Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention in this study will be the provision of a lower limb exercise programme. The 6 exercises are designed to slowly pump the muscles which will help squeeze fluid up the leg. They will be taught by the same physiotherapist to all the participants. The programme starts and finishes with diaphragmatic breathing to stimulate the deep lymphatic system. abdominal muscle contractions are followed by gluteal contactions, quadriceps and hamstring contactions and then gastrocnemius contractions. each exercise is repeated 20 times. theraband resistance is used for each exercise except for the abdominal contractions. the exercises will be taught by a physiotherapist on an individual basis. exercises will be undertaken twice a day for the 3 month trial period. The exercises should take 15 minutes to complete in the patient's own home

Each exercise will be repeated for 20 repetitions at intensity 13 on the Borg Rating of Perceived Exertion (RPE) The Borg Scale is a patient’s subjective measure of physical activity intensity level based on the physical sensations a person experiences during physical activity such as increased heart rate, increased respiration or breathing rate, increased sweating, and muscle fatigue (Borg, 1998). It is agreed that perceived exertion ratings between 12 to 14 on the Borg Scale suggests that physical activity is “somewhat hard” being performed at a moderate level of intensity.
The exercises are graded level 1 (easier) or level 2 (harder)and commence day 1 after surgery with no hip movement for the first 48hours to reduce strain on the suture line in the early post-operative period. Patients can choose which exercise level suits them best to gain level 13 on the Borg Scale. Each participant will be provided with an exercise protocol sheet containing written and pictorial description of all the exercises to ensure they are replicated exactly. Each participant will have their exercise regime checked at every review appointment by the same physiotherapist that prescribed the regime to ensure consistency of technique between the participants. review appointments consist of 40 minute consultations with the physiotherapist at baseline, 1 month, 6 weeks after chemotherapy, 6 weeks after radiotherapy or at 3 months if no adjuvant therapies occur
The intervention group will also receive current standard care. They will be provided with an education leaflet by the physiotherapist detailing strategies to reduce the risk of triggering lymphoedema. Ryan et al (2004) report that patients identified the initial trigger for lower limb lymphoedema and those that exacerbate LLL symptoms. Trigger factor avoidance includes:Skin care – avoiding trauma and injury to reduce infection risk. Avoiding limb constrictions – items that leave deep tissue indentations, Weight maintenance – including the promotion of general exercise to maintain weight and stimulate the lymphatic system, Travel – regular foot and leg exercises for prolonged travel. Compression garments for flights longer than 4 hours, Avoiding extremes of temperature – including saunas and steam rooms, Pre-existing medical condition control – hypertension, cardiac disease, diabetes, thyroid disease, kidney and liver disease. Pre-existing lower limb oedema may require compression therapy especially in those with occupations where prolonged sitting and standing
Written informed consent will be gained from each participant
adherance will be monitored by an exercise partcipation diary completed by the patient

Outcomes
Primary outcome [1] 290135 0
The primary outcome is incidence of lymphoedema.

For the purpose of this study lymphoedema will be defined as 10% limb volume increase, with a concurrent change of 10 points on L-Dex bioimpedence from preoperative baseline in unilateral lymph node dissections.
At present there is no consensus on which measurement or combination of measurement methods reflect the most accurate diagnostic tool.
Circumferential measurements will be undertaken at every consultation using a perometer. Perometry is a sensitive standardised device that uses infrared optoelectric technology to detect and quantify limb volume changes. Perometry is a rapid, simple, non-invasive, reliable measurement tool to determine limb volume in Breast Cancer Related Lymphoedema (Deltombe 2009) The perometer calculates total limb volume and millilitres via a truncated cone formula. Total limb volume includes fat and muscle mass as well as extracellular fluid. A two stage measurement will occur. First from the ankle to the groin, then the foot.
Timepoint [1] 290135 0
Data will be collected preoperatively, 1 month post operatively, 6 weeks after chemotherapy or radiotherapy, or at 3 months if no adjuvant therapies are required.
Pre-operative measurements are vital for this study to account for pre-existing normal interface variance. This may range from 3-10% depending on arm dominance, adiposity and muscularity (Stout). An accurate diagnosis of early post-operative lymphoedema cannot be made unless premorbid limb volume disparity is quantified and regular follow up conducted to monitor for limb volume change. (Stout)
Data collection will be scheduled alongside a patient’s normal postoperative / post adjuvant therapy review appointments with the gynaeoncology multidisciplinary team. Any participant complaining of subjective signs and symptoms of lymphoedema in the 3 months study will be given an extra measurement for diagnostic purposes only.
Primary outcome [2] 290136 0
the primary outcome is Incidence of lymphoedema

For the purpose of this study lymphoedema will be defined as 10% limb volume increase, with a concurrent change of 10 points on L-Dex bioimpedence from preoperative baseline in unilateral lymph node dissections.
At present there is no consensus on which measurement or combination of measurement methods reflect the most accurate diagnostic tool.
The U400 bioimpedence spectroscopy will calculate the L-Dex directly. Bioimpedence spectroscopy assesses extracellular fluid and has been proven to identify subclinical lymphoedema i.e. increases in extracellular fluid before clinical objective signs of lymphoedema present. This is a measure of extracellular fluid only, removing any limb volume changes caused by weight or muscle mass gain or loss. Bioimpedence will be used alongside perometry in unilateral cases to ensure that early subclinical lymphoedema is not missed as perometry may be insensitive to early changes in extracellular fluid.
At each follow up the evolution of the difference in limb volumes between affected and unaffected limbs will be compared to correct for weight gain. For this reason a participant’s body weight will also be measured at each visit using scales to control for weight change. The same physiotherapist will undertake all measurements at the same time of day for reliability.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This pilot study is a prospective 2 group parallel RCT. 30 subjects will be randomised into an experimental group who will receive instruction in an exercise programme and taught lymphoedema trigger factor avoidance strategies or a control group who will be taught trigger avoidance strategies alone. The assistant researcher will attend the pre assessment clinic for gynaeoncology at Monash Health. Patients due to undergo inguinal or pelvic lymph node dissection will be highlighted from the clinic list. These patients are then identified as potential participants. Each participant will be verbally informed about the study and the committment required for participation to ensure adequate understanding of both the proposed research and the implications of participation in it. They will then be given written information to reiterate the verbal communication. They will be asked whether they consent to participating or not
Those that give consent will be required to complete and sign a consent form
For those undecided a follow up telephone call will be made 48 hours later. if they consent to participating a consent form will be mailed for completion
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be conducted using a permuted blocks approach, and stratified by whether participants had unilateral or bilateral surgery. Personnel responsible for recruitment and baseline assessment will be unaware of the future sequence within the randomisation, the randomisation sequence will be generated by an investigator unaware of participant assessment findings
