Please contact Lyn who will organise an initial assessment with you or the research assistant 1 PROTOCOL FOR MEASUREMENT OF PERFORMANCE EQUIPMENT Bathroom scales Tape measure (check on wall – for height) 54 cm chair Dynamometer, standard padding, board and padded donut Stopwatch Plinth in gym Block to raise floor height Tape measure and ruler for chair height 45 cm chair with arms 6 metre walking track 15 cm step adjacent to a hand rail Pens for heels and tape 1. Maximal Voluntary Contraction (MVC) • Use Safe Operating Procedure for use of the dynamometer • Start with patient sitting in a 54 cm chair with hips and knees at 90 degrees flexion • Use the attachment with the groove for the tibial measurements and padding on the attachment. • This should be placed in line with the subject’s ankle joint. • Measurer prepares themselves to match the force of the subject but without pushing against them (“Make Test”) • Measurer to stabilise themselves by holding the chair • Subject is instructed to push as hard as they can. Instructions may include repetitions of “Push”or “keep going”. • Allow the subject one practice contraction • Record the best of three attempts (1) Quadriceps - align the interface in the middle of the anterior shank close to the ankle. (2) Hamstrings - align the interface with the middle of the posterior shank close to the ankle. 2. Lowest Possible Chair Height • Have the patient sitting on the raised adjustable plinth with the feet hip width apart, thighs parallel, toes under knees and arms folded. • Place a floor marker at the position of the feet • Explain the procedure using the following words: “I want to find out the lowest height you can stand-up from without using your hands. The bed you are sitting on can go up and down. Fold your arms across your chest. When you stand-up keep your arms against your chest. Make sure that the backs of your legs do not push against the bed as you stand. Have three practice runs to make sure that you understand.” • After the practice runs give the person positive feed back about their attempt if it is correct and advice about what to change if their attempt was incorrect. Manual guidance may be used. Only provide the subject with sufficient information to 2 • • • • • • • • enable them to be successful. If the subject is unsuccessful after three attempts then cease the testing procedure. Use these trial attempts to gauge how easy/hard the initial height is. If the subject’s observed exertion level is: very hard - lower the bed by 1 cm, hard lower the bed by 5 cm, easy - lower the bed by 10 cm. Lower the bed gradually until they are unable to stand-up. Once this height is reached then increase the height incrementally until they are successful again without compensating. A successful attempt is one where the patient’s arms remain folded, against their chest and their legs do not push against the bed. Allow 1 to 2 minutes rest between attempts at the lowest height if the subject is having physical difficulty such as increased shortness of breath. If the subject is able to stand-up from the lowest bed height then place a 10 or 15 cm block underneath their feet and raise the bed height by an appropriate amount until the height at which they can no longer stand-up is reached. Measure the height in millimeters Allow uneven weight-bearing but no other compensations 3. MVC (Cont.) The subject needs to move to a plinth and get into supine. (3) Hip extensors - place a board under the subject’s leg so the dynamometer is on a hard surface. Place the dynamometer under the subject’s heel with the piece of padding in between. Instruct the subject to keep their knee straight and press down through their heel. The dynamometer may need to be stabilised to prevent it from slipping on the board. Do not allow external rotation of the hip. (4) Hip abductors - The subject’s heel should be placed on the donut ring to allow it to slide along the board. Place the dynamometer on the lateral side of the ankle adjacent to the line of the joint. Instruct the subject to keep their knee straight and push their leg against the device near the ankle. Stabilise the non-tested leg while testing. Check the leg does not externally rotate or flex at the hip. 4. Physical Performance & Mobility Examination (PPME) FUNCTIONAL STATUS SCREENING • Ask the patient if they feel they have any restrictions they might have which might prevent them from doing any of the tasks involved and record these • Participants should be encouraged to perform each test if possible but also instructed not to perform if they feel they will be unsafe. INSTRUCTIONS TO PARTICIPANTS • Examiner needs to consider the patients understanding and provide appropriate level of instruction. • Describe each test according to guidelines and do not provide additional encouragement beyond these instructions. • Demonstrate the test for the participant where indicated in these instructions. RESTS Participants are able to rest briefly in between tasks for the sake of enabling completion. 3 SCORING Score accordingly if the person stops, refuses or unable to complete (fail = 0) High pass = 2 Low pass = 1 Fail = 0 TASKS BED MOBILITY (SUPINE TO SITTING) • Bed at lowest height (ie, approximately 45 cm) • Start with participant supine • Start timing when you say begin and stop timing when the feet are over the side of the bed, participant sits upright and movement has stopped. • Initial Instruction: “When I say begin, I want you to put your feet over the side of the bed and then sit up on the side of the bed. You may push off from the bed.” • Verbal cues (to be provided after 20 sec if unable to perform - step by step after each part of movement) Roll to your side Put your legs over the side of the bed Push yourself up with your arms Scoring: 2 High Pass = Completes without assistance < 10 sec 1 Low Pass = completes without assistance more than or equal to 10 sec, in 2 tries or needs verbal assistance 0 Fail = unable to complete without physical assistance STANDING UP FROM BED AND MOVE TO CHAIR (TRANSFER TO CHAIR) • 45 cm chair with arms placed next to the bed. Bed should be at its lowest possible height (47 cm). • Initial instruction: “Stand up from the bed, move to the chair and sit down. When the backs of your legs are touching the chair you may sit down” • Examiner may provide assistance as necessary • Ensure participants legs are free of the bed Scoring: 2 High Pass = completes without assistance 1 Low Pass = completes with assistance 0 Fail = unable to complete STANDING UP FROM A 45 CM CHAIR x 5 Instructions: • “Try and stand up without using your hands to push up on the arms of the chair” • “Now when I say begin, stand up five times as quickly as you can without stopping in between.” • “I’ll be timing you so do this as rapidly as you can comfortably do it.” Record time taken to complete 5 stands 4 Scoring: 2 High Pass = completes 5 stands without using arms 1 Low pass = completes 5 stands using arms or moves all way to edge of chair 0 Fail = unable to complete even using arms STANDING BALANCE • Tests are performed with eyes opened • Positions must be maintained for 10 seconds; without the use of aids, initially may be supported by examiner • Positions: • Position 1: Standing with feet apart (shoulder width apart) • Position 2: Feet side by side within 2.5 cm apart • Position 3: Semi-tandem stand (whichever foot most comfortable in front). Feet within 2.5 cm apart. • Position 4: Tandem stand (whichever foot most comfortable in front). Feet within 2.5 cm apart. • Progress from position 1 to 4 based on performance of easier positions, with subjects preferred foot in front • Start timing from release of participant’s arm • Stop timer if foot moves or person requires support and record time taken if less than 10 sec • For positions 1 & 2 • Instructions: “You may use your legs for balance but do not use your arms. Try to hold this position until I say stop. It helps to keep your balance by looking up and straight ahead.” • For position 3 • Instructions: “Try to stand with the side of the heel of one foot touching the big toe of the other foot – like this” • For position 4 • Instructions: “Try to stand with the heel of one foot in front and touching the toes for the other foot” Scoring: 2 High Pass = Able to maintain all manoeuvres for 10 sec 1 Low Pass = able to maintain feet apart, feet together and semi-tandem for 10 sec, able to maintain tandem for less than 10 sec 0 Fail = unable to maintain feet together, feet apart or semi-tandem for 10 sec STEP UPS • Move over to stairs and position 15 cm platform adjacent to rail. • Determine ability to step up once and down once without using handrail or use handrail but without support from another person. A PUF or stick may be used for additional hand support where required. • Instructions: • “Step forward up onto the step without using the rail”(If unable after 3 tries patient may use the rail.) • “Step forwards and down without using the handrail”(If unable or looking unsafe patient may use the handrail.) 5 Scoring: 2 High Pass = Completes without using handrail 1 Low Pass = Completes using handrail or requiring physical assistance 0 Fail = Unable to complete even with physical assistance AMBULATION 6 M • In order to collect step length data pens should be taped to subject’s heels with patient seated 1 metre prior to the start of a 6 m walkway. Attach pens to patient’s heels using wide micropore. Check the tips are in contact with the floor in standing and that pens are firmly secured. • Time in seconds taken to walk 6 m at fast pace. A walking aid may be used if required. Assistance may be provided if necessary. • Instructions: • “When I say begin I’m going to time you walking as well and as fast as you can. Continue walking (to … point at approx. 8 metres/chair placed at 8 m mark).” • Start with the subject 1 metre before the 0 m mark. The patient should continue walking for 1 metre beyond the 6 metre line (8 m total). Start and stop timer & stride analyser when heel crosses the 0 & 6 m lines respectively. • Collect step length/BOS data from floor and remove marks afterwards using mediwipes. Base of support is measured as per the stance foot’s dot. Eg, the left base of support is the perpendicular distance of the left foot’s dot from the trajectory of the right foot dots (ascertained from the previous dot and the following dot, both made by the right foot) Scoring: 2 High Pass = Time for 6m < 13 sec 1 Low Pass = Time for 6m > 13 sec 0 Fail = Unable to complete: 6 DATA COLLECTION FORM INITIAL MEASUREMENT DATE: __ / __ / __ SUBJECT’S NAME: ____________________ SUBJECT IDENTIFICATION NO.: __ __ __ (ensure each space is filled with zeros to the left of the subjects number) PRIMARY DIAGNOSIS:__________________ Sided weakness: (L = left / R = right / B = both sides ) _____________ Hospital admission date: _____________ Rehabilitation admission date: _____________ DEMOGRAPHICS: Date of Birth: _____________ Sex: (F = Female , M = male) : ______ COGNITIVE STATUS : If problems have been identified, document MSQ score obtained during screening _____ HEALTH: List of medications: __________________________________________________ __________________________________________________________________ Other conditions: Ever (1 = yes, 2 = No) Stroke __________ Fracture of lower limb __________ Heart problems __________ Diabetes __________ Cancer __________ OA/RA __________ Parkinsons Disease __________ Respiratory Problems __________ Other (specify) __________ Do you currently have pain in either your back or either of your lower limbs?

A great A moderate A small Not at all amount amount amount 11 GUIDELINES FOR EXERCISES AND PROGRESSION FOR BOTH GROUPS: • Training should be performed for the affected side primarily; however for both where there are bilateral impairments. • Each exercise to be performed at either: • 10–15 RM (approximately – this can extend up to 15RM) 1 set daily • 2–3 sets with the 1st set as a warm up, 2nd slightly increased intensity 3rd set at 10–15 RM per day, with 1–2 minutes rest between sets (not essential for physical benefits). • “10 RM”: it is not vital to get the “10 RM”the first time. The patient may do closer to 15–20 RM the first time, and adjustments made for subsequent sets. This is beneficial for the purposes of conditioning and avoiding Delayed Onset Muscle Soreness (DOMS). • Aim for 10–15RM in the pain-free range for those with painful knees. • Instruct the patient to “do as many as you can at this level” to avoid “early” fatigue. • “Warm up” with a few repetitions of the task at a lower intensity (this will assist in determining the intensity for the first set and allow the opportunity for the patient to get the right idea). • Explain the task to the subject using demonstration or guidance if required • Patients should be encouraged to try their best each day • “Comments” to include at the bottom of the exercise sheet, may include variations made to the training environment, pain, medical issues of that day etc. • “Other practice” includes other training activities the patient is involved in, eg. walking • Record the intensity and repetitions of each set in the session on the training sheet • Frequency: Aim to do training every day, although if this is not possible simply record the reasons on the practice record sheet. Exercises are required to be performed a least 3 times weekly. It is therefore not necessary to do each exercise every day where there are time constraints. • Alternation of exercises may be necessary if patients experience soreness. Record the order exercises were performed in on the practice record sheet in the little box in the right hand side of the column • Alternation of exercises may be required if patients are not be able to do all of the exercises. • Patients are permitted to do additional practice at a lower intensity of the tasks they are practicing (eg, sit to stand from a higher height or knee extension without weights). 12 NON-WEIGHT-BEARING STRENGTHENING EXERCISE GROUP • • A lower intensity may be prescribed in the event of muscle soreness. Where individuals are unable to perform exercises on the front of the practice sheet (stepping up onto blocks), they should attempt the less difficult exercises included on the reverse side (pushing on to a set of scales in sitting and in supine with leg over the side of the bed) Sitting to standing • Measure height of seat using the ruler and tape-measure device to determine the perpendicular distance from the top of the plinth to the floor. • Foot placement to be beneath the knees. • Bottom / thigh base of support: leave to the subject to determine, although cues may be used later. 1. Use the protocol for determining the lowest possible chair height to determine starting height. Where this is to be lower than the lowest plinth height, place the subject’s feet on a block (eg, 10-15 cm high platform). 2. Repeat this at least 6 times and see if they can continue. 3. If they are able to do more than 15 repetitions, add weights to the weight belt. Tilt table Weight-Bearing Exercise • Where the non-sliding tilt table is used, place 2 sliding sheets placed on to of one another underneath the patient to reduce friction between the patient and the bed • Establish 10–15 RM by starting at the “too hard” end and making progressively easier. 1. Place a bed sheet or sliding sheets on the tilt table. 2. Strap the patient at their chest and hips (not too firmly), place foam on the tilt table at the level of the exercising knee to prevent hyper extension, and adjust shoulder pads as necessary. 3. Place the exercising foot on the phone book(s). Use between 1 and 4 phone books (ie,, 5-20 cm). 4. For the non-exercising leg, ensure that it does not assist. If the subject compensates (ie, unable to keep the non-exercising foot dorsiflexed throughout the movement), then tie, use a sling, or hold this leg. An AFO could be used to restrain PF. 5. The angle of the tilt table is measured by the inclinometer on the side of the bed near the controls, or by using a goniometer. 6. Ensure the subject’s body remains in the midline as they push, by ensuring their head is over the top of the exercising foot. 7. Manual guidance may be necessary, but try not to assist with extension of the exercising leg. 8. Progress this exercise by increasing the angle of tilt on the table before adding more phone books. Weights may be added to the tilt table in order to approximate the 10-15 RM. 13 Standing Weight-bearing Exercise 1. Place tables or chairs on 1 or both sides of the patient for safety. To reduce upper limb support, position the person next to a wall with a table on the other side. Note which side as this needs to remain consistent. 2. The exercising foot is placed on the phone book(s) while standing on the other foot. 3. The subject keeps the non-exercising foot dorsiflexed as they extend their exercising leg on the phone books. An AFO could be used to restrain PF. 4. Preferably, the hands will not be used for support on the tables. Record whether they were used on the training sheet. Practising adjacent to a wall on the exercising side may assist in guiding the patient’s alignment. 5. Progress the task by eliminating the use of hands before adding more phone books. 6. Add weights to weight belt to approximate 10–15 RM Stepping up and forwards to a block 1. Place tables or chairs on one or both sides of the subject for safety. To reduce upper limb support, position the person next to a wall with a table on the other side. Note which side as this needs to remain consistent. 2. Place a block (using phone books) on the floor in front of the stepping leg. 3. The subject begins by standing behind the block(s), places the exercising foot on the block and steps forwards and up onto it and back down to the starting position. Record the height of the block in cm. 4. Check that the patient does not push up with the other foot to achieve the step-up. 5. Preferably the hands will not be used for support on the tables. Record this on the training sheet. Practicing adjacent to a wall on the exercising side may assist in guiding the patient’s alignment. 6. The exercise is progressed by increasing the step height or adding weights to the weight belt once no hands are required to achieve 10–15 RM. Home exercise suggestions: • Standing up and sitting down • Weight-bearing extension exercise with phone book/s and table if required For subjects who are unable to perform step exercises in standing: A. Hip extension pushing onto scales in supine 1. Start with the patient supine on a plinth and the exercising closer to the edge of the bed. 2. Place the exercising leg over the side of the bed on a set of scales, so that the hip is in a neutral position and the knee at 90 degrees. Adjustments may be made with placing blocks under the scales, changing the height of the plinth to achieve the starting position. The degree of hip extension may be decreased slightly if the subject is unable to generate tension in the hips extensors in neutral or is unable to achieve this degree of passive hip extension. 3. Place a chair next to the edge of the bed if the patient requires reassurance, but do not allow them to hold onto it. 4. Instruct the patient to “push down hard through the heel of your foot to lift your bottom off the bed as hard as you can” 14 5. Record the maximum force in kg. The patient should attempt to reproduce this 6 times for each set. 6. Check the patient does not move their foot or rotate their trunk while pushing B. Hip extension pushing onto scales in sitting 1. Start with the patient sitting on a “high” chair with a set of scales under the exercising foot. A tale should be placed in front to standardise the degree of forward shoulder movement. Establish the height of the chair so as to optimise the extent of force generated with the exercising limb safely. 2. Instruct the patient to “bend forwards to rest their arms on the table in front and push hard through the heel of your left/right foot as hard as you can” 3. Record the maximum force in kg. The patient should attempt to reproduce this 10 times for each set. Home exercise suggestion: • Pushing down through the foot onto bathroom scales in sitting 15 WEIGHT-BEARING STRENGTHENING EXERCISE GROUP These subjects are not permitted to do repetitions of sit to stand practice, but may do whole walking practice. If subjects are only able to achieve grade 2 knee extension or flexion, those exercises are performed with the foot resting on a skateboard, and intensity recorded as “0 kg”. Attempt to keep the weight rack balanced either side with weights, so the full rack is lifted with each repetition. Knee Flexion Plan to perform this exercise when the gym is less busy as 2 beds are needed. 1. Sit the subject on a chair (that allows knee flexion of > 90 degrees) facing the pulleys with their back supported, feet off the ground, and arms folded. 2. Attach the pulley cuff in a figure 8 around the exercising ankle and foot and align the pulley rope to be perpendicular to the shank when the knee is 90 degrees. 3. Explain the task to the subject, and practice with no resistance. 4. Ensure the subject’s back remains in contact with the chair support. 5. Train between 30–130 degrees knee flexion. 6. Record the weight and the number of repetitions. Knee Extension 1. Sit the subject on a chair (that allows > 90 degrees knee flexion) with their back supported and facing away from the pulleys, feet off the ground, and arms folded. 2. Attach the pulley cuff in a figure 8 around the exercising ankle and foot and align the pulley rope to be perpendicular to the shank when the knee is 90 degrees. 3. Explain the task to the subject, and practice with no resistance. 4. Ensure the subject’s back remains in contact with the chair support. 5. Train between 0–130 degrees knee flexion. 6. Record the weight and the number of repetitions. Hip Abduction 1. Begin with the subject supine on a plinth placed alongside the pulleys with the exercising leg furthermost, and arms folded. A skateboard or sheet of plastic may be placed under the person’s heel to reduce the friction on the bed. Record this. 2. Rest the non-exercising leg on a stool so the hip and knee are flexed. 3. Attach the pulley cuff around the exercising ankle and align the pulley rope to be perpendicular to the leg in supine. A Zimmer splint may be required to help keep the knee extended. 4. Explain the task to the subject, and practice with no resistance. 5. Ensure the subject holds their trunk in the starting position throughout. 6. Train between 0 and 20–30 cm of hip abduction away from the midline. 7. Record the weight and number of repetitions. Hip Extension This procedure exercises the lowermost leg in sidelying. 1. Begin with the subject sidelying on a plinth with a Zimmer splint around the exercising leg. The exercising leg being lowermost, face the pulleys, and have arms resting on thigh or shoulder. 2. Place pillows under the flexed upper leg to maintain hips and spine in a neutral position. 16 3. Attach the pulley cuff around the exercising ankle and align the pulley rope to be perpendicular to the leg. 4. Explain the task to the subject, and practice with no resistance. 5. Ensure the subject holds their trunk in the starting position throughout. 6. Train through 0 - 40 degrees of hip extension from some degree of flexion. 7. Record the weight and the number of repetitions. Suggestions for home exercises: • Knee extension with weight approximating 6–1 5 RM • Hip abduction • Isometric resisted exercises: 10 seconds hold, 10 repetitions, 2 sets 17 WEIGHT-BEARING STRENGTHENING EXERCISES 18 19 NON-WEIGHT-BEARING STRENGTHENING EXERCISES 20
