Brief summary
The objective of this study is to examine if functional high-density, high-volume chair rise training is feasible for increasing lower extremity strength without causing excessive hip pain during execution in patients with hip fracture following a municipality -based outpatient rehabilitation program. Feasibility criteria is defined as: 1) hip fracture-related pain might increase during the exercise programme, but not persistent after each session. 2) adherence to the program must be 75% or more. 3) Less than 20% drop-outs due to pain and/or discomfort during training.
Detailed description
Background and rationale: Hip fractures are associated with decrease in muscle strength, Rehabilitation after hip fractures typically include types of resistance training, functional training and cardiovascular training Factors affecting the functional prognosis after hip fracture surgery are multiple, and patients are at risk of decreased physical function new injurious falls and fractures and increased need of supportive care. Earlier research has shown that daily on weekdays, progressive knee-extension strength training (three sets with a 10RM load) is a feasible and potentially effective treatment for increasing muscle strength in patients with hip fractures when commenced few days after surgery. Extended physical therapy including strength training implemented about 6 weeks or later after hip fracture surgery seem to promote recovery of physical function. The goal of rehabilitation is to reach the highest degree of autonomy as possible, which in sarcopenic older adults requires increasing the muscle strength in the lower extremities. Higher volume resistance training has been associated with increased muscle mass and strength in both young and older populations Resistance training for elderly patients is usually done to failure to ensure adequate volume for muscle hypertrophy and strength increases. In comparison, Sit-to-stand chair exercises has earlier been executed as progressive training and shows promising results as to increasing ability to rise from a lower chair In stroke patients. Sit-to-stand exercise has been shown to be a good whole body exercise and with effects of the exercises ranging from increased leg strength to association with lower degree of dysphagia in stroke patients, when done in addition to the convalescence rehabilitation program. To the researchers knowledge there exist no other trials testing systematic use of very high training volume of sit-to-stand exercises in rehabilitation of older patients with hip fractures. This trial searches to combine training with high volume of sit-to-stand exercises with training to volitional failure on leg press and hip abductions to employ combinations of heavy, progressive resistance training and very high volume of total training (29 sets per week) Objectives The objective of this study is to examine if functional high-density, high-volume chair rise training is feasible for increasing lower extremity strength without causing excessive hip pain during execution in patients with hip fracture following a municipality -based outpatient rehabilitation program. Feasibility criteria is defined as: 1) hip fracture-related pain might increase during the exercise programme, but not persistent after each session. 2) adherence to the program must be 75% or more. 3) Less than 20% drop-outs due to pain and/or discomfort during training.
Interventions
DIETARY_SUPPLEMENTBasic intervention and nutritional intervention
The training plan is divided into 3 parts with different sub-components. There will be ongoing enrollment until 10 participants have been recruited, after which the next sub-trial will start recruitment. The intervention from the respective sub-trials is described in the individual study phases. Participants attend one-hour exercise sessions, 2 times/week for 8 weeks, in groups of 4-7 patients, supervised by 2-3 physio therapists. After completion of the physical intervention all participants are given a nutritional supplement, being a 200ml cocoa(Chokolate milk), containing 7 grams of protein, 24grams of carbohydrates, 5 grams of fat and in total 166 kilocalories. If any participant has lactose intolerance or diabetes, they are advised to bring an egg and a piece of rye bread to secure an equal amount of protein and calories.
PROCEDURESit-to-stand
First subtrial (participants 1-10): Sit-to-stand-to-sit training: Participants will be instructed to do as many sit-to-stand repetitions as possible without using their arms in a 30 second window, followed by a 30 second rest. This sequence is repeated for a total of 10 sets (a total of 10 minutes). Standard seat height of chair is 46 cm. Progression/regression: If a participant is unable to do at least 6 repetitions on the first sit-to-stand test, they are allowed to sit on a 6cm airex pillow while performing the exercise. When a single set of 12 chair rises are attained or total amount of repetitions reach 100 in 10 sets on an airex, the participant progresses to sitting on a 6-0,5cm wedge pillow, and again when the participant attains 12 rises, he/she progress to rising from the standard chair height.
PROCEDURELeg press
Second subtrial (participants 11-20): In addition to the above intervention, progressive strength training is performed on a leg press, consisting of 3 sets of 8-12RM. Participants are instructed to do as many repetitions as possible, and the weight is increased if either 12 repetitions are performed on three consecutive sets or a single set or more than 14 repetitions are completed. If fewer than 6 repetitions are performed, the weight is reduced . There is a minimum of one minute break between each set of training on the leg press.
PROCEDUREHip abduction
Third subtrial (participants 21-30): In addition to interventions described in sub-trial 1, Third subtrial will perform progressive strength training for the gluteal muscles is carried out in form of hip abduction, using rubber bands, consisting of 3 sets of 8-12RM using the same procedure as above mentioned for the leg press. Hip abduction will be performed from a standing position with a straight arm length from a wall, supporting the wall. The participant will be instructed to abduct the hip facing the wall until the foot is in contact with the wall, and then back until it touches the standing leg. Progression will be placing a rubber band just proximal to the knee with resistances being: yellow= light, red= moderate, blue= heavy. further progression will be placing the rubber band around the ankles using the same progression as above.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility of the interventions; Adherence | Measured during the 8 week intervention | Feasibility is evaluated based on adherence to the program. Adherence to the program must be 75% or more, and drop outs due to pain or discomfort during training should be no more than 20%. |
| Tolerability of the interventions; Hip fracture related pain | Measured during the 8 week intervention | Hip fracture-related pain during exercise, and dropouts. Hip fracture-related pain should not increase to more than a maximum of 3 VRS points (severe pain) during exercise and reduced thereafter, Patient rating pain on a verbal rating scale of 0-4 0: no pain, 1: slight pain, 2: Moderate pain, 3: severe pain and 4: Unbearable pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in 10m walk test, using regular walk speed and standing start. | Baseline(within the first week before starting the intervention) and immediately post intervention period | The time it takes the patient to walk 10 meters with a standing start, using walking aid if needed (19). The 10m. walk test gives an indication of a person's ability to walk and is recommended in the sarcopenia screening algorithm (20). |
| Change in Handgrip strength | Baseline(within the first week before starting the intervention) and immediately post intervention period | The maximum grip force a person can apply to a handheld dynamometer, defined as the highest of three maximum efforts (up to five) with the dominant hand. Handgrip strength is associated with total upper body strength and is recommended in the sarcopenia screening algorithm(18,20) |
| SARC-F questionnaire | Baseline(within the first week before starting the intervention) and immediately post intervention period | The Sarc-F is a 5-item questionnaire subjectively assessing strength, ability to walk, rise from a chair, walking on stairs and how often a person falls. Sarc-F is associated with the prevalence of sarcopenia and is the first test in the sarcopenia screening algorithm (20). |
| Prevalence and severity of sarcopenia | Baseline(within the first week before starting the intervention) and immediately post intervention period | Sarcopenia is defined according to the European guidelines EWSGOP2 (20), based on low muscle strength (measured as Handgrip strength or STS test), Low muscle mass (measured with bioimpedance) and low muscle function (measured with 10m walk test or other performance tests )(20). |
| Falls Efficacy Scale-International | Baseline(within the first week before starting the intervention) and immediately post intervention period | Falls Efficacy Scale-International is a measure of "concerns about falling" intended to be used in an adult and elderly population. It is a 16 item questionnaire, useful to the researchers and clinicians interested in fear of falling, with a score ranging from minimum 16 (no concern about falling) to maximum 64 (severe concern about falling) (23). |
| Quality of life by EQ5D-5L | Baseline(within the first week before starting the intervention) and immediately post intervention period | Assessment of quality of life using the EQ-5D-5L. EQ-5D is a non-disease-specific (generic) instrument developed to assess health-related quality of life. Rating instrument based on self-assessment of one's own condition. The EQ-5D is a widely used generic health-related quality of life instrument that has been used to describe population health and health outcomes in clinical trials and health economic evaluations |
| New mobility score | Baseline(within the first week before starting the intervention) and immediately post intervention period,(including pre-fracture by recall) | New Mobility Score assesses walking function; indoor, outdoors and during shopping. 0-3 points are given for each function, resulting in a score ranging from 0-9 points. A change of 1 point is considered as clinically relevant change. New mobility score is a strong predictor of mortality and other outcomes after hip fracture (21,22). |
| Quality of life by EQ-VAS | Baseline(within the first week before starting the intervention) and immediately post intervention period | Assessment of quality of life using the EQ-VAS. EQ-5D is a non-disease-specific (generic) instrument developed to assess health-related quality of life. Rating instrument based on self-assessment of one's own condition. The EQ-5D is a widely used generic health-related quality of life instrument that has been used to describe population health and health outcomes in clinical trials and health economic evaluations |
| Sit-to-stand- test | Baseline(within the first week before starting the intervention) and immediately post intervention period | Change in the number of times the patient comes to full standing position in 30 seconds from a chair with a seat height of 44-47cm. The Sit to Stand test provides a measurement of a person's lower body (particularly quadriceps) strength(18). Hip-pain will be assessed before and after (describing the maximum pain during testing) testing with the VRS (17). |
