Could online pilates ease pain for those with stretchy joints?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * i. Have some form of Hypermobility Spectrum Disorders or hypermobile Ehlers-Danlos syndrome (HSD/hEDS) diagnosed by any health care provider; this would include individuals diagnosed with Joint Hypermobility Syndrome using the pre-2017 diagnostic criteria. ii. Able to read the English language and understand spoken English. iii. Willing to try to do Pilates using the 25 minute on-line training videos at least 3 times per week, unless they experience some adverse event or illness that prevents them from safely participating. Exclusion Criteria: * i. Medical restrictions (such as recent and healing surgery, fractures, comorbidities such as severe rheumatoid arthritis or neurological conditions, etc.) that prevent them from safely doing gentle exercise lying down on the floor, sitting, and standing. ii. Inability to safely stand (with or without using upper extremity for balance) for 10 consecutive minutes. iii. Recent injuries or changes in status that are not stable. This will be defined as "A significant change in your wellness due to recent injury or new symptoms in the past month that result in your wellness during the past month being very different from the past 5 months. Flare episodes that are typical for you will not prevent you from participating at this time." iv. Significantly changed treatment approach or medication within the past 3 months or be expecting to change their treatment program (including medication changes) during the study. This would make it difficult for us to know if changes are due to the Pilates class or the change in their treatment program. However, we understand that their health status may change such that they need to change their health care routine for physical and mental health. v. Currently receiving regular rehabilitation such as physical therapy, or having received physical therapy (PT) or a similar movement-based therapy (such as such as Pilates, Feldenkrais, Tai Chi, qigung, yoga) in the past 3 months. Individuals who continue to do exercises from any of these sources are not excluded, as these individuals should be stable on their current routine. vi. Currently doing more than 30 minutes/week of Pilates exercise.
