Cryotherapy and transcutaneous electric neuromuscular stimulation decrease arthrogenic muscle inhibition of the vastus medialis after knee joint effusion
Journal of Athletic Training, 2002Co-Authors: J T Hopkins, Christopher D Ingersoll, Jeffrey E Edwards, Thomas E KlootwykAbstract:Objective: Arthrogenic muscle inhibition (AMI) is a presynaptic, ongoing reflex inhibition of joint musculature after distension or damage to the joint. The extent to which therapeutic interventions affect AMI is unknown. The purpose of this study was to verify that the vastus medialis (VM) is inhibited using the knee joint effusion model and to investigate the effects of Cryotherapy and transcutaneous electric nerve stimulation (TENS) on AMI using this model. Design and Setting: A3 3 6 analysis of variance was used to compare Hoffmann-reflex data for treatment groups (Cryotherapy, TENS, and control) across time (preinjection, postinjection, and 15, 30, 45, and 60 minutes after injection). Subjects: Thirty neurologically sound volunteers (age 5 21.8 6 2.4 years; height 5 175.6 6 9.6 cm; mass 5 71.5 6 13.3 kg) participated in this study. Measurements: Hoffmann-reflex measurements were collected using a percutaneous stimulus to the femoral nerve and surface electromyography of the VM. Results: Hoffmann-reflex measurements from the Cryotherapy and TENS groups were greater than measurements from the control group at 15 and 30 minutes after injection. Measurements from the Cryotherapy group were greater than for the TENS group, and measurements for the TENS group were greater than those for the control group at 45 minutes. At 60 minutes, the Cryotherapy group measurements were greater than the TENS and control group measures. Measurements at 15, 30, 45, and 60 minutes after injection were reduced compared with the preinjection and postinjection measurements in the control group. Measurements in the Cryotherapy group at 30, 45, and 60 minutes were greater than the preinjection, postinjection, and 15-minute data. No differences between time intervals existed in the TENS group. Conclusions: Artificial knee joint effusion results in VM inhibition. Cryotherapy and TENS both disinhibit the quadriceps after knee joint effusion, and Cryotherapy further facilitates the quadriceps motoneuron pool. Cryotherapy treatment resulted in facilitation of the VM motoneuron pool during the post-treatment phase. The TENS treatment failed to disinhibit the VM motoneuron pool by 30 minutes postinjection.

Cryotherapy following total knee replacement
Cochrane Database of Systematic Reviews, 2012Co-Authors: Sam Adie, Amy Kwan, Justine M Naylor, Ian A Harris, Rajat MittalAbstract:The review shows that in people who have had a total knee replacement: - Cryotherapy may slightly reduce the amount of blood loss and pain - Cryotherapy was generally safe and not associated with any serious adverse events - Cryotherapy may improve the range of movement at the knee in the first one to two weeks after surgery - No studies were found that looked at the effects of Cryotherapy on a person's activities related to knee function (or quality of life, or general activity level) What is total knee replacement and what is cold therapy? Osteoarthritis is a disease of the joints, such as your knee. Osteoarthritis of the knee can make the knee joint painful and restrict function. Knee replacement surgery is a treatment that can help in this condition in the long term, but the effects of surgery during the recovery period (i.e. up to the first six months) are debilitating. Cold therapy (or Cryotherapy) involves the application of very low temperatures to the skin surrounding an injury or surgical site. This can be by means of bags of ice or specialised devices that deliver cooled water to the area. This review shows that there is evidence that Cryotherapy may reduce pain and increase the range of movement in the first few days after a total knee replacement, but the use of Cryotherapy does not reduce the need for blood transfusion. Use of Cryotherapy is safe and did not result in an increase in serious complications. Best estimate of what happens to people who have a total knee replacement and receive Cryotherapy: Blood loss - People who received Cryotherapy had on average 225ml less blood loss than people who did not have Cryotherapy Pain - People who received Cryotherapy reported less pain day 2 postoperatively, on average 1.3 points less on a scale of 0 to 10, but pain levels at day 1 and day 3 showed no difference. Adverse events (unwanted effect including discomfort, local skin reactions, skin infections, cold-related injuries and blood clots) - 34 out of 1000 people who received Cryotherapy experienced one or more unwanted effects - 34 out of 1000 people who did not receive Cryotherapy also experienced one or more unwanted effects Range of motion - People who received Cryotherapy were able to bend their knee 11 degrees more at the time of discharge from hospital Transfusion rate (the requirement for a blood transfusion after the surgery) - This was not reduced in patients who had Cryotherapy Function - There was no evidence found about the effects of Cryotherapy on knee function

Cryotherapy after total knee arthroplasty a systematic review and meta analysis of randomized controlled trials
Journal of Arthroplasty, 2010Co-Authors: Sam Adie, Justine M Naylor, Ian A HarrisAbstract:Cryotherapy has theoretical and practical applications in the reduction of pain, swelling, and blood loss after trauma. We performed a systematic review and meta-analysis of randomized controlled trials on the efficacy of Cryotherapy after total knee arthroplasty (TKA). Eleven studies involving 793 TKAs were included. There was considerable clinical and methodological heterogeneity. Cryotherapy resulted in small benefits in blood loss and discharge knee range of motion. There were no benefits in transfusion and analgesia requirements, pain, swelling, length of stay, and gains in knee range of motion after discharge. Despite some early gains, Cryotherapy after TKA yields no apparent lasting benefits. Patient-centered outcomes remain underinvestigated. The current evidence does not support the routine use of Cryotherapy after TKA.
