For many patients with spasticity, traditional therapies have not achieved maximal outcomes. Due to common complaints such as pain, limb positioning and hygiene concerns, there has been an increase demand for other adjunctive therapies like surgeries and other interventions. This spasticity multidisciplinary clinic consisting of a physiatrist, plastic surgeon and anesthesiologist is performing a novel approach to refractory spasticity to triage and designed a treatment plan for them as routine medical care. This study will document the efficacy of this novel designed multidisciplinary approaches for intervention in complex spasticity patients, and will develop a decision-making algorithm in spasticity including both traditional treatment (i.e. botulinum toxin , bracing) and novel treatments(i.e. neurectomy , cryoneurotomy).
Many patients continue to live with disabling spasticity that negatively affects their health, independence and quality of life. For these patients, traditional therapies such as bracing, medications, and botulinum toxin have not achieved maximal outcomes. Up to one-quarter of physicians have noted to be limited by the maximal dosage of botulinum toxin allowed in their country. Due to common complaints of pain, difficulty with limb positioning, and hygiene concerns there has been an increase in demand for novel adjunctive therapies, including surgery, to improve patient outcomes.
The deisgned triage pathway is based on the diagnostic lidocaine nerve block (DNB), which is already using in Franco-European studies and has been accepted as academic abstract at the Canadian Association of Physical Medicine and Rehabilitation Annual Meeting in Gatineau Quebec in 2019. In this approach, patients are triaged for intervention based on their responses to DNB, which is applying local anesthesia to a selected nerve branch. Also the investigators of this study who have created Canada's first interdisciplinary spasticity clinic consisting of a physiatrist, plastic surgeon and anesthesiologist are working to bring the world-leading spasticity interventions to Canada and developing Canadian techniques. This includes cryoneurotomy and selective microfascicular neurectomy. Both of these techniques have been developed in this multidisciplinary clinic and in the past three years and have been published as journal articles, academic posters or presented at international congresses.This research is a pilot study to test the present current triage and treatment pathways. This study will evaluate the patients with upper limb spasticity who are going to have any of traditional treatments (i.e. bracing, botulinum toxin) or novel treatments (i.e. cryoneurotomy, tenotomy, neurotomy) as their standard medical cares. All these assessments are parts of their standard evaluations and the available data will be collected for this study. These data include their range of motions, spasticity grades, upper limb function, pain, satisfaction and injected botulinum toxin dosage. These data will be used to document the efficacy of this approach by comparing these measurements that are already done for their standard clinical care. Also, the final result will be helpful to create a Canadian algorithm to approach patients with refractory upper limb spasticity.

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Surgery | Procedure | Orthopedic surgery (i.e. tenotomy, tendon transfer) or percutaneous neuroablative procedures (i.e. cryoneurotomy) which will be done for upper limb refractory spasticity after being triaged by DNB. |

|---|---|---|
| Degree of changes in spasticity as assessed by Modified Ashworth Scale from baseline and in 1, 3, 6, 9 and 12 months after the intervention. | The test will be done by the trained assistant which is not enrolled in providing medical care. The scale has 5 grades and based on severity of spasticity the examiner will assign a number to each tested movement. The grades are shown as 0, 1, 1+, 2, 3, 4. In grade 0 patient shows no spasticity , while grade 4 means maximum spasticity and the affected limb is rigid in flexion or extention. | up to 12 months after intervention |
| Degree of changes in range of motion of tested joints as assessed by Tardieu Scale from base line and in 1, 3, 6, 9 and 12 months. | The maximum of passive range of motion in slow movement(V1) and degree of catch in speed (V3) and active range of motion will be measured by goniometer. | up to 12 months |
| Upper limb function changes as assessed by Disabilities of the Arm, Shoulder and Hand questionnaire ( DASH questionnaire)(2006). | It is a self-administered questionnaire that participants will be asked to fill out at baseline and in 1, 3, 6, 9 and 12 months. Final score will be calculated based on the provided formula and will be between (0) , which means patient has no difficulty at all and (100) which means the worst outcome. | up to 12 months |
| Patients satisfaction in achieving their goals after the procedure as assessed by Patients satisfaction in achieving their goals after the procedure as assessed by Goal Attainment Scale. | Patients satisfaction in achieving their goals after the procedure as assessed by Goal Attainment Scale38. Based on this scale participants will be asked for 3 main goals that they desire to achieve after the intervention. The baseline score will be (-1) and they will be interviewed again at 1, 3, 6, 9 and 12 months, to record how they reported their achievement. The scores of (-2), (-0.5), (0), (+1) and (+2) will be assigned if they feel that their condition is worst than before, better but not as good as expected, as expected, better than expected and much better than expected. All goals will be weighted equally, and final score will be calculated based on the available formula, in each session. The higher score is presenting of better outcome |

| Upper limb function changes as assessed by Box and Block test. | Participants will be in sitting position and will be asked to move the cubes from one part to the other part in 1 minute.The test will be done in baseline and in 1, 3,6, 9 and 12 months. | up to 12 months after procedure. |
| Changes in pain as assessed by Brief Pain Inventory Questionnaire. |

This is a self-administered questionnaire that will be provided for participants for filing out at baseline and in 1, 3, 6, 9 and 12 months after the intervention.The Patient will ask to answer each question by choosing a number between 0 to 10, and the final score is calculating by adding these numbers together and then divided by 4. The result will show the severity of patient pain out of 10. (0 means no pain and 10 means the worst pain that can be imagine) |
