct current is used, initially 3 times per week, but reducing in frequency until maintenance treatment may only be required every 6 weeks or longer

48. The rehabilitation of those individuals with neurological impairments will require the use of therapeutic procedures and activities to regain their previous level of functional ability.

49. Spinal Orthosis • An external device applied on the body to: • Limit motion • Correct a deformity • Reduce axial loading • Improve function of a particular segment
