Hamstring Strengthening in Hypermobile Conditions
Effects and Feasibility of Eccentric Hamstring Strengthening in Hypermobility Spectrum Disorders and Hypermobile Ehlers-Danlos Syndrome
The goal of this clinical trial is to determine how strengthening the hamstring muscles affects the knee joint in people living with hypermobility spectrum disorders (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS). The main questions it aims to answer are:
- Does hamstring strengthening reduce the looseness of the knee joint in HSD/hEDS?
- Does hamstring strengthening improve clinical outcomes like pain in people living with HSD/hEDS?
Participants will:
- Attend two exercise classes per week for 12 weeks.
- Visit the laboratory every 4-6 weeks for testing.

Experimentální: Eccentric hamstring exercise
All participants will complete a 12-week supervised lower limb strengthening program focused on eccentric hamstring loading.
Participants will complete two training sessions per week with at least 48 hours between training sessions.
Multiple classes will be offered each week to increase participation opportunity, with morning classes (8-9am) and evening classes (6-7pm) being offered on Mondays and Thursdays.
Each class will be led by the same trained kinesiologist and cover the same training protocol within a given week, regardless of the day or time.
|
The exercise intervention consists of a 12-week supervised lower limb strengthening program focused on eccentric hamstring loading.
This program is adapted from a lower limb progressive resistance training protocol that was well-tolerated and effective in people with HSD/hEDS.
Each exercise session will start with a 10-minute aerobic warm up.
This will be followed by the lower limb strengthening exercises, and a 5-minute aerobic cooldown.
The lower limb exercises will include forward lunges and seated machine weights (leg press, leg extension, leg curl, calf raise).
At weeks 6-11, eccentric hamstring loading will be initiated by utilizing the 2:1 technique of two limbs performing concentric action at once and then a single limb performing the eccentric action in a seated leg curl machine.
This is an established eccentric loading protocol for the hamstring muscle group.
